AVIATION MAINTENANCE ALERTS

The Aviation Maintenance Alerts provide a common communication channel through which the aviation community can economically interchange service experience, cooperating in the improvement of aeronautical product durability, reliability, and safety. This publication is prepared from information submitted by those who operate and maintain civil aeronautical products. The contents include items that have been reported as significant, but have not been evaluated fully by the time the material went to press. As additional facts such as cause and corrective action are identified, the data will be published in subsequent issues of the Alerts. This procedure gives Alerts’ readers prompt notice of conditions reported via a Malfunction or Defect Report (M or D) or a Service Difficulty Report (SDR). Your comments and suggestions for improvement are always welcome. Send to: FAA; ATTN: Aviation Data Systems Branch (AFS-620); P.O. Box 25082; Oklahoma City, OK 73125-5029.

(Editor’s notes are provided for editorial clarification and enhancement within an article. They will always be recognized as italicized words bordered by parentheses.)

 

AIRPLANES

BEECH

Beech: B55; Disintegrating Fuel Cell Foam; ATA 2810

“The right wing leading edge fuel cell was removed because of a fuel leak,” states a submitting technician. “A replacement cell was ordered from a well known, leading supplier. Prior to the installation of the new (overhauled) cell, it was inspected and found to contain a large quantity of sawdust-like particles. On further inspection, the fuel cell (was found to still have) the foam-filled fuel reservoir inside. This foam was breaking down. After discussions with Raytheon’s tech support it was concluded that AD 68-26-06 had been complied with at some point in time—which required the installation of fuel reservoirs to prevent engine power loss during steep turns and on takeoff. These reservoirs had a foam insert which was compatible with 100/130 fuel. The use of 100LL, however, causes the foam to break down into fine particles that get trapped in filters and screens—potentially clogging them. This problem is addressed in service bulletin (SB) number 2109 which replaces the old style foam (P/N 369200157) with a product that is suitable for use with 100LL. We feel the SB should be an Airworthiness Directive—alerting other maintainers (who may not be aware) of this problem and its SB. Both fuel cell reservoirs (on this aircraft) now have had the foam replaced and the fuel filters, strainers, and injectors cleaned IAW SB NO. 2109.”

(Truncating the part number’s last digit finds this same defect  in the FAA Service Difficulty Reporting System data base on two additional Beech aircraft: one in 1994 and the other in 1996.)

Part Total Time: 2,616.0 hours.

 


BEECHJET

Beechjet: 400A; Cracked Horizontal Stabilizer Ribs; ATA 5511

A submitter from a repair station writes, “The horizontal stabilizer leading edge inboard ribs are cracked at the roller bracket attachment points. (I have included applicable pages of the...) Raytheon Safety Communiqué and photographs (of our aircraft’s cracked parts.) Safety Communiqué number 70 is the only published criteria concerning this problem.”

(If you enter the base part number—sans last three digits, in the FAA Service Difficulty Reporting System data base, you will receive 45 of these entries, the first this month 2005.)

CESSNA

Cessna: 150/152; Cracked Aft Fin Attach Fittings; ATA 5530

(The following safety article is published as received from the Wichita Aircraft Certification Office. Contact information can be found below the attached mechanical drawing.)

“The FAA has received reports of cracks on the two vertical tail attach fittings on Cessna 150/152 airplanes. The aft fin attach fitting is part number (p/n) 0431009. There are three dash numbers: -1, -2, and -3. Most of the 41 reports found in the FAA Service Difficulty Report (SDR) database have been the -3 part. The SDR’s are for cracked, broken or corroded attach fittings. A statistical analysis of the SDR data indicates that the problem was getting worse from 1976 through 1991. Since 1992, these analyses indicate improvement, with SDR’s reported less frequently, due to the awareness of maintenance technicians to this problem. However, the FAA wants to keep the technicians, owners and operators aware of this problem because of the way these airplanes are used. That is, the Cessna 150/152 airplanes are used for training, aerobatics and spins. These uses put additional air loads on the vertical tail surface. So, a failure of this attach fitting could be catastrophic. Past failures have occurred in the transition from the vertical straps to the lower plate portion of the fitting. Cracks tend to form in the outboard portion of the fitting, with the outboard strap failing before the inboard strap.”

HELICOPTERS

BELL

Bell: 206B; Cracked Horizontal Stabilizer Rib; ATA 5511

“During the course of a scheduled inspection,” writes a mechanic, “the R/H horizontal stabilizer was removed to troubleshoot a problem with an auxiliary strobe light that is attached to the stabilizer. During removal, the flange on the inboard rib that attaches the stabilizer to the tail boom was found cracked and separated into two pieces. Due to the location of the crack (this defect) was not visible with the stabilizer installed.” (Rib and fitting assembly P/N 206-020-123-048)

A repair station technician states, “During a 100 hour inspection, ‘play’ was noticed between the rotating and non-rotating swash-plates of the tail rotor pitch control (P/N 369D21800-501). After removal it was noted the bearing was dry and rough—records indicate (this unit was lubricated) in December of 2006.

(The FAA Service Difficulty Reporting System data base reveals this part number/defect ten times since 1995.)

POWERPLANTS

CONTINENTAL

Continental: O-200A; “Uncontained” Rocker Shafts; ATA 8530

(The following defect report combines two submissions from the same source concerning the same problem found on two different O200 engines and their Cub Crafters/Piper aircraft. Permission has been extended for contact information, found at the end of this discussion.)

(First Engine)

A mechanic/operator of Smokey Mountain Aviation writes in this first of two reports, “An owner found oil dripping from the cowl of the aircraft. On inspection (I found) the rocker shaft on cylinder number four had cut a hole through the rocker cover. (Note: the new O-200A engines have a ‘flat’ cut into the rocker shaft and a set screw in the center boss to retain the shaft. This shaft is sharp on its ends (unlike the old style) and has a cut mark across the end of the shaft—used in aligning the ‘flat’ for the set screw. This engine was removed and sent to TCM for warranty repair. It was then reinstalled on the aircraft. TCM told the owner they are working on a revised cylinder due to this problem. At some later date TCM will send us four new modified cylinders to install on this engine.

“Problem: the set screw is (P/N) MS51963-64: it uses no ‘Locktite’ or mechanical type lock. (Additionally,) the flat in the rocker shaft is not deep enough to provide adequate locking.” (An attached letter from this submitter provides additional descriptions. He continues here, in part:) “As you can see in the pictures provided with this report, the rocker shaft on cylinder number four has a hole cut in the rocker cover. TCM told us not to open the covers as they wanted to be able to see exactly the problem (and its cause). After working on the (other aircraft...see next) there is no doubt the Allen screws backed out, allowing the shaft to float free. The sharp edge of the shaft cut through the cover.”

“Recommendation: The shaft should have the flat cut deeper, and the boss should have a small pilot hole drilled into it to accept a mechanical lock tab with a bolt installed (instead of the set screw). (Another proposed solution would be...) to remove the (new style) shaft (P/N 654375) and set screw (P/N MS51963-64) and discard (both). Install the old style shaft (P/N 21153) that has worked with no problems for sixty years.” (Part time on this particular engine: 66.2 hours.)

(Second Engine 3 months later)

“As per the owner’s request I removed all four rocker covers to inspect the rocker shaft and set screws. I found all four set screws loose, and all four shafts moved towards the intake side of the bosses. None have cut the rocker covers yet (but I estimate this would have happened with another 20 hours of operation.)"

“As you can see in the pictures provided with this report, the screw shown with the Allen wrench was found loose. This allowed the shaft to move towards the intake side of the cylinder. You can see clearly...the shaft is not centered in the bosses.” (Part total time on this second engine: 38.08 hours.)

Part Total Times: 66.20 and 38.08 (respectively).

 

Continental: IO-240-B17B; Jammed Fuel Pump Shaft; ATA 7314

(A mechanic describes this engine defect found on a Diamond DA-20 aircraft. Readers should note the relevant Diamond DA20 aircraft defect report in this issue of the Alerts.)

“The mixture control shaft on the engine driven fuel pump froze up at half-travel, between full rich and idle cut-off. This created a lean mixture which starved the engine for fuel. The mixture control was (first) disconnected from the fuel pump, then the fuel pump control shaft had to be freed up. The mixture cable was completely free (with no binding) once disconnected from the fuel pump. This fuel pump (P/N 649368-49A1) was replaced and sent back to the factory.”

(The FAA Service Difficulty Reporting System data base reveals 4 entries for the fuel pump part number. Truncate the last four digits and the list expands to 16—including Cessna and Piper pumps/parts—all in the 7314 JASC code.)

Part Total Time: 380.4 hours.

 


P&W

P&W: PT6A; Starter/Generator Discharge Damage; ATA 2435

(The following advisory from Transport Canada is reprinted here for enhanced dissemination. The FAA Service Difficulty Reporting System data base finds 73 defect reports since 1993 for this manufacturer and JASC/ATA code.)

Superior: P/N SA52006-A20P; Cracked Cylinder; ATA 8530

An unidentified submitter writes, “Both cylinders (numbers 3 and 4) have visible cracks originating at the exhaust valve seat.” (The engine is listed as a Continental IO-520-F hanging on a Cessna U206F.)

Part Total Time: 847.9 hours.

 


Superior: P/N SA52006-A20P; Cracked Cylinder; ATA 8530

(The previous submitter again finds the same defect on the same type engine and airplane. As indicated, the cylinder manufacturer and part number are also the same. Part number SA52006-A20P finds four additional 8530 defect entries in the FAA Service Difficulty Reporting System data base since 2006. The seven digit base number provides 47 entries since 1998. How large would this number be if everyone reported their cracked cylinders?)

“The cylinder head has a crack beginning at the intake port and extending to the upper spark plug hole.”

(The enclosed black and white photos were similar to the previous entry. Thanks for the pictures—very ...painful to see—Ed.)

Part Total Time: 1,790.9 hours.

 

AIR NOTES

INTERNET SERVICE DIFFICULTY REPORTING (iSDR) WEB SITE

The Federal Aviation Administration (FAA) Internet Service Difficulty Reporting (iSDR) web site is the front-end for the Service Difficulty Reporting System (SDRS) data base that is maintained by the Aviation Data Systems Branch, AFS-620, in Oklahoma City, Oklahoma. The iSDR web site supports the Flight Standards Service (AFS), Service Difficulty Program by providing the aviation community with a voluntary and electronic means to conveniently submit in-service reports of failures, malfunctions, or defects on aeronautical products. The objective of the Service Difficulty Program is to achieve prompt correction of conditions adversely affecting continued airworthiness of aeronautical products. To accomplish this, Malfunction or Defect Reports (M or Ds) or Service Difficulty Reports (SDRs) as they are commonly called, are collected, converted into a common SDR format, stored, and made available to the appropriate segments of the FAA, the aviation community, and the general public for review and analysis. SDR data is accessible through the “Query SDR data” feature on the iSDR web site at: http://av-info.faa.gov/SDRX/ .

In the past, the last two pages of the Alerts contained a paper copy of FAA Form 8010-4, Malfunction or Defect Report. To meet the requirements of *Section 508, this form will no longer be published in the Alerts; however, the form is available on the Internet at: http://forms.faa.gov/forms/faa8010‑4.pdf . You can still download and complete the form as you have in the past.

*Section 508 was enacted to eliminate barriers in information technology, to make available new opportunities for people with disabilities, and to encourage development of technologies that will help achieve these goals.

A report should be filed whenever a system, component, or part of an aircraft, powerplant, propeller, or appliance fails to function in a normal or usual manner. In addition, if a system, component, or part of an aircraft, powerplant, propeller, or appliance has a flaw or imperfection, which impairs or may impair its future function, it is considered defective and should be reported under the Service Difficulty Program.

The collection, collation, analysis of data, and the rapid dissemination of mechanical discrepancies, alerts, and trend information to the appropriate segments of the FAA and the aviation community provides an effective and economical method of ensuring future aviation safety.

The FAA analyzes SDR data for safety implications and reviews the data to identify possible trends that may not be apparent regionally or to individual operators. As a result, the FAA may disseminate safety information to a particular section of the aviation community. The FAA also may adopt new regulations or issue airworthiness directives (ADs) to address a specific problem.


The iSDR web site provides an electronic means for the general aviation community to voluntarily submit reports, and may serve as an alternative means for operators and air agencies to comply with the reporting requirements of 14 Title of the Code of Federal Regulations (CFR) Section 121.703, 125.409, 135.415, and 145.221, if accepted by their certificate-holding district office. FAA Aviation Safety Inspectors may also report service difficulty information when they conduct routine aircraft maintenance surveillance as well as accident and incident investigations.

The SDRS data base contains records dating back to 1974. At the current time, we are receiving approximately 40,000 records per year. Reports may be submitted to the iSDR web site on active data entry form or submitted hardcopy to the address below.

BOTH AIRFRAME AND APU MFG TECH REPS INVOLVED IN THE (4) DAY TROUBLESHOOTING PROCESS. THERE WERE SEVERAL ATTEMPTS TO START THE APU EACH RESULTING IN AN ABORTED START. REMOVED IGNITORS TO INSPECT FOR DAMAGE AND LARGE QUANTIY OF TRAPPED FUEL FLOWED FROM IGNITER MOUNTING BOSS HOLE. DUE TO A OIL VAPOR EJECTOR MOD TO THIS APU, THE PLENUM DRAIN , THAT WOULD NORMALLY ALLOW RAW FUEL TO DRAIN OVERBOARD IS USED TO OPERATE A VENTURI-TYPE EJECTOR. THE CAUSE OF THE NON-START WAS FUEL BYPASSING THE PARTIALLY FAILED FUEL SHUTOFF VLV ( WE FOUND AN O-RING SECTION STUCK IN PLUNGER ASSY), CAUSING A FLOOD START ON THE APU. THE HIGH ELECTRICAL LOADS AND LOW ACCEL SPEEDS WERE THE DIRECT RESULT OF THE UNUSED FUEL FILLING UP THE THE COMBUSTION PLENUM (COMBUSTION TURBINE WAS TRYING TO COMPRESS LIQUID FUEL DURING START CYCLE DRAGGING DOWN THE STARTER/GEN).THERE WERE NUMEROUS ERRORS FOUND THE MAINT INSTRUCTIONS AND OPERATING DESCRIPTIONS.

ON FURTHER INSPECTION, THE FUEL CELL STILL HAD THE FOAM FILLED FUEL RESERVOIR INSIDE. THIS FOAM WAS BREAKING DOWN. AFTER DISCUSSIONS WITH MFG TECH SUPPORT IT WAS CONCLUDED THAT AD68-26-06 HAD BEEN COMPLIED WITH AT SOME POINT OF TIME WHICH REQUIRED THE INSTALLATION OF FUEL RESERVOIRS TO PREVENT ENGINE POWER LOSS DURING STEEP TURNS ON TAKEOFF. THESE RESERVOIRS HAD A FOAM INSERT WHICH WAS COMPATIBLE WITH 100/130 FUEL. THE USE OF 100LL HOWEVER CAUSES THE FOAM TO BREAK DOWN INTO FINE PARTICLES THAT GET TRAPPED IN FILTERS AND SCREENS, AND POTENTIALLY CLOGGING THEM.

AFTER PROPER INSTALLATION OF WIRING AND SUBSEQUENT OPS CHECK, THE MOTOR AND SYS, THE AIR CONDITIONER WOULD CYCLE IN AND OUT OF ITS SOFT START CYCLE. THIS IN TURN CREATED EXCESSIVE HEAT IN THE LOAD RESISTOR CIRCUIT. THIS CYCLING CONTINUED UNTIL AT SOME POINT THE SOFT START CIRCUIT FAILED, WHICH CAUSED THE LOAD RESISTOR TO OVERHEAT AND MELT THE PHENOLIC BLOCK SHIELDS WHICH CAUGHT FIRE AND DAMAGED THE IMMEDIATE SURROUNDING STRUCTURE OF THE NOSE COMPARTMENT.

BOTH VALVES WERE REMOVED FROM THE CYL AND THE WIRE THAT WAS NOTICED DURING BOROSCOPING FELL OUT. UPON INVESTIGATION OF THE WIRE, IT WAS DETERMINED THAT THIS WIRE WAS FROM A SCAT HOSE WHICH WAS ATTACHED TO THE CARBURATOR AIR BOX. THE WIRE WAS APPROX 3 INCHES LONG AND WAS SUCKED UP THROUGH THE AIR BOX, CARBURATOR, INDUCTION SYS AND RT INTO THE CYL. DURING CLOSE INSP OF THE WIRE, CHAF MARKS WERE NOTICED ON THE WIRE WHERE IT HAD BEEN RUBBING ON THE EDGE OF THE DUCT OF THE AIRBOX. PROCEDURES WHEN INSTALLING SCAT HOSES SHOULD ENSURE THAT THE WIRE IS EXTERNAL OF THE DUCT BEING ATTACHED TO, SO THE WIRE CAN BE CLAMPED DOWN BY THE CLAMP SECURING THE SCAT HOSE. (TC NR 20071002004)

HYDRAULIC SYSTEM

APPROXIMATELY 40 MIN IN TO PLANNED FLIGHT, WHILE AT FL410, IN FINAL CRUISE CONDITION, A WHITE ADVISORY CAS MESSAGE APPEARED INDICATING (MAIN HYD QTY LOW). FLIGHT CREW OPENED THE APPROPRIATE CREW CHECKLIST AND FLIGHT MANUAL AND REFERENCED THE CHECKLIST WHICH SAID (MAIN HYDRAULIC QUANTITY IS LOW), WITH NO ACTION REQUIRED. THE PF DIRECTED THE PNF TO REFER TO ANY ABNORMAL PROCEDURES OR ANY EMERGENCY CHECKLIST PAGE PROCEDURES AS A PRECAUTION FOR LOSS OF HYDRAULIC QUANTITY OR PRESSURE. THE CREW REVIEWED THESE PROCEDURES AND CONTINUED IN CRUISE. APPROX 15 MIN LATER, DURING DESCENT, A WHITE (L HYD PUMP LO) CAS MESSAGE BEGAN TO APPEAR INTERMITTENTLY, AND HYD PRESSURE FLUCTUATIONS WERE NOTED ON THE PRESSURE INDICATION. APPROXIMATELY 10 MIN LATER, A DROP IN MAIN HYD PRESSURE TO 70 PSI AND ILLUMINATION OF AMBER (MAIN HYD PRESS) AND (SPOILER FAIL) CAS MESSAGES WAS NOTED. THE CREW DIVERTED, COMPLETED ABNORMAL CHECKLIST PROCEDURES, DECLARED AN EMERGENCY, AND EXECUTED A SAFE LANDING. INSP OF THE AC REVEALED THAT THE LT MAIN HYD PRESS SWITCH (S9) HAD FAILED, ALLOWING THE HYD FLUID TO ESCAPE UNDER PUMP PRESSURE UNTIL SUFFICIENT QUANTITY WAS LOST WHICH RESULTED IN CAVITATIONS OF BOTH LT AND RT HYD PUMPS. THIS CAVITATIONS APPARENTLY CAUSED PRESSURE SPIKES OF SUFFICIENT FORCE THAT BOTH PUMP PRESSURE OUTPUT FLEXIBLE HOSES WERE RUPTURED. THIS CAUSED THE FAILURE OF BOTH PUMPS, SUSPECTED TO HAVE CAUSED THE LANDING GEAR CONTROL VALVE TO FAIL AS WELL. THIS VALVE WAS FOUND INOPERATIVE DURING POS-REPAIR FUNCTIONAL CHECKS. THE LANDING GEAR FAILED TO RETRACT WHEN SELECTED UP WHILE THE AC WAS ON JACKS WITH A HYD POWER UNIT PROVIDING PRESSURE. BASED ON THE DAMAGE THAT WAS FOUND ON THE PRESSURE SWITCH (S9), THE PROBABLE CAUSE OF SWITCH FAILURE STEMS FROM PRESSURE SPIKES WITHIN THE HYDRAULIC SYS, OR INADEQUATE DESIGN OF THE SWITCH ASSY. MFG TECH SERVICES WAS NOTIFIED OF THE ISSUE AND ADVISED THAT THEY ARE AWARE OF OTHER SWITCH FAILURES. RECOMMEND THAT A REVIEW OF THE HYD SYS BE CONDUCTED TO DETERMINE IF PRESSURE SPIKES ARE EVIDENT, ESPECIALLY DURING HIGH FLOW/HIGH PRESSURE SITUATIONS. I WOULD ALSO STRONGLY URGE THAT MFG INSTALL HYD FUSES IN THE SUPPLY LINES TO THE 2 PRESSURE SWITCHES (S8 AND S9). IF A FUSE HAD BEEN INSTALLED, THIS SWITCH FAILURE WOULD HAVE RESULTED IN ONLY A VERY SMALL LOSS OF HYDRAULIC FLUID, AND THE CREW WOULD HAVE MANAGED THE INDICATED CAS MESSAGE AS A POSSIBLE SWITCH FAILURE, SINCE PRESSURE INDICATIONS FROM A SEPARATE TRANSDUCER WOULD HAVE INDICATED NORMAL PUMP OUTPUT. THIS FAILURE RESULTED IN A REPAIR THAT EXCEEDED $36,000.00 AND AN AC OUT OF SERVICE FOR 5 DAYS. IF A HYDRAULIC FUSE HAD BEEN INSTALLED AND FUNCTIONED CORRECTLY, THE REPAIR COST WOULD HAVE BEEN $2,000.00 WITH 1-2 DAYS OUT OF SERVICE. (K)

THE MOUNT HAD BEEN REPAIRED BY WELDING AND ONE WELD WAS A COLD WELD THAT CRACKED AND ALLOWED MOISTURE INTO THE INSIDE OF THE TUBING. ANNUAL INSP 35 HOURS BEFORE FAILURE. THE MOUNT FAILED ON A SOFT FIELD LANDING AND CAUSED SUBSTANTIAL DAMAGE AFTER AN ENGINE FAILURE. IN MY OPINION THE THIN WALL FROM THE CORROSION IS WHY THE MOUNT FAILED. RECOMMENDATIONS TO PREVENT SUCH RECURRENCES ARE TO INSPECT ALL WELDS FOR CRACKS, ESPECIALLY FIELD REPAIRS. THESE FIELD REPAIR WELDS NEED TO BE EXAMINED FOR THE QUALITY OF THE WELD, CRACKS AND PIN HOLES EACH ANNUAL INSPECT8IO OR 100 HOUR INSPECTION. ANY WELDS OR REPAIRS IN QUESTION SHOULD BE REDONE, ALSO THE TUBING SHOULD BE PUNCH TESTED EACH ANNUAL INSPECTION. THE PUNCH TEST INFORMATION IN SB NR 528D AND AD 99-01-05 LATEST REVISION ON WING STRUT CAN BE USED AND ADOPTED TO DETERMINE IF MOUNT NEEDS REPLACEMENT OR REPAIR DUE TO CORROSION FRO THE INSIDE CAUSING THIN WALL THICKNESS.

HYD SYSTEM

(CAN) ON THE 21ST OF AUGUST 2007, MAINTENANCE RECEIVED A CALL THAT AN AC HAD A HYDR FLUID LEAK. A RESCUE MISSION WAS DISPATCHED TO THE AC. UPON INVESTIGATION ONCE MAINT ARRIVED AT LOCATION IT WAS FOUND THAT THE NR 1 ENG HYDR FILTER HSG WAS LEAKING. AFTER DISASSEMBLY, IT WAS NOTED THAT THERE WAS A CRACK IN THE TREADS RUNNING .5 AROUND THE DIAMETER. THE HYDR FILTER WAS ISOLATED FROM THE SYS, THE SYS TOPPED UP WITH FLUID, AND A LEAK RUN PERFORMED BEFORE RETURNING TO DEPARTURE WITHOUT PASSENGERS. IT HAS BEEN DETERMINED THROUGH AN INVESTIGATION THAT THE FAILURE WAS A DIRECT RESULT OF THE USAGE OF THE WRONG PN O-RING. THE O-RING THAT WAS FOUND INSTALLED ON THE FILTER HOUSING IS OF THE SAME OUTER DIAMETER AS THE PROPER ONE (P/N MS28778-16) CALLED FOR IN THE IPC, BUT TWICE THE THICKNESS. THIS CAUSED THE FILTER HOUSING TO REACH ITS RATED TORQUE VALUE BEFORE IT WAS COMPLETELY SEATED, THIS IN TURN RESULTED IN A MAINT PERSON OVERTORQUING THE HSG IN AN ATTEMPT TO SEAT IT PROPERLY. IT APPEARS THAT THE PERSON WHO CHANGED IT OUT DID SO WITHOUT RESEARCHING FOR THE PROPER PN IN THE IPC. A COMPANY MAINT ALERT HAS BEEN RAISED ON THE REQUIREMENT TO ONLY USE PN IDENTIFIED IN THE SPECIFIC AIRCRAFTS IPC OR CMM.

HORN AND LIGHT. FROM THE HOVER THEY ACCELERATED TO 60 KNOTS, AT WHICH TIME THE HYD ON/OFF SWITCH ON THE COLLECTIVE WAS SELECTED TO THE HYD OFF POSITION, AND THEY MAINTAINED 60 KNOTS THROUGHOUT THE CIRCUIT. ON DOWNWIND FOR EAST LIMA TAXIWAY AT 500 FEET ABOVE GROUND. THE PILOT IN COMMAND WAS INFORMED TO WIDEN OUT HIS CIRCUIT SO THAT HE WOULD NOT HAVE TO USE ANY STEEP TURNS ON BASE AND FINAL. AT THIS TIME HE INITIATED A 10 DEGREE BANK TURN TO THE LT WITH THE HYD OFF AND AT 60 KNOTS. THE AC IMMEDIATELY ROLLED 90 DEGREES TO THE RT, AND THEN THE CYCLIC MOVED HARD TO THE LT CAUSING THE AC TO RIGHT ITSELF BACK TO A LEVEL ATTITUDE. THE TRAINING PILOT IMMEDIATELY TURNED ON THE COLLECTIVE HYD SWITCH AND RESTORED THE HYD TO NORMAL, AND THE AC FLEW COMPLETELY NORMAL THE FLIGHT WAS TERMINATED. THE ROLL TO THE RT AND BACK TO THE LT LASTED 2 TO 3 SECONDS AT THE MOST. PRIOR TO THE FLIGHT, THE FLIGHT CONTROLS AND HYD ACCUMULATORS WERE CHECKED FOR PROPER OPERATION, THE HYD TEST BUTTON ON THE COLLECTIVE WAS FUNCTION TESTED AND FOUND TO WORK CORRECTLY. WHEN THE HYD TEST BUTTON WAS RESET TO ON, IT REQUIRED 3 TO 5 SECONDS FOR THE HYDRALIC LIGHT AND THE HORN TO GO OUT IAW NORMAL. NO EMERGENCY WAS DECLARED AND THE AC WAS LANDED WITH OUT DAMAGE OR INJURY TO PERSONS OR PROPERTY. (TC NR 20080115009)
