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

AMERICAN CHAMPION

American Champion: 7FC; Cracked Wing Spar; ATA 5711

An A&P mechanic writes, “This aircraft was being modified to include the installation of wing spar inspection hole kits as supplied by DBA Rainbow Flying Service per STC number SA00527SE. A portion of the wing leading edge skin was removed and the wing spar was visually inspected as specified in the installation instructions supplied with the STC. During this visual inspection, a crack was observed on the top surface of the right wing front spar (P/N 5-146R). The crack originated at the inboard end of the aft plywood reinforcement plate. Said reinforcement plate is located on the aft side of the front spar, under the lift strut attachment fitting. The crack progressed outboard along the top surface of the spar at a slight forward angle—towards the forward plywood reinforcement plate. (It does not pass through...) bolt holes or nail holes. The aircraft maintenance records indicate a wing spar inspection had previously been completed in accordance with AD 2000-25-02. This aircraft showed no evidence of accident/incident wing damage subsequent to said inspection.”

Part Total Time: 3,177.0 hours.

 

BEECH

Beech: 58; Broken Rod-End on Nose Gear Retract Tube; ATA 3220

An unknown submitter provides the following description and photograph. “The nose gear would not lock down because of a broken rod-end (P/N ADNE5-323) on the nose gear retract rod. This rod-end connects the retract rod to the aft nose gear drag brace. (This defect) resulted in a nose gear-up landing.”

Part Total Time: 2,000.0 hours (approximately).

 

BOEING

Boeing: B727-200; Cracked Fuselage Stringers; ATA 5313

A quality assurance manager for an FAA certificated repair station (located in Asia) submitted this defect report and photographs. In part, the writer states, “This aircraft was input to Air Asia for a 4C check (time/inspection type) and CPCP (corrosion prevention control program inspection). During the CPCP (activity) visual inspection found a five inch long crack on both L/H and R/H fuselage stringers (S18A) between BS940 and BS945 (bulkhead station reference points).”

CESSNA

Cessna: 172D; Broken Ball-End on Steering Rod; ATA 3250

(A note for the occasional, uninitiated reader: there are numerous apparent and real contradictions with many terms in all disciplines. The Beech entry above references a broken “rod-end” on a retract “tube.” This Cessna entry states a “...ball-end” on a steering “rod.” Typically, convention has “tubes” as being hollow and “rods” as being solid or...less hollow. “Rod-end” can be a generic reference to any of various connection designs, allowing the tube or rod to transmit push-pull, torsion, rotary, and other forces. These terms are also frequently very specific, and may be included with the formal part name as given by the manufacturer. Here the submitter references the typical push-pull tube specifically as a “rod,” and demonstrates alternative intentions of the design. See the submitter’s note in the second paragraph. Had it not been for the close proximity of these two descriptions, this arm-chair mechanic would never have considered how confusing tubes and rods could be to other readers—Ed.)

About this Cessna 172D our anonymous mechanic writes, “The L/H side McFarlane steering rod’s ball-end broke after 215.92 hours time since new (P/N MC543022-1). (The rod shown in figure 1...) attaches to the right rudder bar assembly (P/N 0411306-14).

(Failure) of this rod-end (ball) left the R/H steering rod as the only steering (input) for the nose gear. (Note: the ‘rods’ are not solid rods; they are designed to push and not pull—they slip inside when pulled.) It requires both rods to steer (the aircraft); the R/H pedal and L/H rod will turn the nose to the right, and the L/H pedal and R/H rod will turn it to the left.

“On landing roll-out this plane began to drift to the left—the L/H rudder pedal was disconnected from the nose gear—it would not respond. (Airflow over the rudder had also diminished), causing the aircraft to drift more and more to the left with no response. As the pilot applied brakes the aircraft continued its left drift off the runway, then the nose gear collapsed.

“This aircraft had 3,321.80 hours total time. The McFarland FAA/PMA replacement Cessna part only had 216.92 hours. The rod-end (ball) had been cracked for a period of time (prior to this failure as evidenced) by rust in the crack—the remaining metal looked crystallized (see figure 2).

“After an extensive inspection of the broken parts it was found that the Cessna rod-ends (P/N S1107-3) also had thread cracks with rust. These rod-ends thread into the nose gear steering collar (Cessna P/N 0743011-4). The ball-end attaches to the nose gear steering rod (either the Cessna P/N 0543022-1, or in this case the McFarlane P/N MC0543022-1). Rod-end (P/N S1107-3) is a hollow, threaded shaft style (see figure 3) that threads into the steering collar. Both the L/H and R/H rod-ends failed at the jam-nut (see figure 4). There was no entry (into the log books) on the replacement of the L/H or R/H rod-ends (P/N S1107-3).

“The aircraft had been in a (previous) accident where the plane undershot the landing area and nosed over in snow. There was damage and repairs to the wings—and to the belly skin immediately behind the nose gear and firewall. This Cessna (1986-88) was equipped with a Landis Nose Fork (Model PA28-206) using an 8.50 x 6 nose wheel, tire, and tube. After (the accident) it had the Cessna heavy duty nose fork and a 6.00 x 6 wheel, tire, and tube.

“The Cessna rod-ends (P/N S1107-3) in question have a total time in service of 3,321.80 hours. Cessna has no time life on the hollow rods; Beechcraft also uses them, but with a time life of 2000 hours in service.


"My recommendations:

“Cessna Parts—replace the hollow rod-ends (P/N S1107-3) with a solid rod-end (P/N MS21151-3 or equivalent) by field approval, thereafter every 4,000 hours. If not...then replace the (original) hollow rod-ends every 2,000 hours or whenever damage to either the nose gear or aircraft could cause extra stress—even if there is no visible sign of damage.

“Landis Nose Fork—(with the 8.50 x 6 wheel, tire, and tube installed)—replace the hollow rod-ends (P/N S1107-3) with a solid rod-end (P/N MS21151-3 or equivalent) by field approval, thereafter every 3,000 hours. If not...then replace the (original) hollow rod-ends every 1,500 hours or whenever damage to either the nose gear or aircraft could cause extra stress—even if there is no visible sign of damage.”

A search of the FAA Service Difficulty Reporting System data base revealed at least three additional listings. Thanks for the analysis effort and the terrific hand drawings—Ed.)

Part Total Time: 216.92 hours.

 


Cessna: 750; Ruptured Nose Wheel Steering Hose; ATA 3250

A repair station technician provides the following narrative. “The nose wheel steering (centering) flexible hydraulic hose ruptured where the hose body is swaged to a 45 degree fitting attached to a bulkhead fitting in the nose wheel well. This condition allowed the loss of hydraulic fluid in the ‘A’ system. This aircraft landed without incident. The ruptured hydraulic hose (P/N AE1011889G0116) is currently made of Kevlar and is being replaced with a stainless steel braided version, along with other hoses attached to the nose gear.”

A search of the FAA Service Difficulty Reporting System data base this P/N also hits three additional times.)

Part Total Time: 7,516.0 hours.

 

DASSAULT

Dassault: Falcon 50; Damaged Flap-Well Wire Bundles; ATA 5797

“During a routine block inspection,” says a mechanic, “a visual inspection of the wings revealed multiple wires showing damage in the flap-well area forward of the inboard flaps. The cause of damage to the wire bundles F50B602101A1 and F50B602102A1 could not be determined. Some showed signs of heat damage and others seemed frayed or chaffed—or chewed. No system malfunctions were noted by the flight crew prior to the inspection. The aircraft was on an international flight prior to the inspection. The wires were replaced IAW the manufacturer’s maintenance manuals and standard practices (and additional shielding was applied). Inspection of other aircraft in the fleet showed no similar damage. (My) recommendation is to shield these wire bundles better and to pay more attention to flap well areas during preflight inspections.” (Landings noted at 7,945.)

Part Total Time: (aircraft) 10,534.6 hours.

 

PIPER

Piper: PA24-260; Failed Rudder Torque Tube; ATA 2720

An unidentified submitter states, “During maintenance run-up and taxi check (after maintenance) the left rudder torque tube broke off (P/N 2223900). It appeared to have been cracked for some time prior to failing during taxi. It is suggested the area be cleaned and inspected with a 10X magnifying glass. A borescope with a side view end could also be inserted in the tube to inspect if from the inside. If this had happened during landing and had broken at initial brake application, the aircraft would probably have departed the runway.

Part Total Time: 3,404.0 hours.

 

HELICOPTERS

BELL

Bell: UH1F; Cracked Gearbox Web Casting; ATA 6320

A technician for a helicopter operator writes, “A crack was found on the main gear box (transmission) in the vertical cast webbing above the engine to transmission drive quill (P/N204-040-016-005). The military technical manual allows ¼ inch radius/polish into the webbing. This crack has been found on three transmissions on other aircraft, with one penetrating the gear box (sufficiently) to leak fluid.”

LYCOMING

Lycoming: O-320-D2A; Sinking Carburetor Float; ATA 7322

A mechanic and pilot from Tennessee says, “The engine died on final to the airport. I pumped the throttle and the engine started running. When I retarded the throttle the engine again died. I could not get the engine to restart on the ground. Then engine was started the next day showing a fuel flow of 11 to 12 gallons per hour at idle. I removed the carburetor and (found) one pontoon of the plastic 90 per cent full of fuel.” (Aircraft is a Van’s RV-9A. Precision Airmotive carburetor, model number LW-1586; float P/N 30-804. Included note says the “...seam failed at the glue line.”)

Part Total Time: 33.0 hours.

 

ACCESSORIES

KELLY

Kelly Oil Filter: ES48109; Defective Filter; ATA 8550

(This defect report references a Continental IO-520M engine.)

A technician for an operator writes, “On disassembly of this engine rubber debris was found in the oil passage that feeds the starter adapter pilot bearing—the passage was plugged. Upon splitting the engine case debris was found in the oil passage to the #3 main bearing. Both oil cooling jets to this bearing were plugged with rubber debris. The right (jet) was plugged with a piece 5/8 inch long, the left a piece 3/16 inch. One piece of rubber debris was located in the oil passage to the #5 bearing.


“This engine had utilized Kelly Aerospace oil filters (P/N ES48109) prior to the engine disassembly. (Opening this engine’s Kelly filter indicated ...) the top rubber seal within the filter was damaged—and this damage may have occurred at the time of the filter manufacture. (Any debris) from this filter would not be caught by the filter (material) because the rubber seal is located on the oil exiting portion of the filter. This debris...may restrict the lubrication to some parts of the engine and eventually result in an engine failure.”

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.

THE DAMAGE TO THE BOLT, FLANGE MATING SURFACES AND COUPLING ARE CLEARLY NOT THE RESULT OF CORROSION BECAUSE THE SURFACES IN THE AREAS OF DAMAGE ARE CLEAN AND HAVE AN ALMOST POLISHED APPEARANCE.

THE HYDRAULIC FLUID AT A PRESSURE OF 1650 PSI WAS RELEASED INTO THE CABIN, ATOMIZING AS IT DID SO, THE DIRECTION OF THE SPRAY WAS DIRECTLY AT THE PILOT. THE POWER WIRE FOR THE HYDRAULIC PUMP ARCED AGAINST THE TUBING, IGNITING THE HYDRAULIC MIST AND IGNITING A FLASH FIRE. THE FIREBALL WAS UNABLE TO SUSTAIN ITSELF AND DID NOT IGNITE THE AIRCRAFT ALTHOUGH THE PILOT WAS SET ON FIRE, SUFFERED 1ST AND 2ND DEGREE BURNS TO HIS FACE AND RIGHT HAND. THE PASSENGER DID NOT RECEIVE ANY INJURIES AND WAS INSTRUMENTAL IN EXTINGUISHING THE PILOT, THE SYSTEM HAS BEEN IN THE ACFT SINCE MANUFACTURING, BUT DOES NOT MATCH ROUTING SHOWN IN THE IPC. AFTER A THOROUGH RECORDS SEARCH, UNABLE TO FIND ANY MENTION OF THE LINES BEING REPLACED OR INSTALLED. TUBING HAS BEEN FORWARDED TO A LAB TO DETERMINE WHAT CAUSED THE ORIGINAL TUBE FAILURE. FLUID SAMPLES OF THE AEROSHELL 41 FLUID HAVE BEEN ALSO SENT OUT TO DETERMINE IF THERE WAS ANY CONTAMINATION PRESENT. ALL THE LINES IN THE CABIN ARE BEING REPLACED WITH NEW AND PROTECTED FOR NOW WITH A FIRE SLEEVE TO ISOLATE THEM FROM EACH OTHER AND ANY POTENTIAL IGNITION SOURCE, WE ALSO CARRIED THIS OUT ON OUR OTHER DHC-2T C-FOPE ITS SETUP DOESN’T RESEMBLE ANYTHING IN THE IPC EITHER.

WHEN WE REMOVED THE NR1 CYLINDER, WE FOUND THAT THE INTAKE VALVE HAD BROKEN OFF AT THE KEEPERS AND A PIECE HAD SHOT OUT THE SIDE OF THE PORT AND LODGED ITSELF IN THE FINS OF THE NR3 CYLINDER. THERE WAS CONSIDERABLE DAMAGE TO BOTH CYLINDERS. THE REST OF THE VALVE HAS YET TO BE SEEN BUT IT IS EXPECTED TO BE FOUND ONCE WE REMOVE THE INDUCTION COVER. (TC NR 20080229012)

(CAN) WHILE IN CRUISE, THE PILOT HEARD A BANG AND EXPERIENCED A LOSS IN POWER ON THE LT ENGINE. AS THE ENGINE REMAINED RUNNING AND THERE WAS NO IMMEDIATE CONCERN FOR SAFETY THE PILOT CHOSE TO LEAVE THE ENGINE RUNNING AND SET DOWN AT THE NEAREST AIRPORT. UPON EXAMINATION OF THE ENGINE IT WAS DISCOVERED THAT THE NR1 CYLINDER INTAKE VALVE HAD FAILED AT THE TIP KEEPER LOCATION. THE DECISION WAS MADE TO REMOVE THE ENTIRE ENGINE ASSY AND RETURN IT TO THE OVERHAUL SHOP DUE TO THE LOW TIME SINCE OVERHAUL (TSO). I WOULD LIKE TO MAKE NOTE THAT THE ENGINE PARTS MANUAL IS NOT CLEAR AS TO THE STYLE OF KEEPER REQUIRED FOR THE INTAKE VALVE POSITION AND, THOUGH IT WAS NOT A CONCERN IN THIS CASE, IT COULD BECOME AN ISSUE FOR CONFUSION. THE VALVE THAT FAILED HAD A HORSESHOE STYLE KEEPER AND ROTATOR CAP ON THE TIP, WHEREAS THE PARTS MANUAL SHOWS A TAPER KEEPER WITH NO ROTATOR CAP. THEN ENGINE SHOP HAS SUBMITTED SDR NR 20080229012.
