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 Mechanical Reliability Report (MRR), 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

APEX

Apex; CAP 230-232; Notice of In-Flight Structural Failure; ATA (unknown)

A recent fatality during an aerobatic championship in Saint Yan, France, has given cause for the French aviation authorities to ground Apex aircraft, CAP models 230, 231, 231EX, and 232 as of August 31, 2005. Mechanical descriptions of the specific structural failure have yet to be forwarded (or released) as of September 6, 2005. A records search indicates American registrations for these type aircraft. Their “N” numbers are 3434F, 232LR, 232DE, 659DM, 232MG, 930RM, 232DD, and 862DM. Though the French Emergency Airworthiness Directive (EAD No. UF-2005-156) does not apply to these U.S. aircraft, prudent attention and caution should be exercised. (For further information, contact Mr. S. M. Nagarajan, Aerospace Engineer: Small Airplane Directorate, ACE-112, 901 Locust, Room 301, Kansas City, MO., 64106; phone 816-329-4145.)

 

BEECHCRAFT

Beechcraft; G33; Loose Nose Gear Steering Rod-End; ATA 3250

A mechanic describes finding the rod-end (P/N 35-820045) loose on the nose gear steering push-pull tube (P/N 35-825044-6). This connecting terminal slides into the tube’s end and is mechanically fastened by two 5/32-inch solid rivets clocked at 90 degrees. “(The) rivets were not properly driven due to (compression) inside the hollow portion of the tube, instead of (compressing) at the shop head, allowing the rod-end to come loose. Separation would cause loss of nose steering control. I recommend replacement of the solid rivets with four CR3213-5-2 CherryMax Rivets in the original holes.”

Part Total Time:  7,457.0 hours.

 


CANADAIR

Canadair; CL-600-2B16; Cut (...sawed) Electrical Conduit; ATA 3340

A repair station technician investigates an intermittent circuit breaker fault for this aircraft’s upper anti-collision light. “...(I) discovered the L/H elevator control cable had torn through the wiring conduit in the vertical stabilizer. The cable wore through the conduit and shorted out the wiring for the upper beacon. (I) repaired the wiring conduit, replaced the wiring, and replaced the control cable in accordance with the manufacturer’s instructions.” He describes ensuring sufficient clearance between the cable and surrounding conduits, but wonders about the origins of this defect. “(It) is unclear if the conduit was installed at the factory or at the time of (aircraft) completion. (I) suggest inspection of this area on other, similar aircraft. (It is a) difficult (defect) to notice due to the accessibility of this area in the tail.” (The part number for this particular electrical conduit segment was not provided.)

 

This is a close-up, coolor picture showing the described flight control cable positioned approximately half-way through the 3/8 inch diameter aluminum electrical conduit--a result of sawing abrasion.

Part Total Time:  (unknown).

 

CESSNA

Cessna; 172P; Defect in New Fuel Tank; ATA 2810

A mechanic writes, “During installation of a new tank (P/N 0526000-58) it was discovered the bungs for installing the fuel strainer assemblies have been brazed to the tank inversely. The bung that should have been brazed at the aft location was brazed in the forward mount, and the bung that should have brazed in the forward mount was brazed into the aft mount.” (No other information accompanied this submission.)

Part Total Time:  0.0 hours.

 

Cessna; 182T; Contaminated Boost Pump; ATA 2822

A repair station technician gives the following description of a returned Weldon fuel pump (P/N A8160-D): “(I) received this boost pump for warranty credit with a customer complaint of ‘...fuel boost pump pops circuit breaker.’ Preliminary inspection of the pump revealed foreign material in the inlet port. Further inspection revealed the foreign material tried to pass through the pump and had locked the rotor in the insert. This would


cause the pump to draw high amps. This is the second time this problem has been seen in the last four months.” (Reference another C182 in last May’s Alerts.)

Part Total Time:  166.4.

 

Cessna; 402C; Frayed Nose Gear Steering Cables; ATA 3250

An inspection of this aircraft revealed the R/H nose steering cable (P/N 500000-124) “...blended and frayed.” This operator states, “New Cessna cables (stainless steel) last only a fraction of the time as the old style cables. (This defect) has become a much more common occurrence.” (See last month’s Alerts for a similar Cessna 441 cable problem.)

Part Total Time: (unknown).

 

Cessna; 501; Broken Seat Frame; ATA 2510

An upper chair base assembly (P/N 5519015-6) was found cracked at the attach points. The submitter believes stress and metal fatigue are the probable causes. This chair was repaired in accordance with Aviation Fabricators  STO1J043WI (supplemental type certificate) structural seat repair. (Two photographs are shown below. Reference last July’s Alerts for very similar report.)

Cessna; 750; Thrust Reverser Malfunction; ATA 7830

“The L/H thrust reverser performed an un-commanded stow during thrust reverser use after landing,” writes a mechanic. “After accessing the throttle quadrant, it was noticed the wires connected to the L/H deploy switch were stretched very tight when the ‘T/R’ piggy-back levers were in the deploy position. After running diagnostics using software provided by Cessna, it was determined the deploy switch was faulty. During the process of accessing the wires to replace the switch, a wire was found to be broken where it was spliced. The shrink-wrap around the wire bundle contributed to the intermittent nature of the defect. The splice was repaired and an operational check of the T/R system confirmed the system had been fixed.”

Part Total Time:  115.7 hours.

 

DASSAULT

Dassault; F10; Broken Wheel Bolts; ATA 3246

“A broken wheel bolt (P/N GYS185-25) was noticed during a tire pressure check,” writes this repair station technician. “The wheel cover was removed to investigate. All ten bolts were NDT’d (non-destructive testing) by magnetic particle inspection and three other bolts were found cracked. Part cycles (landings) since overhaul is 176.” (The aircraft’s wheel manufacture: Aircraft Braking Systems Corporation: P/N 5000400).

Part Total Time:  (unknown).

 


Dassault; F50EX; Oil Tank Crack; ATA 7261

Excessive oil covering number three engine and its nacelle quickly caught this mechanic’s attention on postflight inspection. Oil had collected primarily around the oil tank. Subsequently, both engine and cowling were cleaned prior to engine run. Shortly after engine start “...oil was observed coming from a small .50 inch crack in the oil tank wall. (This) crack was located approximately 2.25 inches below the top of the tank and 3.50 inches above and left of the oil filler cap. (It) appears to originate from an internal weld, or a welded baffle internal to the tank assembly.” He describes installing a new Honeywell direct replacement tank (P/N 3060720-4), but noticed this new tank had a similar, possible defect of a dent or depression in the exact same area of the original cracked tank. Having discussed this with Honeywell, an upgraded tank (P/N 3060720-5) was to be shipped for exchange. (Engine listed is Honeywell TFE731-2B.)

Part Total Time:  2,873.6 hours.

 

Dassault; F2000; Arcing Wire Bundle; ATA 1497

A technician discovered a fractured wire harness (P/N FSFB641103A3) under the copilot’s seat showing evidence of arcing, including “...copper globules.” He emphasizes had papers and other items found stowage in this area it would certainly present a fire hazard. He makes two suggestions: the particular harness should be of heavier construction, and close attention should be given to routing and clamping. The circuit breaker, too, was apparently slow to react. (The second letter “S” in the above part number was barely discernable in this submission.)

Part Total Time:  6,108.0 hours.

 

ISRAEL AIRCRAFT INDUSTRIES

Israel Aircraft Industries; 1124; Arcing Wire Bundle; ATA 1497

A repair station technician describes finding “...a wire harness chaffing and arcing in the area of the cockpit entrance-overhead. This problem has been addressed by IAI Service Bulletin SB 1124-24A-154. Consideration should be given to make this an AD (Airworthiness Directive) due to the potential of in-flight smoke and fire.” (The Service Bulletin calls for a one-time inspection of the bundle above and near the N0-Smoking/Seatbelts sign. As described, a door hinge in the vicinity has potential to wear on improperly protected or routed wires. As you projected, this Service Bulletin became an Australian directive, AD-IAI-W-28 on April 20, 2005. Whether or not it becomes an FAA directive is a question still in the pipeline.)

Part Total Time:  (unknown).

 

PIPER

Piper; PA46; Chafed Engine Mount; ATA 7120

A technician writes, “During a normal event inspection, the air shield was found chaffing against the upper R/H engine mount leg where it passes through the baffle shield (P/N 102403-053) for the plenum assembly. This type of a problem has been discovered on other model aircraft, and it is recommended close inspection be given to the area where baffling could be cutting into the engine mount. Both times this (defect) was found, the engine mounts had to be repaired by approved welding methods and authorized repair facilities.” (The SDR data base reflects another, very similar chafing discrepancy.)

Part Total Time:  747.4 hours.

 


Piper; PA600; Main Landing Gear Strut Cracks; ATA 3213

(The following is a composite description of three submissions from the same mechanic for two aircraft: a PA600 and a PA601.) The left main landing gear strut bottom collar is “...separating from the tube due to insufficient penetration when the part was furnace brazed or silver-soldered together. The working cylinder (P/N 400054-01) collar caused the part to work and crack the boss. (I) recommend inspection of the collar at the bottom of the gear strut for any movement or working between the collar and the strut cylinder assembly. Dye check the collar where the part is machined for clearance on the torque links.”

Part Total Times: 3,968.5 and 4,148.0 hours (respectively).

HELICOPTERS

SCHWEIZER

Schweizer; 269C-1; Tail Rotor Failure; ATA 6510

The submitter describes this aircraft experiencing tail rotor failure while in cruise flight at approximately 700 feet. “The pilot went to flat pitch, put the helicopter into a dive to avoid rotation from torque, performed full autorotation to the ground, (and incurred) no damage to the helicopter or injuries to the occupants. The drive gear on the tail rotor input shaft was stripped, as was the forward gear on the tail rotor drive shaft. (We) inspected our three remaining helicopters having 500 to 4,775 hours time on these components—no discrepancies were noted. (I) suspect a possible metal problem. The current inspection (interval) is 600 and 1200 hours, or every 24 months. (I recommend) possibly lowering the inspection intervals to 300 hours. This helicopter was 30 hours from its 1200 hour (inspection).”  (The spline P/N is 269A5430-1. The main rotor belt drive assembly is listed as P/N 269A5510.)

Part Total Time:  1,138.8 hours.

 

Schweizer; 269C; Jammed Cyclic Stick; ATA 6710

“During descent to landing,” writes the mechanic, “...the cyclic stick jammed, not allowing any lateral movement to the right beyond neutral position. This was caused by the spring tube coming out of the trim housing, locking the trim arm at a three-quarter extended position (lateral trim assembly P/N 269A7316-13). The spring tube came out of the trim housing due to a failure of the epoxy that holds it in. This (particular) new trim actuator has a different color epoxy (white) than the older actuator epoxy (green).”

Part Total Time:  152.3 hours.

 


POWERPLANTS

CONTINENTAL

Continental; IO-520-F; Defective Starter Adapter; ATA 8011

The submitter states, “The starter adapter (P/N 643259) was removed due to damage caused during a ‘kick-back’. Inspection found the bearing retaining holes had been knurled at the factory, misaligned, and coated with a greenish bearing retaining compound. The starter adapter worm drive showed signs of a heavy side load. This caused the starter adapter to bind and not release. This housing has an inspection stamp of (identification number withheld) and a date stamp of September 15, 2003.”

Part Total Time:  (not provided).

 

Continental; IO-550-F; Broken Crankshaft Bearing; ATA 8520

A repair station mechanic disassembles this engine and notes a broken bearing shell, number two “...from the rear saddle. It appears the bearing has worked—and is polished as result.” Fretting on the parting surfaces and a malformed bearing tang also provide evidence for a working bearing (P/N SA634503M010). (Great pictures! Next time, if possible, please “flesh-out” a few more details: TSO, TT, Part Times, operating conditions and earnest speculation—they all provide insight and education. Thanks—Ed.)

ACCESSORIES

TCM MAGNETO

TCM Magneto; 10-682560-13; Teeth Missing--Distribution Gear; ATA 7414

A Piper PA-32R arrived at a mechanic’s hangar with a rough running engine. Diagnostics determined one side of the dual magneto was dead. Upon removal and disassembly, this magneto’s defect became clear: multiple teeth were missing from the timing gear. The owner described this particular magneto as “...low time,” but no specific hours were provided. Aircraft total time was given as 2,289.8 hours. (Gear part number not provided. See an example in the next Alert item’s attached photograph.)

Part Total Time:  (unknown).

 

TCM Magneto; 10-500556-1; Teeth Missing--Distributor Gear; ATA 7414

This failed magneto was removed from a Continental O-470 powering a Cessna 182H. Twenty-four teeth were found missing from the distributor gear (P/N 10-357584). New replacement gear (P/N 10-357586) provided new life for this unit. (Time since overhaul is estimated at 678.0 hours. The following photograph nicely depicts ‘dental’ problems with distributor gears.)

Part Total Time:  (unknown).

SUPERIOR AIR PARTS

Superior Air Parts; Engine Through-Bolts; Broken Bolts; ATA 8530

A mechanic states, “12.36 hours after installing (this particular) through-bolt and torquing it to specifications—the bolt broke (P/N SA641931-10.75;  Lot/N B05006996). (This) totals five broken bolts on three different engine models.”  (Unfortunately, the applied torque for a given application was not provided. Original bolt specifications and their comparison to bench-test results of a couple of new and used bolts would have been very telling.


One can increase the “validity” of any concern by describing frequency and method of instrument calibration, and degree of sample control. A necessary condition of validity is “reliability”. Reliability improves for any concern by increasing the number of measures. At what torque values do brand “X” and “Y” fail? How many times out of five tests, does each succeed or fail? Finally, include contact information. Your measures have to be repeatable by others, further increasing “reliability.” Perhaps other mechanics that have experience with these bolts will provide additional detail. See the attached picture.)

Part Total Time:  12.36 hours.

AIR NOTES

ELECTRONIC VERSION OF FAA FORM 8010-4, MALFUNCTION OR DEFECT REPORT

One of the recent improvements to the Flight Standards Service Aviation Information Internet web site is the inclusion of FAA Form 8010-4, Malfunction or Defect Report. This web site is still under construction and further changes will be made; however, the site is now active, usable, and contains a great deal of information.

Various electronic versions of this form have been used in the past; however, this new electronic version is more user friendly and replaces all other versions. You can complete the form online and submit the information electronically. The form is used for all aircraft except certificated air carriers who are provided a different electronic form. The Internet address is: http://forms.faa.gov/forms/faa8010-4.pdf

When the page opens, select “M or D Submission Form” and, when complete, use the “Add Service Difficulty Report” button at the top left to send the form. Many of you have inquired about this service. It is now available, and we encourage everyone to use this format when submitting aviation, service-related information.

 


PAPER COPY OF FAA FORM 8010-4, MALFUNCTION OR DEFECT REPORT

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.

 

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) database 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, Mechanical Reliability Reports (MRRs), 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/ .

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 database 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.
