This Special Airworthiness Information Bulletin (SAIB) advises airplane operators, fixed base operators (FBOs), FAA repair stations, Flight Standards District Offices (FSDOs), and foreign civil aviation authorities of jet fuel supplies for which the concentration of aromatic hydrocarbons and the net heat of combustion may not have been measured in accordance with methods specified by the type certificate (TC) holder. These jet fuel supplies would not be compliant with the FAA approved jet fuel operating limitations and should not be used on the TC holders’ products.
This Special Airworthiness Information Bulletin (SAIB) advises airplane operators, fixed base operators (FBOs), FAA repair stations, Flight Standards District Offices (FSDOs), and foreign civil aviation authorities of certain airplanes that uplifted jet fuel contaminated with diesel exhaust fluid (DEF), or uplifted jet fuel using refueling equipment that was exposed to DEF.
This revised Special Airworthiness Information Bulletin (SAIB) informs owners, operators, repair stations, and flight standard district offices that compliance with a new or revised airworthiness limitation section (ALS) issued by a design approval holder (DAH), or other entity, as a type design change is not mandatory for in-service aircraft operating pursuant to Title 14 of the Code of Federal Regulations (14 CFR) part 91, unless the aircraft owner/operator voluntarily incorporates the change, it is mandated by an airworthiness directive (AD) to resolve an unsafe condition or required by a previously agreed upon maintenance program..
This Special Airworthiness Information Bulletin (SAIB) alerts registered owners, operators, and certified repair facilities of all airplanes equipped with Teledyne Continental Motors (TCM) Model C75, C85, C90, C125, C145, O-200, O-300, and GO-300 series and Rolls-Royce plc (RR) C90, O-200 and O-300 series reciprocating engines of miscommunication regarding the applicability section of AD 94-05-05 R1, effective on February 13, 1996. The FAA has received reports that FAA personnel have provided guidance that has resulted in confusion on complying with AD 94-05-05R1. The intent of this SAIB is to correct this miscommunication.
This Special Airworthiness Information Bulletin (SAIB) is written to announce the availability of an industry and government developed best practice guide (BPG). The BPG is titled: “Best Practices Guide for Maintaining Exhaust System Turbocharger to Tailpipe V-band Couplings/Clamps”.
This Special Airworthiness Information Bulletin addresses issues found in in the installation of F. Atlee Dodge Aircraft Services LLC. folding jump seats in a variety of Textron Aviation, Inc. (Cessna) airplanes following Supplemental Type Certificate (STC) SA02008AK and field approval installations of the same or similar seats.
From the FAA: SUMMARY: We are adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, 414, 414A 421, 421A, 421B, 421C, and 425 airplanes. This AD requires repetitively inspecting the left and the right forward lower carry through spar cap for cracks and replacing the carry through spar if cracks are found. This AD was prompted by a report of a fully cracked lower forward carry through spar cap found on an affected airplane. We are issuing this AD to address the unsafe condition on these products.
This Special Airworthiness Information Bulletin is to provide awareness of an approved alternative method of compliance (AMOC) to all FAA airworthiness directives (ADs) and previously approved AMOCs that mandate the application of Alodine for all FAA type certificated aircraft, engines and propellers. The AMOC allows the use of the renamed Henkel Bonderite products as an alternative to the former Henkel Alodine products when complying with FAA ADs and previously approved AMOCs.
FAA SUMMARY: We are adopting a new airworthiness directive (AD) for certain Aerospace Welding Minneapolis, Inc. mufflers, part numbers A1754001-23 and A1754001-25, installed on airplanes. This AD was prompted by occurrences of cracks or broken welds in the connecting weld of the muffler body to muffler cuff that may allow carbon monoxide exhaust fumes into the cockpit heating system. This AD requires an inspection of the muffler for leaking to identify cracks and replacement of the muffler. We are issuing this AD to address the unsafe condition on these products.
SAIB: CE-18-07 Exhaust Turbocharger; V-band Couplings Used in Exhaust Systems on Turbocharged Reciprocating Engine Powered Aircraft
From the FAA: This Special Airworthiness Information Bulletin alerts owners, operators, maintenance technicians, and inspectors of an airworthiness concern, specifically failure of v-band couplings used in exhaust systems on turbocharged aircraft. Cracks originating out of a spot weld, on multi-segment, spot welded, v-band couplings have led to separation of the outer band and failure of the v-band coupling to retain the tailpipe or exhaust inlet pipe on all turbocharged, reciprocating engine powered aircraft, including rotorcraft.

FAA SUMMARY: This Special Airworthiness Information Bulletin alerts owners, operators, maintenance technicians, and inspectors of an airworthiness concern on Textron Aviation Inc. (Cessna Aircraft Company) Models 172RG, R182, TR182, FR182, and all variants of 210/T210/P210-series airplanes with the exception of the Models 210 and 210A airplanes. The intent is to emphasize the importance of the inspection of main landing gear actuator assemblies following Textron Aviation Inc. supplemental inspection documents (SIDs) applicable to each model to prevent malfunctions related to gear extension and retraction.
FAA SUMMARY: We are adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. Models 402C and 414A airplanes (type certificate previously held by Cessna Aircraft Company). This AD requires inspecting the nacelle fittings for cracks, replacing if necessary, and reporting the results of the inspection to the FAA. This AD was prompted by reports of cracks found on certain nacelle fittings. We are issuing this AD to correct the unsafe condition on these products.
FAA SUMMARY: We are adopting a new airworthiness directive (AD) for NavWorx, Inc. (NavWorx), Automatic Dependent Surveillance Broadcast (ADS-B) Universal Access Transceiver Units (unit). This AD requires removing, disabling, or modifying the ADS-B unit. This AD was prompted by a design change that results in the unit communicating unreliable position information. The actions in this AD are intended to address an unsafe condition on these products.
FAA AD SUMMARY: We are superseding an existing airworthiness directive (AD) for Superior Air Parts and Lycoming Engines fuel-injected reciprocating engines. That AD currently requires removing AVStar Fuel Systems, Inc. (AFS) fuel servos installed after May 20, 2010, if the servo contained an AFS diaphragm, part number (P/N) AV2541801 or P/N AV2541803, from certain production lots. This AD expands the applicability, and changes the compliance interval for all affected Superior Air Parts, Lycoming Engines, and Continental Motors, Inc., fuel-injected reciprocating engines. This AD was prompted by an accident involving a Piper PA32R-301 airplane, and by the discovery of additional engines being affected by the unsafe condition since we issued the existing AD. We are issuing this AD to prevent an in-flight engine shutdown due to a failed fuel servo diaphragm, and damage to the airplane.
