            FAA recommend that owners, operators, and maintenance technicians and inspectors visually inspect and confirm their findings using eddy current on the affected Cessna models utilizing aft fin attachment fitting, part numbers 0431009-1/-2/-3, for cracks and corrosion. This should be done repetitively at  100 hours  intervals following inspection procedures described in the applicable Cessna SID located in the table of SIDs. Note that it may be beneficial for the inspection to be accomplished in conjunction with compliance to AD 80-11-04.          FAA and Textron Aviation (Cessna) have been aware of cracking of the aft fin attachment fitting; and have previously issued a number of airworthiness publications to inform owner, operators, and maintenance technicians and inspectors. Cessna issued Service Bulletins (SE74-10 and SE78-62) in addition to the specific inspections noted in the referenced SID. Additionally,...

Mode ‘C’ and Mode ‘S’ transponders, all types and models utilising Gilham code altitude input.                       During the 1990’s, the FAA received reports of eleven incidents involving certain transport category airplanes equipped with Mode "C" transponder(s) with single Gilham code altitude input. These reports indicated that, during level flight, the TCAS II issued false advisories that directed the flight crew to either climb or descend. Further investigation showed that these events were caused by incorrect Gilham coded altitude input. The instances reported in the USA all involved communication between aeroplanes with the TCAS II and aeroplanes having the Mode "C" transponder(s). Aeroplanes having Mode "C" transponders installed are predominantly older, out-of-production transport category (JAR/FAR/CS 25) aeroplanes. Such inaccurate altitude reporting and consequent false TCAS II advisories, if not prevented, could ca...

Subject - Oxygen – Flight Crew Oxygen Mask Regulator – Identification / Operational Procedure / Replacement Applicability - Flight crew oxygen mask regulators, having Part Number (P/N) MC10, MF10 and MF20 series, with serial numbers (s/n) as listed in Appendix 1 of this AD. The affected flight crew oxygen masks regulators are known to be installed on, but not limited to, aeroplanes manufactured by Airbus, ATR, Boeing, Bombardier (formerly Canadair, De Havilland Canada), Cessna, Gulfstream and McDonnell Douglas. Reason In a repair station, improper maintenance on oxygen mask regulators was reported to Intertechnique: during an inspection of the oxygen test bench by its manufacturer, incorrect settings were noticed. This test bench setting discrepancy on the oxygen mask regulator could cause an improper mask dilution schedule.            This condition, if not detected and corrected, could lead, in case of a diversion above 10 000 feet after...
