2011-22-04: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: [T]he FAA has published SFAR 88 (Special Federal Aviation Regulation 88). In their letters referenced 04/00/02/07/01-L296, dated March 4th, 2002, and 04/00/02/07/03-L024, dated February 3rd, 2003, the [Joint Aviation Authorities] JAA recommended the application of a similar regulation to the National Aviation Authorities (NAA). Under this regulation, all holders of type certificates for passenger transport aircraft with either a passenger capacity of 30 or more, or a payload capacity of 3,402 kg (7,500 lb) or more which have received their certification since January 1st, 1958, are required to conduct a design review against explosion risks. ** * * * The unsafe condition is insufficient electrical bonding of the over- wing refueling cap adapter, which could result in a possible fuel ignition source in the fuel tanks. We are issuing this AD to require actions to correct the unsafe condition on these products.
2004-08-17: The FAA is adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes.

2004-08-15: The FAA supersedes Airworthiness Directive (AD) 2003-13-08, which currently applies to all Goodrich Avionics Systems, Inc. (Goodrich) TAWS8000 terrain awareness warning systems (TAWS) that are installed on airplanes. AD 2003-13-08 currently requires you to inspect the TAWS installation and remove any TAWS where both the TAWS and any other device are connected to the same baro set potentiometer. AD 2003- 13-08 also prohibits future installation of any TAWS8000 TAWS that incorporates hardware "Mod None", "Mod A", or "Mod B". This AD is the result of omitting from AD 2003-13-08 a provision that prohibits reconfiguring an installed TAWS8000 TAWS after it passes the inspection unless it incorporates hardware "Mod C". This AD retains the actions of AD 2003-13-08 and prohibits future installation or reconfiguration of any TAWS8000 TAWS that does not incorporate hardware "Mod C". We are issuing this AD to prevent the loading of the baro set potentiometer, which could result in an unacceptable altitude error. That condition could cause the pilot to make flight decisions that put the airplane in unsafe flight conditions. DATES: This AD becomes effective on June 7, 2004. On July 21, 2003 (68 FR 38586, June 30, 2003), the Director of the Federal Register approved the incorporation by reference of Goodrich Avionics Systems, Inc. Service Memo SM 134, dated May 2, 2003. As of June 7, 2004, the Director of the Federal Register approved the incorporation by reference of Goodrich Avionics Systems, Inc. Service Memo SM 134, revised July 9, 2003; and Goodrich Avionics Systems, Inc. Alert Service Bulletin SB A117, dated July 9, 2003.
2011-14-02: The FAA is superseding an existing airworthiness directive (AD) that applies to all Model 767 airplanes. The existing AD currently requires repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking, and corrective actions if necessary. This AD expands the inspection area to include the vertical inner chord at STA 1809.5. This AD results from reported fatigue cracking in the vertical inner chord and the forward outer chord while doing the detailed inspection of the horizontal inner chord at STA 1809.5. We are issuing this AD to detect and correct fatigue cracking in the bulkhead structure at STA 1809.5 and the vertical inner chord at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane.
2021-17-04: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A321-211, -231, and -232 airplanes.
