Compliance is required within 90 days after the effective date of this AD. To prevent loss of pressurization as a result of conducting the procedures for electrical smoke or fire, accomplish the following, unless previously accomplished. A. Modify the Airplane Flight Manual and notify flight crews as follows. This may be accomplished by inserting a copy of this AD in the Airplane Flight Manual. 1. In Section 3, Page 12A, add: "In the event that the procedure for electrical smoke or fire has to be carried out when both pneumatic and both air conditioning systems are operative, the subsequent busbar switching actions will result in the loss of one air conditioning system. Therefore, reduce aircraft altitude to 25,000 feet or below, as soon as practicable." 2. In Section 3, Page 12A, add: "In the event that the procedure for electrical smoke or fire has to be carried out with either pneumatic or either air conditioning system inoperative, reduce aircraft altitude to 15,000 feet or below, as soon as practicable, and open the ram air valve." 3. In Section 4, Page 49, add: "Should a pneumatic or an air conditioning system fail above 25,000 feet, reduce aircraft altitude to 25,000 feet or below, as soon as practicable." B. The limitation defined in paragraph A.2., above, may be removed after BAe Modification 21-PM5930 to the electrical system is incorporated. C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region. D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of the modifications required by this AD. All persons affected by this directive who have not already received the appropriate service document from the manufacturer may obtain copies upon request to British Aerospace, Inc., Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, D.C. 20041. This document may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification office, 9010 East Marginal Way South, Seattle, Washington. This amendment becomes effective July 6, 1987.
2007-23-07: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: This Airworthiness Directive (AD) results from one report of main landing gear wheel attaching nut partly unscrewed on a TBM 850 what has generated a loss of braking and which could lead to a wheel loss. The investigation revealed that this incident was due to a wheel axle machining issue, concerning a few production batches. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
2022-25-21: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-1041 airplanes. This AD was prompted by a report of a loud noise and vibration in the belly fairing (BF) access panel above the wings. This AD requires a one-time detailed inspection of the BF access panels and, depending on findings, accomplishment of applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
2007-22-08: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the aviation authority for the United Kingdom to identify and correct an unsafe condition on an aviation product. The MCAI states the following: This action is necessary following the discovery of IP Compressor Rotor stage 2-3 interstage spacer cracking on an in- service Trent 700 engine. Stress analysis of the damaged rotor has shown a possible threat to the rotor integrity, the cracking therefore presents a potential unsafe condition. The cause of the cracking is currently under investigation. We are issuing this AD to detect cracks in the stage 2-3 interstage spacer of the intermediate pressure (IP) Compressor Rotor. Cracking of the stage 2-3 interstage spacer could result in an uncontained engine failure and damage to the airplane.
2022-26-03: The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW169 helicopters.
