2008-04-02: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires inspecting all barrel nuts to determine if the barrel nuts have a certain marking, inspecting affected bolts to determine if the bolts are pre-loaded correctly, and replacing all hardware if the pre-load is incorrect. For airplanes on which the pre-load is correct, this AD requires doing repetitive visual inspections for cracking of the barrel nuts and cradles and replacing all hardware for all cracked barrel nuts. This AD also requires replacement of all hardware for certain affected barrel nuts that do not have cracking, which would end the repetitive inspections for those airplanes. This AD also provides an optional replacement for all affected barrel nuts. This AD results from reports of cracking in the barrel nuts at the four primary front spar wing-to-fuselage attachment joints. We are issuing this AD to detect and correct cracking of the barrel nuts at the wing front spar wing-to- fuselage joints, which could result in reduced structural integrity of the wing-to-fuselage attachments and consequent detachment of the wing.
2001-14-13: This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 767-200 series airplanes modified by Supplemental Type Certificate ST09022AC-D, that requires modifying the passenger entertainment system (PES) and revising the Airplane Operations Manual. This action is necessary to ensure that the flight crew is able to remove electrical power from the entire PES when necessary and is advised of appropriate procedures for such action. Inability to remove power from the PES during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.
94-19-06: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Puritan Bennett Sweep-On Model 2000 crew masks installed on various transport and commuter category airplanes. This action requires modification of certain crew oxygen masks. This amendment is prompted by reports of difficulty in exhaling into certain crew oxygen masks due to misalignment of the demand diaphragm. The actions specified in this AD are intended to prevent the flight crew from experiencing difficulty in exhaling into the affected crew oxygen masks in the event oxygen masks are required for the crew, such as during depressurization of the airplane.
2008-03-21: 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: * * * * * Recently, it was discovered that the inspection procedure as described by Fokker 50 Non-Destructive Testing Manual (NDTM), Part 6, Chapter 53-30-02, which is referenced by Fokker 50 Maintenance Review Board (MRB) Tasks Number 530000-00-04 and 530000-00-08 [currently required per AD (BLA) 2002-061], did not show the correct inspection areas. In addition to the existing procedure, the area at the kink in the bottom fuselage skin, the actual chine line, must be inspected. Investigation revealed that a number of aircraft have already passed the relevant inspection thresholds of 20,000 and 45,000 flight cycles by a considerable margin. As a result, it may be possible that cracks have developed and remained undetected. * * * * * * * * The unsafe condition is cracking and subsequent failure of the fuselage bottom skin, which could result in reduced structural integrity of the fuselage. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
2017-18-07: We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a discovery of noncompliant rivets in the flight deck upper skin. This AD requires replacement of noncompliant rivets. We are issuing this AD to address the unsafe condition on these products.
2001-14-01: This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 757-200 series airplanes modified by Supplemental Type Certificate (STC) SA1727GL, that requires deactivation of the air-to-ground telephone system approved by that STC. This action is necessary to prevent the inability of the flight crew to remove power from the telephone system when necessary. Inability to remove power from the telephone system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.
2008-03-19: 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: Bombardier Aerospace has completed a system safety review of the CL-600-2B19 aircraft fuel system * * *. The assessment showed that sealant has not been applied to bolts on the collector fuel tanks or the transfer ejector fuel pumps. Lack of sealant on the above-noted locations, if not corrected, could result in arcing and potential ignition source inside the fuel tank during lightning strikes and consequent fuel tank explosion. * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
2001-14-03: This amendment adopts a new airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-10-30 series airplanes modified by Supplemental Type Certificate (STC) ST00054SE, that requires removal of the in-flight entertainment (IFE) system installed by that STC. This action is necessary to prevent inability of the flight crew to remove power from the IFE system when necessary. Inability to remove power from the IFE system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.
2022-13-17: The FAA is superseding Airworthiness Directive (AD) 2021-15-01 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 model turbofan engines. AD 2021-15-01 required revisions to the airworthiness limitations section (ALS) of the Rolls-Royce (RR) Trent XWB time limits manual (TLM) and the operator's existing approved aircraft maintenance program (AMP). Since the FAA issued AD 2021-15-01, the manufacturer has revised the TLM life limits and updated mandatory inspection intervals of certain critical rotating parts. This AD requires revisions to the ALS of the RR Trent XWB TLM and the operator's existing approved AMP, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2020-07-12: The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R(eacute)gional Model ATR42-500 airplanes. This AD was prompted by a report of interference between bonding braid screws and pitch tab control rods on the ATR final assembly line. This AD requires an inspection of the bonding braid screws for proper installation, a detailed inspection for damage to the pitch tab control rods if necessary, and replacement of the pitch tab control rods if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
