97-26-18: This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA-360C helicopters. This action requires replacement of the main gear box (MGB) input bevel pinion (bevel pinion). This amendment is prompted by service reports of bevel pinion fatigue cracking. This condition, if not corrected, could result in failure of the MGB and a subsequent forced landing.
2004-03-25: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340-200 and -300 series airplanes, that requires repetitive inspections for proper installation of the parachute pins located in the escape slides/rafts at the door 3 Type I emergency exits on the left and right sides of the airplane; a one-time inspection of the associated electrical harnesses for the escape slides/rafts for proper routing and installation; and corrective actions if necessary. This AD also requires adjustment of the speed lacing for the soft covers of the escape slides/rafts, which will terminate the repetitive inspections. This action is necessary to prevent failure of the escape slides/rafts to deploy correctly at door 3 Type I emergency exits, which could result in the escape slides/rafts being unusable during an emergency evacuation, and consequent injury to passengers or crew members. This action is intended to address the identified unsafe condition.
95-24-02: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747SP series airplanes, that requires modification of the escape slide/raft on Door 2 of the airplane. This amendment is prompted by reports indicating that the escape slide/raft on Door 2 deployed onto the wing of the airplane and did not inflate automatically. The actions specified by this AD are intended to ensure that the escape slide/raft on Door 2 inflates automatically so that passengers are able to exit the airplane through Door 2 in the event of an emergency evacuation.
98-17-09: This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A310 and A300-600 series airplanes, that currently requires a revision of the Airplane Flight Manual that warns the flightcrew of certain consequences associated with overriding the autopilot when it is in the pitch control axis. That AD also requires modification of certain flight control computers, and a modification to the autopilot. For certain airplanes, that AD also requires repetitive operational testing of the modified autopilot to determine if the disconnect function operates properly, and repair, if necessary. This amendment adds a new requirement to accomplish those repetitive operational tests on other airplanes. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent an out-of-trim condition between the trimmable horizontal stabilizer and the elevator, which could result in severely reduced controllability of the airplane.
95-22-13: This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires an inspection to determine proper clamping and to detect damage of a wire bundle in the avionics compartment, and repair, if necessary. This amendment is prompted by a report of smoke and fire in the avionics compartment floor area that was caused by electrical arcing that occurred as the result of chafed wiring. The actions specified in this AD are intended to prevent smoke and fire in the avionics compartment due to such electrical arcing in the wire bundle; that condition could pose a hazard to the continued safe flight of the airplane.
2021-05-22: The FAA is adopting a new airworthiness directive (AD) for certain Safran Helicopter Engines, S.A. (Safran Helicopter Engines) Arriel 1B, Arriel 1C, Arriel 1C2, Arriel 1D1, Astazou XIV B, and Astazou XIV H model turboshaft engines. This AD was prompted by the detection of positive segregation (freckles) on Stage 2 high-pressure turbine (HPT) disks and Stage 3 turbine wheels. This AD requires removal from service of certain Stage 2 HPT disks for Safran Helicopter Engines Arriel 1B, 1C, 1C2, and 1D1 model turbofan engines and affected Stage 3 turbine wheels for Safran Helicopter Engines Astazou XIV B and XIV H model turbofan engines. The FAA is issuing this AD to address the unsafe condition on these products.
2004-03-17: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SP, and 747SR series airplanes, that requires a one-time inspection of each emergency evacuation slide or slide/raft to determine if a certain discrepant hose assembly is installed, and replacement of the hose assembly with a new or serviceable assembly if necessary. This action is necessary to prevent the failure of an emergency evacuation slide or slide/raft to fully inflate during an emergency situation, which could impede an evacuation and result in injury to passengers or airplane crewmembers. This action is intended to address the identified unsafe condition.
2010-14-02: 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: Two cases of a crack on a "dry" ADG [air driven generator] (Hamilton Sundstrand part number in the 761339 series), in the aft area of the strut and generator housing assembly, have been reported on CL-600-2B19 aircraft. The same part number is also installed on CL-600-2B16 (CL-604) aircraft. Investigation determined that the crack was in an area of the strut where the wall thickness of the casting was below specification, due to a manufacturing anomaly in a specific batch of ADGs. Structural failure and departure of the ADG during deployment could possibly result in damage to the aircraft structure. If deployment were activated by a dual engine shutdown,ADG structural failure would also result in loss of hydraulics for the flight controls. * * * * * The unsafe condition is possible loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
95-21-17: This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model Hawker 1000 and BAe 125-1000A series airplanes, that requires an inspection to detect damage to an electrical cable loom (wire bundle). This amendment also requires tying back the loom with a cable tie to the cable loom support bracket, and repair, if necessary. This amendment is prompted by a report indicating that damage had occurred to the electrical cable loom. The actions specified by this AD are intended to prevent incorrect fault displays in the cockpit and possible electrical systems failures, as a result of damage to the electrical cable loom.
2021-02-01: The FAA is superseding Airworthiness Directive (AD) 2015-26- 01, which applied to certain Airbus Helicopters Model AS332C1, AS332L1, AS332L2, EC225LP, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters with an energy-absorbing seat. AD 2015-26-01 required inspecting for the presence of labels (placards) that prohibit stowing anything under the seat, and if a label (placard) is missing or not clearly visible to each occupant, installing a label (placard). This AD retains all of the requirements of AD 2015-26-01, and also adds helicopters to the applicability and requires a modification (installing new labels (placards)). This AD was prompted by the determination that additional helicopters are affected by the unsafe condition, and that new labels (placards) are required for all affected helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
