2010-09-10: We are superseding an existing 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: AD CF-2002-12 [which corresponds to FAA AD 2003-04-21, amendment 39-13070] mandated installation of revised overwing emergency exit placards showing that the exit door should be opened and disposed from a seated position. However, it was later discovered that the new placards illustrated an incorrect hand position for removal of the exit upper handle cover. These incorrect instructions could cause difficulty or delay when opening the overwing emergency exit. As a result, the timely and safe evacuation of passengers and crew may be impeded. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective June 3, 2010. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 3, 2010. On April 4, 2003 (68 FR 9509, February 28, 2003), the Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD.
2021-04-02: The FAA is superseding Airworthiness Directive (AD) 2020-04- 22, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2020-04-22 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD continues to require the actions in AD 2020-04-22 and also requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
2010-10-24: 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: During the overhaul of a Main Landing Gear (MLG) of a Falcon 2000, the sleeve on the hydraulic flow restrictor in the shock absorber was found displaced, because of the rupture of its three retaining screws. * * * Failure of the retaining screws has been determined to be the final phase of a slow unscrewing process under normal operational conditions. The unsafe condition only exists once the three screws have failed. * * * * * The unsafe condition is failure of three retaining screws of the MLG shock absorber, which could adversely affect the structural integrity of these airplanes. We are issuing this AD to require actions to correct the unsafecondition on these products.
57-08-01: 57-08-01 BELL: Applies to All 47 Series Helicopters With Tail Rotor Drive Shafts, P/N 47-644-115-1, 47-644-126-3, 47-644-172-3, 47-644-177-1, 47-644-179-7, 47-644-180-1, 47-644- 186-1, 47-644-187-1, 47-644-187-5, and 46-644-214-1, Having Less Than 100 Hours Service Time and All Spares of These Part Numbers. Compliance required as indicated. Due to suspected defective materials, the listed tail rotor drive shafts must be inspected for evidence of longitudinal cracks, as follows: 1. Inspect all spare shafts by magnaflux methods immediately. 2. Shafts installed on helicopters and having less than 100 hours service time must be thoroughly cleaned and inspected daily with at least a 10-power magnifying glass, and inspected by magnaflux methods not later than the next 10 flying hours. The daily inspections may be discontinued upon completion of the magnaflux inspection. 3. Spare shafts and helicopters delivered from Bell after April 15, 1957, have these inspections accomplished and may be identified by a double interlocking magnaflux stamp in approximately the centers of the shafts. (This AD covers the same inspections required by CAA telegraphic instructions, dated April 12 and 17, 1957.)
2004-03-03: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Fokker Model F.28 Mark 0070 and 0100 series airplanes. This action requires revising the applicable airplane flight manual to provide the flightcrew with more restrictive procedures for operating in icing conditions. This action is necessary to ensure that the flightcrew is aware of the procedures required to prevent ice from contacting the ice impact panels on the engine fan case. Such contact could result in a panel coming loose during flight and blocking the bypass flow through the engine outlet guide vanes, and consequent reduction of the engine thrust, resulting in insufficient thrust to maintain flight. This action is intended to address the identified unsafe condition.
2021-02-15: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747- 200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, and 747SR series airplanes. This AD was prompted by reports of inboard foreflap departures from the airplane. This AD requires repetitive replacement of certain parts; a general visual inspection to determine production configuration for certain parts; a repetitive lubrication of certain parts and a repetitive general visual inspection of certain parts for any exuding grease; repetitive detailed inspections of certain parts for loose or missing attachment bolts, cracks or bushing migration, cracks or gouges, or broken, binding, or missing rollers; repetitive detailed inspections of certain parts for cracks or corrosion; repetitive lubrication; and on-condition actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
54-22-01: 54-22-01 LOCKHEED: Applies to Models 49, 649, 749, and 1049 Airplanes as Noted in Referenced Service Bulletins. Compliance required by April 1, 1955. A recent engine fire resulted in a premature failure of a flexible hose in the feathering line and in penetration of fire from zone 1 into zone 2. 1. To increase the fire resistance integrity of the propeller feathering line between the pump and the governor, replace the existing flexible hose assemblies meeting current fire resistance requirements. The following Lockheed Service Bulletins cover this subject: No. 49/SB-786 for Model 049 through 749 airplanes and No. 1049/SB-2195 for Model 1049 airplanes. The following hose assemblies may also be considered acceptable for this application: (a) Aeroquip 680-10S hose assemblies with Aeroquip 304 protective sleeves over end fittings. (b) Resistoflex - SSFR-3800-10 hose assemblies. 2. To increase the fireproof integrity of the zone 1 fire seal diaphragm against burn-through into zone 2 in the event of a power section fire install steel plates over the lower engine cowling longerons adjacent to the diaphragm. The following Lockheed Service Bulletins cover this subject: No. 49/SB-760 for Model 649/749 airplanes and No. 1049/SB-2115 for Model 1049 airplanes.
95-15-01: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes equipped with over-wing escape slides, that currently requires modification of the trailing edge panels and the aft flaps. That amendment was prompted by the results of functional tests of over-wing escape slides, which revealed that some slides were damaged when they were deployed across sharp corners on the trailing edge of the wing and the large gaps between the trailing edge panels of the wing. This amendment expands the applicability of the existing AD to include additional airplanes. The actions specified by this AD are intended to prevent damage to the over-wing escape slide, which could hinder inflation of the slide to a usable configuration during an emergency evacuation.
2021-02-17: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319-111, A319-112, A319- 113, A319-114, A319-115, A319-131, A319-132, A319-133, A319-151N, and A319-153N airplanes; Model A320 series airplanes; and Model A321 series airplanes. This AD was prompted by the results of laboratory tests on non-rechargeable lithium batteries installed in emergency locator transmitters (ELT), which highlighted a lack of protection against certain currents that could lead to thermal runaway and a battery fire. This AD requires modifying a certain ELT by installing a diode in the airplane circuit connecting the ELT battery, 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.
2021-01-06: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 and A330-300 series airplanes, and all Model A340-200 and A340-300 series airplanes. This AD was prompted by reports of hydraulic system failure due to fatigue failure of the screws attaching the manual valve to the ground service manifold (GSM). This AD requires, for certain GSMs, repetitive replacement of the hydraulic system GSM manual valve attachment screws having certain part numbers; and, for certain other GSMs with certain screws installed, replacement of those screws, 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.
