59-20-02: 59-20-02 LOCKHEED: Applies to All Model 1649A Aircraft. Compliance required on items (1) and (2) by October 15, 1959; compliance required on item (3) by December 1, 1959. As a result of a recent accident involving a suspected explosion of a wing tank, the following shall be accomplished to prevent the possible recurrence of such an explosion: (1) Remove the static wick on the inboard wings adjacent to the tank vents. (2) Install temporary placard at engineer's station reading as follows: "In order to maintain a nonexplosive rich mixture in tanks, do not use fuel out of auxiliary tanks Nos. 5, 6, and 7 below 50 gallons. In operations which involve use of fuel from main tanks only, the 50 gallons of residual fuel in the auxiliary tanks must be replaced with 50 gallons of fresh fuel or mixed with at least 150 gallons of fresh fuel at the end of every 12 flight-hours or 5 flights, whichever occurs first." (3) Install P/N 634014-1 or equivalent flame arrestors in the tank vent outlets. After installation of flame arrestors described in item (3), item (2) may be disregarded.
2004-09-12: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 and Model 328-300 series airplanes, that requires repetitive detailed inspections of all attach caps of the passenger seats for cracks or defects; and replacement of the caps with new caps, if necessary. This action is necessary to prevent failure due to cracking of the seat frame attach caps on the passenger seat assemblies, which could result in separation of the passenger seat from the supporting structure during an emergency landing, hard landing, or turbulence, and consequent injury to the seat occupant. This action is intended to address the identified unsafe condition.
2021-17-14: The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes. This AD was prompted by a report that during full-scale fatigue testing, a crack was found in the area of the attachment of the wing rib 0 to the front spar. This AD requires non-destructive testing on the forward (front) spar vertical stiffener and rib 0 for any cracking, installation of a doubler to the forward (front) spar and rib 0 attachment, and repair if necessary, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
71-17-09: 71-17-09 SCHWEIZER AIRCRAFT: Amdt. 39-1272. Applies to SGS 1-23H. Type Gliders. To prevent severe oscillations and vibrations resulting from excessively loose rudder fittings accomplish the following: (a) Within the next 25 hours time in service unless accomplished within the last 75 hours time in service and thereafter at intervals not to exceed 100 hours time in service, inspect the lower and upper rudder and fin hinges P/N 1A-107-2, P/N 23H704-16 & -17, P/N 1A-105-2 and P/N 23H705-21, to assure that neither the fore and aft nor the sidewards free-play exceeds five-thousandths (0.005) inches. (b) If free-play in excess of the limits set forth in paragraph (a) is found, replace hinges and their connecting bolts with parts of the same part number or with FAA approved equivalent parts; or incorporate a modification described in Schweizer Aircraft Corporation Service Bulletin No. 102-23-2 dated 29 June 1971 or an FAA approved equivalent modification. Equivalent partsor modifications must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region. (c) The compliance times may be increased by the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region upon receipt of substantiating data submitted through an FAA Maintenance Inspector. This amendment becomes effective August 26, 1971.
98-11-20: This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45 airplanes that incorporate an executive cabin layout. This AD requires modifying the lavatory wall and passenger seat configuration. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to prevent head injuries during an airplane crash because the lavatory wall and passenger seat configuration do not meet current head injury criteria regulations.
2004-09-01: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B4-600, B4-600R, C4 605R Variant F, and F4-600R (collectively called A300-600) series airplanes; and Model A310 series airplanes. This action requires a one-time inspection for damage of the integrated drive generator electrical harness and pyramid arm, and repair if necessary. This action is necessary to prevent electrical arcing within the engine pylon, which could result in loss of the relevant alternating current (AC) bus bar, reduced structural integrity of the engine pylon, and consequent loss of control of the airplane. This action is intended to address the identified unsafe condition.
98-11-12: This amendment adopts a new airworthiness directive (AD), applicable to certain de Havilland Model DHC-8-301, -311, -314, and -315 series airplanes, that requires installation of additional wiring and new electrical connectors for the lights in the forward end of the passenger overhead compartments. 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 severe overheating of the electrical connectors for the lights in the forward end of the passenger overhead compartments, which could result in smoke and fire in the passenger cabin.
2021-18-09: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This AD was prompted by a report that an operator found solid rivets with missing heads at the left buttock line 25 on the sloping pressure deck web.
