51-03-02: 51-03-02 MARTIN: Applies to All Models 202 and 202A Aircraft. Compliance required by April 1, 1951, on all aircraft having main landing gears with 4,000 hours service or more, and thereafter every 4,360 cycles of landing gear operation. Due to reported occurrences of cracks, the main landing gear crankshafts (P/N 202SD82019 and 202SD82021) should be replaced with new crankshafts bearing the same part numbers and having a ground radius around the periphery of the hole for the retract pin. (Martin Service Bulletin No. 128, dated October 4, 1950, covers this same subject.)
2006-04-14: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. This AD requires installing clamps on certain end caps of the overhead distribution ducts, and doing other specified and related investigative actions as necessary. This AD results from finding that the end caps of the overhead distribution ducts for the air conditioning system were not bonded to the ducts with an adhesive. We are issuing this AD to detect and correct loosened end caps, which could change the air flow balance in the airplane. During a smoke event in the cargo or main electronics compartment, the incorrect balance of air flow could change the smoke clearance air capacity and result in smoke and toxic fumes penetrating the flight deck and main cabin.
98-18-04: This amendment adopts a new airworthiness directive (AD), applicable to all Aerospatiale Model SN-601 (Corvette) series airplanes, that requires repetitive inspections to detect corrosion, cracking, or rupture of the support arms of the aileron balance weights; and repair, if necessary. Accomplishment of the repair terminates the repetitive inspection requirement of this AD. 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 corrosion, cracking, or rupture of the support arms of the aileron balance weights, which may cause reduced flutter damping or jamming of the aileron, and consequent reduced controllability of the airplane.
95-19-08 R1: This amendment revises an existing airworthiness directive (AD), applicable to certain Boeing Model 727-100 and -200 series airplanes, that currently requires replacing the attaching nutplates on certain engine nose cowls with washers and self-locking nuts. This amendment changes the responsible office for approval of an alternative method of compliance. This amendment is prompted by the transfer of the supplemental type certificate. The actions specified in this AD are intended to prevent the attach bolts from becoming loose, which could result in subsequent separation of the nose cowl from the engine.
83-23-01: 83-23-01 PILATUS BRITTEN-NORMAN LTD: Amendment 39-4764. Applies to Models BN-2, BN-2A and BN-2B Islander Series Airplanes equipped with wing tip tanks (Mod NB/M/364) certificated in any category except BN-2A MKIII Series Trislander Airplanes. Compliance: Required within 100 hours time-in-service after the effective date of this AD, but no later than December 31, 1983, unless already accomplished. To preclude fuel mismanagement and possible fuel starvation, accomplish the following: a) Modify the wing tip tank fuel management system in accordance with steps 1. through 12. of the ACTION section of Pilatus Britten-Norman Ltd. Service Bulletin No. BN- 2/SB.157, dated March 14, 1983. 1) Upon completion of the modification described in paragraph a) update and annotate the appropriate airplane flight manual as follows: i) BN-2A-3 Model: insert Issue 4 of Supplement No. 8 to Section 7 of Flight Manual FM/10 dated March 4, 1983; ii) BN-2A-9 Model: insert Issue 2 of Supplement No. 16 to Section 7 of Flight Manual FM/2 dated March 4, 1983; iii) BN-2A-21 Model: insert Issue 4 of Supplement No. 8 to Section 7 of Flight Manual FM/10 dated March 4, 1983; iv) BN-2A-27 Model: insert Issue 2 of Supplement No. 1 to Section 7 of Flight Manual FM/20 dated March 4, 1983; v) BN-2B-21 Model: insert Issue 3 of Supplement No. 1 to Section 7 of Flight Manual FM/43 dated March 4, 1983; vi) BN-2B-27 Model: insert Issue 5 of Supplement No. 1 to Section 7 of Flight Manual FM/42 dated March 4, 1983. NOTE: The requirement for insertion of specific revisions in the affected Airplane Flight Manuals does not prohibit incorporation of later revisions containing the same information. 2) The requirement of paragraph a)1) of this AD may be accomplished by the holder of a pilot certificate issued under Part 61 of the Federal Aviation Regulations (FAR) on any airplane owned or operated by him. The person accomplishing this action must make the appropriate aircraft maintenance record entry as prescribed by FAR 91.173. b) Aircraft may be flown in accordance with FAR 21.197 to a location where this AD can be accomplished. c) An equivalent method of compliance with this AD, if used, must be approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, 1000 Brussels, Belgium. This amendment becomes effective on December 8, 1983.
2015-19-12: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This AD was prompted by reports that six fasteners may not have been installed in the left and right stringer 37 (S-37) between body stations (BS) 428 and 431 lap splices on certain airplanes. This AD requires a general visual inspection of S-37 lap splices for missing fasteners, and all applicable related investigative and corrective actions. We are issuing this AD to detect and correct missing fasteners, which could result in cracks in the fuselage skin that could adversely affect the structural integrity of the airplane.
2010-20-10: The FAA is superseding an existing airworthiness directive (AD), which applies to all Model 750 airplanes. That AD currently requires inspecting the inboard-hinge brackets of the left and right elevators for cracking and doing related investigative and corrective actions if necessary. For certain airplanes, this new AD requires inspecting for cracks of the bracket of the inboard horizontal stabilizer and measuring the lug thickness of the horizontal stabilizer hinges; doing corrective actions if necessary; and modifying the left and right elevators and left and right horizontal stabilizer. For all airplanes, this new AD requires replacing the existing elevator assemblies with new elevator assemblies, which terminates the requirements of the existing AD. This new AD also revises the applicability to remove certain airplanes. This AD results from a report of cracking found on the elevator inboard-hinge brackets and the horizontal stabilizer hinges. We are issuing this AD to prevent such cracking of the elevator inboard-hinge brackets and the horizontal stabilizer hinges, which could result in structural failure of the elevators and consequent loss of control of the airplane.
2015-19-13: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of inadvertent deployment of a single outboard spoiler during flight. This AD requires replacement of the power control units (PCUs) for the outboard spoilers with upgraded PCUs. We are issuing this AD to prevent leakage of the piston head seal and piston rod seals of the outboard spoiler PCUs, which could result in inadvertent spoiler deployment and reduced controllability of the airplane.
2010-19-01: The FAA is superseding an existing airworthiness directive (AD) for RRC AE 3007A series turbofan engines. That AD currently requires performing an eddy current inspection (ECI) or surface wave ultrasonic test (SWUT) inspection on each affected high-pressure turbine (HPT) wheel. This AD requires removing or performing initial and repetitive ECIs or SWUT inspections on HPT stage 2 wheels for cracks. This AD also reduces the approved life limits of certain HPT stage 2 wheels. This AD results from reports of cracked HPT stage 2 wheels. We are issuing this AD to prevent uncontained failure of the HPT stage 2 wheel and damage to the airplane.
2000-15-02: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747-400 series airplanes. This action requires a one-time inspection to determine if certain wire bundles are routed incorrectly and to detect damage, and corrective actions, if necessary. This action is necessary to prevent damage of certain wire bundles routed to the fuel tank transfer pumps in the horizontal stabilizer, which could result in electrical arcing and a possible fire adjacent to the fuel tank. This action is intended to address the identified unsafe condition.
