2006-06-16: The FAA is adopting a new airworthiness directive (AD) for certain Lycoming Engines (formerly Textron Lycoming) AEIO-360, IO-360, O-360, LIO-360, and LO-360 series reciprocating engines. This AD requires replacing certain crankshafts. This AD results from a crankshaft failure in a Lycoming LO-360-A1H6 reciprocating engine. We are issuing this AD to prevent failure of the crankshaft, which could result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.

2009-18-03: We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
Findings of corrosion, wear and cracks in the upper wing strut fittings on some PC-6 aircraft have been reported in the past. It is possible that the spherical bearing of the wing strut fittings installed in the underwing can be loose in the fitting or cannot rotate because of corrosion. In this condition, the joint cannot function as designed and fatigue cracks may then develop. Undetected cracks, wear and/or corrosion in this area could cause failure of the upper attachment fitting, leading to failure of the wing structure and subsequent loss of control of the aircraft.
We are issuing this AD to require actions to correct the unsafe conditionon these products.

99-17-16: This amendment adopts a new airworthiness directive (AD), applicable to Pratt & Whitney (PW) PW4000 series turbofan engines, that requires short term criteria for limiting the number of engines with potentially reduced stability on each airplane to no more than one engine, would require initial and repetitive on-wing or test cell cold-engine high pressure compressor (HPC) stability tests, would require removal of engines from service that fail on-wing test acceptance criteria, and would allow a follow-on test cell stability test. The AD also establishes required intervals for stability testing of the remaining engine with potentially reduced stability on the airplane and requirements for reporting test data. This amendment is prompted by a report of a dual-engine HPC surge event and reports of single-engine HPC surge events during the takeoff and climb phases of flight. The actions specified by this AD are intended to prevent an HPC surge event, which could result in enginepower loss at a critical phase of flight such as takeoff or climb. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of September 24, 1999.

2020-04-10: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter, A330-200, A330-300, A340-200, and A340-300 series airplanes. This AD was prompted by reports that elevator skin panels were found disbonded as a result of water ingress. This AD requires repetitive detailed inspections of skin panels on both elevators, and corrective actions 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.

60-10-07: 60-10-07 MARTIN: Amdt. 141 Part 507 Federal Register May 4, 1960. Applies to All Models 202, 202A and 404 Airplanes.
Compliance required as indicated.
Fatigue failures have occurred on the upper nose gear torque arm, P/N 511653. These failures were approximately 3 inches aft of the safety pin, P/N AN 416-1, which connects the lower torque arm, P/N 511650, to the upper torque arm. As a result of investigation of these failures, the following shall be accomplished prior to June 1, 1960:
(a) Unless already accomplished, rework torque arms, P/N's 511650 and 511653, by increasing the 0.125-inch radius, where the arm tapers to the narrow section at the aft end, to 0.25 inch.
(b) Visually inspect for cracks, using a 10-power magnifying glass or equivalent, the areas on the nose landing gear upper and lower torque arms at all radii near the apex of each torque arm. If crack indications are found, reinspect the above area using dye penetrant or equivalent. Torque armswith cracks must be replaced prior to further flight.
(c) Visually inspect for and remove any nicks or dents in the radius described in (a).
(d) Inspect the scissor disconnect bolt safety pin, P/N AN 416-1, for proper overhang to prevent opening. Safety pins with less than 1/4-inch overhang shall be replaced prior to further flight.
(e) Repeat inspections (b) and (c) at intervals not to exceed 320 hours' time in service and inspection (d) at each safety pin installation.

2006-06-07: The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires inspecting the main landing gear (MLG) main fitting for cracks, and repair if necessary. This AD also requires installing a placard and revising the airplane flight manual to include procedures to prohibit the application of brakes during backward movement of the airplane. This AD results from a report that an MLG main fitting failed on an airplane that was braking while moving backward. We are issuing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.

2019-25-20: The FAA is adopting a new airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes, type certificated in any category; and Model C-130A, C-130B, C-130BL, C-130E, C-130H, C-130H-30, C-130J, C-130J-30, EC-130Q, HC-130H, KC-130H, NC-130B, NC-130, and WC- 130H airplanes, type certificated in the restricted or amateur category. This AD was prompted by a report indicating that two elevator booster assemblies experienced significant hydraulic fluid leaks, caused by fatigue cracks in the actuator cylinder. This AD requires an inspection to determine the part number of the elevator booster actuator, repetitive ultrasonic inspections of the actuator to detect cracking, and replacement of cracked elevator booster assemblies. The FAA is issuing this AD to address the unsafe condition on these products.

99-17-13: This amendment adopts a new airworthiness directive (AD), applicable to certain Lockheed Model L-1011-385 series airplanes, that requires repetitive inspections to detect discrepancies of the lower actuator pins and/or bushings of the horizontal stabilizer, and replacement of any discrepant component with a new component. Replacement of all four actuator pins and bushings terminates the repetitive inspections. This amendment is prompted by a report indicating that a fractured lower actuator pin of the horizontal stabilizer was detected. The actions specified by this AD are intended to detect and correct discrepancies of the lower actuator pins and bushings of the horizontal stabilizer, which could result in reduced structural integrity of the horizontal stabilizer control system, and consequent reduced controllability of the airplane.
