2006-24-09: We are adopting a new 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 a discrepancy between the design documentation and the Technical Service Manual. In 1981, a castellated nut with cotter pin was introduced to secure the rudder, replacing the self-locking nut through PZL-Bielsko Bulletin No. BE-06/50-3/81. This change has not been introduced to the Technical Service Manual and use of a self-locking nut, in accordance with the Manual, is still possible. We are issuing this AD to require actions that are intended to address the unsafe condition described in the MCAI.

80-17-09: 80-17-09 BELL: Amendment 39-3876. Applies to Models 204B, 205A-1, 212, 214B, and 214B-1 helicopters and military UH-1 series helicopters certified in all categories.
Compliance required as indicated for helicopters equipped with main rotor straps, P/N 204-012-122-1, -5, or 214-010-179-1.
To preclude possible separation of a main rotor blade tension-torsion strap and loss of a main rotor blade, accomplish the following:
a. Within the next 100 hours' time in service after the effective date of this airworthiness directive (AD), remove and replace main rotor straps having:
(1) 1,100 or more hours of total time in service on the effective date of this AD, or
(2) 24 or more months elapsed calendar time in service as of the effective date of this AD, whichever comes first.
b. Remove and replace main rotor straps having less than 1,100 hours' total time in service or having less than 24 months elapsed time in service on the effective date of this AD:(1) Prior to attaining 1,200 hours' total time in service, or
(2) Prior to exceeding 24 months elapsed time in service, whichever comes first.
c. The helicopter may be flown in accordance with FAR's 21.197 and 21.199 to a base where this AD may be accomplished.
(Bell Helicopter Textron Alert Service Bulletin No. 212-80-17 pertains to this subject.)
This amendment becomes effective September 15, 1980.

2019-11-09: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-113 and -114 airplanes, and Model A320-211 and - 212 airplanes. This AD was prompted by a report that a life-limit of 64,000 flight cycles has been established for certain titanium crossbeams of the forward engine mount. This AD requires repetitive replacements of all affected crossbeams of the forward engine mount, as specified in European Aviation Safety Agency (EASA) ADs, which are incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

2006-22-15: The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 747 series airplanes. That AD currently requires repetitive inspections for cracking of the top and side panel webs and panel stiffeners of the nose wheel well (NWW), and corrective actions if necessary. This new AD reduces the interval for certain repetitive inspections and removes a certain optional inspection. This new AD also requires replacing the NWW side and top panels with new panels, which terminates the repetitive inspections. This AD results from the development of a new modification. We are issuing this AD to prevent fatigue cracks in the top and side panel webs and stiffeners of the NWW, which could compromise the structural integrity of the NWW and could lead to the rapid decompression of the airplane. \n\nDATES: This AD becomes effective December 11, 2006. \n\n\tThe Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 11, 2006. \n\n\tOn May 10, 2005 (70 FR 21141, April 25, 2005), the Director of the Federal Register approved the incorporation by reference of Boeing Alert Service Bulletin 747-53A2465, Revision 4, dated February 24, 2005.

96-10-01: This amendment adopts a new airworthiness directive (AD) that applies to certain The New Piper Aircraft, Inc. (Piper) Models PA-28-140, PA-28-150, PA-28-160, and PA-28-180 airplanes. This action requires a complete landing light support replacement. This AD action is prompted by reports of two accidents and two incidents resulting from the landing light retainer support seal breaking apart and entering the carburetor. The actions specified by this AD are intended to prevent the landing light retainer support seal from being ingested by the updraft carburetor, which, if not detected and corrected, could result in rough engine operation or possible engine failure and loss of control of the airplane.

2019-10-06: We are adopting a new airworthiness directive (AD) for certain Aviat Aircraft Inc. Models A-1C-180 and A-1C-200 airplanes equipped with a Rapco part number RA1798-00-1 fuel vent check valve installed on either wing or both. This AD was prompted by a report that the fuel tank vent check valves are sticking in the closed position causing fuel starvation to the engine. This AD requires revision of the airplane flight manual (AFM) to add a pre-flight check of the fuel vent check valves for proper operation and replacing any inoperative fuel vent check valve with an airworthy part. We are issuing this AD to address the unsafe condition on these products.

2019-11-08: The FAA is adopting a new airworthiness directive (AD) for all International Aero Engines, LLC (IAE) PW1133G-JM, PW1133GA-JM, PW1130G- JM, PW1129G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM model turbofan engines. This AD requires the removal of the main gearbox (MGB) assembly and electronic engine control (EEC) software and the installation of a part and software version eligible for installation. This AD was prompted by multiple reports of in-flight engine shutdowns (IFSDs) as the result of high- cycle fatigue causing fracture of certain parts of the MGB assembly. The FAA is issuing this AD to address the unsafe condition on these products.

2006-25-05: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This AD requires repetitive inspections for corrosion or missing corrosion inhibiting compound of the fuselage skin under the forward and aft wing-to-body fairings for certain airplanes, or the fuselage skin under the forward wing-to-body fairings only for other airplanes; and corrective action if necessary. The AD also provides an optional preventive modification of the fairing areas, which terminates the repetitive inspections. This AD results from several reports indicating that significant levels of corrosion were found on the external surface of the fuselage skin under the forward and aft wing-to-body fairings. We are issuing this AD to detect and correct corrosion, and prevent subsequent fatigue cracks, on the fuselage skin under the forward and aft wing-to-body fairings, which could result in rapid decompression of the airplane.

2006-25-01: The FAA is superseding an existing airworthiness directive (AD) for certain IAE V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M- A5, V2530-A5, and V2533-A5 turbofan engines. That AD currently requires initial and repetitive inspections of the master magnetic chip detector (MCD) or the No. 1, 2, 3 bearing chamber MCD. This AD requires the same MCD inspections. This AD also requires removing certain No. 3 bearings and removing certain high pressure compressure (HPC) stubshaft assemblies as mandatory terminating actions to the repetitive MCD inspections. This AD results from IAE developing a terminating action to the repetitive inspections of the chip detectors, and from expanding the applicability to include additional serial-numbered engines with certain No. 3 bearings installed. We are issuing this AD to prevent failure of the No. 3 bearing, which could result in an in-flight shutdown (IFSD) and smoke in the cockpit and cabin.

2019-11-07: The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-524G2-19, RB211-524G2-T-19, RB211-524G3-19, RB211-524G3-T-19, RB211-524H2-19, RB211-524H2-T-19, RB211-524H-36 and RB211-524H-T-36 engines. This AD requires removal of affected low- pressure compressor (LPC) shafts. This AD was prompted by unauthorized repairs to the affected LPC shafts that reduced their expected life. The FAA is issuing this AD to address the unsafe condition on these products.
