2007-15-07: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This AD requires repetitive high frequency eddy current inspections for cracks of the fuselage skin at stringer 5 left and right between stations 340 and 350, and corrective actions if necessary. This AD results from reports of fatigue cracks in the fuselage skin near stringer 5 between stations 340 and 350. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin near stringer 5. Cracks in this area could join together and result in in-flight depressurization of the airplane.
77-21-03: 77-21-03 PIPER: Amendment 39-3056. Applies to Model PA-36-285, Serial Nos. 36-7360001 through 36-7760003 certificated in all categories. To prevent hazards in flight associated with rudder spar cracks, accomplish the following: (a) Within the next 50 hours in service from the effective date of this AD unless previously accomplished within the past 50 hours in service and at intervals not to exceed 100 hours in service from the last inspection, inspect the rudder spar at hinge attachment points for cracks using a magnifying glass of at least ten power. (b) If cracks exist replace the rudder assembly with a new rudder assembly Piper Part No. 98125-04 or equivalent. (c) Upon the incorporation of rudder assembly, Piper Part No. 98125-04 or equivalent, compliance with the requirements of this AD may be dispensed with. (d) Equivalent inspection and repairs must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region. (e) Upon submission of substantiating data by an owner or operator through an FAA Maintenance Inspector, the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region may adjust the inspection intervals specified in this AD. (Piper Service Bulletin No. 518 refers to this subject.) This amendment is effective October 18, 1977.
2001-04-08: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, -800, and -700C series airplanes. This action requires initial and repetitive inspections of the elevator tab assembly to detect any damage or discrepancy; and corrective actions, if necessary. This action is necessary to prevent excessive in-flight vibrations of the elevator tab, which could lead to loss of the elevator tab and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2019-16-15: The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW1519G, PW1521G, PW1521GA, PW1524G, PW1525G, PW1521G-3, PW1524G-3, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A model turbofan engines. This AD was prompted by corrosion found on the high-pressure compressor (HPC) front hub, which could result in certain HPC front hubs cracking before reaching their published life limit. This AD requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) and air carrier's approved Continued Airworthiness Maintenance Programs (CAMP) to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
2018-05-08: We are superseding Airworthiness Directive (AD) 2013-19-12 for GA 8 Airvan (Pty) Ltd Models GA8 and GA8-TC320 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the fuel system integral sump tank not meeting FAA regulations. We are issuing this AD to require actions to address the unsafe condition on these products.
2007-15-04: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 737-800 series airplanes. The existing AD currently requires inspecting flight spoilers to determine spoiler position after every landing and after any rejected takeoff maneuver. For airplanes on which any flight spoiler is found in the up position with the speedbrake handle in the down position, the existing AD requires replacing the flight spoiler actuator with a flight spoiler actuator having a certain part number. The existing AD also requires an operational test of the speedbrake control system after any maintenance actions that operate the spoiler system, and replacement of the flight spoiler actuator if necessary. The existing AD also provides for optional terminating action for those requirements. This new AD requires the previously optional terminating action. This AD results from a report of seven flight spoiler actuator jams on Model 737-800 airplanes equipped for short field performance (SFP). The cause of the failure has been identified as interference within the actuator main control valve. We are issuing this AD to prevent operation with defective flight spoiler actuators, which could result in a flight spoiler actuator hardover, and could cause the flight spoiler surface to jam in the fully extended position. Two or more hardover failures of the flight spoiler surfaces in the up direction on the same wing, if undetected prior to takeoff, can cause significant roll and consequent loss of control of the airplane. \n\nDATES: This AD becomes effective August 8, 2007. \n\n\tThe Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 8, 2007. \n\tOn May 7, 2007 (72 FR 21083, April 30, 2007), the Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD. \n\n\tWe must receive any comments on this AD by September 24, 2007.
2009-22-05: 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: There have been several cases of wing leading edge anti-ice piccolo duct failure reported on CL-600-2B19 (CRJ) aircraft. Upon investigation, it was determined that ducts manufactured since May 2000 are susceptible to cracking due to the process used to drill holes in the ducts. This cracking may cause air leakage, with a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability, without annunciation to the flight crew [and consequent reduced controllability of the airplane]. * * * * * It has subsequently been determined that faulty ducts may also have been installed in a number of leading edge assemblies built as spares and whose current locations are not specifically known. * * * * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
2001-04-10: This amendment adopts a new airworthiness directive (AD), applicable to Pratt & Whitney Canada (PWC) Models PW305 and PW305A turbofan engines, that requires removing stage 4 low pressure turbine (LPT) disks from service before exceeding new, lower cyclic life limits. This amendment is prompted by the results of a spin pit test analysis which indicate that the stage 4 LPT disk does not have full published life. The actions specified by this AD are intended to prevent LPT disk failure resulting from premature cracking of the LPT disks, which could result in an uncontained engine failure and damage to the airplane.

2019-16-03: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report of a front engine mount primary pin which moved axially out of place; investigation revealed that incorrect washers had been installed on the engine mount pins. This AD requires a one-time inspection of the washers installed on the front and rear engine mount primary pins and thrust link pins of both engines, depending on configuration, 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.
2010-05-09: 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 number of propeller blade outer sleeves have been found with cracks since 1996. Testing has shown that blade retention integrity is not affected by this cracking. However, this condition, if not detected and corrected, can lead to blade counterweight release, possibly resulting in damage to the aircraft and injury to occupants or persons on the ground. We are issuing this AD to prevent blade counterweight release, which could result in injury or damage to the airplane.
2007-15-01: 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: In-service reports have been received by BAE of failed bolts fitted to frame 199 wing spigot post assembly. If left uncorrected failure of these bolts will severely compromise the structural integrity of the wing to fuselage attachment. Failure of which would lead to loss of the aircraft. We are issuing this AD to require actions to correct the unsafe condition on these products.
2018-05-07: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 and 787-9 airplanes. This AD was prompted by a flight test report indicating that the crew oxygen masks in the flight deck did not deploy correctly. This AD requires an inspection at four locations in the flight deck to determine whether any crew oxygen mask having a certain part number is installed, and replacement of affected crew oxygen masks. We are issuing this AD to address the unsafe condition on these products.
96-20-09: This amendment adopts a new airworthiness directive (AD), applicable to all Jetstream Model HS 748 series airplanes. This action requires a one-time inspection to ensure proper operation, positioning, and lubrication of the aileron, rudder, and elevator cable tensioners; gust lock levers; and cable pressure seals. It also requires a revision to the maintenance program to include these inspections on a repetitive basis. This amendment is prompted by reports of seizure and consequent jamming of the flight control cable tension regulators and gust lock mechanisms. The actions specified in this AD are intended to prevent the flight control cable tension regulators from jamming, which could result in the inability to achieve full deflection of the associated flight control surfaces, and lead to reduced controllability of the airplane.
2007-14-01: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A330 and A340 airplanes. This AD requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.
2001-04-05: This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Model 1900D airplanes that are equipped with a KLN-90B Global Positioning System (GPS) incorporated in accordance with AlliedSignal Supplemental Type Certificate (STC) SA00245WI-D. This AD requires rewiring the KLN-90B GPS to eliminate the possibility of inconsistent NAV "FLAG" displays. This AD is the result of an instance where the copilot's NAV "FLAG" display was based on the pilot's NAV source validity. The actions specified by this AD are intended to assure that the copilot's NAV "FLAG" displays are based on the copilot's selected NAV source. Inconsistent NAV "FLAG" displays could cause the copilot to make decisions based on an invalid GPS source without knowing it was invalid.
2018-05-05: We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted by reports of a loose screw on certain slat mechanical stop assemblies, and punctures in certain fuel caps. This AD requires a one-time inspection, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.
2001-03-08: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 series airplanes, that currently requires, among other actions, certain revisions to the Airplane Flight Manual; and removal of all elevator flutter dampers. That AD also requires installation of new elevator flutter dampers, and replacement of shear pins and shear links with new improved shear pins and shear links. This amendment adds airplanes to the applicability of the existing AD; and requires replacing certain shear pins with new, improved shear pins; and, for certain airplanes, inspection of the maintenance records to determine replacement status of the shear pins; and corrective actions, if necessary. 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 premature failure of the shear pins of the elevator damper, which may increase the likelihood of jamming or restricting movement of the elevator and the resultant adverse effect on controllability of the airplane.
