2022-24-04: The FAA is superseding Airworthiness Directive (AD) 2022-07- 05, which applied to certain MarS A.S. emergency parachutes. AD 2022- 07-05 superseded AD 2022-05-09, expanded the applicability, and required removing all emergency parachutes manufactured since 2016. Since the FAA issued AD 2022-07-05, MarS A.S. developed a modification for the emergency parachutes to correct the unsafe condition. This AD requires modifying and re-identifying the emergency parachutes. The FAA is issuing this AD to address the unsafe condition on these products.
2007-21-15: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 707 airplanes and Model 720 and 720B series airplanes. This AD requires identifying the material used in the elevator hinge support fittings of the horizontal stabilizer trailing edge, doing repetitive detailed inspections for cracking of the fittings and corrective actions if necessary, and doing an eventual terminating action. This AD results from a report that stress corrosion cracking of the elevator hinge support fittings has been discovered on several Model 707 airplanes. We are issuing this AD to prevent cracking of the elevator hinge support fittings, which could reduce the elevator support stiffness and lead to in-flight airframe vibration, consequent damage to the elevator and horizontal stabilizer, and reduced controllability of the airplane.
2022-23-11: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of discrepancies between the center wing tank (CWT) fuel quantity, as indicated by the fuel quantity indicating system (FQIS), and the refueling truck uploaded fuel amount, followed by certain engine-indicating and crew-alerting system (EICAS) messages. This AD requires installing new software in the fuel quantity processor unit (FQPU), or replacing the FQPU with one that includes new software, depending on airplane configuration; doing a software version check; and doing a FQPU operational check, depending on airplane configuration. This AD also prohibits the installation of certain FQPUs on certain airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
2007-21-12: We are adopting a new 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: It has been found cases in which some wiring harnesses were not protected in accordance with SFAR-88 (Special Federal Aviation Regulation No. 88) requirements. The potential of ignition sources, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2007-21-09: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: As a result of a fault report from a Stemme S10-VT operator, an investigation of the differential fuel pressure sensor 11AB-K01 was performed. The fault report describes a fuel leak through the air pressure line into the airbox. The fuel escaped through the drainage tubes. As a result of this investigation, the possibility of a leak to the engine compartment cannot be excluded. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
2022-22-09: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-1041 airplanes. This AD was prompted by a report of rejected take-offs after transient engine N1 shaft speed exceedance. This AD requires replacing certain hydro-mechanical units (HMUs) with serviceable HMUs before reaching a reduced life limit, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
2007-20-07: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you to inspect the starter-generator to determine the serial number (S/N) and suffix letter, which indicates if the part is improperly shimmed. This AD also requires you to replace any improperly shimmed starter- generator with a properly shimmed starter-generator. This AD results from reports of a manufacturing error where certain starter-generators may have been improperly shimmed. We are issuing this AD to detect and correct improperly shimmed starter-generators, which could result in premature starter-generator failure. This failure could lead to increased chances of dual starter-generator failure on the same flight.
2022-21-12: The FAA is adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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.
2007-20-03: We are adopting a new 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: The aim of this AD, is to mandate airworthiness requirements in structural maintenance in accordance with the requirements defined in the AIRBUS A300-600 Airworthiness Limitations Items (ALI) document issue 11, referenced AI/SE-M2/95A.0502/06, approved by EASA on 31 May 2006. The unsafe condition is fatigue cracking, damage, or corrosion in principal structural elements, which could result in reduced structural integrity of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2022-21-03: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by reports that the engine feed pressure switches were installed with no secondary locking mechanism and can become loose and cause a fuel leak. This AD requires initial and repetitive inspections at the engine feed pressure switch locations and installation of a flange adaptor with lockwire to terminate the repetitive inspections, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
