2001-08-26: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A319 and A320 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to specify procedures for landing under certain conditions of gusty winds and turbulence. This action is prompted by a report of a recent hard landing on a Model A320 series airplane equipped with ELAC L80 standard, which was caused by activation of the high angle-of-attack protection during a landing in gusty winds and turbulence. This action is necessary to prevent activation of the high angle-of-attack protection during final approach for landing, which could result in loss of ability to flare properly during landings. This action is intended to address the identified unsafe condition.
2019-22-05: The FAA is superseding Airworthiness Directive (AD) 2017-23- 06, for certain General Electric Company (GE) CF34-8C1, CF34-8C5, CF34- 8C5A1, and CF34-8C5B1 engines. AD 2017-23-06 required an inspection of the bleed air manifold link rod assemblies and the supply, return, and drain fuel fittings on the operability bleed valve (OBV). This AD requires repetitive inspections of the OBV fuel tubes, OBV bleed air manifold link rod assemblies, and the OBV fuel fittings and replacement of OBVs or related hardware that fail inspection. In addition, this AD expands the applicability of these inspections to include additional GE CF34-8C model turbofan engines. This AD was prompted by multiple engine fires that have occurred as a result of malfunctions related to the OBV. The FAA is issuing this AD to address the unsafe condition on these products.
94-04-17: This amendment adopts a new airworthiness directive (AD) that applies to Twin Commander Aircraft Corporation (Twin Commander) 500, 520, 560, 680, 681, 685, 690, 695, and 720 series airplanes. This action requires inspecting the flap system for cables with broken wires or pulleys with worn cable clips, replacing any damaged parts, and replacing the master pulley and cable with new parts of improved design. Reports of cable fatigue, particularly the master pulley cable, on several of the affected airplanes prompted this action. The actions specified by this AD are intended to prevent flap system failure caused by cable fatigue, which could result in loss of control of the airplane.
2007-21-04: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This AD requires doing an initial detailed inspection for cracks in the aft pressure bulkhead web; repairing any discrepancy; and doing repetitive detailed inspections, and doing related investigative actions, if necessary. This AD results from reports of cracking in the aft pressure bulkhead web. We are issuing this AD to detect and correct a cracked pressure bulkhead web, which could result in rapid decompression of the airplane.
2001-08-14: This amendment adopts a new airworthiness directive (AD), that is applicable to Turbomeca S.A. Arrius Models 2B, 2B1, and 2F turboshaft engines. This amendment requires the replacement of the right injector half manifold, left injector half manifold, and privilege injector pipe. This amendment is prompted by reports from the Direction Generale de L'Aviation Civile (DGAC), which is the airworthiness authority for France, of partially or totally blocked fuel injection manifolds, which were found during inspections at a repair workshop. The actions specified by this AD are intended to prevent engine flameout during rapid deceleration, or the inability to maintain the 2.5 minutes one engine inoperative (OEI) rating. The actions are also intended to prevent air path cracks, due to blockage of the fuel injection manifolds.
2019-22-10: The FAA is superseding Airworthiness Directive (AD) 2019-20- 02, which applied to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2019-20-02 required repetitive inspections for cracking of the left- and right-hand side outboard chords of frame fittings and failsafe straps at a certain station around two fasteners, and repair if any cracking is found. This AD also requires repetitive inspections for cracking of the left- and right-hand side outboard chords of frame fittings and failsafe straps at a certain station, but expands the inspection to the area around eight fasteners, and also requires repair if any cracking is found. This AD was prompted by a determination that the inspection area needs to be expanded. The FAA is issuing this AD to address the unsafe condition on these products.
2003-18-04: The FAA is adopting a new airworthiness directive (AD) for Wytwornia Sprzetu Komunikacyjnego (WSK) PZL-10W turboshaft engines. This AD requires a one-time inspection of the four engine-to-gearbox pin retaining joints for loose or improperly crimped retaining nuts and damaged bolts on certain serial number engines. This AD is prompted by reports of loose or improperly crimped engine-to-gearbox pin joint retaining nuts found during overhaul. We are issuing this AD to prevent loss of nut torque and loosening of engine-to-gearbox pin joint retaining nuts, which could result in misalignment of the engine to the gearbox, causing loss of drive to the gearbox, power turbine overspeed, and uncontained power turbine disc failure.
2020-14-07: The FAA is adopting a new airworthiness directive (AD) for all Austro Engine GmbH model E4 and E4P diesel piston engines. This AD was prompted by reports of considerable wear of the timing chain and failure of fuel injectors on these engines. This AD requires replacement of the timing chain and fuel injectors on the affected Austro Engine GmbH model E4 and E4P diesel piston engines. The FAA is issuing this AD to address the unsafe condition on these products.
2001-08-19: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 series airplanes, that requires replacing certain transformer ballast assemblies in the first officer's console and electrical power center with certain new, improved ballast assemblies. This action is necessary to prevent overheating of ballast transformers due to high power demands resulting from aging, which could result in smoke in the cockpit. This action is intended to address the identified unsafe condition
2017-22-07: We are adopting a new airworthiness directive (AD) for certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231, - 232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, - 213, -231, and -232 airplanes. This AD was prompted by a report of cracks on frame forks and outer skin on the forward and aft cargo compartment doors. This AD requires repetitive inspections of the frame forks, and corrective actions if necessary. This AD also includes optional modifications that constitute terminating action. We are issuing this AD to address the unsafe condition on these products.
