2021-02-12: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200 series airplanes, Model A330-200 Freighter series airplanes, Model A330-300 series airplanes, Model A330-900 series airplanes, Model A340-200 series airplanes, Model A340-300 series airplanes, Model A340-500 series airplanes, Model A340-600 series airplanes, Model A380-800 series airplanes; and Model A350-941 and -1041 airplanes. This AD was prompted by a report of a quality issue with a certain repair method of damage-through honeycomb core cargo linings by speed patches applied to both sides. This AD requires repair of each affected part, or replacement with a serviceable part, 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.
2004-03-20: This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 series airplanes, that requires repetitive general visual inspections, lubrication, and tests of the release mechanism for the service/emergency door; and corrective actions if necessary. This AD also provides an optional terminating action for the repetitive inspections and lubrication. This action is necessary to prevent failure of the release mechanism on the service/emergency door, which could result in the inability to open the service/emergency door during an emergency evacuation. This action is intended to address the identified unsafe condition.
98-03-12: This amendment adopts a new airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that requires a one-time inspection of the date stamp affixed to the wing deicing boots to determine the cure date, and replacement of the deicing boot with a new boot, 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 delamination of the wing deicing boots, and resultant inflation of the deicing boots to a distorted aerodynamic shape during flight, which could result in reduced controllability of the airplane.
95-26-18: This amendment adopts a new airworthiness directive (AD) that applies to certain Maule Aerospace Technology (Maule) M-4, M-5, M-6, M-7, MX-7, MXT-7 series and Models MT-7-235, and M-8-235 airplanes. This action requires a one-time inspection of certain wing lift struts for internal corrosion and replacement of the struts if corrosion is detected. An accident involving a wing separating from a Maule airplane in flight prompted this action. The actions specified by this AD are intended to prevent corrosion of the wing lift strut, which, if not detected and corrected, could cause the wing to separate from the airplane.
98-21-18: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes that requires replacement of the de-icing system timer with a new, improved timer. This amendment is prompted by reports of possible overheating and debonding of the propeller blade due to a failure of the de-icing system timer and a dormant short circuit in the propeller de-icer system. The actions specified by this AD are intended to prevent such overheating and debonding of the propeller blade, which could result in reduced controllability of the airplane.
2010-12-01: We are adopting a new airworthiness directive (AD) to supersede AD 2009-24-13, which applies to certain Cessna Aircraft Company (Cessna) Model 525A airplanes. AD 2009-24-13 currently requires you to repetitively inspect the thrust attenuator paddle assemblies for loose and damaged fasteners and for cracks. AD 2009-24-13 also requires you to replace loose or damaged fasteners and replace cracked thrust attenuator paddles found during any inspection. Since we issued AD 2009-24-13, Cessna has developed new design thrust attenuator paddles and universal head rivets as terminating action for the repetitive inspections. Consequently, this AD would retain the requirements of AD 2009-24-13 until replacement of both thrust attenuator paddles and the eight countersunk fasteners with new design thrust attenuator paddles and universal head rivets. We are issuing this AD to detect and correct loose and damaged fasteners and cracks in the thrust attenuator paddles, which could result in in-flight departure of the thrust attenuator paddles. This failure could lead to rudder and elevator damage and result in loss of control.
2004-03-28: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-102, -103, -106, -201, - 202, -301, -311, and -315 airplanes, that requires a one-time inspection to determine the serial numbers of the elevator and aileron servos of the drive assemblies of the automatic flight control system, and follow-on corrective actions if necessary. This action is necessary to prevent separation of the screws from the autopilot clutch assembly of the SM-300 servo, which could result in uncommanded engagement of the autopilot servo and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2010-14-14: 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 for EMBRAER Model ERJ 170 airplanes describes the unsafe condition as: It has been found the occurrence of an engine in-flight shutdown caused by the LPCV [low pressure check valves] failing to close due to excessive wear, which leads to the concern that such fault may be present in both engines of a given aircraft. * * * * * The MCAI for EMBRAER Model ERJ 190 airplanes describes the unsafe condition as: An occurrence of an uncommanded engine in-flight shutdown (IFSD) was reported * * *, which was caused by an ERJ 170 defective LPCV * * *. The valve failed to close due to excessive wear. Despite there were no IFSD related to LPCV * * * failure, some ERJ 190 valves * * * wereinspected and presented cracks due to low cycle fatigue. Since this failure mode also might lead to an engine in-flight shutdown and since both engines of the airplane have the same valves, there is a possibility of an occurrence of a dual engine IFSD due to LPCV failure. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
96-01-03: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747-100 and -200 series airplanes. This action requires a revision of the Airplane Flight Manual (AFM) and of the Airplane Weight and Balance Supplement to restrict the running load and maximum total payload to a suitable level. This amendment is prompted by a determination that these airplanes are incapable of carrying the currently certified payload limits due to the missing external structural doublers located forward of the surround structure of the main deck side cargo door, and deficiencies in the main deck floors. The actions specified in this AD are intended to prevent collapse of the aft fuselage due to inadequate strength in the airplane structure, and subsequent separation of the aft fuselage from the airplane.
2021-05-51: The FAA is adopting a new airworthiness directive (AD) for certain Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 model turbofan engines. This AD was prompted by the in-flight failure of a 1st-stage low-pressure compressor (LPC) blade on a PW4077 model turbofan engine resulting in an engine fire during flight. This AD requires performing a thermal acoustic image (TAI) inspection for cracks in certain 1st-stage LPC blades and removal of those blades that fail inspection. The FAA previously sent an emergency AD to all known U.S. owners and operators of these engines and is now issuing this AD to address the unsafe condition on these products.
