2020-14-03: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-300, -400, and -500 series airplanes. This AD was prompted by a report that a crack indication consistent with fatigue cracking was found on the left nacelle support overwing fitting flange fastener hole during teardown of a Model 737-300 series airplane. This AD requires a general visual inspection of the strut to wing diagonal brace at a certain location for cracking. For certain airplanes, this AD also requires an ultrasonic inspection of the nacelle support overwing fitting at certain fastener locations for cracking. For certain other airplanes, this AD requires a magnetic check of the nacelle support overwing fitting at a certain location to determine the material composition. This AD requires applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2018-16-13: We are adopting a new airworthiness directive (AD) for certain Zodiac Seats France, 537-Series Cabin Attendant Seats. This AD was prompted by operator reports that safety belt wear was found at the attachment to the cabin attendant seat. This AD requires inspecting the safety belt webbing, and modifying and re-marking each affected cabin attendant seat. We are issuing this AD to address the unsafe condition on these products.
95-06-06: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9, DC-9-80, and C-9 (military) series airplanes and Model MD-88 airplanes, that requires a visual inspection to verify proper installation of the wire termination lugs on the ignition selector switch, and removal and correct installation of any improperly installed wire termination lugs. This amendment also requires application of sealant to the wire termination lugs and the attachment screws. This amendment is prompted by a report that, during the manufacturer's production flight testing, an abnormal engine start valve open annunciation for engine No. 2 occurred and resulted in an uncontained failure of the engine starter. The actions specified by this AD are intended to prevent damage to the engine cowling, damage to adjacent engine components, and possible fire in the cowling, due to an uncontained failure of the engine starter.
2008-08-14: This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2008-06-51 that was sent previously to all known U.S. owners and operators of Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO, and HIO series reciprocating engines, TCM TSIO-360-RB reciprocating engines, and Superior Air Parts, Inc. IO-360 series reciprocating engines with certain Precision Airmotive LLC RSA-5 and RSA-10 series fuel injection servos. This AD results from eighteen reports of fuel injection servo plugs, part number (P/N) 383493, that had loosened or completely backed out of the threaded plug hole on the regulator cover of the fuel injection servo. These servo plugs were installed with servo plug gasket, P/N 365533, under the plug hex-head. We are issuing this AD to prevent a lean running engine, which could result in a substantial loss of engine power and subsequent loss of control of the airplane.
2001-15-33: This amendment supersedes an existing airworthiness directive (AD), applicable to all BAe Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ series airplanes, that currently requires a one-time inspection for "drill marks" and corrosion on the underside of the wing top skin, and corrective actions, if necessary. For certain airplanes, this amendment requires repetitive inspections for "drill marks" or corrosion on the underside of the wing top skin, and corrective actions, if necessary, until all corrective actions and protective treatment actions are done. For certain airplanes, this amendment adds a requirement for one-time detailed and borescopic inspections of the fuel tank, pump, and stringers for paint debris and inadequacy of the existing protective treatment coating; 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 corrosion from developing on the underside of the top skin of the center wing, which could result in reduced structural integrity of the airplane.
2010-04-06: 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: An in-flight engine shutdown incident was reported on an aircraft equipped with a TAE 125-01 engine. This was found to be mainly the result of a blockage of the scavenge oil gear pump due to a broken axial bearing of the turbocharger. The broken parts were sucked into the oil pump and caused seizure. With the pump inoperative, the separator overfilled, causing the engine oil to escape via the breather vent line. This caused a loss of oil that resulted in the engine overheating and subsequent shutdown. We are issuing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft.
2001-15-24: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B16 series airplanes, that requires modification of the wiring for the internal fuel/defuel panel. The actions specified by this AD are intended to prevent the loss of engine and fuel indications essential for safe flight and landing. This action is intended to address the identified unsafe condition.
95-06-05: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-200 and -300 series airplanes. This action requires inspections to detect cracking of the fuselage frames at certain locations below the lower jamb of the upper deck main cargo door, and repair, if necessary. This amendment is prompted by reports of fatigue cracking in the fuselage frames at these locations. The actions specified in this AD are intended to prevent rapid decompression of the airplane due to fatigue cracking in the fuselage frames of the main deck cargo door.
2008-08-04: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A318, A319, A320, and A321 airplanes. That AD currently requires repetitive inspections for cracking in the forward lug of the support rib 5 fitting of both main landing gear (MLG), and repair if necessary. The existing AD also provides optional terminating actions for certain airplanes, as well as other optional methods for complying with the inspection requirements of the existing AD. This new AD continues to require repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right MLG at new repetitive intervals in accordance with new service information, and repair or replacement of any cracked MLG fitting if necessary. This new AD also requires modification of the rib bushings of the left and right MLG, which would end the repetitive inspections. This AD results from cracks found in the forward lug of the MLG support rib 5 fitting.We are issuing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing.
2020-12-12: The FAA is adopting a new airworthiness directive (AD) for all Yabor(atilde) Ind(uacute)stria Aeron(aacute)utica S.A. Model ERJ 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of cracks discovered on the engine pylon inboard lower link lugs. This AD requires repetitive detailed inspections of the engine inboard and outboard engine pylon lower link lugs for cracking, and repair if necessary, as specified in an Ag(ecirc)ncia Nacional de Avia(ccedil)(atilde)o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
