2002-23-16: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-90-30 airplanes. This action requires replacement of the Captain's and First Officer's chart holder assemblies on the cockpit control columns with new, improved assemblies. This action is necessary to prevent interference between the cockpit control wheels and the chart holder assembly, which could result in restricted movement of the control wheel travel when rotating the right- and left-wing-down, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2024-08-03: The FAA is adopting a new airworthiness directive (AD) for all Britten-Norman Aircraft, Ltd. Model BN-2, BN-2A, BN-2A-2, BN-2A-3, BN- 2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B- 20, BN-2B-21, BN-2B-26, BN-2B27, BN-2T, BN2T-4R, and BN2T-4S airplanes; and Model BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 airplanes. This AD is prompted by reports of electrical cable (Koiled Kord) and flight control cables interference with the control column. This AD requires inspecting for interference between the control column, rudder pedal adjuster cable, and any wiring (including the Koiled Kord) concurrently with performing a flight control full and free movement inspection, and taking corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
97-10-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Jetstream Model 4101 airplanes, that requires repetitive detailed visual inspections to detect cracks on frame 179 at the attachment bracket for the door restraint cable, and various follow-on actions. This amendment also requires installation of new doublers and stress pads on frame 179, which would terminate the repetitive inspections. This amendment is prompted by reports of cracks in frame 179 of the fuselage at the attachment bracket for the door restraint cable on in-service airplanes due to improper rigging of the door restraint system. The actions specified by this AD are intended to prevent such cracking, which could result in structural failure of the fuselage and consequent rapid decompression of the pressurized section of the fuselage.
2024-06-03: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-8 and 737-9 airplanes. This AD was prompted by a determination that the loss of a ground through the P6 panel results in the failure of the standby power control unit (SPCU). The loss of the SPCU and ground through the P6 panel could result in the loss of significant flightcrew instrumentation and displays. This AD requires installing two bonding jumpers from the P6 panel structure to primary structure. The FAA is issuing this AD to address the unsafe condition on these products.
2002-23-09: This amendment supersedes an existing airworthiness directive (AD), that is applicable to MT-Propeller Entwicklung GMBH Models MTV-9-B-C and MTV-3-B-C propellers. That AD currently requires initial and repetitive inspections of Torx head blade root lag screws that are used on certain serial number (SN) propellers and replacement of all lag screws on the propeller if any screws are found broken or with insufficient torque. In addition, that AD currently requires the replacement of certain part number (P/N) Torx head blade root lag screws with improved, hexagonal head blade root lag screws. This amendment requires the expansion of the applicability from certain SN propellers to all propellers with certain SN blades that may contain the suspect Torx head blade root lag screws. This amendment is prompted by FAA awareness that a propeller hub of an affected propeller could be changed, thereby changing the propeller serial number, creating a propeller that is not listed in the AD and that has affected blades and lag screws. The actions specified by this AD are intended to prevent failure of the blade root lag screw, which could result in propeller blade separation and loss of control of the airplane. DATES: Effective December 30, 2002. The incorporation by reference of certain publications, as listed in the regulations, was approved previously by the Director of the Federal Register as of July 23, 1999 (64 FR 36777, July 8, 1999).
2002-23-07: This amendment adopts a new airworthiness directive (AD) that applies to all aircraft (specifically balloons) that incorporate certain Cameron Balloons Ltd. (Sky Balloons) Mk1 (BR1) & Mk2 (Mistral) burners. This AD requires you to replace the valve stems of the main blast, liquid fire, and pilot light valves. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to correct the mechanical failure of the valve stem/seat pinned joint, which could result in a propane vapor leak. Such failure could lead to a propane explosion and fire.
2024-05-10: 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 a report of multiple occurrences of low clearance or fouling between certain wiring harnesses and a hydraulic bracket and structure in the wing trailing edge area that were detected on the production line. This AD requires inspecting certain wiring harnesses for any damage and clearance to adjacent structure and corrective actions, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2002-23-05: This amendment adopts a new airworthiness directive (AD), applicable to certain Cessna Model 750 airplanes, that requires replacement of reset circuit breakers for the auxiliary hydraulic pump system and the King KHF 950 high frequency communication system(s) with new circuit breakers. This amendment is prompted by a report from the airplane manufacturer indicating that the trip levels for the reset circuit breakers installed in the auxiliary hydraulic pump system and the King KHF 950 high frequency system(s) are too high, which can prevent corresponding high current remote control circuit breakers from tripping when excessive electrical loads are present. The actions specified by this AD are intended to prevent overloading of the affected airplane electrical wiring and circuits, which could result in a fire.
96-05-04: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires the installation of a control cable guard to separate the flight control cables from the electrical wiring of the aft left cabin attendant console. This amendment is prompted by reports of burnt electrical wire cable in the cabin attendant console that was caused by chafing of the wire cable against certain flight control cables. The actions specified in this AD are intended to prevent chafing of these wire cables, which could result in a fire hazard or damage to critical flight control cables.
2018-02-12: We are superseding Airworthiness Directive (AD) 2016-02-01, which applied to certain Airbus Model A320-211, -212, and -231 airplanes. AD 2016-02-01 required repetitive inspections to detect cracks of the pressurized floor fittings at a certain frame, and renewal of the zone protective finish or replacement of fittings with new fittings if necessary. AD 2016-02-01 also provided an optional modification that was terminating action for the repetitive inspections. This new AD retains the requirements of AD 2016-02-01, and requires accomplishment of the modification that was optional in AD 2016-02-01. This AD was prompted by the results of an additional fatigue analysis of cracking of the pressurized floor fittings and a determination that the optional modification should become a required action. We are issuing this AD to address the unsafe condition on these products.
