B. Alternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Western Aircraft Certification Office, FAA, Northwest Mountain Region. C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD. All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Sperry Corporation, Aerospace & Marine Group, P.O. Box 29000, Phoenix, Arizona 85038-9000.

2005-01-01: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319 and A320-200 series airplanes, that currently requires repetitive inspections to detect loose, missing, or discrepant rivets in specified areas of the door frames of the overwing emergency exits; measurement of the grip length of all rivets in the specified areas; and corrective action if necessary, which terminates the repetitive inspections. This new amendment also requires an inspection for correct dimensions of the interior countersinks of the rivet holes, and related corrective action. The actions specified by this AD are intended to prevent loose, missing, or discrepant rivets, which could lead to reduced structural integrity of the door frames of the overwing emergency exits. This action is intended to address the identified unsafe condition.
2023-10-09: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of damaged decompression panels from operators. This AD requires repetitive inspections for damaged fastener holes on the vertical and bottom edges of the inward and outward blowing decompression panels installed on the forward and aft cargo compartment vertical sidewall linings and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2023-11-06: The FAA is adopting a new airworthiness directive (AD) for certain Engine Alliance (EA) Model GP7270, GP7272, and GP7277 engines. This AD was prompted by a manufacturer investigation that revealed that certain high-pressure turbine (HPT) interstage seals were manufactured from material suspected to contain iron inclusion. This AD requires replacement of the affected HPT interstage seals. The FAA is issuing this AD to address the unsafe condition on these products.
82-06-04: 82-06-04 CANADAIR: Amendment 39-4344. Applies to Model CL-600 airplanes serial numbers 1005, 1007, 1011 thru 1013, and 1016 thru 1019, certificated in all categories. To prevent jamming of the main entry door unlatching system, accomplish the following, unless already accomplished. 1. Within the next 25 hours time in service after the effective date of this AD, perform the door handle operation check and handle adjustments described in paragraph 2 of Canadair Alert Service Bulletin A600-0077 dated July 27, 1981. 2. Replace the existing clear plastic handle guard, Part Number 600-31710-1, with guard assembly, Part Number 600-31772-1, in accordance with paragraph 2 of Canadair Alert Service Bulletin A600-0074 dated July 20, 1981. 3. Ensure that the internal door "EMERGENCY EXIT" placard located to the left hand side of the inner door handle is an approved placard reading as follows: EMERGENCY EXIT PULL AND TURN HANDLE TO "OPEN" PUSH DOOR 4.Airplanes may be flown in accordance with FAR 21.197 to a maintenance base for accomplishment of the inspection required by this AD. 5. Alternate methods of compliance with this AD may be used when they provide an equivalent level of safety and are approved by the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Mountain Region. The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). This amendment becomes effective March 22, 1982.
2000-09-11: This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F.28 Mark 0070 series airplanes. This action requires a one-time inspection to detect loose bolts attaching the gustlock counter-bracket to the pulley on the elevator tension regulator assembly, and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent restricted elevator movement and consequent reduced controllability of the airplane.
2005-01-05: The FAA is superseding an existing airworthiness directive (AD), which applies to certain EMBRAER Model EMB-135 and EMB-145 series airplanes. That AD currently requires replacing the nose landing gear wheel nuts and associated inner and outer seals, and reidentifying the landing gear strut. This new AD adds an airplane to the applicability and revises a part number for a replacement part. This AD is prompted by a report of an invalid part number for the new nose landing gear wheel nut. We are issuing this AD to prevent separation of the wheels from the nose landing gear due to the failure of the outer wheel bearings, and consequent loss of control of the airplane during takeoff and landing.

2023-11-02: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series 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.
2014-13-14: We are adopting a new airworthiness directive (AD) for certain Airbus Model A310 series airplanes. This AD was prompted by a report of an electrical arc and a hydraulic haze in the wheel bay of the left- hand main landing gear (MLG), possibly resulting from chafing between a hydraulic high pressure hose and electrical wiring of the green electrical motor pump (EMP). This AD requires modification of the electrical routing and replacement of the union elbows. We are issuing this AD to prevent chafing of hydraulic pressure hoses and electrical wiring of the green EMPs, which, in combination with a system failure, could cause an uncontrolled and undetected fire in the MLG bay.
