2008-14-08: We are adopting a new airworthiness directive (AD) for all Boeing Model 747 airplanes listed above. This AD requires repetitive inspections for broken or missing fasteners in the single-row hinge fasteners of the forward and aft cargo doors, and related investigative/corrective actions. This AD results from reports of broken and missing fasteners in the hinges of the forward and aft cargo doors in both the body hinge segments and the door hinge segments. We are issuing this AD to detect and correct broken or missing fasteners in the hinge segments with a single fastener row, which could lead to opening of the cargo door during flight and result in rapid decompression of the airplane.

2008-13-20: We are adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes equipped with Rolls Royce RB211-535E engines. This AD requires repetitive inspections for signs of damage of the aft hinge fittings and attachment bolts of the thrust reversers, and related investigative and corrective actions if necessary. This AD results from reports of several incidents of bolt failure at the aft hinge fittings of the thrust reversers due to, among other things, high operational loads. We are issuing this AD to prevent failure of the attachment bolts and consequent separation of a thrust reverser from the airplane during flight, which could result in structural damage to the airplane.
87-26-04: 87-26-04 BRITISH AEROSPACE (BAe): Amendment 39-5804. Applies to Model BAe- 146 series airplanes listed in BAe Service Bulletin 24-30-00757A, Revision 1, dated September 5, 1986, certificated in any category. Compliance is required within 6 months after the effective date of this AD, unless previously accomplished. To prevent battery depletion and subsequent loss of Essential DC and Emergency DC busbars accomplish the following: A. Modify the DC power distribution in accordance with British Aerospace BAe-146 Aircraft Modification Service Bulletin 24-30-00757A, Revision 1, dated September 5, 1986. B. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety and which has the concurrence of an FAA Principal Maintenance Inspector, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region. C. Special flight permits may be issued in accordance with FAR 21.197and 21.199 to operate airplanes to a base for the accomplishment of the modifications required by this AD. All persons affected by this directive who have not already received the appropriate service document from the manufacturer may obtain copies upon request to British Aerospace, Inc., Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, D.C. 20041. This document may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington. This amendment becomes effective February 1, 1988.
2008-13-11: 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: \n\n\tService experience indicates that as aircraft become older, they are more likely to exhibit indications of corrosion. \n\nAdditionally, the FAA has reviewed the service experience and finds this action to be necessary based upon that service experience. We are issuing this AD to require actions to correct the unsafe condition on these products.
82-06-08: 82-06-08 SIKORSKY AIRCRAFT DIVISION: Amendment 39-4348. Applies to Model S-76A helicopters, prior to S/N 760207, certificated in all categories. Compliance is required within the next 50 hours' time in service after the effective date of the AD unless already accomplished. To prevent possible loss of both DC generators due to loss of ground, modify DC junction box ground circuits in accordance with Sikorsky Alert Service Bulletin 76-24-7, dated February 3, 1982, or an equivalent means of compliance approved by the Chief, Boston Aircraft Certification Branch, Aircraft Certification Division, New England Region, Federal Aviation Administration. This amendment becomes effective March 22, 1982.
2008-12-11: We are adopting a new airworthiness directive (AD) for Agusta S.p.A. Model A109E, A109S, and A119 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the technical agent for Italy, with which we have a bilateral agreement, states in the MCAI: During a ground test of the emergency door release system, the Pilot doors failed to disengage. Investigation determined that the reason of this malfunction is interference between the lower hinge and the fuselage structure. This condition, if not corrected, creates the risk of non-disengagement of the Pilot- and/or Co-pilot doors during an emergency, inhibiting the evacuation of the aircraft, possibly resulting in injuries to the occupants. This AD requires actions that are intended to address the unsafe condition caused by interference between thepilot or co-pilot door lower hinge and the fuselage structure.
89-10-05: 89-10-05 BRITISH AEROSPACE: Amendment 39-6212. Applicability: Model BAe 125-800 series airplanes, Serial Numbers 8091 to 8147, certificated in any category. Compliance: Required within 7 days after the effective date of this AD, unless previously accomplished. To prevent loss of electrical power and eliminate a potential fire hazard, due to chafed cable looms, accomplish the following: A. Perform a one-time inspection of the electrical cable looms above panel DA-E for cable chafing and adequate clearance from adjacent equipment, in accordance with British Aerospace Service Bulletin 24-270, dated March 20, 1989. If any cable is chafed or if clearance is insufficient, prior to further flight, repair in accordance with the service bulletin. B. Alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who may concur or comment, and then send it to the Manager, Standardization Branch, ANM-113. C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of the requirements of this AD. All persons affected by this directive who have not already received the appropriate service information from the manufacturer may obtain copies upon request to British Aerospace, PLC, Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, D.C. 20041. This information may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington or Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington. This amendment (39-6212, AD 89-10-05) becomes effective on May 26, 1989.
2000-23-31: This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9-82 (MD-82) and DC-9-83 (MD-83) series airplanes, and Model MD-88 airplanes. This action requires deactivating the left and right lower sidewall lights located in the passenger compartment. This action is necessary to prevent arcing and heat damage of the Luminator fluorescent lamp holders located outboard of the Passenger Service Unit panel, which could result in smoke and fire in the passenger compartment. This action is intended to address the identified unsafe condition.\n\n\tThe incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 13, 2000.\n\n\tComments for inclusion in the Rules Docket must be received on or before January 29, 2001.
