78-20-09: 78-20-09 GULFSTREAM AMERICAN CORPORATION (GAC) (FORMERLY GRUMMAN AMERICAN AVIATION CORPORATION (GAAC): Amendment 39-3309. Applies to Model GA-7 serial numbers GA7-001 through GA7-0039. Compliance is required within the next 25 hours' time in service after the effective date of this AD, unless already accomplished. To prevent a hazard to the airplane caused by excessive force required to move the fuel selector valve from one position to another position, accomplish the following: (1) Remove the two original fuel selector valves, Gerdes Part Number A980-5, and install two new improved fuel selector valves, Gerdes Part Number A980-7, utilizing the procedures and precautions contained in GA-7 Maintenance Manual, Section 28-2-1, pages 202 and 204, Fuel Selector Valve Removal, and Fuel Selector Valve Installations. (2) After the Gerdes Part Number A980-7 fuel selector valve installation has been completed in accordance with the above Maintenance Manual procedures, set each selector to ON, OFF, and CROSSFEED positions while observing each selector valve to ensure that the valve operates correctly, no fuel leakage occurs, and a positive detent is noted at each position selected on the valve. (Gulfstream American Service Bulletin No. ME-10 dated August 16, 1978 applies to this same subject.) This amendment becomes effective October 9, 1978.
97-08-05: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-100, -200, and -300 series airplanes, that requires replacement of certain switches in the cabin attendant's panel at door 4 right and door 2 right with new improved switches. This amendment is prompted by reports indicating that fires have occurred on some airplanes due to the internal failure of some of these switches. The actions specified by this AD are intended to prevent the installation and use of switches that could short circuit when they fail, and consequently cause fire and smoke aboard the airplane.
2005-06-03: The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model MD-90-30 airplanes. This AD requires replacing, with improved parts, certain existing fluorescent light lamp holders located in the ceiling panels and life raft ceiling support housings, and behind the overhead stowage compartments in the main cabin. This AD is prompted by reports of failure of fluorescent light lamp holders in the main cabin. We are issuing this AD to prevent chafing of the lamp holder power wire against the mounting bracket, and moisture intrusion into the lamp holders, which could result in failure of the lamp holders and consequent smoke and fire in the airplane cabin.
2023-25-02: The FAA is adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-46-350P, PA-46-500TP, and PA-46-600TP airplanes. This AD was prompted by a report that a bearing fell out of a control column mount during routine handling prior to installation in an affected airplane and the discovery that a quality escape condition could exist on other airplanes. This AD requires inspecting the left and right control column mounts to determine if a retaining ring is installed. If a retaining ring is not installed, this AD requires inspecting the bearing in the mount block for the presence of retaining compound, and depending on the inspection results, installing a retaining ring and applying retaining compound to the bearing, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
95-19-14: This amendment adopts a new airworthiness directive (AD), applicable to certain Jetstream Model ATP airplanes, that requires modification of certain doors. This amendment is prompted by a report that an operator was unable to unlock a Type I passenger door due to migration of a shootbolt bush. The actions specified by this AD are intended to prevent such migration, which could jam the Type I passenger door, and subsequently could delay or impede the evacuation of passengers during an emergency.
2023-23-03: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter series airplanes. This AD was prompted by a widespread fatigue damage (WFD) evaluation on Airbus SAS Model A330-200 Freighter series airplanes, which found that the circumferential joint at Frame 58 (near the rear fuselage) is susceptible to WFD. This AD requires a modification to reinforce the circumferential joints at Frame 58 and, if necessary, corrective action, 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.
2005-05-18: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires repetitive detailed, low frequency eddy current, and high frequency eddy current inspections of the webs of the aft pressure bulkhead at body station 1016 for cracks, and corrective action if necessary. This AD is prompted by a report of cracks found, during fatigue testing, at several of the fastener rows in the web lap splices at the dome apex of the aft pressure bulkhead. We are issuing this AD to detect and correct fatigue cracks in the webs of the aft pressure bulkhead, which could result in rapid decompression of the airplane.
2023-23-06: The FAA is superseding Airworthiness Directive (AD) 2023-04- 13, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2023-04-13 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-04- 13 and 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.
2000-24-12: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires an inspection to detect chafing or damage of the electrical wires leading to the terminal strips in the center accessory compartment (CAC) area; and corrective actions, if necessary. This amendment also requires revising the wire connection stack up of certain cable terminals at the electrical power center bays in the CAC, and replacing certain terminal strips with new strips and removing applicable nameplates at electrical power center bays. This action is necessary to prevent arcing and sparking damage to the power feeder cables, terminal strips, and adjacent structure, and consequent smoke and fire in the CAC. This action is intended to address the identified unsafe condition.
