2006-01-03: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B2 and B4 series airplanes. This AD requires repetitive replacement of the angle of attack (AOA) sensors with new or overhauled AOA sensors. This AD also provides an optional terminating action for the repetitive replacements. This AD results from reports of several false stall warnings associated with stick-shaker activation, occurring during take-off. We are issuing this AD to prevent false stall warnings associated with stick-shaker activation, which could result in increased pilot workload as the pilot tries to determine the cause of the stall warning and possible reduction in the pilot's ability to control the airplane.

97-13-04: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300-B2 and -B4 series airplanes, that currently requires an inspection to detect discrepancies of a certain thrust reverser control lever spring; an operational test to verify the integrity of the flight inhibition circuit of the thrust reverser system; and either the correction of discrepancies or deactivation of the associated thrust reverser. That AD also provides for an optional terminating action. That AD was prompted by a report that, due to broken and deformed thrust reverser control lever springs, an uncommanded movement of the thrust reverser lever to the unlock position and a reverser unlock amber warning occurred on one airplane. The actions specified by that AD are intended to detect such broken or deformed control lever springs before they lead to uncommanded deployment of a thrust reverser and consequent reduced controllability of the airplane. This amendment requires installation of the previously optional terminating action in accordance with the latest service information.

2005-25-14: The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires modifying the wiring of the starter-generator terminal block. This AD results from a report of total electrical failure just as the airplane landed. We are issuing this AD to prevent total electrical failure and consequent reduced controllability of the airplane.
2005-25-05: The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, -11, -15, -15A, -17, -17A, -17R, and -17AR series turbofan engines. That AD currently requires revisions to the engine manufacturer's time limits section (TLS) to include enhanced inspection of selected critical life- limited parts at each piece-part opportunity. This AD modifies the airworthiness limitations section of the manufacturer's manual and an air carrier's approved continuous airworthiness maintenance program to add an eddy current inspection. An FAA study of in-service events involving uncontained failures of critical rotating engine parts has indicated the need for mandatory inspections. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
47-47-11: 47-47-11 REPUBLIC: (Was Mandatory Note 14 of AD-769-2.) Applies to Model RC-3 Aircraft. Compliance required as soon as possible but in any event not later than January 15, 1948. To prevent inadvertent reversal of propeller if propeller reverse control wire fails at control valve attachment, install spring between the reverse control link and the bracket supporting the reverse control. (Seabee Service Bulletin No. 21 dated October 14, 1947, covers this subject.)
66-05-03: 66-05-03 LOCKHEED: Amdt. 39-182 Part 39 Federal Register January 19, 1966. Applies to Models 188A and 188C Series Airplanes. Compliance required as indicated, unless already accomplished. To detect fatigue cracks emanating from the barrel-nut access holes of the outer wing front cap fittings at the Wing Station 65 joint, accomplish the following: (a) Inspect lower cap fittings, P/N's 807352-1 and -2, by visual means, for cracks emanating from the barrel-nut access holes within the next 1,100 hours' time in service after the effective date of this AD. (b) Inspect lower and upper cap fittings, P/N's 807352-1 and -2 and P/N's 807354-1 and -2, by dye penetrant method or an FAA-approved equivalent, for cracks emanating from the barrel-nut access holes and by visual means for burrs at the forward edge of the access holes within the next 3,000 hours' time in service after compliance with (a). (c) Replace any cracked fittings found during the inspections required by (a)or (b) before further flight, with new deburred fittings of the same part number, except that the airplane may be flown in accordance with FAR 21.197 to a base where the repair can be made. (d) Deburr uncracked fittings on which burrs have been found during the inspection required by (b), before further flight, in accordance with Lockheed Service Bulletin 88/SB-633B, Section 2.D.(4) or later FAA-approved revision, except that the airplane may be flown in accordance with FAR 21.197 to a base where the repair can be made. This directive effective February 19, 1966.
2005-24-06: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A318-100, A319-100, A320-200, A321-100, and A321-200 series airplanes, and Model A320-111 airplanes. This AD requires an inspection to determine whether certain braking and steering control units (BSCUs) are installed or have ever been installed. For airplanes on which certain BSCUs are installed or have ever been installed, this AD requires an inspection of the nose landing gear (NLG) upper support and corrective action if necessary, and a check of the NLG strut inflation pressure and an adjustment if necessary. For some of these airplanes, this AD also requires a revision to the aircraft flight manual to incorporate an operating procedure to recover normal steering in the event of a steering failure. This AD results from a report of an incident where an airplane landed with the NLG turned 90 degrees from centerline. We are issuing this AD to prevent landings with the NLG turned 90 degrees from centerline, which could result in reduced controllability of the airplane.
46-13-05: 46-13-05 DOUGLAS: (Was Mandatory Note 10 of AD-618-3 and Mandatory Note 12 of AD-669-3.) Applies to All DC3 Aircraft. \n\n\tTo be accomplished not later than April 1, 1947. \n\n\tReplace all canvas control boot assemblies either with the new rubber control column boot assemblies of the same part number (No. 5035184-16 and -17), as called for on Douglas Service Bulletin No. 231, or with the following boot assemblies: \n\n\t(a)\tThompson Co.
