2020-20-15: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-202, -203, -223, -223F, -243, -243F, - 302, -303, -323, -343, and -941 airplanes; and Model A340-313, -541, and -642 airplanes. This AD was prompted by the results of laboratory tests on non-rechargeable lithium batteries installed in emergency locator transmitters (ELTs), which highlighted a lack of protection against currents of 28 volts DC or 115 volts AC that could lead to thermal runaway and a battery fire. This AD requires modifying a certain ELT by installing a diode between the ELT and the terminal block, 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.
64-09-06: 64-09-06 SCHLEICHER: Amendment 716 Part 507 Federal Register April 18, 1964, as revised by Amendment 39-1282. Applies to Models Ka6 and K8 Gliders. Compliance required as indicated. Cracks and faulty welds have been found at the joint fitting welded to the airbrake push- pull rod and in the weld between the bearing bracket for the airbrake flap cross shaft lever and the fuselage main frame. (a) On Model Ka6 all serial numbers up to and including Serial Number 6067 and Model K8 all serial numbers up to and including Serial Number 8098, within 25 hours' time in service after the effective date of this AD, visually inspect for cracks in the joint fitting welded to the airbrake push and pull rod with at least a 3-power magnifying glass. (1) If cracks are found at the fitting welded to the airbrake push-pull rod in either Models Ka6 or K8 gliders, replace the push-pull rod with a modified part as provided for in Schleicher Modification No. 7 dated September 13, 1962, for Model Ka6 and Modification No. 9 dated September 13, 1962, for Model K8 before further flight. (2) If the inspection in (a) reveals no cracks, install the modified push-pull rod within 50 hours' time in service after the effective date of this AD. (Schleicher Modification No. 7 for Model Ka6, dated September 13, 1962, Modification No. 9 for Model K8 dated September 13, 1962, pertain to this same subject.) Amendment 716 Part 507 Federal Register April 18, 1964, became effective May 19, 1964. Revised December 2, 1964. This amendment 39-1282 becomes effective September 7, 1971.
2003-21-03: The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney Canada (PWC) models PW118, PW120, PW120A, and PW121 turboprop engines. This AD requires replacing the low pressure rotor speed (NL) sensor port sealing tube and reworking or replacing the external air tube connecting the P2.5/P3 switching valve to the rear inlet case. This AD is prompted by a report of an internal oil fire in the engine intercompressor case (ICC). A fire in the ICC could cause the existing tubes to disengage due to melted brazing on the tubes. Once these tubes disengage, the ICC fire then develops into an external fire within the engine nacelle cavity. We are issuing this AD to prevent fire in the engine nacelle cavity, in-flight engine shutdown, and airplane damage.
