2002-12-15:
This amendment supersedes an existing airworthiness directive (AD), that is applicable to Pratt & Whitney PW4000 series turbofan engines. That AD requires operators to perform initial and repetitive inspections for cracking of high pressure compressor (HPC) front drum rotors based on cycle usage. That AD also requires the removal from service of any cracked HPC front drum rotors. This amendment clarifies inspection requirements for cracking of HPC front drum rotors that have fewer than 1,000 cycles-since-new (CSN). This amendment is prompted by comments from operators seeking more clarity about the inspection requirements of paragraph (a)(1) of that AD. The actions specified by this AD are intended to prevent HPC drum rotor failure from cracks that could result in an uncontained engine failure and damage to the airplane.

52-25-01 DOUGLAS: Applies to All Models DC3 Aircraft Equipped With Vacuum Systems. \n\n\tTo be accomplished not later than May 1, 1953. \n\n\tTo guard against the possibility of excessive air temperatures and associated fire hazards in the vacuum system discharge line, one of the following modifications must be accomplished: \n\n\t1.\tInstall a fusible plug in the side of the vacuum pump discharge port at right angles to the axis of the discharge port boss. Some pumps incorporate a plugged hole in the discharge port which may be enlarged to a 3/8-inch pipe tapped hole to accommodate the fusible plug. This plug should employ an AN 840-8D fitting with a binary eutectic mixture of 67.8 percent tin and 32.2 percent cadmium, which has a melting point of 351 degrees F. A drawing describing the design of such a plug is shown in Figure 2. The 3/8-inch plug fitting is intended for pumps such as the Model 3P-211 and 3P-485. For smaller pumps such as the 3P-207, an AN 840-6D fitting, incorporating the same modification as shown below, should be used. Brass fittings of the same design as the above dual fittings are acceptable. Incorporation of an overboard drain line clamped to the fusible plug is recommended but is not mandatory. On installations which do not use an overboard discharge line the possibility exists that the plug may damage other nacelle components if it can hit them upon being blown out of the adapter at high velocity. Therefore, if no overboard discharge line is provided, the installation must be made in such a manner that the plug will not be directed toward any vulnerable components when it issues from the adapter, or \n\n\t2.\tEmploy an oil separator equivalent in principle to the Genisco No. 40081 incorporating a pressure relief valve which can be disassembled for cleaning. \n\n\t(Douglas Service Letter A-129-T-1271/WB-11-Q-4 dated April 1, 1949, covers this type modification.)

2019-14-13:
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This AD was prompted by reports of uncommanded fore/aft movements of the Captain's and First Officer's seats. This AD requires an identification of the part number, and if applicable the serial number, of the Captain's and First Officer's seats, and applicable on- condition actions. This AD also requires a one-time detailed inspection and repetitive checks of the horizontal movement system of the Captain's and First Officer's seats, and applicable on-condition actions. This AD also provides an optional terminating action for the repetitive checks of the horizontal movement system for certain airplanes. The FAA is issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-200 Freighter, A330-300, A340-200, A340- 300, A340-500, and A340-600 series airplanes. This AD requires a detailed inspection of the girt installation of each escape slide and slide raft, and corrective action if necessary. This AD was prompted by a report of incorrect installation of the girt panel on passenger doors and an incorrectly installed quick release (girt) bar into the
[[Page 63081]]
girt panel of the slide raft. We are issuing this AD to detect and correct incorrect girt installation of the escape slide and slide raft, which could prevent slide deployment during an emergency, and result in reduced evacuation capacity from the airplane and possible injury to occupants.
