47-10-25: 47-10-25 LOCKHEED: (Was Mandatory Note 28 of AD-763-3.) Applies to All Model 49 Serials Incorporating Eclipse Type 1193, Model 1, Style A Generators on Which the Serial Numbers Are Not Followed by the Letter "M".
Compliance required prior to March 1, 1947.
Replace the 12 mounting head-to-yoke bolts in each generator with new 1/4-inch bolts (P/N 63937 referred to in Eclipse-Pioneer Bulletin No. 70).

2004-13-06: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319 and A320 series airplanes, that requires repetitive detailed inspections to detect cracks in the keel beam side panels, and repair if necessary. Accomplishment of the repair ends the repetitive inspections for that repaired area. This action is necessary to detect and correct fatigue cracks on the side panels of the keel beams, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.

2011-14-10: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
* * * * *
Following a query from an operator, investigations revealed that some MSN [manufacturer serial number], for which Airbus modification 40391 was indicated as fully embodied inside the Aircraft Inspection Report (AIR), did not have Modification Proposal (MP-S10437) which is part of this modification embodied in production.
As a result, ALI [Airworthiness Limitation Item] task 533105-01- 02 has not been performed on the MSN listed in the applicability section of this AD, which constitutes an unsafe condition.
* * * * *
The unsafe condition is fatigue cracking of the internal structure of the fuselage, which could adversely affect the structural integrity of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

To prevent the upper hot liquid container in the galley from rubbing against the electrical wire bundle and causing a fire which could result in the loss of thrust reversers, flaps, spoilers, and some airplane lights, accomplish the following:
(a) Remove upper hot liquid container in galley aft of fuselage station 112LH side.
(b) Check if electrical wire bundle located behind upper corner of container is free from chafing marks or damaged insulation.
(c) If electrical wire bundle is free from chafing marks or damage, secure all pertinent electrical outlets and install placard prohibiting the installation and use of this hot liquid container until proper routing and protection in accordance with paragraph (e) of this AD is accomplished, and return the aircraft to service.
(d) If electrical wire bundle shows chafing marks or damage, repair per standard aircraft practice and accomplish proper routing and protection in accordance with paragraph (e) of this AD, or install placard required by paragraph (c) of this AD.

96-21-08: This amendment adopts a new airworthiness directive (AD), applicable to all Short Brothers Model SD3-30 and SD3-SHERPA series airplanes, that requires inspections of the vertical fin-to-tailplane joint to detect any loose bolts; and, if necessary, inspections to detect elongation of bolt holes, and replacement with new bolts, if necessary. Additionally, this amendment requires inspections of the upper shear angle to detect pulled or loose rivets, and replacement of the shear angle using new rivets, if necessary. This amendment is prompted by reports of loose bolts in the vertical fin-to-tailplane joint and pulled or loose rivets in an upper shear angle. The actions specified by this AD are intended to prevent reduced structural integrity of the vertical fin to tailplane joint due to such discrepancies of the bolts or rivets.

49-25-01: 49-25-01 CURTISS-WRIGHT Applies to All Models of C-46 Series airplanes used in passenger operation under provisions of Part 41, 42, or 61 of the Civil Air Regulations as specified in Sections 41.20 and 61.30 and Amendment 42-8.
To be accomplished not later than the dates specified in the above amendments, as revised by Special Civil Air Regulation No. 329, and any subsequent regulations affecting these compliance dates.
When engaged in passenger-carrying operations, all applicable cargo-compartment fire- prevention measures including those concerning controls, wiring, lines, equipment, tie-down and lining materials, etc., must be complied with unless these cargo compartment(s) are not utilized and are placarded accordingly.
(Note: This Airworthiness Directive pertains only to the baggage and cargo-compartment fire-protection aspects of the above Regulation Amendments. Airworthiness Directives 49-19-1 and 49-18-1 have been issued covering fire protection for the powerplant installation and for the cabin-heater installation, respectively.)
(1) Lower Forward Cargo Compartment. When access provisions suitable for ready entrance by a crew member are available for use, the lower forward cargo compartment can be classified in the "B" category and as such must meet the requirements of CAR 4b. (It is recommended that a mask suitable for protecting a crew member from the effects of both smoke and fire-extinguishing agents be provided, since entry into the compartment will be a necessary part of any fire-fighting procedure.)
(Note: That portion of 4b requiring cargo-compartment fire-detection means need not presently be complied with.)
(2) Lower Rear Cargo Compartment. This compartment must be considered a "C" category compartment unless provisions suitable for ready entrance by a crew member are provided. As a "C" category compartment, compliance with CAR 4b must be shown. If the compartment is modified to provide suitable access, compliancewith the requirements of CAR 4b for a "B" category compartment must be demonstrated.
(Note: That portion of 4b requiring cargo-compartment fire-detection means need not presently be complied with.)
(3) It must be demonstrated that hazardous quantities of smoke or extinguishing agent cannot enter crew or passenger compartments as a result of a cargo-compartment fire. If the cargo compartment is determined to be in the "B" category, utilizing portable fire extinguishers, it is not necessary to test for excessive extinguishing agent concentrations. "C" category compartments protected by build-in, remotely operated fire extinguishing systems will necessitate tests to determine that hazardous quantities of the agent cannot enter crew or passenger-occupied areas. Crew and passenger compartment smoke evacuation procedures must be established.
Tests to determine smoke evacuation procedures, and, where necessary, to determine fire-extinguishing-agent concentrations in crew or passenger compartments, should simulate fire conditions as nearly as possible in flight. Where it can be established that the airplane is identical or sufficiently similar to others on which tests have been conducted, it will not be necessary to repeat these tests.
(Note: Carbon-dioxide concentrations in excess of 3 percent by volume in crew compartment are considered hazardous.)
(4) The provisions of Safety Regulation Release No. 259, "Compliance of Equipment and Materials Used in Air-Carrier Aircraft with Fire-Prevention Requirements," must be considered in demonstrating compliance with this directive.
(5) Airplane Flight Manual. Appropriate changes to the Airplane Flight Manual shall be prepared to cover the emergency procedures associated with cargo- and baggage-compartment fire control.

2011-15-05: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models B300 and B300C (C-12W) airplanes. This AD was prompted by an error found in the take-off speeds and field lengths published in the FAA-approved airplane flight manual. This AD requires a correction to the published data in the airplane flight manual and the pilot's operating handbook to ensure it corresponds with the published data in the pilot's checklist. This condition, if not corrected, could result in a pilot taking off from shorter runways than required by the airplane if the airplane loses an engine after takeoff decision speed (V1). This could result in the airplane running out of runway before take-off can be accomplished. We are issuing this AD to correct the unsafe condition on these products.
