Applies to All Models 1049C, D, E, G and H Airplanes. Compliance required by August 1, 1961, for items (a)(1) or (a)(2); July 1, 1961, for item (a)(3); and by September 30, 1960, for item (b). An accident occurred in which fire originating in the engine section burned underneath the nacelle and entered the wheel well area rupturing flammable fluid lines and causing extensive damage. An incident also occurred in which fire originating in the power section blistered the paint on the landing gear wheel well doors. An examination of the burn pattern on the landing gear doors indicated that the circumstances surrounding this incident were quite similar to those of the accident but with less severity due to the lower exposure time. To correct fire protection deficiencies in the wheel well area, the following modifications are considered necessary: (a) To prevent fire from entering the wheel well area, accomplish one of the following: (1) Replace the present aluminum skin on the forward landing gear doors with fireproof material. (2) Cover the present aluminum skin on the forward landing gear doors with fireproof material. (3) Coat both inside and outside of the present aluminum skin on the forward landing gear doors with a material that will withstand a flame of 2,000 degrees F. for 15 minutes. Product Techniques Inc. Coating PT-209, 0.015-inch thick on each side of the door is considered satisfactory when applied in accordance with PTI Process Specifications PTP 40-22. (b) Install fire sleeves over all flammable fluid-carrying flexible hose lines in zones 3 and 3A in the inboard engine nacelles. Revised May 4, 1960. Revised July 29, 1960.
