            Applicability: Boeing 737-300, -400, and -500 series aircraft with line numbers 2137 through 2271 inclusive.

             Requirement: 1. Inspect the inner wall of the thrust reverser fan duct cowl in accordance with Boeing Alert Service Bulletin 737-78A1056 to determine if the correct firewall insulation topcoat material is present and rectify as required.

            Note: FAA AD 95-09-01 also refers.

             Compliance: 1. Unless previously accomplished, at next "C" check but no later than 31 December 1996.

            Background: Boeing has advised that a change to the fireproof insulation on the thrust reverser fan duct firewall to decrease aircraft weight has resulted in the firewall not meeting certification requirements.
