FAA ISSUES PROPOSED RULE ABOUT AIRWORTHINESS DIRECTIVES

WASHINGTON, Nov. 21 -- Federal Aviation Administration has issued a proposed rule called: Airworthiness Directives; The Boeing Company Airplanes.

The proposed rule, published in the Federal Register on Nov. 18 by Kalene C. Yanamura, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service, states: "We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD would require inspecting to detect damage to the upper fire seals on the forward edge of the thrust reverser, where the fire seal contacts the 12-o'clock engine strut, and for correct stiffness and vent holes, and doing corrective actions if necessary; and installing a bracket for the fire seal. This proposed AD was prompted by reports of damaged fire seals on the forward edge of the thrust reverser. We are proposing this AD to detect and correct damage to the fire seals, which could result in damage to the strut structure and the thrust reverser firewall. Such damage could significantly deteriorate the protection capacity of the fire extinguishing system and result in an uncontrolled fire."
