This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9, DC-9-80, and C-9 (military) series airplanes, and Model MD-88 airplanes. This proposal would require inspection to detect chafing on the FIREX pipe assembly of the number one engine; and either replacement of the chafed pipe assemblies with new pipe assemblies and modification of the FIREX and the pneumatic sense pipe assembly clamp marriage; or repair of the chafed pipe assemblies. This proposal is prompted by reports of incidents in which the pneumatic sense pipe chafed against the FIREX supply pipe of the number one engine. The actions specified by the proposed AD are intended to prevent the chafing of the FIREX supply pipe, which could result in a hole in the pipe and subsequently prevent the proper distribution of the fire extinguishing agent within the nacelle in the event of a fire.
