## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-10-10, -15, -30, and -40 series airplanes. This proposal would require installation of a new protector cap in all fuel tank boost/ transfer pump housings. This proposal is prompted by reports of inoperative fuel boost/transfer pumps due to arcing or burning of the electrical connector. The actions specified by the proposed AD are intended to prevent damage to the fuel tank boost/transfer pump housings in case of an electrical connector malfunction, which could result in increased risk of a fuel tank explosion or fire.
