Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-90-30 series airplanes. This proposal would require modification of the wiring of the strake ice protection system (SIPS). This proposal is prompted by a report of a fire in the electrical and electronic compartment of a Model MD-90-30 series airplane. The actions specified by the proposed AD are intended to prevent an electrical short circuit of the wiring of the SIPS, which could result in a fire in the electrical and electronic compartment of the airplane.
