## Summary

This document proposes the adoption of a new airworthiness directive (AD) applicable to Robinson Model R44 helicopters. The AD would require inspecting the wire harness for contact with the fuel line assembly, removing and replacing the fuel line assembly if chafing has occurred, and installing spiral wrap tubing on the fuel line assembly. This proposal is prompted by four incidents of contact between the wire harness and the fuel line assembly. The actions specified by the proposed AD are intended to prevent contact between the wire harness and the fuel line, which could result in chafing of the wire harness and a potential fire hazard.
