## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B airplanes, that would have required modification of the hot detection system of the tail pipe harness of the engine nacelles. This new action revises the original NPRM by reducing the compliance time for the modification and adding repetitive inspections. The actions specified by this new proposed AD are intended to prevent false warning indications to the flightcrew from the hot detection system due to discrepancies of the harness, which could result in unnecessary aborted takeoffs on the ground or an in-flight engine shutdown. This action is intended to address the identified unsafe condition.
