## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Jetstream Aircraft Limited (JAL) Jetstream Models 3101 and 3201 airplanes that have kit JK 2496 and modification JM 7537 installed. The proposed action would require installing magnetic latching relays on the ignition system. Reports of the auto-ignition system becoming disabled when switching from ground power to the airplane's internal power prompted the proposed action. The actions specified by the proposed AD are intended to prevent loss of the airplane's internal power connection to the auto-ignition system, which could cause loss of engine power and possible loss of the airplane.
