## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Overland Aviation Services fire extinguishing system bottle cartridges that were distributed during a certain time period. The proposed AD would require removing from service any of these fire extinguishing system bottle cartridges. The proposed AD is the result of several incidents where the fire extinguishing system bottle cartridges activated with excessive energetic force. In one instance, the discharge valve outlet screen fractured and the screen material went through the distribution manifold. The actions specified by the proposed AD are intended to prevent damage to fire extinguishing system components caused by a fire extinguishing system bottle cartridge activating with excessive energetic force, which could result in the fire extinguishing system operating improperly.
