## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes equipped with Pacific Scientific engine fire extinguisher bottles. This proposal would require a one-time inspection to detect discrepancies in the wiring installation of the engine fire extinguisher bottles, and related investigative/corrective actions as necessary. This action is necessary to prevent the inability of the left-hand fire extinguisher on one or more engines to discharge, and consequent inability to control or suppress an engine fire. This action is intended to address the identified unsafe condition.
