## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Model BAe.125 series 800A (including C-29A and U-125 Variant) and 800B airplanes; and Model Hawker 800 (including U-125A Variant) and 800XP airplanes. This proposal would require a functional test of the engine fire extinguishing wiring for the appropriate installation; verification of the correct wiring connector installation; correction of wiring if necessary; and installation of new marker bands. This action is necessary to prevent incorrect wiring of the engine fire extinguisher bottles, which could result in one or both fire extinguisher bottles being discharged into the wrong engine nacelle. This action is intended to address the identified unsafe condition.
