Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Beech (Raytheon) Model BAe 125-800A, Model Hawker 800, and Model Hawker 800XP series airplanes. This proposal would require the filling of two tooling holes on the firewalls of the left and right engine pylons with sealant. This proposal is prompted by notification from the manufacturer that these holes were not sealed during production. The actions specified by the proposed AD are intended to prevent an engine fire from moving to the fuselage and to the lines that carry flammable fluid that are located inboard of the firewall.
