Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Beech (Raytheon) Model BAe 125-1000A and Model Hawker 1000 series airplanes. This proposal would require a one-time inspection for adequate clearances between, and damage to, the flap cables and turnbuckles, airbrakes cables and turnbuckles, and all other flight control cables and turnbuckles at keel subframe 15A; and various follow-on actions, if necessary. This proposal is prompted by reports of chafing due to insufficient clearance between the flaps turnbuckle and the subframe, and between the airbrakes cable and the subframe. The actions specified by the proposed AD are intended to prevent such chafing, which could result in damage to the flaps turnbuckle and the airbrakes cable, and subsequent fraying or seizing of the flight control cables. These conditions, if not corrected, could result in restriction or loss of the flight controls.
