Airworthiness Directives; Beech Model BAe 125-1000A and Hawker 1000 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Beech Model BAe 125-1000A and Hawker 1000 series airplanes, that requires a detailed visual inspection to detect chafing damage to the hydraulic pipes adjacent to the hydraulic module, and various follow-on actions. This amendment is prompted by reports of chafing damage between hydraulic pipes at three locations in the rear equipment bay adjacent to the hydraulic module. The actions specified by this AD are intended to prevent such chafing damage to the hydraulic pipe and subsequent hydraulic fluid leakage, which could lead to failure of essential airplane systems.
