Airworthiness Directive · Amendment 39-11157 · British Aerospace Model BAC 1-11 200 and 400 Series Airplanes
British Aerospace Model BAC 1-11 200 and 400 Series Airplanes
All Model BAC 1-11 200 and 400 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model BAC 1-11 200 and 400 series airplanes, that requires an inspection to detect cracking of the flap control lever and to identify the material from which the lever is made; replacement of the flap control lever with an improved part, if necessary; and repetitive inspections for airplanes having a lever made from certain material. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the flap control lever, which could result in restricted flap movement and consequent reduced controllability of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
