Airworthiness Directive · Amendment 39-9111 · Vickers-Armstrongs (Aircraft Limited) Airplanes
Vickers-Armstrongs (Aircraft Limited) Airplanes
This AD applies to Vickers-Armstrongs (Aircraft Limited) Viscount 744, Viscount 745D, Viscount 810.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model Viscount 744, 745D, and 810 series airplanes, that requires various inspections to detect damage, corrosion, or cracking of certain taper plugs and split bushings of the engine mount, and replacement of taper plugs or split bushings with serviceable parts, if necessary. This amendment is prompted by a report of damage of the taper plug and split bushing of the engine mount due to the effects of corrosion. The actions specified by this AD are intended to prevent such damage, which could lead to failure of the engine mount attachment assembly and consequent separation of the engine from the airplane.
