Airworthiness Directive · Amendment 39-9373 · 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 airplanes, that requires inspections to detect cracking of certain fittings of the tailplane spar, and replacement of the fittings with serviceable parts, if necessary. This amendment is prompted by reports of fatigue cracking of certain fittings in the tailplane spar. The actions specified by this AD are intended to prevent such cracking, which could result in structural degradation of the attachment of the horizontal stabilizer to the fuselage.
