Airworthiness Directive · Amendment 39-8819 · Viking Air Limited Airplanes
Viking Air Limited Airplanes
This AD applies to Viking Air Limited DHC-6-1, DHC-6-100, DHC-6-200, DHC-6-300.
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 supersedes two existing airworthiness directives (AD's) that currently require repetitively inspecting the wing attachment fittings and the wing front fittings for cracks on certain de Havilland DHC-6 series airplanes, and replacing any cracked part. The Federal Aviation Administration's policy on aging commuter class aircraft is to eliminate or, in certain instances, reduce the number of repetitions of certain short-interval inspections when improved parts or modifications are available. This action requires incorporating a modification that would eliminate the need for the repetitive inspections currently required by the two existing AD's. The actions specified by this AD are intended to prevent loss of control of the airplane caused by cracked wing attachment fittings.
