Airworthiness Directive · Amendment 39-8971 · 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 adopts a new airworthiness directive (AD) that applies to de Havilland DHC-6 series airplanes. This action requires repetitively inspecting the horizontal stabilizer center hinge bracket for cracks, and replacing any cracked center hinge bracket. Several reports of cracks in the horizontal stabilizer center hinge bracket flange on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent separation of the elevator control support from the airplane as a result of a cracked horizontal stabilizer center hinge bracket, which could result in reduced controllability of the airplane.
