BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited BAe 146-100A, BAe 146-200A, BAe 146-300A.
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 certain Avro Model BAe 146 series airplanes. This action requires inspections to detect cracking and damage of the fastener holes in the butt strap at rib 2 at the lower surface of the right-hand wing; repair of discrepancies; and replacement of the fastener bolts. This amendment is prompted by a report that certain wings were manufactured with a reduction in the amount of edge margin between the fastener hole centers and the edge of the butt strap; this condition can result in a decrease in the long-term damage tolerance residual strength of the wing. The actions specified in this AD are intended to prevent cracking and other problems associated with a such decrease in the long-term damage tolerance residual strength of the wing.
