The FAA has proposed an airworthiness directive requiring a one-time inspection of numerous Beechcraft King Air and Queen Air twin-engine aircraft models for fatigue cracking in lower forward wing fittings.
If inspection determines the presence of washer part number 90-380058-1 on the left-hand and right-hand lower forward wing bolt, further removal, inspection, and part-replacement actions would be required.
The FAA’s action was prompted by reports received by Textron Aviation, the current holder of the affected aircraft type certificates, of fatigue cracks in the lower forward wing fitting that could result in wing separation if not addressed, the AD said.
Comments on the AD may be submitted to the FAA until September 14 online or by mail to U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. Include “Docket No. FAA-2020-0718; Product Identifier 2019-CE-041-AD” at the beginning of your comments.
