Full official abstract
Airworthiness Directives; Various Aircraft Equipped With Wing Lift Struts
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain aircraft equipped with wing lift struts. The list of affected airplanes in the Applicability section is incorrect. Several Piper Aircraft, Inc. Model PA-18 airplanes were inadvertently omitted from the final rule; however, those models were included in the notice of proposed rulemaking. This document corrects that error. In all other respects, the original document remains the same.
This document corrects or clarifies a previously issued AD of the same number — it is not a separate, additional requirement. Its "Effective" date above may predate its own "Published" date because it restates the original AD's effective date.
