The Federal Aviation Administration issuing AD - Continental and Superior Air Parts (2024)

The FAA is adopting a new airworthiness directive (AD)for certain Continental Aerospace Technologies, Inc. (Continental) GTSIO-520, IO-470, IO-520, IO-550, IOF-550, LIO-470, LIO-520, LTSIO-520, O-470, TSIO-470, TSIO-520, TSIO-550, TSIOF-550, and TSIOL-550 model reciprocating engines with a certain Superior Air Parts, Inc. (SAP) cylinder assembly or intake valve installed.

The affected cylinder assemblies and intake valves are installed as a replacement part under parts manufacturer approval (PMA) on certain affected Continental engines. This AD was prompted by three intake valve failures on reciprocating engines that resulted in engine damage and emergency landing or aborted takeoff. This AD requires replacement of the affected engine intake valve. The FAA is issuing this AD to address the unsafe condition on these products.

This AD is effective February 17, 2023.

The FAA must receive comments on this AD by March 20, 2023.

You may send comments, using the procedures found in14 CFR 11.43and11.45, by any of the following methods:

•Federal eRulemaking Portal:Go toregulations.gov.Follow the instructions for submitting comments.

•Fax:(202) 493-2251.

•Mail:U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590.

•Hand Delivery:Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Justification for Immediate Adoption and Determination of the Effective Date

Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for “good cause,” finds that those procedures are “impracticable, unnecessary, or contrary to the public interest.” Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause.

The FAA is issuing this AD because the agency has determined the unsafe condition described above is likely to exist or develop in other products of the same type design.
