Airworthiness Directives; Textron Lycoming O-360, LO-360, HO-360, HIO-360, TIO-360, LIO-360, AEIO-360, O-540, IO-540, TIO-540, LTIO-540, IVO-540, AEIO-540, TIO-541, and IO-720 Series Reciprocating Engines

What this AD requires

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 95-07-01 that was sent previously to all known U.S. owners and operators of Textron Lycoming O-360, LO- 360, HO-360, HIO-360, TIO-360, LIO-360, AEIO-360, O-540, IO-540, TIO- 540, LTIO-540, IVO-540, AEIO-540, TIO-541, and IO-720 series reciprocating engines by individual letters. This AD requires removal prior to further flight of suspect unapproved connecting rod bolts and replacement with serviceable connecting rod bolts. This amendment is prompted by reports of connecting rod bolt failures. The actions specified by this AD are intended to prevent engine failure due to connecting rod bolt failure, which could result in damage to or loss of the aircraft.

Applies only to engines assembled on or after February 15, 1994 that contain connecting rod bolts shipped directly or indirectly from Superior Air Parts, Inc. on or after February 15, 1994.

Whether AD 95-7683 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 95-7683 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
