Airworthiness Directives; Teledyne Continental Motors IO-360, TSIO-360, LTSIO-360, IO-520, LIO-520, TSIO-520, LTSIO-520 Series, and Rolls-Royce plc IO-360 and TSIO-360 Series Reciprocating Engines; Correction

What this AD requires

This document makes a correction to airworthiness directive (AD) 97-26-17 applicable to certain Teledyne Continental Motors (TCM) IO-520 and TSIO-520 engines that was published in the Federal Register on December 19, 1997 (62 FR 66502). The address information for the contact engineer in the For Further Information Contact section and the manufacturer's telephone number in the Addresses section and paragraph (f) of the Compliance Section is incorrect. This document corrects that information. In all other respects, the original document remains the same.

Whether AD 98-5798 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 98-5798 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.
