Airworthiness Directives: Rolls-Royce Corporation (formerly Allison Engine Company) 250-C20 Series Turboshaft and 250-B17 Series Turboprop Engines, Correction

What this AD requires

This document makes a correction to Airworthiness Directive (AD) 2001-24-12 applicable to Rolls-Royce Corporation (formerly Allison Engine Company) 250-C20 series turboshaft and 250-B17 series turboprop engines, that was published in the Federal Register on December 4, 2001 (66 FR 62915). The AD number being superseded was inadvertently omitted under the PART 39--AIRWORTHINESS DIRECTIVES amendatory instruction 2 in the heading of the AD. This document corrects that omission. In all other respects, the original document remains the same.

Which aircraft AD 2001-24-12 applies to

MakesAirworthiness Directives: Rolls-Royce Corporation (Formerly Allison Engine Company) 250-C20

Whether AD 2001-24-12 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 2001-24-12 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.
