Airworthiness Directives; The Cessna Aircraft Company Model 525 (CitationJet 1) Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain The Cessna Aircraft Company (Cessna) Model 525 (CitationJet 1) airplanes. This AD requires you to replace certain direct current (DC) power battery switches. This AD is the result of reports of the potential for a certain 8-pole battery switch to fail during flight. The actions specified by this AD are intended to prevent this battery switch from failing while the airplane is in-flight, which is a latent failure. This could result in the pilot's inability to select "EMER" power or the inability to disconnect an overheated main ship's battery. On a battery overheat indication, the Airplane Flight Manual (AFM) instructs the pilot to disconnect the battery and, if the problem cannot be fixed, the pilot should immediately land the airplane. The main ship's battery that remains powered in an overheated condition may become hot enough to damage adjacent components and structure and may interfere with continued flight and a safe landing.

Serial-conditional — narrows to serials 525-0360–525-0400.

Part-conditional — A3-205-01/P.

Applies to Model 525 (CitationJet 1) airplanes, serial numbers 525-0360 through 525-0400, certificated in any category, that incorporate a DC power battery switch, Eaton P/N A3-205-01/P, with a manufacturer's date code of 9926 through 0039; requires inspection to determine whether the affected switch is installed, and if so, replacement with a new switch of the same part number having a date code of 0040 or later, or an FAA-approved equivalent part number, per Cessna Service Bulletin SB525-24-20, dated November 16, 2000; prohibits installing an affected switch on any airplane as of the effective date.

Whether AD 2001-02-13 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.

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.
