Airworthiness Directives; Cessna Model 750 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain Cessna Model 750 airplanes, that requires replacement of reset circuit breakers for the auxiliary hydraulic pump system and the King KHF 950 high frequency communication system(s) with new circuit breakers. This amendment is prompted by a report from the airplane manufacturer indicating that the trip levels for the reset circuit breakers installed in the auxiliary hydraulic pump system and the King KHF 950 high frequency system(s) are too high, which can prevent corresponding high current remote control circuit breakers from tripping when excessive electrical loads are present. The actions specified by this AD are intended to prevent overloading of the affected airplane electrical wiring and circuits, which could result in a fire.

Applicability paragraph with the specific airplane model/serial list was not present in the retrieved text; only the standard 'each airplane identified in the preceding applicability provision' boilerplate was captured. AD requires replacing 5.0-ampere reset circuit breakers (auxiliary hydraulic pump system and King KHF 950 HF comm system) with 0.5-ampere breakers per Cessna SB750-24-15 Rev 1 (SB number suggests Cessna Model 750/Citation X, not confirmed in text).

Whether AD 2002-23-05 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2002-23-05 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.
