Airworthiness Directive 2002-23-05
one-timeAirworthiness 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.
Which aircraft AD 2002-23-05 applies to
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:
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.
