Airworthiness Directive 00-23730
one-timeAirworthiness Directives; Raytheon Aircraft Company Beech Models 1900C, 1900C (C-12J), and 1900D Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Models 1900C, 1900C (C-12J), and 1900D airplanes. This AD requires you to install a spiral wrap around the wing fuel quantity wiring harness and apply an adhesive sealant to the Wiggins couplings on the internal fuel tank wiring carry-through conduit. This AD is the result of reports of chafed or shorted wing fuel quantity harness wires on the affected airplanes. These occurrences were found during regular maintenance inspections. The actions specified by this AD are intended to prevent chafing between the wing fuel quantity wiring harness and the internal wing harness supports at each wing rib location, which could cause the fuel quantity indication to become unreliable. This could leave the flight crew without an indication of the amount of fuel the airplane has during flight. The actions are also intended to prevent fuel from leaking through the wiring carry-through conduit and into the wing tip or wheel well area, which could lead to a fire or explosion.
Which aircraft AD 00-23730 applies to
Two-part AD, certificated in any category. Part I (wing fuel quantity wiring harness attachment): 1900C S/N UC-1 through UC-174; 1900C (C-12J) S/N UD-1 through UD-6; 1900D S/N UE-1 through UE-331. Part II (Wiggins coupling adhesive sealing): same 1900C/C-12J ranges; 1900D S/N UE-1 through UE-354.
Whether AD 00-23730 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.
