Airworthiness Directive 2001-20-07
one-timeAirworthiness Directives; Raytheon Model Beech 400A Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon (Beech) Model 400A series airplanes, that requires replacement of certain bus bars connecting the battery and external power receptacle to the airframe ground with a new, improved bus bar. This amendment is prompted by reports of electrical arcing at the battery and external power receptacle of the airframe ground in the aft fuselage due to a deficiency in the bus bar and washer design. The actions specified by this AD are intended to prevent overheating or arcing of the ground connection in the aft fuselage area, which could result in a fire hazard due to ignition of fuel fumes during an engine start sequence.
Which aircraft AD 2001-20-07 applies to
Applies to Raytheon (Beech) Model 400A series airplanes; replace bus bars P/N 128-364239-17 and P/N 101-361146-1 with new, improved bus bar P/N 101-364046-231 per Raytheon Aircraft SB 24-3253, dated January 1999, to prevent electrical arcing/overheating of the ground connection in the aft fuselage.
Whether AD 2001-20-07 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.
