Airworthiness Directive 97-22146
one-timeAirworthiness Directives; Raytheon Aircraft Company Model 1900D Airplanes (Formerly Known as Beech Aircraft Corporation Model 1900D Airplanes)
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Raytheon Aircraft Company (Raytheon) Model 1900D airplanes (formerly known as Beech Aircraft Corporation Model 1900D airplanes) that have not had the propeller removed and re-installed since factory installation. This action requires inspecting the propeller mounting bolts for the proper torque and replacing or re- torquing any propeller bolt with the wrong torque level. The manufacturer discovered some under-torqued propeller mounting bolts during factory installation of the propeller. The actions specified by this AD are intended to prevent fatigue cracking and failure of the propeller mounting bolts, which if not detected and corrected, could result in loss of the propeller.
Which aircraft AD 97-22146 applies to
Propeller mounting bolt (P/N B3347) fatigue-cracking AD for Model 1900D. Action depends on whether the propeller has been removed/reinstalled since factory installation: if not, check bolt torque and either replace (if <60 ft-lb) or re-torque to 100-105 ft-lb, per Model 1900D Maintenance Manual 61-10-00.
Whether AD 97-22146 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.
