Airworthiness Directive 00-23208
one-timeAirworthiness Directives; Bell Helicopter Textron, Inc. Model 412, 412EP, and 412CF Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron, Inc. (BHTI) Model 412, 412EP, and 412CF helicopters. This AD requires inspecting the upper left-hand cap angle (cap angle) and adjacent structure for a crack and, before further flight, replacing any cracked cap angle and repairing any crack in the adjacent structure. This AD is prompted by a report of a fatigue crack in a tailboom attachment cap angle. The actions specified in this AD are intended to prevent failure of a cap angle, loss of the tailboom, and subsequent loss of control of the helicopter.
Which aircraft AD 00-23208 applies to
Requires recurring inspection of the tailboom cap angle and adjacent structure for cracks per Bell Helicopter Textron ASB 412-00-100, with any crack found reported to the Rotorcraft Certification Office within 10 days. Model family (412) inferred from Bell ASB numbering convention.
Whether AD 00-23208 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.
