Abstract
The FAA is adopting a new airworthiness directive (AD) for all Bell Textron Inc. (Type Certificate previously held by Bell Helicopter Textron Inc.) Model 412, 412CF, and 412EP helicopters. This AD requires revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. This AD was prompted by an accident and multiple reports of a cracked main gearbox (MGB) support case. The FAA is issuing this AD to address the unsafe condition on these products.
