Bell Helicopter Textron Canada Model 206A, 206A-1, 206B, 206B-1, 206L, 206L-1, 206L-3, and 206L-4 Helicopters

This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) model helicopters that requires performing a continuity test, temporarily repairing any unairworthy chip detector, and replacing any repaired chip detectors. This amendment is prompted by reports of poor or no continuity between the insert and the chip detector housing on certain chip detectors. The actions specified by this AD are intended to prevent failure of a chip detector indication, loss of a critical component, and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
