Summary
This document proposes the adoption of a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters. This proposal would require calibration of the fuel quantity indicating system. This proposal is prompted by an operator report of an inaccurate fuel quantity indicating system. The actions specified by the proposed AD are intended to prevent an inaccurate fuel quantity indicating system reading, engine flameout due to fuel starvation, and a subsequent forced landing.
