Bell Helicopter Textron Canada Model 430 Helicopters
Model 430 helicopters, serial numbers 49001 through 49059, certificated in any category.
Note 1: This AD applies to each helicopter identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For helicopters that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires calibration of the fuel quantity indicating system. This amendment is prompted by an operator report of an inaccurate fuel quantity indicating system. The actions specified by this AD are intended to prevent an inaccurate fuel quantity indicating system reading, engine flameout due to fuel starvation, and a subsequent forced landing.
To prevent an inaccurate fuel quantity indicating system reading, engine flameout due to fuel starvation, and a subsequent forced landing, accomplish the following:
(a) Calibrate the fuel quantity indicating system in accordance with steps 1 through 21 of the Accomplishment Instructions, Bell Helicopter Textron Alert Service Bulletin No. 430-99-13, dated December 13, 1999 (ASB).
(b) Insert BHT-430-MM-10, Chapter 95, Revision 2, dated December 10, 1999, into the Maintenance Manual.
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.
