Airworthiness Directive · Amendment 39-19557 · Landing gear system
Bell Helicopter Textron Canada Limited Helicopters
This AD applies to Bell Helicopter Textron Canada Limited Model 429 helicopters with a nose landing gear (NLG) assembly part number (P/N) 429-336-100-101 installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. This AD revises the life limit for the nose landing gear (NLG) assembly. This AD was prompted by revised airworthiness limitations determined by Bell. The actions of this AD are intended to prevent an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Before further flight, remove from service any NLG assembly P/N 429-336-100-101 that has reached or exceeded 4,500 hours time-in-service (TIS) or 50,000 retirement index number (RIN). Thereafter, remove from service each NLG assembly P/N 429-336-100-101 before accumulating 4,500 hours TIS or 50,000 RIN, whichever occurs first. For purposes of this AD, for every normal retraction or extension of the wheeled landing gear system, add one RIN.
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.
