Airworthiness Directive · Amendment 39-18933 · Standard practices/structures
Bell Helicopter Textron Canada Limited Helicopters
Superseded. A later AD replaced this one: AD 2018-21-15. Comply with the one in force.
This AD applies to Model 429 helicopters, serial number 57001 through 57260, with a pylon restraint spring assembly (spring assembly) forward rod end (rod end) part number (P/N) 427-010-210-105 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 requires adding an identification number to life-limited rod ends that do not have a serial number (S/N). The actions of this AD are intended to address 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.
(1) Within 140 hours time-in-service, clean and identify each forward rod end with the spring assembly serial number in accordance with the Accomplishment Instructions, paragraphs 3 through 5, and 7 through 8, of Bell Helicopter Alert Service Bulletin 429-15-19, dated February 26, 2015.
(2) Do not install a forward rod end P/N 427-010-210-105 on any helicopter unless it has been marked with a serial number in accordance with paragraph (e)(1) of this AD.
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.
