Notice of proposed rulemaking (NPRM).

We propose to supersede Airworthiness Directive (AD) 2017-13- 03 for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. AD 2017-13-03 requires adding an identification number to life-limited rod ends that do not have a serial number (S/N). Since we issued AD 2017-13-03, an additional life-limited rod end was identified that is affected by the same unsafe condition. This proposed AD would retain the requirements of AD 2017-13-03 and revise the Applicability paragraph by adding that rod end. The actions of this proposed AD are intended to address an unsafe condition on these products.
