Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Inc., Model 412, 412EP, and 412CF helicopters. This proposed AD was prompted by evaluation results showing flight loads that impact the collective lever fatigue life. This proposed AD would require adding a permanent life penalty for certain collective levers and prohibit installing those collective levers unless the permanent life penalty has been added. The FAA is proposing this AD to address the unsafe condition on these products.
