Summary
The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) Model 206L, 206L-1, 206L-3, and 206L-4 helicopters with a certain part-numbered main rotor (M/R) blade installed under Supplemental Type Certificate (STC) SR02684LA. This proposed AD was prompted by delamination of M/R blades. This proposed AD would require a repetitive inspection for delamination, and depending on the results, removing the M/R blade from service and reporting certain information. The FAA is proposing this AD to address the unsafe condition on these products.
