## Summary

We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (Bell) Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, and 407 helicopters. This proposed AD would require inspecting and cleaning the oil supply restrictor (restrictor) to the freewheel assembly. This proposed AD is prompted by reports of a blocked oil line restrictor in the freewheel lubrication system. The proposed actions are intended to address an unsafe condition on these products.
