This AD requires determining the total hours time-in-service (TIS) of certain part-numbered TR blades, establishing a life limit for certain part-numbered TR blades, removing from service any TR blade that has reached or exceeded its life limit, creating a component history card, re-identifying certain part-numbered TR blades, and removing any TR blade from service before reaching its retirement life. This AD also prohibits installing certain TR blades on certain model helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
