AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Visually inspect the junction frame area for a crack, paying particular attention to the area around the 4 spars. If there is a crack, replace or repair the junction frame in accordance with an FAA approved repair procedure before further flight. Repairing the junction frame would not constitute terminating action for the requirements of this AD. For helicopters with MOD 074775 installed or with the four carbon patches reinforcements installed, visually inspect the junction frame area for a crack within 600 hours TIS after the installation of MOD 074775 or the reinforcement, and thereafter at intervals not exceeding 600 hours TIS. If there is a crack, replace or repair the junction frame in accordance with an FAA approved repair procedure before further flight.

Also, within 150 hours TIS and thereafter at intervals not to exceed 150 hours TIS, repeating the initial visual inspection.
