Plain English Summary

4/10 complexity

This AD mandates inspection and, where Bell Service Bulletin No. 206-50-73-2 prescribes, modification of rotor brake disc assembly P/N 4000071 on Bell/Agusta 206 helicopters fitted with rotor brake kit P/N 206-706-032-1. Operators and maintainers must follow the SB’s procedures to comply.
