Plain English Summary

2/10 complexity

This directive requires owners/operators of specified Mitsubishi MU-2 models/serial numbers to have the elevator trim indicator scale dial physically modified exactly per Mitsubishi Service Bulletin No. 228, to align the indicator with the reduced elevator trim range imposed by an earlier AD.

The work is mandatory, must be completed within 100 hours TIS from the effective date, and is at the operator’s expense, imposing technical, labour and downtime costs.
