Plain English Summary

2/10 complexity

The Civil Aviation Safety Authority’s Part 39 directive requires owners/operators of specified Maule M‑4 serial numbers to inspect and carry out the modification in Maule Aircraft Corporation Service Bulletin No. 1 on the fuselage front attach tube that supports the horizontal tail, within 100 hours TIS after 31 October 1979 (unless already done).

It affects those M‑4 owners/operators, shifts cost and scheduling burden to them, and aims to mitigate the risk of a potentially cracked attach tube.
