Plain English Summary

1/10 complexity

This Airworthiness Directive (a mandatory safety order from the aviation regulator) requires specific Mooney aircraft owners to fix a structural problem with the main landing gear.

What it does: Forces owners to modify the main landing gear retraction truss (the metal framework that holds the wheels and folds them into the fuselage) according to the manufacturer's Service Bulletin M20-143.

Who must comply:

Mooney M20C aircraft with serial numbers 2807 to 3466
Mooney M20E aircraft with serial numbers 470 to 1270

Deadline: Within 100 hours of flight time after 7 September 1967 (note: this is a historical directive from 1967).

Why it exists: To prevent structural failure of the landing gear system during operation, which could cause a crash during landing or gear retraction.
