## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Aerospatiale Model ATR42 series airplanes. This proposal would require removal of certain landing gear attachment pins, and replacement of the pins with serviceable pins. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent wear of the attachment pins, which could result in collapse of the main landing gear.
