Plain English Summary

1/10 complexity

What this does: This Airworthiness Directive (AD) mandates urgent safety work on specific agricultural aircraft. Owners and operators of Airtractor AT-300, 400, and 500 series aeroplanes (serial numbers 0001 to 0634) must inspect and repair the horizontal stabiliser eyebolts following the procedures set out in Snow Engineering Service Letter No. 62.

Who it affects: Anyone operating these specific aircraft models.

What must be done: The repair must be completed within 20 hours of flight time after 28 May 1986.

Why it matters: Several eyebolts that attach the strut to the horizontal stabiliser have failed. This is a critical structural component, and failure could lead to loss of aircraft control. This directive makes the repair legally mandatory (not optional) to prevent potentially catastrophic accidents.
