Full official abstract
This document publishes in the Federal Register an amendment adopting emergency Airworthiness Directive (AD) 2000-14-51. The Federal Aviation Administration (FAA) previously sent emergency AD 2000-14-51 to all known U.S. owners and operators of Air Tractor Models AT-501, AT-502, and AT-502A airplanes. This AD requires you to inspect the wing lower spar cap for cracks and modify or replace any cracked lower spar cap. This AD is the result of an accident report of an Air Tractor Model AT-502A airplane where the wing separated in flight. The actions specified by this AD are intended to detect and correct fatigue cracks in the wing lower spar cap, which could result in an in-flight separation of the wing from the airplane.
