with a
           ¼-inch thick vertical fin front spar fitting installed from the applicability of AD 95- 20-06 (AD/AT/17 refers), due to reports indicating that only 3/16- inch fittings were affected. Recently a Model AT-502 aircraft was found with a cracked ¼- inch thick vertical fin front spar fitting. The crack was found during a routine inspection. The rear spar had not yet failed. This recent finding demonstrates that Air Tractor models with a ¼-inch thick vertical fin front spar fitting are subject to fatigue failure.
