The FAA grounded the entire T-34 fleet after it discovered that cracks on the wing spar led to the crash of a Texas Air Aces T-34 earlier this month.
An Emergency AD, issued Dec. 10, grounds about 320 Beech A-34 and T-34 aircraft. The AD allows aircraft to be flown back to home base or a maintenance facility, but only in VFR conditions.
The crash this month, which killed two people, happened after the left wing came off the aircraft. According to the AD, the center section of the wing failed four inches inboard of the attach point. FAA investigators also found evidence of fatigue at other locations not covered by previous ADs.
The T-34 aircraft has had several wing failures in recent years, resulting in several wing spar airworthiness directives.
