Summary
We propose to adopt a new airworthiness directive (AD) for certain Taylorcraft Models A, B, and F series airplanes. This proposed AD would require inspection of the wing strut attach fittings for corrosion or cracks and would require repair or replacement if corrosion or cracks are found. This proposed AD results from data collected from an accident involving a Taylorcraft Model BF12-65 airplane. The wing separated from the airplane after the wing strut attach fitting failed due to corrosion. We are proposing this AD to detect and correct corrosion or cracks in the wing strut attach fittings. This condition, if not corrected, could result in failure of the wing strut attach fittings and lead to wing separation and loss of control.
