AD 99-16-06 64 FR 42275

This amendment adopts a new airworthiness directive (AD) that applies to certain The New Piper Aircraft, Inc. (Piper) Model PA-46- 350P airplanes. This AD requires installing reinforcement plates to the wing forward and aft attach fittings. This AD is the result of a report that sheet steel material that is below design strength standards may have been utilized on the wing attach fittings on the Model PA-46-350P airplanes manufactured since January 1995. The actions specified by this AD are intended to prevent structural failure of the wing attach fittings caused by the utilization of substandard material, which could result in the wing separating from the airplane with consequent loss of control.
