The FAA issued a new airworthiness directive (AD) for specific Piper aircraft models after an unscheduled inspection, prompted by a ground collision with an automobile, revealed a double-drilled bolt hole in the rear wing spar attachment fitting.
The FAA says the AD will affect some 500 U.S.-registered aircraft—including certain serial-numbered Piper models PA-28-181, PA-28R-201, PA-34-220T, and PA-44-180. It requires inspection of the rear wing spar attachment fitting and, if discrepancies are found, inspecting the forward wing spar attachment fitting as well. The directive mandates performing necessary corrective actions and notifying the FAA once these actions have been completed.
