Posted by Clinton McJenkin on May 24th 2024

FAA AD Number: 2024-10-04 has been issued for a problem identified is a double-drilled bolt hole in the rear wing spar attachment fitting, discovered during an inspection after a ground collision with an automobile. This problem reduces the strength of the part below its limit load, potentially leading to wing separation and loss of control of the airplane.

It is crucial to follow the specified corrective actions as detailed in Piper Service Bulletin No.1413. These actions include removing the wing fastening hardware, conducting a thorough inspection, and taking necessary corrective measures. If any discrepancies are found, an additional inspection of bolt holes common to the forward spar attachment is required, with components replaced if necessary. Additionally, a report must be submitted to the FAA if corrective actions or replacement is necessary.


This report pertains to certain serial-numbered Piper Model PA-28-181 Piper Archer, PA-28R-201 Piper Arrow III, PA-34-220T Seneca V, and PA-44-180 Piper Seminole airplanes.

Additionally, any components with bolt holes that exceed specified limits need to be replaced before further flight.


ATA code 5741 is generally related to "Flap Position Sensing System" in aircraft. This ATA code pertains to the system responsible for sensing and indicating the position of the flaps on an aircraft. The Flap Position Sensing System is crucial for providing accurate information to the flight crew regarding the position of the flaps during takeoff, landing, and other phases of flight. It is part of the overall flap system that helps control the lift and drag characteristics of the aircraft during different flight conditions.
