AD NUMBER: 2012-10-09

PRODUCT: Piper Models PA-31T and PA-31T1 airplanes
SUBJECT: Airworthiness Directive 2012-10-09
ACTION: Final Rule

SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for the products listed above.

That AD currently requires correcting a model identification error on the aircraft data plate. Since that AD was issued, the FAA has become aware that some owner/operators of the affected airplanes modified the aircraft data plate in error because of confusion in the serial number applicability. Because of the confusion, the manufacturer has issued new service information to clarify affected airplane serial numbers.

This new AD requires determining the airplane model based on the serial number and modifying the aircraft data plate to properly identify the airplane model. This new AD also requires doing a detailed search for all applicable airworthiness related documents that apply to any airplane that has an incorrectly marked data plate and take necessary corrective actions based on the search findings.

DATES: This AD is effective June 29, 2012.
