After two incidents involving faulty factory work on Piper aircraft, the FAA has proposed that owners of piston-powered Piper-built aircraft have their right and left control columns inspected and repaired, if necessary. In one of the incidents, the right-hand control wheel on a Seneca broke off due to a mis-drilled hole in the column at the universal joint, and in the other, a ground inspection of a Seneca revealed a similar problem on the left control wheel.
