Narrative:

Helicopter was in storage for 6 months. Helicopter was sold. I was helping put the helicopter in a container for shipping. When upon checking part number and serial number and components, it was discovered the serial number of the horizontal stabilizer was not the same as the aircraft paperwork. The serial number was almost impossible to read but you could tell it was not correct. The part had not been changed for about 4 yrs according to logbook. The owner has no idea what could have happened. The stabilizer is a time life item. Stabilizer will be removed by new owner, main rotor transmission serial number did not match paperwork. Owner remembers having the core changed for a crack and the identify plate was never changed. The paperwork, etc is being looked at by the people that originally overhauled the part and changed the case later. The write-up indicated a change in main rotor transmission. The internal gears are serialized and are being checked against the overhaul records. This will be settled and corrected by the new owners.
