N4712R

On March 1, 1994, about 0830 hours Pacific standard time, a Bell 206A helicopter, N4712R, disappeared at sea under unknown circumstances in international waters at north latitude 17 degrees 56 minutes by west longitude 109 degrees 46 minutes. The helicopter, operated by L & M Offshore Corporation of Paitilla, Republic of Panama, was engaged in fish spotting operations from the Mexico registered tuna vessel, "El Quijote." Visual meteorological conditions prevailed at the time and a flight plan was filed with the ship. The helicopter is presumed to have been destroyed in the accident sequence. Both the pilot and the spotter on board the helicopter sustained fatal injuries. The flight originated from the ship on the day of the mishap at about 0730 hours as a local fish spotting mission.

According to a report from the operator, the helicopter had completed the assigned spotting mission and was returning to the ship when it disappeared from the ship's radar about 3 miles short of the vessel. There were no known distress calls prior to the disappearance. A search of the area around the last known position of the helicopter revealed parts of an emergency float system known to have been installed on the helicopter, and the bodies of the pilot and spotter. No trace of additional aircraft components were found.

The pilot was a Panamanian citizen who reportedly held a pilot certificate issued by the Republic of Panama. The fish spotter was a Mexican national who has not been identified.
