Descripción:
The P-3 Orion aircraft departed at 08:36 on a ship surveillance mission. Approximately two hours after takeoff the aircraft reported all systems essential to the mission were operating normally. No further radio contact was made. At 11:20 the aircraft struck a mountain on a small island named El Hierro, at an altitude of 2300 ft msl. The top of the mountain was at 5200 ft msl. Visibility at the crash site was 50 meters in rain. The aircraft impacted in level flight at 220 knots. All engines were operating, except for #1, which was shutdown for loiter.
The PPC, navigator, radar operator and flight engineer were at the NCO club until 02:00 local, consuming alcoholic beverages. The post mortem showed that the navigator had experienced a myocardial infarction.
The island was located inside the northwest corner of the assigned patrol area. It is very possible that the crew was unaware of the island.

Probable Cause:

PROBABLE CAUSE FACTORS:
Flight crew - violation of natops regarding alcohol consumption/crew rest prior to flight.
Supervisory/squadron - failure to implement an effective aircrew surveillance program.

CONTRIBUTORY FACTOR:
Flight crew complacency - nonadherence to sound navigation procedures.

POSSIBLE CAUSE FACTOR:
TSC briefing display omission of the three Canary Islands.
Weather conditions - fog and rain.
