Lockheed P-3 Orion

Air tanker N924AU had been dispatched from its base in Santa Barbara, CA to Missoula, MT to support fire suppression efforts involving a number of large fires in the Northern Region. The flight departed in VFR conditions at 16:05 PDT. While still in the area controlled by the Oakland FAA Air Route Traffic Control Center (ARTCC), the crew requested and received an Instrument Flight Rules (IFR) clearance. They were assigned an altitude of 23,000 feet. The Orion proceeded uneventfully and was handed off to the Approach Controller at Missoula (MSO). MSO Approach did not have, at that time, terminal radar equipment that covered their entire area of responsibility. At first contact with MSO Approach, the Orion was 26 miles southeast of the Missoula International Airport and descending to 12,000 feet. In the course of several exchanges between the Orion and the MSO Approach Controller, it was disclosed and confirmed that the Orion’s flight crew did not have the approach plate (or chart) depicting the published approach procedure for the VOR-DME Bravo (B) approach, which was the approach in use for aircraft arriving from the south. Clearance was nevertheless offered and accepted and the controller provided the information as the Orion crew began to execute the VOR-DME B approach. At this time, the cloud bases at the MSO Airport were at about 7,900 feet and other aircraft making instrument approaches there were descending through 8,000 feet, cancelling their IFR flight plans and making visual approaches to the airport for landing. Since the Orion’s crew was able to monitor these radio communications/transmissions on the same frequency, they were probably counting on doing the same. At this time, there were very strong winds and moderate to severe turbulence reported at altitudes above 8,000 feet that increased with altitude in the MSO area. In addition to turbulence, the Orion crew contended with effects of flying at high altitudes, using oxygen in an unheated and un-pressurized aircraft for more than two hours. At some point in the initial phase of the approach, some confusion as to what heading to fly apparently occurred and the airtanker turned back toward the south, away from MSO. By this time the controller had authorized descent to 8,600 feet on an approximate heading of 200 degrees magnetic. MSO Approach received notification by Salt Lake City ARTCC (Center) that this airtanker was west of the course consistent with the approach procedure and subsequent notification that the airtanker had disappeared off Center’s radar screen. Repeated attempts to contact the Orion crew failed and MSO Approach notified the County Sheriff’s office, the Forest Service, and other agencies that the aircraft was missing and presumed down. Search and rescue attempts were not able to detect an Emergency Locator Transmitter (ELT) signal. The mishap site was located the following day.

The aircraft was engaged in a local flight and was carrying 17 passengers and a crew of four. After takeoff from Cocos Island Airport, the crew climbed to 5,000 feet then reduced his altitude for a low pass over the airport. Approaching the airport at a speed of 380 knots and at a height of about 300 feet, the pilot-in-command increased engine power in a way to gain height when the aircraft lost several pieces from the left wing. Due to severe vibrations and problems of controllability, the crew decided to attempt an emergency landing near the airport. The aircraft struck the ground, lost its undercarriage and came to rest in shallow water. A passenger was killed after being hit by propeller blades that punctured the fuselage. All 20 other occupants escaped uninjured and the aircraft was damaged beyond repair.

The aircraft departed Moffett AFB on a combined survey mission over the Pacific Ocean with a second USN Orion registered 159325 carrying a crew of 13. While cruising at an altitude of 3,000 feet in marginal weather conditions, both aircraft collided and crashed in the sea. Few debris were found floating on water about 60 miles southwest of San Diego and all 27 crew members were missing and never recovered.

The crew was taking part to an airshow at Crows Landing-Aux Field AFB and practicing touch-and-go. For unknown reasons, the aircraft landed hard, went out of control and came to rest, bursting into flames. All four crew members escaped uninjured while the aircraft was destroyed.

For unknown reasons, the aircraft landed hard at Whidbey Island NAS and was considered as damaged beyond repair. There were no casualties.

Crashed in unknown circumstances while approaching an airport somewhere in Iran. Occupant fate unknown. The accident occurred somewhere in February 1985 (exact date unknown).

The four engine airplane departed Barbers Point NAS on a night training exercise consisting of a support of ships cruising off Kauai Island. While cruising in limited visibility at an altitude of 3,000 feet, the aircraft struck the slope of a mountain and disintegrated on impact. The wreckage was found on a steep ridge (Kalepa Ridge between Honopu and Kalalau valleys) on the Na Pali Coast of Kauai. All 14 occupants were killed. The pilot failed to realize his altitude was insufficient and did not see the mountain.

For unknown reasons, the four engine airplane landed on its belly at Barbers Point NAS. It slid for few dozen yards then veered off runway and came to rest, bursting into flames. All occupants escaped uninjured while the aircraft was damaged beyond repair.

While conducting a Naval Air Training and Operating Procedures Standardization check the pilot at controls was allowed to perform his first attempt at shooting an obstacle approach at Whidbey Island NAS. This maneuver was inadequately briefed by the pilot in command during the mission brief. The pilot in command, having great confidence in the pilot at controls, allowed him to conduct this maneuver without prior demonstration. After pushing over for the approach an excessive sink rate developed. Upon determination that the approach was getting dangerous, power was applied and the nose pulled up. Due to the combination of slow approach speed, late and in inadequate power application, the excessive sink rate was not arrested, resulting in a hard landing followed by failure of the starboard wing.
