Adak

According to the pilot, when the airplane’s airspeed reached about 90 knots during the takeoff roll, he applied back pressure to the control yoke to initiate the takeoff and noted a brief positive rate of climb followed by a sinking sensation. The airspeed rapidly decayed, and the stall warning horn sounded. To correct for the decaying airspeed, he lowered the nose then pulled back on the airplane’s control yoke and leveled the wings just before impacting the ocean. The pilot stated there were no pre accident mechanical malfunctions or anomalies that would have precluded normal operation. Wind about the time of the accident was recorded as 110º downwind of the airplane at 15 knots gusting to 28 knots. The passengers recalled that the pilot’s preflight briefing mentioned the downwind takeoff but included no discussion of the potential effect of the wind conditions on the takeoff. The airplane’s estimated gross weight at the time of the accident was about 769.6 pounds over its approved maximum gross weight, and the airplane’s estimated center of gravity was about 8.24 inches beyond the approved aft limit at its maximum gross weight. It is likely that the pilot’s decision to takeoff downwind and operate the airplane over the maximum gross weight with an aft center of gravity led to the aerodynamic stall during takeoff and loss of control. Downwind takeoffs result in higher groundspeeds and increase takeoff distance. While excessive aircraft weight increases the takeoff distance and stability, and an aft center of gravity decreases controllability. Several instances of the operator’s noncompliance with its operational procedures and risk mitigations were discovered during the investigation, including two overweight flights, inaccurate and missing information on aircraft flight logs, and the accident pilot’s failure to complete a flight risk assessment for the accident flight. The operator had a safety management system (SMS) in place at the time of the accident that required active monitoring of its systems and processes to ensure compliance with internal and external requirements. However, the discrepancies noted with several flights, including the accident flight, indicate that the operator’s SMS program was inadequate to actively monitor, identify, and mitigate hazards and deficiencies.

The crew departed Adak Airport on a maritime patrol flight over the north Pacific Ocean under callsign 'Alfa Fox 586'. En route, the engine n°1 oversped and the crew was unable to feather its propeller. A lack of oil caused the engine to catch fire and the crew decided to ditch the airplane about 370 km south of Attu Island. Five occupants were killed while 10 others were rescued by the crew of a Soviet trawler.

Lost without trace while completing a ferry flight from Midway Island to Adak, Aleutians Islands. The pilot did not send any distress call. SAR operations did not find any trace from the aircraft nor the pilot.

The four engine airplane was on its way from Whidbey Island NAS to Adak with an intermediate stop at Elmendorf AFB. The goal of the flight was to repatriate Navy personnel back to Whidbey Island for the Christmas period. Following an uneventful flight from Anchorage, while cruising at an altitude of 4,700 feet in limited visibility, the airplane struck the slope of a volcano located on the Great Sitkin Island, about 25 miles northeast of Adak Airfield. The aircraft was destroyed upon impact and all 10 occupants were killed.

During the takeoff roll at Adak Airport, the pilot-in-command pull the control column and started to rotate when the copilot reported a technical problem (smoke hatch blew open). The crew decided to abort the takeoff procedure and started an emergency braking manoeuvre. Few seconds later, the airplane veered off runway to the left and struck an obstacle, causing the right wing to be torn off. The airplane came to rest in flames down an embankment. All eight crew members escaped with minor injuries while the aircraft was destroyed.

A Lockheed Constellation, model L-1049H, N 6911C, owned by The Flying Tiger Line Inc., and being operated under contract with the Military Air Transport Service, crashed during the hours of darkness at Adak, Alaska, March 15, 1962, at 1214 G.m.t. Impact and subsequent fire destroyed the aircraft. There were seven occupants, all crew members. Six received minor injuries and one, the duty flight engineer, was trapped in the cockpit and died in the fire. This was a scheduled cargo flight, designated by the carrier as Flight No. FTL 7816/14. It originated at Travis Air Force Base, California, for Kadena Air Force Base, Okinawa, with stops planned at Cold Bay, Alaska, Adak, Alaska, and Misawa, Japan. Shortly after departure from Travis Air Force Base, buffeting developed and the aircraft was landed back at Travis. Inspection disclosed an open hydraulic reservoir access door. This was closed and secured and the flight proceeded uneventfully to Cold Bay, Alaska. The flight from Cold Bay to the vicinity of Adak was also uneventful, with the copilot flying the aircraft from the left seat and the captain acting as copilot in the right seat. Instrument weather prevailed at Adak and a ground controlled approach (GCA) was started. The flight was advised several times that it was below the glide slope and then was advised to execute a missed approach. The aircraft’s captain replied that the field was in sight. The approach continued, visually. At a point 328 feet short of the runway threshold and four feet below its level the landing gear struck rocks. The main landing gear was torn off and the aircraft slid about 2,000 feet on the runway coining to rest just off its edge. A severe fire developed.

Flight 3 was a scheduled flight between Anchorage and Shemya, with intermediate stops at Cold Bay and Adak, Alaska. A routine takeoff was made at Cold Bay, and all en route radio reporting points were made to the company within two or three minutes of their estimated times. At 1650LT, the flight reported that it was 100 miles northeast of Adak, at 4,500 feet, on top and in the clear. Flight 3 then estimated it would be over the Adak low frequency range at 1725LT. The flight was cleared to the Adak low frequency range, to maintain VFR on top, and to call Adak approach control when 30 miles out for landing instructions. At 1715LT, the flight advised the company it was canceling its IFR flight plan and was proceeding VFR. Two minutes later Flight 3 attempted to communicate with Adak approach control. Upon hearing this message, approach control called the flight but was unsuccessful. It was later determined that the aircraft had crashed into the northeast side of the Great Sitkin volcano (1,740 meters high) located on the Great Sitkin Island, about 25 miles northeast of Adak Airport. The aircraft was destroyed and all 16 occupants have been killed.

The crew was completing a maritime patrol flight over the North Pacific Ocean when the radio operator informed ATC he would divert to Adak for an emergency landing due to a fire on board. While approaching Adak Airport, the seaplane hit the water surface and crashed into the ocean few miles off shore, killing all 12 crew members.

On final approach to Adak Airport, the aircraft was too low and hit a sand dune short of runway threshold. It went out of control and crashed in flames. A crew member was killed while six other were injured.

Few minutes after its takeoff from Adak Airport, en route for a maritime patrol flight, the airplane hit the slope of a mountain located on the Little Tanaga Island. The wreckage was found about 20 miles southeast of Adak Airport and all 10 crew members were killed.
