Unalaska

The airline transport pilot was on an approach to land on Runway 30 at the conclusion of a visual flight rules (VFR)scheduled commuter flight. Through a series of radio microphone clicks, he activated threshold warning lights for vehicle traffic on a roadway that passes in front of the threshold of Runway 30. Gates that were supposed to work in concert with the lights and block the runway from vehicle traffic were not operative. On final approach, the pilot, who was aware that the gates were not working, noticed a large truck and trailer stopped adjacent to the landing threshold. As he neared the runway, he realized that the truck was moving in front of the threshold area. The pilot attempted to go around, but the airplane's belly struck the top of the trailer and the airplane descended out of control to the runway, sustaining structural damage. The truck driver reported that, as he approached the runway threshold, he saw the flashing red warning lights, but that the gates were not closed. He waited for about 45 seconds and looked for any landing traffic and, seeing none, drove onto the road in front of the threshold. As he did so, he felt the airplane impact the trailer, and saw it hit the runway. The accident truck's trailer is about 45 feet long and 13 feet tall. The Federal Aviation Administration (FAA) Facility Directory/Alaska Supplement recommends that pilots maintain a 25-foot minimum threshold crossing height. The NTSB's investigation revealed that the gate system had been out of service for more than a year due to budgetary constraints, and that there was no Notice to Airman (NOTAM) issued concerning the inoperative gate system. The FAA certificated airport is owned and operated by the State of Alaska. According to the Airport Certification Manual, the airport manager is responsible to inspect, maintain, and repair airport facilities to ensure safe operations. Additionally, the airport manager is responsible for publishing NOTAM's concerning hazardous conditions. A 10-year review of annual FAA certification and compliance inspection forms revealed no discrepancy listed for the inoperative gates until 16 days after the accident.

A Douglas DC-3 airplane departed an island runway during dark night, VFR conditions without filing a flight plan. The airplane collided with a volcanic mountain at 1,500 feet msl on the runway heading, 4.5 miles from the airport. Earlier in the day, the airplane arrived from Anchorage, Alaska, without a flight plan, having flown along the Alaska Peninsula when VFR flight was not recommended. The crew of the airplane initially planned to remain overnight on the peninsula, but the captain received a request to transport cargo to Anchorage. The airplane was loaded with cargo and fuel, and departed. The crew did not file a flight plan. The end of the departure runway is positioned at the edge of an ocean bay. Beyond the end of the runway, open water and rising volcanic island terrain are present. In the area of intended flight, no illumination of the terrain, or any ground based lighting was present. An obstacle departure procedure for the departure runway recommends a right turn at 2 DME from the runway heading, and then a climb to 7,000 feet. Forty-five minutes after departure, a fire was spotted on the side of a volcano cone, and an ELT signal was detected in the area. No company flight following procedures were found for the accident flight, and the airplane was not reported overdue until the following day. The day after the accident, the airplane wreckage was located on steep, snow-covered terrain. Due to high winds and blowing snow, a rescue team could not get to the accident site until three days after the crash. The captain was the president, the director of operations, and the sole corporate entity of the company. No current maintenance records, flight logs, or pilot logs were located for the company. In the past, the captain's pilot certificate was suspended for 45 days following an accident in a DC-3 airplane when he ran out of gas. Also, the captain's medical certificate had previously been considered for denial after serving 49 months in federal prison for cocaine distribution, but after review, the FAA issued the captain a first class medical. FAA medical records for the captain do not contain any record of monitoring for substance abuse. The first officer's medical had also been considered for denial after an episode of a loss of consciousness. After a lengthy review and an appeal to the NTSB, the FAA issued the first officer a second-class medical. The first officer was part of the flight crew when the captain ran out of gas, and she had two previous aviation accidents. A toxicological examination of the captain, conducted by the FAA, found cocaine and metabolites of cocaine. A toxicological examination of the first officer found two different prescription antidepressant drugs. The FAA prohibits narcotic and mood-altering drug use by pilots.

The aircraft was on its way from Kodiak to Unalaska, carrying a crew of five and fifteen members of a Navy football team. While cruising some 250 km from the destination, the crew informed ground he encountered strong head winds. Shortly later, the seaplane crashed in unknown circumstances into the sea. All 20 occupants were killed.

Ensign Johnson was crewman in a Navy PBY-5A that had been running baselines for calibrating new LORAN stations in Alaska. While attempting to enter Unalaska Bay for a landing at Dutch Harbor, during weather conditions of low visibility and rain, the pilot made a landfall in the bay which he did not recognize. Feeling that a turn would probably result in a collision with a mountainside, the pilot elected to land in this bay. After readying the aircraft for a water landing he proceeded to make a normal landing, but was unaware of the height of the ground swells (approximately 5-feet). Immediately after contacting the water, the aircraft nosed into a ground swell and broke apart at the pilot's compartment. The wing broke off and the plane filled with water and sank. ENS Charles E. Johnson was killed, along with two Navy crewmen. The ten others aboard, including the pilot, were injured but survived.
