Saipan Island

The pilot of a Cessna 208B aircraft, registered VH-FAY (FAY), was contracted to ferry the aircraft from Jandakot Airport, Western Australia (WA), to Greenwood, Mississippi in the United States (US). The pilot planned to fly via the ‘North Pacific Route’. At 0146 Coordinated Universal Time (UTC) on 15 September 2018, the aircraft took off from Jandakot Airport, WA, and landed in Alice Springs, Northern Territory at 0743. After landing, the pilot advised the aircraft operator that the aircraft had a standby alternator fault indication. In response, two company licenced aircraft maintenance engineers went to Alice Springs and changed the alternator control unit, which fixed the problem. Late the next morning, the aircraft departed Alice Springs for Weipa, Queensland, where the pilot refuelled the aircraft and stayed overnight. On the morning of 17 September, the pilot conducted a 1-hour flight to Horn Island, Queensland. About an hour later, the aircraft departed Horn Island with the planned destination of Guam, Micronesia. While en route, the pilot sent a message to the aircraft operator advising that he would not land in Guam, but would continue another 218 km (118 NM) to Saipan, Northern Mariana Islands. At 1003, the aircraft landed at Saipan International Airport. The next morning, the pilot refuelled the aircraft and detected damage to the propeller anti-ice boot. The aircraft was delayed for more than a week while a company engineer travelled to Saipan and replaced the anti-ice boot. At 2300 UTC on 26 September, the aircraft departed Saipan, bound for New Chitose Airport, Hokkaido, Japan. Once airborne, the pilot sent a message from his Garmin device, indicating that the weather was clear and that he had an expected flight time of 9.5 hours. About an hour after departure, the aircraft levelled out at flight level (FL) 220. Once in the cruise, the pilot sent a message that he was at 22,000 feet, had a tailwind and the weather was clear. This was followed by a message at 0010 that he was at FL 220, with a true airspeed of 167 kt and fuel flow of 288 lb/hr (163 L/hr). At 0121, while overhead reporting point TEGOD, the pilot contacted Tokyo Radio flight information service on HF radio. The pilot was next due to report when the aircraft reached reporting point SAGOP, which the pilot estimated would occur at 0244. GPS recorded track showed that the aircraft passed SAGOP at 0241, but the pilot did not contact Tokyo Radio as expected. At 0249, Tokyo Radio made several attempts to communicate with the pilot on two different HF frequencies, but did not receive a response. Tokyo Radio made further attempts to contact the pilot between 0249 and 0251, and at 0341, 0351 and 0405. About 4.5 hours after the pilot’s last communication, two Japan Air Self-Defense Force (JASDF) aircraft intercepted FAY. The pilot did not respond to the intercept in accordance with international intercept protocols, either by rocking the aircraft wings or turning, and the aircraft continued to track at FL 220 on its planned flight route. The JASDF pilots were unable to see into the cockpit to determine whether the pilot was in his seat or whether there was any indication that he was incapacitated. The JASDF pilots flew around FAY for about 30 minutes, until the aircraft descended into cloud. At 0626 UTC, the aircraft’s GPS tracker stopped reporting, with the last recorded position at FL 220, about 100 km off the Japanese coast and 589 km (318 NM) short of the destination airport. Radar data showed that the aircraft descended rapidly from this point and collided with water approximately 2 minutes later. The Japanese authorities launched a search and rescue mission and, within 2 hours, searchers found the aircraft’s rear passenger door. The search continued until the next day, when a typhoon passed through the area and the search was suspended for two days. After resuming, the search continued until 27 October with no further parts of the aircraft found. The pilot was not located.

On January 9, 1998, at 1935 hours Philippines local time, a Piper PA-31, N4111M, reportedly experienced a loss of engine power and crashed at the Ninoy Aquino International Airport, Manila, Philippines. The aircraft was substantially damage the airline transport rated pilot and copilot were not injured. Visual meteorological conditions existed for the night ferry flight to Saipan in the Marianas, and an instrument flight rules (IFR) flight plan had been filed. The pilot stated that after completing a preflight they had been cleared to taxi to the active runway. The pilot requested a full length takeoff from runway 06. Approximately 75 feet after lifting off from the ground, the pilot requested that the copilot retract the landing gear. The pilot reported that shortly after the landing gear was raised the aircraft yawed sharply to the right. He lowered the nose to regain some of the airspeed that was lost due to the right yaw. He stated that they were losing airspeed and altitude quickly, and asked the copilot to extend the landing gear. The pilot reported that on landing he had the power on until they contacted the runway. The aircraft slid to the left and came to rest after striking a concrete ditch. A test flight of the accident aircraft had been conducted 2 days and on the day before the accident. The purpose of the test flights were to check the propellers that had been overhauled, and to obtain a ferry permit from the Federal Aviation Administration's Designated Airworthiness Representative (DAR). The DAR found the aircraft to be within required specifications. He made the appropriate entry into the aircraft's logbook and issued the ferry authorization.

Enroute, the left engine caught fire. The crew was unable to extinguish the fire and shortly later, the engine detached. All 17 occupants decided to abandon the aircraft and to bail out when the aircraft went out of control and crashed into the ocean some 96 km northwest of Saipan Island. Five passengers were rescued while 12 other occupants were killed.
