In command was 30-year-old Captain Bruce Antonio Pollard.[6] He started his aviation career at Aloha IslandAir with Princeville Airways, which was eventually formed into Aloha IslandAir. He started as a ramp agent, and then became a first officer in April 1988. He upgraded to the role of captain just 15 months later in August 1989. The captain had one other incident and one violation with the Federal Aviation Administration. The incident occurred in February 1986 with a Piper PA-28 Cherokee in Juneau, Alaska. Pollard lost horizontal directional control of his aircraft while on approach, and ground looped on the runway. The cause was determined to be malfunctioning brakes. The violation occurred four years prior to the crash of Flight 1712, when Pollard was determined by the Federal Aviation Administration to have violated 14 CFR Part 135,[2] when he acted as pilot-in-command on five air taxi flights, despite the fact that he had not had proper certification, and for operating an aircraft in a careless of reckless matter. He had his commercial pilot licence suspended for six months. At the time of the accident, Pollard had logged 3,542 flight hours, 1668 of which were logged on the Twin Otter 300.[5][3]: 11
Pollard's co-pilot was 27-year-old First Officer Philip Edwin Helfrich. His first position at the airline was also as a ramp agent, which started in July 1988. He began flight lessons in August 1987. With 62 flight hours, he received his private pilot licence and single-engine land rating only three months after, on November 11, 1987. He continued with flight lessons, whilst building stature in the airline by continuing with his ramp agent position. Seventeen months after receiving his PPL, with 233 flight hours logged, he received his commercial pilot licence, with single and multi-engine land and instrument ratings. Aloha IslandAir hired him as a first officer in August 1989, and completed a 14 CFR Part 135.297 flight check the same month. At the time of the accident, he had logged 425 flight hours, including 189 logged on the Twin Otter 300.[3]: 11–12
Passengers
The 18 passengers included 5 girls volleyball team players and their head coach, 3 boys volleyball team players, and the athletic director of Molokaʻi High School. There were also 4 Hawaii locals onboard, 2 passengers from Pennsylvania and 2 passengers from Texas. No cabin crew were onboard, as they are not required for CFR Part 135 airlines.[6][7][8]
Accident
Earlier on the day of the accident, the same crew flew six uneventful inter-island flights on the same aircraft. Flight 1712 operated from Hana Airport, to Kahului Airport, and was scheduled to continue to Molokai Airport, and to terminate at Honolulu International Airport. The aircraft arrived at Kahului from Hana at 18:15 local time. The sun had set 22 minutes earlier, at 17:53 local time.[7][9] The flight departed Kahului Airport for Molokai Airport at 18:25 local time while flying under the visual flight rules. Twelve minutes later, at approximately 18:37 local time, while the aircraft maintained an altitude of about 600 feet with 150 knots, the aircraft impacted mountainous terrain killing everyone onboard. After disappearing from radar, the flight was officially declared missing at around 19:30 local time. The wreck was found the next morning within the mountains near Molokai Airport at an elevation of about 600 feet.[10][11][3]: 8
Cause
The National Transportation Safety Board determined that the probable cause of the accident was the fateful decision of Captain Pollard to continue flying under the visual flight rules despite flying into instrument meteorological conditions at night which, in-terms, obscured rising mountainous terrain which lead to an eventual impact with the mountains. The bpard also stated that the accident was influenced by Aloha IslandAir management's inadequate supervision of staff, training, and operations. Additionally, there was a lack of sufficient oversight from the Federal Aviation Administration regarding Aloha IslandAir during a time of significant operational growth and expansion.[3]: 3
