Dillingham (O'ahu Island)

On June 21, 2019, about 1822 Hawaii-Aleutian standard time, a Beech King Air 65-A90 airplane, N256TA, impacted terrain after takeoff from Dillingham Airfield (HDH), Mokuleia, Hawaii. The pilot and 10 passengers were fatally injured, and the airplane was destroyed. The airplane was owned by N80896 LLC and was operated by Oahu Parachute Center (OPC) LLC under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91 as a local parachute jump (skydiving) flight. Visual meteorological conditions prevailed at the time of the accident. OPC had scheduled five parachute jump flights on the day of the accident and referred to the third through fifth flights of the day as “sunset” flights because they occurred during the late afternoon and early evening. The accident occurred during the fourth flight. The accident pilot was the pilot-in-command (PIC) for each of the OPC flights that departed on the day of the accident. The pilot and 8 of the 10 passengers initially boarded the airplane. These eight passengers comprised three OPC tandem parachute instructors, three passenger parachutists, and two OPC parachutists performing camera operator functions. The pilot began to taxi the airplane from OPC’s location on the airport. According to a witness (an OPC tandem instructor who was not aboard the accident flight), the two other passengers—solo parachutists who had been on the previous skydiving flight and were late additions to the accident flight—“ran out to the airplane and were loaded up at the last minute.” The pilot taxied the airplane to runway 8 about 1820, and the airplane departed about 1822. According to multiple witnesses, after the airplane lifted off, it banked to the left, rolled inverted, and descended to the ground. One witness stated that, before impact, the airplane appeared to be intact and that there were no unusual noises or smoke coming from the airplane. A security camera video showed that the airplane was inverted in a 45° nose-down attitude at the time of impact. The airplane impacted a grass and dirt area about 630 ft northeast of the departure end of the runway, and a postcrash fire ensued. The airplane was not equipped, and was not required to be equipped, with a cockpit voice recorder or a flight data recorder. The accident flight was not detected by radar at the Federal Aviation Administration’s (FAA) Hawaii Control Facility, which was the air traffic control (ATC) facility with jurisdiction of the airspace over HDH. The FAA found no audio communications between the accident airplane and ATC on the day of the accident.

Following the 12th sport parachute jump of the day, which occurred after sunset, ground witnesses observed the airplane descend into the ocean in a left wing low, nose down attitude. They did not hear the engines sputtering or popping, or see the airplane make any erratic movements during its descent. Skydivers indicated that the two previous flights had been conducted at altitudes of at least 18,000 feet, and the accident flight and subsequent jump were made at 20,000 feet. During this final jump flight, one of the skydivers stated he had a hard time breathing and felt nauseous. The skydivers also noted that the pilot was unable to maintain a steady course and did not respond well to minor course corrections. No supplemental oxygen was found onboard the airplane during the recovery or subsequent inspection phases of the investigation. No skydiver observed the pilot using supplemental oxygen. The airplane manufacturer noted that the pressurization system would have been rendered inoperable due to a non-sealed cockpit door. Hypoxia is defined as a physiological condition where a person is bereft of needed oxygen. Judgment is poor and reaction time delayed. Total incapacitation coupled with a loss of consciousness can occur with little or no warning. The airframe, engines, and propellers were examined with no preexisting impact anomalies found.
