How a single engine error led to a Boeing 737 ditching in Hawaii
In short: In the early hours of July 2, 2021, a cargo flight over Oahu became a desperate struggle for survival. What began as a mechanical failure in one engine spiraled into a fatal misidentification, leaving two experienced pilots fighting to stay airborne as their aircraft descended into Māmala Bay.
The disaster of Transair Flight 810 was not caused by a total loss of power, but by a breakdown in crew resource management. During takeoff from Honolulu, a Pratt & Whitney JT8D turbofan engine suffered stress fractures due to oxidation and corrosion in the high-pressure turbine blades. Although the crew accurately noted the right engine's thrust reduction, intense pressure and diversions dominated the cabin's atmosphere. The failure occurred shortly after the aircraft departed Daniel K. Inouye International Airport at 1:33 a.m. HST. This specific engine type was originally designed for the Boeing 727.
As the crew communicated the emergency to air traffic control, a critical error occurred: the first officer misidentified the left engine as the failing unit. The captain, distracted by radio communications and operating under the assumption that his colleague was infallible, failed to verify this finding. Instead of increasing power to the functioning right engine, the captain increased power to the failing one, while the left engine was left at near-idle power. The crew had requested delay vectors to run a checklist rather than immediately returning to the airport. This decision left them unable to sustain flight as they continued on a southwest heading.
This error mirrors the 1989 Kegworth air disaster, where a similar misidentification led to the shutdown of a working engine. Unable to maintain altitude with one engine failing and the other idling, the pilots ditched the 45-year-old Boeing 737-200 into the ocean about 11 minutes into the flight. Though both pilots were rescued from the wreckage and floating cargo, the accident prompted intense scrutiny of Rhoades Aviation, eventually leading to the revocation of their air operator's certificate in 2022. The wreckage was eventually located 2 miles off Ewa Beach at a depth of approximately 420 feet. Both pilots survived the impact, though the captain required hospitalization for serious injuries.
