Transair Flight 810

Transair Flight 810 was a flight operated by a Boeing 737-200 converted freighter aircraft, owned and operated by Rhoades Aviation under the Transair trade name, on a short cargo flight from Honolulu International Airport to Kahului Airport on the neighboring Hawaiian island of Maui on July 2, 2021. Immediately after an early morning takeoff, one of its two Pratt & Whitney JT8D turbofan engines faltered, and the first officer reduced power to both engines. The two pilots—the only occupants of the aircraft—became preoccupied with talking to air traffic control and performing other flying tasks, and did not follow proper procedures to positively identify the problem. The captain misidentified the failing engine, increased power to that engine, and did not increase power to the other, properly functioning engine. Convinced that neither engine was working properly and unable to maintain altitude with one engine faltering and the other idling, the pilots ditched into Honolulu's Māmala Bay off the coast of Oahu about 11 minutes into the flight.

Both pilots were rescued about an hour after the accident in a response involving aircraft and boats from multiple agencies. They were hospitalized and later released. The wreckage was located the following week at a depth of about 420 feet (130 m), 2 miles (3 km) off Ewa Beach and was subsequently recovered.

The Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB) immediately began investigating the accident. Transair voluntarily withdrew its four remaining 737s from service for an internal review. Transair resumed flying their one operational 737-200 a week later, but subsequently had to cease 737 operations due to deficiencies identified by the FAA prior to the ditching. The NTSB report cited the pilots' ineffective crew resource management, high workload, and stress.

This accident is similar to the 1989 Kegworth air disaster (British Midland Airways Flight 092), where a 737-400 crashed after the crew misidentified the failing engine and erroneously shutdown the operating engine, causing the aircraft to stall during an emergency landing.
