Charter/Taxi (Non Scheduled Revenue Flight)

While enroute in instrument meteorological (IMC) conditions, the pilot of the twin-engine, piston-powered airplane declared an emergency following a loss of power to the right engine. The pilot secured the engine and was provided vectors by air traffic control for an instrument approach procedure at the nearest airport, which he successfully completed. The pilot reported that he flew the approach and landing with the wing flaps retracted and visually acquired the runway about 500 ft above the ground. The airplane touched down on the first third of the runway at 120 knots. The pilot knew he would not be able to stop the airplane on the 3,500-ft long runway but committed to the landing rather than risking a single-engine go-around in IMC. After landing, the airplane continued beyond the departure end of the runway and impacted a berm, collapsing the landing gear and resulting in substantial damage to the airplane. Examination of the engine revealed catastrophic damage consistent with detonation and oil starvation. The damage to the No. 5 cylinder was consistent with a subsequent over pressurization of the crankcase, which likely expelled the crankshaft nose seal and the oil supply. Detonation of the cylinder(s) can create excessive crankcase pressures capable of expelling the crankshaft nose seal. The crankshaft nose seal displacement likely created a rapid loss of oil and the resulting oil starvation of the engine. The fractured connecting rod and high-temperature signatures were consistent with oil starvation. No source or anomaly that would result in engine detonation was identified. According to the Pilot’s Operating Handbook (POH) for the accident airplane, during a single engine inoperative approach, the pilot should maintain an airspeed of 116 kts indicated (KIAS) or above until landing is assured. Once landing is assured, the pilot should extend the gear and flaps, slowly retard the power on the operative engine, and land normally. The airplane’s best single-engine rate of climb speed (blue line) was 106 KIAS, and its minimum controllable airspeed with one engine inoperative (Vmca) was 76 KIAS. The maximum speed for full flap extension (40°) was 132 KIAS. The POH also stated that a single-engine go-around should be avoided if at all possible. The pilot’s decision to commit to the landing was reasonable given the circumstances and the guidance provided by the POH; however, it is likely that his decision to conduct the landing without flaps and the airplane’s excessive airspeed at touchdown resulted in the runway overrun.

The pilot reported that while on approach for landing, the airplane started to lose altitude quickly. After the co-pilot noticed the high decent rate and the slow airspeed, he advised the pilot to add power. However, the airplane continued to descend and impacted terrain in a right wing and nose low attitude, about 30 yards short of the runway approach threshold, which resulted in substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

While taking off from Provo Airport runway 13/31, the airplane went out of control and crashed. Both passengers escaped with minor injuries while both pilots were seriously injured. One of them died from injuries sustained. The airplane was destroyed. It was snowing at the time of the accident.

After landing at Mweya Airstrip located in the Queen Elizabeth National Park, the single engine airplane was unable to stop within the remaining distance. It overran and collided with a house. All five occupants escaped uninjured and the aircraft was damaged beyond repair. It just completed a charter flight with three European citizens and two pilots on board.

After landing on runway 08 at Lewistown Airport, the twin engine airplane started to skid then veered off runway to the left. While contact a snow covered terrain, it slid for few dozen metres and came to rest with its left wing severely damaged. All three occupants evacuated safely.

The two pilots were conducting a business flight with six passengers when the accident occurred. During the night arrival the captain flew a visual approach with excessive airspeed
and the airplane crossed the runway threshold more than 50 knots above approach speed (Vref). The before-landing checklist was not completed, and the flaps were at an incorrect 20° position instead of 40°. The airplane touched down near the midfield point of the 6,022 ft non grooved runway, which was wet due to earlier precipitation. The captain initially applied intermittent braking, then applied continuous braking starting about 2,069 ft from the end of the runway. The captain did not deploy the thrust reversers. The airplane exited the runway above 100 knots ground speed, then continued into a ditch and airport perimeter fence, which resulted in substantial damage to the forward fuselage. Examination of the airplane revealed no mechanical anomalies that would have precluded normal operation. The operator’s flight manual directed that all approaches were to be flown using the stabilized approach concept. For a visual approach, this included establishing and maintaining the proper approach speed and correct landing configuration at least 500 ft above the airport elevation. Neither pilot recognized the requirement to execute a go-around due to the excessive approach speed or the long landing on a wet runway, which resulted in the runway excursion.

The twin engine airplane was chartered by the Grupo San Germán Express to carry a team of six people from Medellín to Pizarro, Chocó. Shortly after takeoff from runway 02 at Medellín-Enrique Olaya Herrera Airport, while in initial climb, the crew encountered engine problems. The airplane went out of control and crashed onto a house located in the district of Belén Rosales, less than 500 metres from the runway end, bursting into flames. The house and the aircraft were destroyed and all 8 occupants were killed.

On 12 October 2022, the True North Airways Inc. de Havilland DHC-3 Otter aircraft on floats (registration C-FDDX, serial number 165) was conducting a visual flight rules flight, with 1 pilot on board, from Mistissini Water Aerodrome (CSE6), Quebec, to Pluto Lake, Quebec, where it would deliver cargo and pick up passengers. At approximately 0929 Eastern Daylight Time, while manoeuvring for landing on Pluto Lake, the aircraft collided with the surface of the water. The pilot sustained serious injuries. The passengers, who had been waiting near the lake for the aircraft’s arrival, transported the pilot to a nearby cabin from where he was later taken to hospital by a search and rescue helicopter. The emergency locator transmitter activated. There was significant damage to the aircraft.

On the afternoon of 3 October 2022, a Pilatus Britten-Norman Islander BN2A-21, registered VHWQA and operated by Torres Strait Air, was conducting a non-scheduled passenger air transport flight from Saibai Island Airport, Queensland (QLD) to Horn Island Airport, QLD. There was 1 pilot and 6 passengers (students) on board. About 19 km NE of Moa Island both engines began to surge. The pilot diverted towards Kubin Airport on Moa Island. As the aircraft passed to the south of the township of Saint Pauls, the pilot determined there was insufficient altitude remaining to reach the airport. As a result, the pilot conducted a forced landing on a road 7 km ENE of Kubin Airport. There were no reported injuries to the pilot or the passengers. The aircraft was substantially damaged.

After takeoff from Porto Trombetas Airport, the pilot encountered engine problems and attempted an emergency landing. The airplane crashed in a wooded area and was destroyed. The pilot was killed and all four passengers were injured. They were en route to Ayaramã to provide dental assistance to locals. On board were one dentist, one assistant, one nurse and one employee of the Brazilian Institute for Geography and Statistics.
