The pilot of the skydiving aircraft (Cessna U206A Super Skywagon, C206A, OHCSU) took off on 8 August 2020 at 17:39 LT (14.39 UTC) at nearly the maximum take-off weight from runway 19 of Immola airfield. In addition to the pilot, there were five skydivers in the aircraft, which had been refuelled before the flight with 120 litres of AVGAS 100 LL fuel.
The weather was hot and there was almost no wind at Immola. At the nearest airport covered by the aviation meteorological service of the Finnish Meteorological Institute (Lappeenranta, at a distance of approximately 50 km), the valid METAR weather report was EFLP 081420Z AUTO 27006KT 230V310 9999 VCSH //////CB 26/16 Q1021=.
The aircraft took off, but in the pilot’s opinion, it did not seem to accelerate well enough. The pilot decided to carry out an emergency landing on the grass on the right side of the runway, taking account of the approaching end of the runway and the obstacles behind it. The aircraft landed heavily on its main landing gear and bounced into the air, after which it hit the ground again, rolling over its nose landing gear, nose and left wingtip onto its roof with the nose facing in the direction where the aircraft took off. The skydivers in the aircraft managed to exit the aircraft and helped the pilot out, too. One person inside the aircraft was severely injured and five suffered minor injuries.
The Finnish Transport and Communications Agency (Traficom) deemed it necessary to investigate the causes and consequences of the aviation accident with regard to the organisation, legislation and flight training. The primary goal of the investigation was to promote and develop aviation safety.
