Flipped over during landing, TL Ultralight s.r.o. TL-3000 Sirius, Ameland Airport
During landing the aeroplane flipped over and came to a halt upside down. The aeroplane was substantially damaged.
The Dutch Safety Board previously investigated a similar accident with PH-4S1 at Middenmeer airfield on 30 December 2019. The Board concluded that unstable weather conditions which led to increased pilot workload, as well as a correction to a slightly too flat final approach, resulted in a lower than normal nose position during flaring. This resulted in a bumpy landing, and subsequently the breaking of the nose wheel leg and the aircraft nosing over.
The three similar accidents in the Netherlands (in 2019, 2020 and 2021) with TL-3000 Sirius aircraft all took place during landing and are characterised by a broken-off nose landing gear, followed by the nosing over of the aircraft. The Dutch Safety Board has not further investigated the design of the nose landing gear, because the focus of the investigation was on the operational aspects. The Middenmeer Safety Committee investigated both occurrences and shared its results with the Dutch Safety Board. These results have been used in the investigation by the Dutch Safety Board.
