Narrative:
The Beechcraft 200 King Air, LN-NOA, landed gear-up on runway 18 at Stavanger-Sola Airport in Norway. The aircraft skidded 278 m along the runway before it came to rest. The aircraft carried medical isotopes for a hospital.
The crew was uninjured, while the aircraft suffered damage to the nose wheel mechanism, both propellers, belly and the trailing edge of the flaps.

The crew explained that the landing gear collapsed when the aircraft landed. They experienced that the aircraft banked slightly to the left just after landing and the commander, who was PM (Pilot Monitoring), reacted by placing his hand on the landing gear handle to check if it was completely down. Furthermore, he explained that he retracted the handle in a reflex action, but quickly placed it down again. According to the crew, this led the landing gear to retract resulting in the aircraft taking the ground with its belly.
The NSIA has attempted to find a link between the crew's explanation and the investigation findings, but without finding a complete match. A thorough inspection of the landing gear was carried out after the accident without any significant technical issues located in the system.

Probable Cause:

The NSIA believes that the landing gear was either in transit when they landed or that it was completely retracted, which resulted in a belly landing.
