Incident Overview
While practicing landings and takeoffs, the pilot in command (PIC) inadvertently moved the landing gear switch into the retract cycle during the rollout phase. This action caused the landing gear to begin its retraction sequence while the aircraft was still on the runway, resulting in damage to the retraction system.
Pilot Actions
After the inadvertent retraction, the pilot elected to take off. Once airborne, the pilot was unable to cycle the landing gear in either direction, indicating a malfunction of the retraction system.
Landing and Outcome
The pilot proceeded to land with the landing gear in an intermediate position due to the inability to extend or retract it fully. Upon touchdown, the landing gear collapsed.
Damage
The retraction system was damaged during the initial retraction on the runway, and the subsequent landing gear collapse likely caused additional damage to the aircraft structure.
