What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot in command (PIC) was giving instruction to the non-picprivacy data omitted in order for him to apply for his certified flight instructor (CFI) multi engine rating. The non-picprivacy data omitted completed a short field landing as a touch and go. According to the cfi/pic the soft field technique was not adequate so the cfi/pic then demonstrated the next short field landing but when attempting to raise the flaps on rollout, instead, raised the landing gear handle momentarily. The right main and nose landing gears partially retracted (collapsed) causing the nose landing gear door, right lower engine cowling and both propellers to contact the runway surface. The aircraft came to rest on the right side of the runway.
