Flight and Go-Around
The pilot completed the departure, en route, and descent portions of the visual flight rules (VFR) flight without incident. After entering the traffic pattern, the pilot turned final and announced intentions. The pilot then observed an airplane holding short for the same runway and made another announcement. When the pilot was approximately 100 to 150 feet above ground level, the airplane holding short pulled onto the runway. The pilot executed a go-around, retracted the flaps and landing gear, and then performed a left 360-degree turn, placing the airplane back on final.
Landing and Gear Retraction
The pilot recalled the airplane touching down and believes the landing gear retracted during the ground roll. The airplane slid approximately 100 feet before coming to a stop. After the accident, the pilot realized the landing gear switch was in the up position.
Post-Accident Examination
Examination of the airplane revealed no damage to the landing gear doors or side scuffing on either tire. Additionally, no preimpact failures were identified with the squat switch, the safe gear indication system, or the landing gear horn.
