What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On October 25, 2014 at approximately 1300 the pilot was conducting a power-off approach to a stall with a student. At the sound of the stall warning the nose was lowered, power was added and flaps reduced to 15 deg. When a positive rate of climb was established the landing gear was moved to the "up" position. There was an audible 'thump' sound, the nose and left gear indicators showed green, the right gear light was out and the gear in transit light remained on. Several cycles were attempted with the same result. Pilot went through the emergency gear extension by reference to the POH with the same results. Right gear was up and the nose and left were showing down. Cranked the gear up and declared emergency, a gear and flap up approach was made to runway 9. The aircraft touched down on centerline at approximately the 1550 foot marker. The aircraft slid to a stop swerving to the right edge of the runway. Pilot and student exited the aircraft with no injuries. Both propellers were damaged and minor damage to nose gear doors and belly skin.
