Narrative:

Departed on 30 min local flight. Upon entering pattern (downwind) landing gear would not extend. Gear was frozen at mid travel. Gear circuit breakers opened when gear was cycled. Attempts to free gear with emergency gear handle were to no avail. Departed pattern and continued to attempt to free the gear. I then released the emergency retraction system and still the gear would not move beyond mid travel by using emergency gear handle. Then proceeded to ZZZ, executed a low pass confirming gear was indeed half down. I then elected to land on runway 24. Engine was secured on final. Aircraft skidded on runway 24 and came to rest with damage to propeller and under fuselage. No injuries or fire.
