Narrative:

On jan/xa/99 I was landing during daylight hours, in clear WX, no wind conditions at my home field (O56, gnoss field) near novato, ca. I was plting an experimental aircraft, a CJ6 chinese military trainer. I had not flown this aircraft for approximately 1 month. During the approach, the gear and flap deployed normally. Gear deployment was confirmed visually and electronically (lights). Speed on final approach was slightly fast (90 KTS -- normal is 80-85 KTS) and I decided to 'land long.' touchdown was at midfield on runway 31 and was normal in all ways. I braked 2 times to slow the aircraft, without problems. As I applied the brakes a third time, I felt the airplane 'settle' and realized the gear had collapsed. On rollout, I apparently hit the gear deployment lever with my left knee, forcing the lever into the neutral position and causing the gear to collapse. The plane was traveling approximately 10-15 mph at this point. The aircraft came to rest near the end of runway 31. I was the pilot and sole occupant and was not injured. There was minimal damage to the airframe, but there was a propeller strike. The airport was briefly closed as the aircraft was raised and towed off the runway. I believed that the gear handle in its detent position 'locked' the gear down. This was part of my primary and recurrent training in this aircraft. I subsequently learned that the manual lock -- which I thought was used only to hold the gear in the neutral position, should also be engaged with the gear handle in the 'down' position to prevent the gear handle from inadvertently entering the neutral position as was the case here.

Title: A PVT PLT EXPERIENCES A GEAR COLLAPSE AND A PROP STRIKE ON HIS CHINESE MADE CJ6 WHEN HIS LEG ACCIDENTALLY HIT THE GEAR LEVER TO THE NEUTRAL POS DURING A LONG LNDG.

Narrative: ON JAN/XA/99 I WAS LNDG DURING DAYLIGHT HRS, IN CLR WX, NO WIND CONDITIONS AT MY HOME FIELD (O56, GNOSS FIELD) NEAR NOVATO, CA. I WAS PLTING AN EXPERIMENTAL ACFT, A CJ6 CHINESE MIL TRAINER. I HAD NOT FLOWN THIS ACFT FOR APPROX 1 MONTH. DURING THE APCH, THE GEAR AND FLAP DEPLOYED NORMALLY. GEAR DEPLOYMENT WAS CONFIRMED VISUALLY AND ELECTRONICALLY (LIGHTS). SPD ON FINAL APCH WAS SLIGHTLY FAST (90 KTS -- NORMAL IS 80-85 KTS) AND I DECIDED TO 'LAND LONG.' TOUCHDOWN WAS AT MIDFIELD ON RWY 31 AND WAS NORMAL IN ALL WAYS. I BRAKED 2 TIMES TO SLOW THE ACFT, WITHOUT PROBS. AS I APPLIED THE BRAKES A THIRD TIME, I FELT THE AIRPLANE 'SETTLE' AND REALIZED THE GEAR HAD COLLAPSED. ON ROLLOUT, I APPARENTLY HIT THE GEAR DEPLOYMENT LEVER WITH MY L KNEE, FORCING THE LEVER INTO THE NEUTRAL POS AND CAUSING THE GEAR TO COLLAPSE. THE PLANE WAS TRAVELING APPROX 10-15 MPH AT THIS POINT. THE ACFT CAME TO REST NEAR THE END OF RWY 31. I WAS THE PLT AND SOLE OCCUPANT AND WAS NOT INJURED. THERE WAS MINIMAL DAMAGE TO THE AIRFRAME, BUT THERE WAS A PROP STRIKE. THE ARPT WAS BRIEFLY CLOSED AS THE ACFT WAS RAISED AND TOWED OFF THE RWY. I BELIEVED THAT THE GEAR HANDLE IN ITS DETENT POS 'LOCKED' THE GEAR DOWN. THIS WAS PART OF MY PRIMARY AND RECURRENT TRAINING IN THIS ACFT. I SUBSEQUENTLY LEARNED THAT THE MANUAL LOCK -- WHICH I THOUGHT WAS USED ONLY TO HOLD THE GEAR IN THE NEUTRAL POS, SHOULD ALSO BE ENGAGED WITH THE GEAR HANDLE IN THE 'DOWN' POS TO PREVENT THE GEAR HANDLE FROM INADVERTENTLY ENTERING THE NEUTRAL POS AS WAS THE CASE HERE.
