Narrative:

Flying back to pasco after a biannual flight review I requested that the pilot do some lndgs. I suggested pasco as runway 21R is 7700' long. Pilot lowered gear about 3 mi out. I did a mental checklist and confirmed gear down. Landing proceeded without event. (The intercom in the plane does not permit passenger to hear what the pilot's communication is with the tower.) on rollout, the left gear went up and the plane slid to a stop, left wing on the ground. Damaging the propeller and all gear doors. Subsequent investigation showed that the gear switch had been moved to the up position. Pilot claimed that I (the CFI) had called for a touch and go and that he got rattled and pulled the wrong switch. I was intending full stop in accordance with far 61.57(D). I think this is a good case of miscom in the cockpit and should be brought to your attention.

Narrative: FLYING BACK TO PASCO AFTER A BIANNUAL FLT REVIEW I REQUESTED THAT THE PLT DO SOME LNDGS. I SUGGESTED PASCO AS RWY 21R IS 7700' LONG. PLT LOWERED GEAR ABOUT 3 MI OUT. I DID A MENTAL CHECKLIST AND CONFIRMED GEAR DOWN. LNDG PROCEEDED WITHOUT EVENT. (THE INTERCOM IN THE PLANE DOES NOT PERMIT PAX TO HEAR WHAT THE PLT'S COM IS WITH THE TWR.) ON ROLLOUT, THE LEFT GEAR WENT UP AND THE PLANE SLID TO A STOP, LEFT WING ON THE GND. DAMAGING THE PROPELLER AND ALL GEAR DOORS. SUBSEQUENT INVESTIGATION SHOWED THAT THE GEAR SWITCH HAD BEEN MOVED TO THE UP POSITION. PLT CLAIMED THAT I (THE CFI) HAD CALLED FOR A TOUCH AND GO AND THAT HE GOT RATTLED AND PULLED THE WRONG SWITCH. I WAS INTENDING FULL STOP IN ACCORDANCE WITH FAR 61.57(D). I THINK THIS IS A GOOD CASE OF MISCOM IN THE COCKPIT AND SHOULD BE BROUGHT TO YOUR ATTN.
