Narrative:

A visual landing was made with 1/2 flap extension in a 15+ KT right crosswind, followed by a normal rollout on patchy ice and snow covered runway. After a 180 degree turn on the runway, the aircraft was taxied back on the runway and along a short taxiway for parking on the ramp. After shutdown, it was noticed by a passerby that the r-hand propeller tips were damaged. The pilot and passenger were unaware of any abnormalities during landing or rollout and taxi thereafter. Subsequent inspection of the runway in the approximately landing area revealed several marks from the propeller. It would appear that a combination of factors contributed to the mishap: strong crosswind, very cold temperature, minimal propeller clearance, runway slope and crown, snow covered terrain and pilot technique and minimal time in aircraft model. Although not apparent at the time, a flatter than expected touchdown attitude probably resulted from an upslope in the touchdown area and lack of depth perception due to snow cover. Awareness of all factors may prevent recurrence.

Original NASA ASRS Text

Title: PLT OF AN SMA TWIN HAD PROP STRIKE DURING LNDG DUE TO XWIND AND UPSLOPE OF THE RWY GRADIENT.

Narrative: A VISUAL LNDG WAS MADE WITH 1/2 FLAP EXTENSION IN A 15+ KT R XWIND, FOLLOWED BY A NORMAL ROLLOUT ON PATCHY ICE AND SNOW COVERED RWY. AFTER A 180 DEG TURN ON THE RWY, THE ACFT WAS TAXIED BACK ON THE RWY AND ALONG A SHORT TXWY FOR PARKING ON THE RAMP. AFTER SHUTDOWN, IT WAS NOTICED BY A PASSERBY THAT THE R-HAND PROP TIPS WERE DAMAGED. THE PLT AND PAX WERE UNAWARE OF ANY ABNORMALITIES DURING LNDG OR ROLLOUT AND TAXI THEREAFTER. SUBSEQUENT INSPECTION OF THE RWY IN THE APPROX LNDG AREA REVEALED SEVERAL MARKS FROM THE PROP. IT WOULD APPEAR THAT A COMBINATION OF FACTORS CONTRIBUTED TO THE MISHAP: STRONG XWIND, VERY COLD TEMP, MINIMAL PROP CLRNC, RWY SLOPE AND CROWN, SNOW COVERED TERRAIN AND PLT TECHNIQUE AND MINIMAL TIME IN ACFT MODEL. ALTHOUGH NOT APPARENT AT THE TIME, A FLATTER THAN EXPECTED TOUCHDOWN ATTITUDE PROBABLY RESULTED FROM AN UPSLOPE IN THE TOUCHDOWN AREA AND LACK OF DEPTH PERCEPTION DUE TO SNOW COVER. AWARENESS OF ALL FACTORS MAY PREVENT RECURRENCE.
