Probable cause

The pilot of the other airplane delayed compensation for turbulence. A factor was the turbulence.

The pilots' delayed compensation for turbulence. A factor was the turbulence.

Analysis

The pilot had landed and taxied to the loading area in preparation for an aerial application run. As the pilot remained in the airplane with the engine at idle he observed the second airplane approaching the threshold for landing to the east. The pilots reported the wind from the south at 5 to 10 knots and turbulence in the vicinity of the threshold as the wind passed a hangar area near the runway. During the landing flare the airplane pilot delayed his compensation for the turbulence and the right wing of the airplane struck the rotating propeller of the standing airplane. Approximately four feet of the right wing separated from the landing airplane. The pilot applied full power and continued to a nearby airport and landed without further incidence.

During a VFR landing flare the wind was reported by the pilots as 90 degrees to the runway at approximately 10 knots. One pilot had landed and was parked in the loading area to the right of the threshold. This pilot reported turbulence in the vicinity of the landing threshold as the wind passed the hangar area near the runway. During the landing flare the second airplane pilot delayed his compensation for the turbulence. The right wing of the airplane struck the rotating propeller of the parked airplane. Approximately four feet of the right wing separated from the landing airplane. The pilot applied full power and continued to a nearby airport and landed without further incidence.
