The pilot of a Piper PA-36-375 was attempting to land and he collided with a Grumman AA-5B, which had just touched down on the same runway. When the pilot of the Piper heard the collision, he noticed the wings of the Grumman below his airplane. He then executed a go-around, and diverted to another airport. The pilot of the Piper reported only minor damage to his airplane's propeller. The pilot of the Grumman reported damage to his fuselage, empennage, and wing structures. There was no Unicom installed or in use at the airstrip. Both pilots reported that they were not transmitting on any aircraft radio frequencies prior to the accident.

History of flight

On April 5, 2003, about 1045 Pacific standard time, a Piper PA 36-375, N3859E, collided with a Grumman American AA-5B, N28821, while both airplanes were attempting to land at Bottimore Ranch Airport (65CN) near Herald, California. San Joaquin Air was operating the Piper under the provisions of 14 CFR Part 137. The owner/solo student pilot was operating the Grumman under the provisions of 14 CFR Part 91. The airline transport pilot, the sole occupant of the Piper, and the student pilot, the sole occupant of the Grumman were not injured. The Piper sustained minor damage; the Grumman sustained substantial damage. The Piper departed on a local aerial application flight at about 1015 from 65CN,. The Grumman was a local instructional flight that departed Kingdon Airpark (O20) Lodi, California, about 1015 en route to 65CN,. Day visual meteorological conditions prevailed; neither pilot had filed a flight plan. The primary wreckage was at 38 degrees 18 minutes north latitude and 121 degrees 15 minutes west longitude.

The pilot of the Piper said that while he was attempting to land at 65CN, he collided with the Grumman, which had just touched down on the same runway. When the pilot of the Piper heard the collision, he noticed the wings of the Grumman below his airplane. He then executed a go around. Because the Grumman was on the runway at 65CN, the Piper elected to fly to Franklin Field Airport (Q53), Franklin, California. The pilot of the Piper then returned to 65CN via automobile.

The pilot of the Grumman said that while he was landing at 65CN, just after the main landing gear had touched down, "the aircraft went all over the place." He said that he did not know that he had been hit by another airplane until he saw the Piper flying away from him.
