Accident Overview
A mid-air collision occurred at an altitude of 50 to 75 feet over the threshold of Runway 2. The aircraft involved were a Cessna 150, registration N5958J, and a Grumman 164B, registration N8407K. The Cessna pilot was a solo student practicing touch-and-go landings and was on final approach to Runway 2. The Grumman pilot had entered the airport environment from the north and was spraying a herbicide on the edges of the runways for weed control.
Pilot and Witness Accounts
The student pilot saw the Grumman while in the traffic pattern and initially thought it was departing from Runway 11. After that, he did not see the Grumman again. The Grumman pilot stated that as he approached the airport, he announced on the UNICOM frequency that he would be spraying the west side of Runway 20 and on Runway 11. However, neither the student pilot nor two witnesses who were monitoring the UNICOM frequency heard the Grumman pilot announce his intentions. The Grumman pilot reported that he neither saw nor heard the Cessna in the traffic pattern. The two witnesses verified that the student pilot had announced his position around the pattern.
Sequence of Events
The collision took place at low altitude over the runway threshold. The Cessna was conducting touch-and-go landings, while the Grumman was engaged in herbicide spraying operations. The lack of effective communication and visual acquisition between the two pilots, despite the student's position reports and the Grumman pilot's claimed announcement, led to the collision. No further details about injuries, damage, or post-collision events are provided in the source.
