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.
