Incident
A Piper Cherokee and a Piper Aztec collided in midair while operating in the vicinity of an airport. The Cherokee was in the traffic pattern performing touch-and-go landings, and the Aztec was inbound to the airport. The collision occurred in controlled airspace, and both aircraft were under the control of the local controller at that time.
Controller Shift
A shift change at the control tower took place a few minutes before the midair collision. The relieving local controller declined to receive a formal briefing from the outgoing controller regarding the location of traffic. The reason given by the relieving controller was that he was too busy to accept the briefing.
Aircraft Involved
The two aircraft involved in the collision were a Cherokee and an Aztec, both models manufactured by Piper. The Cherokee was conducting touch-and-go landing exercises, while the Aztec was arriving at the airport.
