flight safety detectives Episode 231 - Midair Collision Between Cessna 172 and Dash 8 Highlights Aviation Safety Concerns in Mixed-Use Airports

A fatal midair collision involving a Cessna 172 illustrates several aviation safety concerns related to pilot training in and around airports with commercial operations. The incident involved a student and instructor on board performing touch-and-go landings and a Dash 8 departing on a passenger flight.

While the event happened in Kenya, the circumstances that led to this accident could happen in any location where airliners and small training aircraft operate out of the same airport. In this case, the midair collision occurred only about 500 feet above the ground and 1500 feet below a broken cloud layer in an area with over 10 km of visibility.

The Cessna 172 was performing touch-and-go landings on from one of the airport’s runways. Shortly after the Dash 8 departed from an intersecting runway, the stabilizer of the airliner collided with the Cessna. The Cessna crashed, killing both on board. Todd Curtis and John Goglia analyze the preliminary report, which came out three months after the accident.

They examine the transcript of ATC communications around the time of the accident. Anyone who operates aircraft in similar circumstances could learn something useful from studying this event.
​
Immediately after the collision, the transcript of the ATC communications stated that during 97 seconds, there was “unrelated transmission from other traffic.” Any transmissions to or from aircraft near the collision could provide useful clues into what was known or not known by ATC and aircraft crews in the vicinity.
