Cessna 172 N2148E and Cessna 172 N3958S accident near Toms River, New Jersey

Probable cause

The failure of the Cessna 172N pilot to see and avoid a second airplane while maneuvering in the traffic pattern, which resulted in a midair collision. Contributing to the accident was the failure of the Cessna 172N pilot to tune his radio to the correct traffic advisory frequency for the destination airport.

NTSB analysis

Two airplanes, a Cessna 172E and a Cessna 172N, collided in midair while in the traffic pattern over the approach end of the runway. The pilot of the Cessna 172E announced his position while on downwind, base, and final approach to landing. The pilot of the Cessna 172N approached the airport and announced his intention on the common traffic advisory frequency to practice a simulated engine-out maneuver followed by a descent to set up for left base leg of the traffic pattern for runway 32. While about 100 ft over the approach end of the runway, the airplanes collided, with the Cessna 172N striking the Cessna 172E from above. Both airplanes landed safely, but an examination revealed that both incurred substantial damage to their right wings. The radio in the Cessna 172N was found tuned to the wrong frequency. It is likely that the pilot of the Cessna 172N thought he switched the radio to the correct frequency and failed to maintain an adequate visual lookout, which resulted in a midair collision on short final. Because his radio was tuned to the wrong frequency, his transmissions were not heard by other pilots in the vicinity of the airport and he was not able to hear other traffic callouts.
