Midair Collision Between Training Airplane and Helicopter Kills Two During Landing Practice

October 1, 2021 — Piper PA-28-181 N2868H and Robinson R22 N412TL — Chandler, Arizona

Two training aircraft were using the same airport environment when the Piper descended into the helicopter. The airplane had been warned about helicopter traffic, yet its instructor chose to conduct a simulated engine-failure approach and later used a forward slip to increase the descent rate. The helicopter was operating a parallel traffic pattern. The two aircraft collided near Chandler Municipal Airport, killing both helicopter occupants.

Two different training patterns converged at low altitude

The Piper PA-28-181 N2868H and Robinson R22 N412TL were operating around Chandler Municipal Airport on October 1, 2021. The helicopter was using a tighter, lower pattern associated with a parallel taxiway while the airplane was working the runway pattern. Their paths converged at low altitude.

The airplane was conducting instructional pattern work and the approach included a simulated engine-failure maneuver. The helicopter was also in instructional operations. The collision destroyed the R22 and killed both people aboard it. The airplane survived the impact but lost a main-gear component and landed.

The investigation had to reconstruct two aircraft operating in different patterns rather than a single shared circuit. Their expected altitudes, lateral positions and maneuvering instructions were therefore material to understanding how the collision developed.

The public sources reviewed here do not provide a final NTSB probable-cause sentence that can be safely attributed to this event. the report therefore does not assign a final cause beyond the documented collision sequence.

The aircraft configurations also affected the collision outcome. The R22 was destroyed and both helicopter occupants died. The Piper survived the collision sufficiently for its occupants to land after the airplane lost its left main landing-gear component. Public reporting confirms that the two aircraft were training aircraft operating in the same airport environment, but the sources consulted for the report do not provide a completed final causal finding. That limitation is retained rather than replacing it with a simplified claim about pilot or controller error.

The different pattern altitudes are important to the flight because the helicopter and airplane were not expected to occupy identical tracks. The helicopter was using a lower, tighter pattern while the fixed-wing airplane was approaching the runway. The collision nevertheless occurred within the same airport traffic environment, showing how quickly two training operations can converge when their expected separation breaks down.

The public record also confirms that the airplane occupants survived the collision while the helicopter occupants did not. The different outcomes followed from the damage sustained by the two aircraft and the location of the impact. No later causal theory is needed to establish those facts.
