Cessna 150 and Cessna 525 Citation Runway Collision at Marion Municipal Airport, Indiana

On April 2, 2018, a Cessna 150 and a Cessna 525 Citation jet collided on the runway at Marion Municipal Airport in Marion, Indiana. The collision occurred during a takeoff attempt and resulted in two fatalities among the Cessna 150 occupants, while no injuries were reported among the five occupants aboard the Citation. Federal investigators examined the runway incursion sequence, communications, and airport environment factors that may have contributed to the collision.

Accident Summary

What Was Reported at the Scene

Early reporting indicated that the collision occurred during a takeoff attempt involving the Cessna 150 and that the Cessna 525 Citation sustained significant structural damage, described as the tail being sheared off. The five occupants aboard the Citation were reported uninjured. The Cessna 150 occupants were reported to be local firefighters and were fatally injured.

Aircraft and Operational Context

A runway collision involving dissimilar aircraft typically prompts investigators to examine the sequence of runway movements, whether each aircraft was authorized to enter or use the runway, and what information was available to pilots at the time. Marion Municipal Airport is a general aviation airport environment, and runway collision analysis often considers airport geometry, sightlines, signage and markings, traffic pattern procedures, and radio communications.

The aircraft involved represent very different performance categories. A Cessna 150 is a small, single-engine piston training aircraft, while a Cessna 525 Citation is a business jet with higher acceleration and takeoff performance. In mixed-traffic environments, investigators often consider how performance differences can compress decision-making timelines and increase the importance of clear sequencing and situational awareness during runway operations.

Accident Investigation

The National Transportation Safety Board opened an investigation into the runway collision. NTSB investigations commonly involve scene documentation, wreckage examination, review of radio communications, and evaluation of airport procedures and surface movement factors. A general overview of how federal investigations proceed is provided in our discussion of the NTSB investigation process.

In runway collision events, investigators often focus on (1) communications and traffic advisories, (2) pilot actions and situational awareness, (3) runway use and sequencing, (4) whether there were any constraints involving visibility, glare, or weather, and (5) airport surface markings and signage. Where available, investigators may also evaluate ADS-B or other tracking data, witness accounts, and airport surveillance information to reconstruct the timing and relative positions of the aircraft.

Operational and Regulatory Issues

Runway collisions can raise questions about local operating practices, compliance with standard traffic pattern procedures, and whether pilots had sufficient information to avoid conflicting runway use. Investigators may examine whether any procedural changes, advisory practices, or airport safety enhancements are warranted based on the collision sequence and the runway environment.

Where two aircraft are operating in proximity on the airport surface, investigators may evaluate whether runway incursion risk factors were present, including simultaneous operations, ambiguous communications, or limitations in visibility from cockpit perspective. The investigative record typically develops through factual findings rather than early assumptions about fault.

Aviation Accident Litigation

Runway collision accidents can involve complex technical and operational questions, including airport operations, communications, procedural compliance, and the interaction between pilot decision-making and airport environment factors. A general overview of how these matters are evaluated is provided in our discussion of aviation accident litigation.
