This spatial disorientation accident involved a Cessna Citation CJ4 departing from Burke Lakefront Airport. Jason Schappert reviews the event, the human factors involved, and the safety lessons that can strengthen future aeronautical decision-making.
Sequence of Events After Takeoff
The aircraft departed at night over Lake Erie in marginal VFR conditions that transitioned into IMC. Shortly after liftoff, altitude alerts sounded, followed by warnings related to excessive bank angles and sink rate. Several radio calls from the pilot were never transmitted because the push-to-talk switch was likely not pressed. Multiple pull-up warnings followed until the end of the recording.
The Role of Spatial Disorientation
The aircraft entered IMC immediately after departure over a featureless and dark environment. The combination of darkness, water, and cloud layers created a high risk of spatial disorientation. The FAA outlines sensory illusions and their dangers in its Spatial Disorientation Education Page, reinforcing how quickly confusion can develop when outside references disappear.

Pilot Experience and Contributing Factors
The pilot held significant flight time, including experience in a Citation Mustang. However, only 56.5 hours were logged in the CJ4. Records also showed the pilot had been awake for 17 hours, raising fatigue concerns. The NTSB noted negative transference between aircraft types. Autopilot operation differed between the Mustang and CJ4, and the pilot may have believed the autopilot was engaged when it had not.
Avionics and Aircraft Differences
Transitioning from Garmin-equipped aircraft to Collins Pro Line systems can introduce workload and adaptation challenges. Autopilot controls, annunciation cues, and operational logic differ across platforms. The NTSB concluded that confusion over these systems may have contributed to the aircraft entering an uncontrolled attitude without timely correction.
Demonstrating Spatial Disorientation
To illustrate the dangers of spatial disorientation, Jason conducted in-flight demonstrations with a student preparing for solo. These exercises showed how easily the human vestibular system can misinterpret motion, especially in environments where the horizon blends with surrounding terrain. Even inexperienced deviations quickly reached bank angles far greater than expected.
Why Trusting Instruments Matters
Jason emphasized that instrument scanning and trust in flight instruments remain essential. Pilots who rely on physical sensations can quickly become disoriented. The demonstration highlighted how closing visual references creates illusions similar to those encountered in actual IMC.
Lessons Learned from the Event
This spatial disorientation accident highlights the need for disciplined instrument scanning, proper avionics familiarization, and fatigue awareness. Human factors, workload transitions, and environmental conditions all play major roles. Studying such events helps pilots recognize early cues and break potential error chains before they escalate.
