What happened
A flight intended to pick up passengers ended in a fatal accident after the pilot transitioned from instrument flight rules to visual flight rules while 33 miles from the destination. While cruising at 3,300 feet, the pilot informed air traffic control that the destination airport was in sight and subsequently cancelled his IFR clearance. In the following 13 minutes, radar tracking showed the aircraft type performing erratic maneuvers, including 360-degree turns and significant altitude fluctuations between 4,000 and 900 feet, moving away from the intended airport.
The pilot later re-established contact with controllers, stating he could no longer see the airport and requesting an instrument approach. During this period, the pilot struggled to follow heading and altitude assignments and requested assistance with identifying the initial approach fix. The radar track showed the aircraft climbing before entering a descending right turn at 2,500 feet and 180 knots, at which point radar contact was lost. There were 0 fatalities reported in the source text, though the aircraft was destroyed. The engines were found to be at high power at the time of impact, and no mechanical failures were identified as the cause.
Findings
Investigation into the accident highlighted several critical factors. The pilot's decision to cancel IFR clearance while far from the destination, despite being in an area with low ceilings and restricted visibility, likely led to spatial disorientation. This disorientation was exacerbated by increased workload as the pilot attempted to manage navigation radios and expired GPS databases.
Additionally, several contributing factors were identified:
- The pilot's decision-making was likely impaired by the presence of ethanol, amphetamines, opioids, antihistamines, and marijuana in his system.
- The aircraft was operating past its required maintenance inspection intervals.
- The pilot failed to file an alternate airport despite weather conditions that warranted it.
- The use of expired navigation and obstruction databases on the onboard GPS hindered effective navigation.
