What aircraft was involved and where did it happen?

The accident on 1996-09-16 involved a FQZC Bellis, Alberta, operated by Spiral Cessna 150 C, at CA.

What was the probable cause of the accident?

The pilot continued flying into worsening weather conditions, which likely led to spatial disorientation and an unrecoverable spiral dive.

Fatal night flight accident involving Cessna 150 in Alberta

A pilot flying a Cessna 150 lost control of the aircraft during a night flight through deteriorating weather, resulting in a fatal spiral dive.

What happened

A night visual flight rules (VFR) flight from Spirit River, Alberta, to St-Paul ended in a fatal accident when a Cessna 150 struck the ground in a high-speed spiral dive. The pilot departed Spirit River at approximately 20:40 MDT after receiving a weather briefing and filing a flight plan with the Grande Prairie Flight Service Station. No radio communications were received from the aircraft during its progress along the route.

At approximately 23:10, residents near a farm heard an engine whine followed by a heavy impact. Despite heavy rain hindering immediate search efforts, authorities located the wreckage about a quarter-mile from the farmhouse the following morning. The pilot sustained fatal injuries.

The investigation

The investigation examined the aircraft's mechanical condition and the pilot's training history. The Cessna 150 was found to be well-maintained, with no evidence of mechanical failure in the engine, radio, or GPS systems. Propeller damage indicated the engine was producing significant power at the moment of impact. The aircraft struck the ground in a nose-down, right-wing-low attitude, with an airspeed indicator showing speeds exceeding 190 mph.

The pilot's training included a private license and a night endorsement, but only 11 hours of simulated instrument training had been completed. Most of this training occurred in well-lit urban areas, such as Edmonton, and did not involve actual instrument meteorological conditions.

Weather analysis revealed that a maritime cold front was moving through the region. While conditions were clear at departure, the flight path encountered low ceilings, fog, and rain. The investigation also noted that the emergency locator transmitter (ELT) failed to transmit a signal immediately following the crash, though it functioned normally after the switch was reset.

Findings

The pilot attempted to maintain visual flight despite deteriorating weather conditions.
The accident occurred at night over a sparsely populated area with low visibility, which obscured the natural horizon and surface references.
The pilot had limited experience flying solely by reference to instruments.
The pilot likely became spatially disoriented due to the loss of visual references, leading to a loss of aircraft control.
