A Cessna 208B Grand Caravan crashed on the roof of an industrial building in Heyburn, Idaho, USA, while attempting to land at Burley Municipal Airport, ID (BYI). The pilot suffered fatal injuries.
The aircraft departed Salt Lake City International Airport, Utah (SLC) at 07:00 hours local time (13:00 UTC) on a cargo flight to BYI.
The pilot aborted the first approach to runway 20 at BYI at 08:11. The pilot executed the published missed approach procedure and reported over IREME.
The controller then cleared the pilot for another RNAV approach to runway 20. After the pilot reported that she had crossed the initial approach fix, the controller approved a change to BYI advisory frequency.

According to a witness, the aircraft descended out of the clouds and then immediately went into a steam cloud, which was produced from a set of six smokestacks located on the roof of a processing plant. The witness heard the engine increase in sound and saw the nose lift shortly before the airplane struck the smokestack and descend to the rooftop.

The aircraft crashed 700 m north-east of the threshold of runway 20. At the time of both approaches, visibility at the airport was limited due to snowfall.

The pilot’s failure to maintain altitude during an instrument approach, which resulted in a descent below the approach path and impact with a vent stack. Also causal was the failure of the processing plant to correctly paint the vent stacks, which had been determined by the FAA to be a hazard to navigation due to their proximity to the landing approach path. Contributing to the accident was the likely distraction/illusion/obscuration created by steam from the processing plant, which intermittently obscured the runway.
