This is the shocking moment a light aircraft crashed near an airport in Montana.

The pilot of the Beechcraft B35 Bonanza was reportedly returning to Helena Regional Airport and approached the airfield from the north when the incident occurred on July 23.

He was initially cleared to land on runway 27 but requested runway 17 instead, as it aligned more conveniently with his route from Great Falls International Airport.

Approximately five miles from the airfield, the pilot allegedly slowed the aircraft, lowered the landing gear, and pulled the throttle all the way back. He later stated that he did not recall adjusting the propeller speed.

Believing he was too high on approach, he extended the flaps fully - a procedure he noted was not part of his usual routine.

CCTV footage shows the aircraft, operated by Peace Sign LLC, crashing on a road at around 10:03 pm local time.

An incident report from the Aviation Safety Network stated: 'During the landing flare, he waited for the aeroplane to settle onto the runway. He realised that the aeroplane had not touched down as it passed the midpoint of the 2,989ft-long runway and initiated a go-around.

'During the go-around, the pilot initially thought he had pushed the throttle control full forward, but when 'nothing happened', he looked down and realised he had pushed the mixture control forward.

'He added throttle and felt the aeroplane pick up speed. The pilot recalled that he pulled the yoke back to clear the airport perimeter fence and felt the aeroplane climb. The pilot stated that he had a positive rate of climb and thought he was high enough to begin a left turn and considered raising the flaps and contacting the tower when the aeroplane impacted the ground and slid into a building.'

Authorities said the aircraft reached around 20ft above ground level before the left wing dropped, causing the plane to descend rapidly. It struck a road and then slid into a building, resulting in substantial damage to both wings.

The pilot reported that there were no mechanical failures or malfunctions before the crash that would have affected the regular operation of the aircraft.

The National Transportation Safety Board (NTSB) released its final report on September 26, identifying the probable cause as the pilot's failure to properly configure the aircraft during the go-around, which led to an aerodynamic stall at low altitude after exceeding the critical angle of attack.

Both occupants survived the crash without fatal injuries.
