Near miss at Denham
TWO light aircraft that came within 220 yards of colliding at Denham Airfield avoided a crash when one pilot spotted the danger at the last minute, a report has revealed.
The Pilatus PC12 and Cessna C152 were on a collision course over the airfield last May, the UK Airprox Board ( UKAB) report says.
According to the BBC, the Pilatus pilot saw the Cessna “very close” on his right and turned left.
The C152 pilot said he saw the gold aircraft 150200m away but did not have time to take avoiding action.
UKAB said chance had played a large part in the two planes coming so close at an altitude of about 1,000ft, just after 9am on May 23, but the PC12 pilot “flew into conflict” with the C152.
The board said it was “unfortunate” the PC12 pilot had not seen the C152 earlier, but it was “fortunate” he did eventually see it, albeit at close range.
“UKAB said both pilots shared equal responsibility for avoiding the collision, but the C152 pilot, who was instructing a student at the time, had right of way.
He had recorded “high risk” of collision.
“With a combination of a late sighting, relatively high overtake speed, and reported hard turn away, it was also agreed that separation had been reduced to the minimum, and that chance had played a major part in events,” the report said.
