Depending on how closely you follow NASCAR and/or the EAA Airventure (a.k.a "Oshkosh") you may know that NASCAR owner Jack Roush crashed his Hawker-Beechcraft jet during arrival at the Oshkosh event. The above link is to news coverage after the fact. The NTSB report refers to amateur video of the crash, but I haven't found it posted.
The NTSB report says:
A review of amateur video taken at KOSH showed the accident airplane in a left base turn to final for runway 18R. The airplane appeared to overshoot the runway centerline during this turn and then level its wings momentarily before entering a slight right bank simultaneously as the nose of the airplane pitched up. The airplane then turned left toward the runway centerline and began a descent. During this descent the airplane’s pitch appeared to increase until the airplane entered a right bank and struck the grass area west of the runway in a nose down, right wing low attitude.
The above, eyewitness accounts on the news, and the following description of the situation from Mark Martin (Roush's friend, former driver for Roush's team, and a pilot) suggest that he was distracted by traffic and slowed the airplane too much while manoevering for the field.
Jack got in a situation where he thought, "How am I going to get out of this without hitting somebody?" Because of all the things that were going on, which is exactly what I thought would happen, because, you know, he's in a jet and there are some very small aircraft at different speeds and those kinds of things, and he just got in a situation where he was uncertain about how he was going to make it all work, got slow and tried to get slowed down and got a little too slow and whatever.
"Stall speed," the lowest possible flying speed for an airplane, increases with bank angle, so a wing that is flying straight and level may stall as soon as the airplane banks, without a reduction in speed.
Oshkosh is an incredibly busy piece of airspace during airshow week, and they do crazy things to accommodate the rate of landing aircraft. Oshkosh arrival procedures are set up for aircraft of different speeds. Pilots choose either the 90 knot stream or the 135 knot stream, but are encouraged to fly at 90 kts if they can. The way they are handled and the spacing they are required to maintain means that Roush shouldn't have been forced to tuck in behind someone in a Cessna on final approach at 55 knots. The NTSB video analysis and eyewitnesses don't mention conflicting traffic. The standard VFR arrival is a right base for a combined final to 18L/18R, with the air traffic controllers directing aircraft left and right. On the left base arrival he was supposed to turn left base directly towards the blue dot, partway down the runway. If he was late on that turn he could have put himself into conflict with arriving slower traffic. We do know his final turn was late so he was slightly past the final approach course where he was supposed to be, right of the centreline on runway 18R, further from traffic on 18L, and towards a shaded "do not fly" zone over airshow guests. I wonder if another aircraft was arriving on a right base for a different touchdown spot for 18R and that was an issue. My internet connection here isn't good enough to download the full NOTAM pdf, or to find some stall speed numbers on the airplane he was flying. The runway "18R" on which he was cleared to land is normally just 18, and runway "18L" is a taxiway the rest of the year. Amusingly the media are calling it "runway 1836" perhaps after NOTAMs or airport signs that would call the piece of pavement "runway 18-36" after its two ends.
Another source, which I don't recommend you click because it is making my computer screen flash--I think it's trying to load pop-ups--states that Mr. Roush was initiating a go around right before the crash. I think that may be just because he went to full power in an attempt to recover from the stall. Mr. Roush doesn't mention that in his description, "Basically a landing accident, based on a conflict in airspace with another airplane, after I'd been given clearance to land."
I assume he was flying with the 135 knot contingent, and not the 90 knot aircraft. I wouldn't try to do an arrival at 90 kts in my bird. It's theoretically possible, but not safe.
The article that caught my attention was this one, with a pull quote from Roush claiming that there is no FAA restriction on private pilots with monocular vision, "except maybe airline pilots." I believe one-eyed US pilots do have to demonstrate ability to compensate, but after that, they can become airline pilots.
ICAO medical standards require binocular vision, but "flexibility based on national experience may be applied," so Canada makes an exception for the licensing of monocular vision private pilots, and on a case-by-case basis, sometimes with restrictions for commercial pilots who lose vision in one eye.
This is Roush's second airplane crash. His first was a crash of an experimental homebuilt into a lake, an accident which the NTSB attributed to "the pilot's decision to fly at low altitude and his improper visual lookout resulting in an in-flight collision static with wires."
He had two car crashes as a racing driver, too. I could say he just lives fast and takes risks, but overshooting the runway centreline when he was already slowed to below his normal approach speed suggests that he didn't have exceptional control of the airplane. Considering the quantity of recording equipment and witnesses involved, there's lots to work with to determine what happened. I'll be interested to see the full report when the NTSB completes their investigation.
