The world’s best bush plane is destroyed on take off in Reno, Ars Technica

           

  

Mike Patey, the Utah entrepreneur who transformed his Polish-built Wilga 2000 short takeoff and landing (STOL) aircraft into a million-dollar “ultimate bush plane“called DRACO, crashed on takeoff leaving the Reno National Championship Air Races on Monday.

Patey was attempting to depart Reno ( where DRACO had been featured in a static display) the day after the races were over, seeking to beat a fast-moving weather front. With him aboard DRACO were his wife and best friend. All three escaped the crash without injury.

The incident

The crash occurred at about 10: 12 pm local time. According to the Meteorological Aerodrome Report (METAR), the winds at Stead Airport were out of the southwest, blowing steady at 24 knots (28 mph, or about 45 km / h) and gusting to (knots) 44 mph, or about (km / h). Patey was taking off on runway 26 with a crosswind from his left.

Taking off in a significant crosswind in a relatively light airplane like DRACO — which weighs about 2500 lb or about 1100 kg — is difficult under the best circumstances. Taking off in a howling crosswind, as Patey himself acknowledged, was not a good idea. Almost immediately after walking away from the crash with his wife and best friend, Mike Patey filmed and uploaded a YouTube video, acknowledging his mistake and demonstrating both his clarity of mind and his character.

The accident was a basically a “ground loop, “wherein an airplane exhibits a rapid and uncontrolled pivot away from its intended direction of takeoff or landing. Tail-dragger airplanes — that is, airplanes with the main gear in front and a tail wheel behind — are particularly susceptible to ground looping.

Prior to the takeoff roll, the video shows DRACO being pushed by the wind down onto its right main gear. The suspension travel of the trailing-link gear (which Patey recently improved) allows it to squat for off-runway, back-country landings. In these conditions, the gear’s functioning aggravated the crosswind effect, with the left wing high and the right wing down even before takeoff.

Patey says he actually considered turning the airplane across the runway, into the wind, before takeoff but elected not to various reasons. DRACO was then hit by a gust while Patey accelerated, which lifted the left wing further and took control out of Patey’s hands.

“When that [left] wing lifted up, I had enough aileron and rudder [control]. I kicked [rudder] into it, trying to hold it and get the nose into the wind. I just about had it… .And then I had a wind bump like nothing I’ve ever felt. It lifted that left wing and turned the belly directly to the wind. I had no aileron control… I’ve never felt like a kite in my life, “he told Ars.

DRACO pivoted, skidded and half-rolled gently into the desert sand adjacent to the runway. Patey said the impact was (fortunately) smooth, and he crawled out of the airplane via the left door, which had torn off. His wife and friend exited the airplane as well.

The dragon that was…

Patey named his airplane “DRACO” from a Latin-derived word meaning dragon or serpent. He re-designed and re-built the Wilga in early 2018 by himself in (five months) – an amazing feat for one man.

Unfortunately, DRACO appears to be a write off. Both wings sheared at the root; the left main gear collapsed and is possibly torn off; the custom propeller’s blades are gone; the turbine engine almost certainly damaged; the fuselage is likely twisted; and the horizontal stabilizer on the tail has been displaced. Reconstituting such a unique airplane would be a difficult mountain to climb.

DRACO debuted at the world renowned EAA Fly-In at Oshkosh in July 2018. It became an instant phenomenon, known not only to aviators and aviation enthusiasts but to a large chunk of the general public as well. It featured in aviation and general interest publications and showed up in numerous videos — including aGoPro promotional videowith wingsuit jumpers

The airplane was essentially a different kind of extreme bush plane with a turbo-prop. Its STOL performance, altitude, cruise, and payload capabilities were unlike just about anything outside current military aircraft. In DRACO, Patey won the most prestigious STOL competitions in the world, including the High Sierra Fly-In and the Valdez STOL Competition. Patey set a bar so high that DRACO was essentially ruled out of further competition. That, in part, is why Patey has embarked on a new STOL airplane project that he calls “Scrappy,” which will be unveiled soon.

Patey admitted that the accident was his fault alone and that it will “haunt him for a long time,” but he and his family are safe.
