On April 6, 1997, at 1400 Pacific daylight time, N45WA, a home built Allen-Wayne Pitts S-1E airplane, operated by the owner/pilot, collided in flight with N4100U, a Cessna 150D, registered to Sky Valley Aviators, at the Arlington Municipal Airport in Arlington, Washington. The Pitts S-1E was approaching to land while the Cessna 150D was climbing out after takeoff from the same runway. Visual meteorological conditions prevailed and no flight plan had been filed by either pilot. The commercial pilot of the Pitts S-1E, the sole occupant, was on a personal flight and received minor injures. The student pilot of the Cessna 150D, the sole occupant, was on an instructional flight (supervised solo) and received minor injuries. The Pitts S-1E was substantially damaged, while the Cessna 150D was destroyed and caught fire after impact. Both flights were conducted under 14 CFR 91.

According to ground witnesses and pilot statements (attached), the student pilot taxied onto runway 34 after visually checking for other airplanes in the traffic pattern and announcing his intentions to take off over the airport's common traffic advisory frequency (CTAF). Meanwhile, the pilot of the Pitts S-1E was on final approach with the intention of performing his second touch-and-go landing on runway 34. As the Cessna 150D was climbing through about 30 feet above the ground after takeoff, the Pitts S-1A descended into the tail of the Cessna 150D. The Pitts continued downward and impacted the runway on its main landing gear. The Cessna was observed to pitch up, "flip over," and impact the runway in an inverted attitude. Both pilots stated that they did not see each other prior to the collision, nor did they hear each other over the CTAF. Witnesses stated that they heard the Pitts S-1A pilot announce "turning base to final," for a landing, and other witnesses heard the student pilot announce his intentions to take off from the same runway. No preimpact mechanical malfunctions were reported by either pilot.

The student pilot further stated that he had made three take-offs and landings with his father prior to the accident. The student's father was also his flight instructor. His father then got out of the airplane and told his student to take off and land again; it would have been the student's second supervised solo flight.

The student stated that he taxied to the active runway and looked out for other airplanes in the traffic pattern. He also performed a 360-degree turn on the taxiway to spot other traffic. He stated that he saw a "... tow plane on final and another airplane on final..." and he waited for both to land. Then he looked again and observed a "... Cessna on base, but he was far enough away..." He stated that he made a "radio call" announcing that he was departing from the active runway, and he began his takeoff. Right after liftoff, the student pilot "... felt a real sharp hit..." and then became "upside down." After he impacted the runway, a fire erupted, so the student pilot extricated himself from the airplane.

The student pilot reported that he had logged a total of 30.9 hours of flight time, including 16.6 hours during the previous 90 days. He carried an FAA Third Class Medical Certificate dated January 9, 1997, and a solo flight endorsement dated March 24, 1997.

The commercial pilot who was in the Pitts stated that he had departed from Paine Field in Everett and had been performing aerobatic maneuvers prior to the accident. He then entered the traffic pattern for some touch-and-go landings on runway 34 at the Arlington Municipal Airport. He stated that he observed three airplanes in the pattern, including his airplane, and that he was the third one in sequence to land for his second touch-and-go. The Pitts pilot stated that he "... announced his downwind and his turn from base to final" over the CTAF. He further stated:

The first airplane in the pattern, the red airplane, landed on [runway] 34. The second airplane (a tow plane) landed in the grass adjacent
