Analysis 

The accident airplane was the trailing airplane in a flight of two landing on runway 36L at Experimental Aircraft Association AirVenture when the accident occurred. The pilot reported that, while on final approach, he heard an air traffic control transmission telling a canard airplane to land on runway 36R. Mistaking the transmission for 36L, the pilot stated that he began to look for the canard airplane, which diverted his attention from the lead airplane and resulted in a loss of separation. As he approached the lead airplane's right wing, he reduced the engine power and pitched up to slow his airplane. He stated his airplane banked "hard to the right;" he corrected by banking to the left, which, combined with the airplane's nose-high pitch attitude, resulted in an aerodynamic stall.

Although the pilot stated that he was directly behind and below the lead airplane, and encountered the airplane's wake turbulence and prop wash, a GoPro camera mounted on the left wing of the accident airplane showed that the airplane remained behind and above the lead airplane; therefore, it is unlikely that the accident airplane encountered wake turbulence. The GoPro footage was consistent with the accident airplane slowing then subsequently experiencing an aerodynamic stall. It is likely that the pilot slowed the airplane excessively as he attempted to maintain separation and exceeded the airplane's critical angle of attack.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's exceedance of the airplane's critical angle of attack on short final approach, which resulted in an inadvertent aerodynamic stall and subsequent loss of control. Contributing to the accident was the pilot's distraction with other traffic in the area.

Findings

Aircraft
Angle of attack - Not attained/maintained (Cause)
Airspeed - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)


Factual Information

On July 24, 2016, at 1805 central daylight time, a BRM Aero S R O, Bristell E-LSA, collided with the terrain following a loss of control while landing at the Wittman Regional Airport (OSH), Oshkosh, Wisconsin. The pilot received serious injuries. The airplane was substantially damaged. The aircraft was registered to Sport Flying USA, Inc., and was operated by an individual under the provisions of 14 Code of Federal Regulations Part 91 as a business flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The last leg of the cross country flight originated from the Watertown Municipal Airport (RYV), Watertown, Wisconsin, at 1630.

The airplane was the trailing airplane in a flight of two that were landing on runway 36L at OSH during Experimental Aircraft Association AirVenture. The pilot in the lead aircraft stated they were cleared to land on the purple dot. The purple dot was located 3,052 ft down the 8,002 ft long runway. He did not see the accident occur.

The accident pilot stated he turned onto final approach for runway 36L, and was established with 20 ° of flaps at 65 knots. He then heard an air traffic transmission telling a canard airplane to land on runway 36R not 36L. The pilot stated he began to look for the canard airplane which took his attention off the lead airplane resulting in a decrease of the separation between the airplanes. He stated he got within 10 ft of the lead airplane's right wing at which time he reduced the engine power and pitched up to slow his airspeed. The pilot stated that was then directly behind the lead airplane and below his altitude, when he encountered the lead airplane's wake turbulence and prop wash, and his airplane banked "hard to the right". He corrected by banking to the left, but must have had back pressure on the stick and the airplane stalled. The pilot stated he was about 150 ft above the ground when the loss of control initially occurred.

Witnesses reported the airplane was low and slow as it approached the runway. They stated it stalled, rolled left, and descended to impact with the terrain.

A GoPro camera was located amongst the wreckage. The 128GB Micro SD card was retrieved from the camera and downloaded by the National Transportation Safety Board (NTSB) Vehicle Recorder Laboratory. It was determined that the camera was mounted on the left wing. A summary of the video was prepared and is attached to this report. The lead airplane was visible in front of the accident airplane as they approached the airport. At one point while the airplanes were descending and approaching the airport, the accident airplane was about the same altitude as the lead airplane. Both airplanes then made a left turn [onto base leg] at which time at least two other airplanes were visible in the distance ahead of the lead airplane. At this point the lead airplane was below the altitude of the accident airplane. Both airplanes then made another left turn onto final approach. About 27 seconds after the accident airplane was established on final approach, the distance between the accident airplane and the lead airplane began to reduce. Other than the lead airplane, no other flying airplanes were visible on approach to either runways 36L or 36R. The distance between the two airplanes continued to reduce. The lead airplane was at or below the attitude of the accident airplane until the accident airplane entered a left bank and began to descend. The left bank continued to increase such that the airplane was nearly inverted as it descended to ground impact.

The air traffic control audio recording was reviewed by the NTSB Investigator-in-Charge. At 03:00 [lapsed recording time, minutes (MM): seconds (SS)], the controller cleared a canard airplane to land on runway 36L. About 31 seconds later, the controller changed the canard's landing runway to 36R. At 04:04, a second canard pilot requested landing on runway 36R and 14 seconds later, it was cleared to land on runway 36R. About 15 seconds later, the controller cleared the accident airplane and his lead airplane to land on runway 36L. At 04:42, the controller instructed the canard airplanes to keep rolling to the end of the runway. At 05:00, the accident is announced over the radio.

A damaged SD card from a Garmin GPS was also retrieved from the wreckage and sent to the NTSB Vehicle Recorder Laboratory. The card was cracked through its memory chip which prevented data recovery from the card.

OSHKOSH, Wis. (AP) — A pilot suffered injuries that were not life threatening when his small plane crashed at the Oshkosh airport.

Thirty-nine-year-old Richard Maisano of Pennsylvania crashed at Wittman Regional Airport after his HXA-Bristell Light Sport stalled on Sunday. 

Experimental Aircraft Association spokesman Dick Knapinski says Maisano was taken to a Neenah hospital after the crash. 

Federal Aviation Administration Great Lakes Region spokesman Tony Molinaro told USA Today Network-Wisconsin that Maisano was the only occupant in the aircraft when it stalled as it approached the runway.

Oshkosh is hosting the EAA Airventure air show this week. 

The airport was briefly closed Sunday night after the crash.

The Federal Aviation Administration is investigating.

OSHKOSH, Wis. (WBAY) – A plane accident during a landing at Wittman Regional Airport in Oshkosh caused a pilot to be transported to the hospital Sunday evening.

EAA Airventure spokesman Dick Knapinski says the pilot was in a small aircraft when it went down the south end of the north-south runway. It did not go off the runway.

The pilot was conscious and alert after the accident and is now fine, Knapinski said.

The accident caused the airport to temporarily close. However, the east-west runway reopened around 7 p.m. before the entire airport closed at its scheduled time an hour later. The the north-south runway remained closed after the accident.

Wittman Regional Airport has two main runways.

Planes that were scheduled to land at Wittman Regional Airport for EAA Airventure were being diverted to other nearby airports during the time of the accident.

OSHKOSH - The main runway at Wittman Regional Airport in Oshkosh was closed today after a small aircraft came up short on the runway and crashed.

EAA spokesman Dick Knapinski says there was only one person on board and they were alert and conscious but taken to a hospital.

It happened on the north/south runway just after 6 PM.

The plane did not catch fire. 

The entire airport closed for about an hour and just after 7 PM the east/west runway reopened. 

Normally, the airport closes at 8 PM so it is unclear if it will reopen again tonight.

Knapinski says the incident will not affect opening day tomorrow for EAA Airventure.

The FAA and NTSB are currently leading the investigation into what happened.

OSHKOSH - A pilot was taken to a hospital after a small aircraft crashed early Sunday evening at Wittman Regional Airport.

The unidentified plane was arriving at the airport about 6 p.m. Sunday when it came down short of the south end of Runway 36, Experimental Aircraft Association spokesman Dick Knapinski said. A lone occupant, who was conscious and alert, was taken to a hospital with unknown injuries.

Wittman Regional Airport was completely closed for about an hour, with the east-west runways reopening about 7 p.m., Knapinski said.

It was the airport's second partial closure of the day after an aircraft touched down without its landing gear on Runway 27, Knapinski said.

EAA AirVenture Oshkosh 2016 officially kicks off Monday at Wittman Regional Airport in Oshkosh.

We were less than a half minute behind and landing on the parallel 36 R runway when the Bristell stalled about 50 feet above the ground. We were relieved to hear of his survival. A testament to the Light Sport's crash integrity.
