What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot stated that the cowling gasket came loose allowing outside air to enter the cockpit. The outside air rushing into the cockpit and blowing on to the pilot's face distracted him. Upon landing downwind on rw 03, the aircraft touched down slightly left of the runway centerline at about 70 mph, and the plane ground looped to the left colliding with two runway lights and a runway identification sign.
