On October 25, 2016, about 1415 central daylight time, a Boeing model A75N1 (PT17) single-engine vintage biplane, N48182, was substantially damaged when it impacted terrain during a takeoff from McCampbell-Porter Airport (TFP), Ingleside, Texas. The airline transport pilot was not injured. The airplane was registered to American Airpower Heritage Flying Museum and operated by Commemorative Air Force under the provisions of 14 Code of Federal Regulations Part 91. Day visual meteorological conditions prevailed for the personal flight that departed Mustang Beach Airport (RAS), Port Aransas, Texas, about 1300, and was operating in the traffic pattern at TFP when the accident occurred.

The pilot reported that he was practicing takeoffs and landings on runway 13 (5,000 feet by 75 feet, asphalt) with a surface wind slightly left of the runway heading between 5-7 knots. He made two uneventful stop-and-go landings before the accident takeoff. The third takeoff was uneventful until the tail became airborne, around 45 miles per hour (mph), and the airplane began to veer to the right. He responded by reducing right rudder input and applying back stick pressure to become airborne at 65 mph. The pilot reported that upon liftoff, the airplane yawed right as if it had weathervaned into the wind (despite the wind being left of centerline). In response, he reduced aircraft pitch to accelerate, but the airplane continued the right yaw and entered a right roll with a slight nose-up pitch attitude. The pilot reported that he was unable to regain control with full left aileron and left rudder inputs. The airplane impacted terrain, off the right side of the runway, in a right wing low attitude. The pilot estimated that the airplane had reached a right bank angle of about 90-degrees when the right wing impacted the ground. The airplane subsequently nosed over and came to rest inverted. The airplane sustained substantial damage to the upper wing and empennage during the impact sequence.

At 1415, the TFP automated surface observing system reported: wind 070 degrees at 11 knots, clear sky, 10 mile surface visibility; temperature 31 degrees Celsius; dew point 18 degrees Celsius; and an altimeter setting of 30.10 inches of mercury.
