The video shows a stunt airplane owned by Lancaster-based Viper Airshows nearly slamming into a person with a camera on the runway of the Lancaster Municipal Airport. Someone on an all-terrain vehicle can be seen riding around in the background.
A North Texas stunt pilot shown maneuvering his biplane perilously close to people on the ground could lose his license.
Video of the incident Saturday at Lancaster Regional Airport was posted to YouTube and widely broadcast.
It shows the plane approaching the runway and then dipping to the left, its wing just a few feet from the ground. It roars past a person riding an all-terrain vehicle and another videotaping the approach.
The Federal Aviation Administration is investigating Jason Newburg, who the agency claims lacked a valid waiver. Agency spokesman Lynn Lunsford says Newburg may also have violated FAA rules that prohibit pilots from acts that endanger people and property.
He adds it's too early to determine what penalties Newburg may face.
Newburg said the video, which was recorded last Saturday, was a well-planned stunt to produce a viral video.
The voice message box at Newburg's business, Viper Airshows, was full.
