( CNN ) -- For the third time this weekend , U.S. jet fighters on Sunday intercepted a small private plane that violated restricted airspace in the area of Camp David , Maryland , while President Barack Obama stayed there , the North American Aerospace Defense Command said . Two F-15E fighters under NORAD control intercepted a Cessna 182 civilian aircraft on Sunday morning and led it out of the temporary restricted area , according to a NORAD statement . The Cessna landed at the Carroll County Regional Airport , the NORAD statement said . On Saturday , two similar incidents occurred involving other aircraft that violated the restricted area around the presidential retreat , a NORAD spokesman confirmed . There was no extra security threat involved in any of the incidents beyond the violation of the temporary restricted area . Authorities attribute the multiple violations to the temporary expansion of restricted airspace around Camp David when Obama is there . According to the Federal Aviation Administration , the temporary flight restriction in the Camp David area this weekend was scheduled to last from noon Saturday until 6 p.m. Sunday .
NORAD scrambles jet fighters twice on Saturday , once on Sunday . The first time they scrambled was to intercept a Russian plane that had just crossed the border into Ukraine and then flew back over Russia.
