A mystery aircraft has been reported buzzing over a Sacramento community for weeks, annoying residents.

The light plane has been flying in "regular patterns day and night for weeks over parts of Sacramento," according to ABC's Sacramento affiliate, KXTV.

Arden Park resident Richard King found a tracking map on FlightRadar24.com, in which the website captures the plane flying in an almost perfect circle on the evening of March 8.

Federal Aviation Administration spokesman Allen Kenitzer initially told ABC News that the plane was likely a T-38 military training aircraft performing pattern work - but then later said he was referring to a different plane, the result of a miscommunication.

"We don't know the purpose of the flights," he said. "If an aircraft is operating in uncontrolled airspace, there's no requirement to talk with air traffic [control]."

Editor's note: An earlier version of this story incorrectly said a mystery plane annoying Sacramento residents had been identified by the FAA as a military plane conducting training exercises. However, an FAA official later said he likely was referring to a different plane than the one the residents complained of, the result of a miscommunication.
