MANHATTAN, Kan. (AP) _ The Federal Aviation Administration has revoked the operating certificate for Capitol Air Service Inc., a commuter and air taxi service whose certificate was suspended for seven days in March.

The emergency revocation order, issued Friday, cited violations of FAA regulations, including inadequate records of crew training and flight and duty time, said John Swank, an FAA spokesman.

The order also cited apparent falsification of a record relating to a flight check, inadequate and inaccurate records regarding certain aircraft, and use of inaccurate weight information regarding baggage and passengers, he said.

The company, which also does business as Capitol Airlines, was authorized to operate as a commuter air carrier or an on-demand air taxi, with its airplanes to carry a maximum of 19 passengers.

Capitol has 10 days to appeal the order to the National Transportation Safety Board in Washington, said Swank.

Gary Cromer, general manager of Capitol, predicted the action by the FAA would keep the airline grounded for about a month ''if we're lucky.''

''The violations were nothing which would have endangered any passengers,'' he said. ''It's just a difference in record keeping.''

Cromer said that many of the violations were minor, such as pilots forgetting to document their flying times or signing off flight logs for one another.

The airline had regularly scheduled flights to Lawrence, Topeka, Manhattan and Salina, as well as Kansas City, Mo.
