WASHINGTON (AP) _ The Federal Aviation Administration is proposing fining Gemini Air Cargo Inc. $75,000 for failing to perform proper maintenance on a DC-10 jetliner, the agency announced Friday.

Gemini, based at Dulles International Airport outside of Washington, violated FAA maintenance regulations, the agency charged.

The FAA alleged that the company did not perform maintenance needed to return a Douglas DC 10-30F to its original or to a proper condition, installed unapproved parts and misdrilled holes while installing the wing hinge assembly.

As a result, the FAA said, Gemini Air Cargo operated the DC-10 in a condition not airworthy for more than 90 flights between April 20 and June 9, 1998.

Gemini has 30 days from receipt of the FAA notice to submit a reply.
