WASHINGTON — The Federal Aviation Administration proposed a $435,000 fine Tuesday for United Airlines for allegedly flying a Boeing 787 without inspecting its fuel pump.

The airline wants to continue discussing with case with regulators.

United mechanics replaced the pressure switch on the Dreamliner’s fuel pump on June 9, 2014, after the crew documented a problem two days earlier, according to the FAA.

But the airline allegedly failed to perform a required inspection before returning the plane to service. The plane flew 23 times before the inspection occurred on June 28, 2014, according to FAA. Regulators contend the plane wasn’t airworthy during those flights.

“Maintaining the highest levels of safety depends on operators closely following all applicable rules and regulations,” FAA Administrator Michael Huerta said in a statement. “Failing to do so can create unsafe conditions.”

United has asked to meet with FAA officials to discuss the case.

“At United, the safety of our customers and employees is our top priority,” spokesman Charles Hobart said. “We immediately took action after identifying the issue and are working closely with the FAA in their review.”
