The agreement was reached at a top-level meeting between the airline and Department of Transport officials.

Earlier this week, it was alleged that a Far Eastern Boeing 747 arrived at London's Heathrow Airport with two empty fuel tanks.

In a report, ground handling agents said it was not the first time that the unnamed carrier had allegedly landed with low fuel levels, contravening international aviation rules.

Malaysia, which denied that its aircraft had broken any fuel regulations, promised to present its records to officials.

Weekly checks

It has now agreed that weekly checks should become part of its operating terms, the Department of Transport said.

Aviation minister Glenda Jackson said: "Malaysia Airlines has co-operated fully in reviewing their fuel policy and examining why, on very few occasions, low fuel levels have been recorded at the completion of a flight.

"Their offer to provide us with weekly reports of fuel levels for all their aircraft arriving in the UK has been incorporated in their conditions for operating into the country."

Extra inspections

Ms Jackson also announced that the Civil Aviation Authority would be carrying out extra inspections of foreign aircraft arriving in Britain after long-haul flights.

The Far Eastern jumbo was reported to have landed at Heathrow with 3.34 tonnes of fuel on board. Aviation experts said this would have been insufficient if the plane had been forced to divert to another airport or suffered delays.

But Malaysia insisted that it was obeying Malaysian, British and American rules, saying that the average amount of fuel on its jets arriving in London from Kuala Lumpur in the past six months had been 9.7 tonnes.
