Regulators are directing US operators of Boeing Co 777 widebody jets to repair aircraft to address concerns about potential fuel-tank explosions, according to a filing.
A proposed airworthiness directive from the US Federal Aviation Administration (FAA) calls for operators to inspect the jets and install Teflon sleeves and cap fasteners to certain parts of the centre, left and right main fuel tanks. The order would apply to 282 jets, the FAA said.
The FAA estimates it will take about 90 hours per plane to conduct the inspections and repairs at a total cost of $14 million for US fleet of the 777 jets.
