Boeing has ordered inspections of its entire fleet of grounded 737 Max planes after it found debris in the fuel tanks of some of the aircraft, in the latest setback for the US plane-maker.

The specialist aviation blog Leeham News, which first reported the discovery of the “foreign object debris” (FOD), said it was unlikely that the inspections would delay the recertification of the jets. However, it will take up to three days to inspect each plane because fuel must be drained and vapours dissipated before the fuel tanks can be opened.

Mark Jenks, the general manager of the 737 programme, said in a memo to employees that the debris was “absolutely unacceptable” and that the company was taking steps to address the problem in its production system.
