A whistleblower has urged Boeing to ground every 787 Dreamliner jet worldwide after warning they are at risk of premature failure ahead of a high-profile hearing on Capitol Hill.

The planemaker has been grappling with its latest crisis since a cabin panel blowout in January raised fresh questions about the production of its bestselling commercial jet, the 737 Max.

Asked if Boeing should ground 787 jets for inspection, he told NBC News: “The entire fleet worldwide, as far as I’m concerned right now, needs attention.

At a briefing on Monday, executives described how a rigorous program of tests and inspections had left the firm confident of the jets’ durability.

After scrambling to reassure regulators, airlines and passengers in the wake of January’s blowout, Dave Calhoun, Boeing’s chief executive, and Larry Kellner, chairman of its board, announced plans to resign last month.
