DALLAS—A former senior Boeing test pilot told a co-worker that he unknowingly misled safety regulators about problems with a flight-control system that would later be implicated in two deadly crashes of the company’s 737 Max.
The pilot, Mark Forkner, told another Boeing employee in 2016 that the flight system, called MCAS, was “egregious” and “running rampant” while he tested it in a flight simulator.
