Washington: Boeing's ousted chief executive officer, Dennis Muilenburg, is leaving the company with $US62 million ($90 million) in compensation and pension benefits but will receive no severance pay in the wake of the company's 737 Max crisis.

Muilenburg was fired from the job in December as Boeing failed to contain the fallout from two fatal crashes that halted output of the company's bestselling 737 Max jetliner and tarnished its reputation with airlines and regulators.

The compensation figures were disclosed in a regulatory filing late on Friday, US time, during a difficult week for Boeing when it also released hundreds of internal messages - two major issues hanging over the company before new CEO David Calhoun starts on Monday.

The messages contained harshly critical comments about the development of the 737 Max, including one that said the plane was "designed by clowns who in turn are supervised by monkeys."
