In a letter to Boeing chief executive Dennis Muilenburg on Friday,FAA Administrator Stephen Dickson said:"I expect your explanation immediately."
The FAA said in a statement that it"finds the substance of the document concerning. The FAA is also disappointed that Boeing did not bring this document to our attention immediately upon its discovery."
The flurry of messages between the pilots came over a 10-minute stretch in 2016 as the company was working with the FAA to obtain the safety certification needed to sell the Max in the United States and around the world. The new plane was critical to Boeing's plans to compete with rival Airbus. The FAA granted Boeing the coveted certification in March 2017.
A copy of the message chain was given to the Justice Department in February in connection with the criminal probe into the Max,according to Richard Cullen,an attorney at McGuire Woods representing Boeing.
Cullen said the document was produced properly and in a timely fashion"to the appropriate agency."
A separate set of emails from Forkner to FAA officials,in which the Boeing executive often assumed a familiar or chummy tone,showed an active company effort to remove references to the MCAS from the Flight Crew Operating Manual.
"I noticed a few things that should be changed,"Forkner wrote to one FAA official in 2017."Delete MCAS,recall we decided we weren't going to cover it in the"Flight Crew Operating Manual since it is"way outside the normal operating envelope,"meaning what pilots would typically face.
A report released last week by a group of international and US aviation safety experts found the decision to remove the reference to the MCAS in that document meant the FAA board that considers requirements for preparing pilots"was not in a position to adequately assess training needs."
Investigators have noted that assumptions that pilots could immediately handle an MCAS problem proved deadly.
In a 2016 email,Forkner told an FAA official he was"doing a bunch of travelling through the next few months"and that he would be"jedi-mind tricking regulators into accepting the training that I got accepted by the FAA etc."
Boeing said Friday it"will continue to cooperate"with an investigation by the House Transportation Committee and"we will continue to follow the direction of the FAA and other global regulators,as we work to safely return the 737 Max to service."
In a call to Dickson on Friday,Muilenburg told the administrator that the company is"taking every step possible to safely return the Max"to the air,Boeing said.
Forkner moved to Southwest Airlines last year. Gustavsson was promoted to Boeing's 737 chief technical pilot in 2018,according to a LinkedIn listing. Boeing did not answer a question about Gustavsson's current role.
The existence of the instant messages was first reported by Reuters.
Representative Peter DeFazio,chairman of the Transportation Committee,said the message chain showed"Boeing withheld damning information from the FAA."
"This exchange is shocking,but disturbingly consistent with what we've seen so far in our ongoing investigation,"DeFazio said,pointing to"a lack of candor with regulators and customers."
"This is not about one employee;this is about a failure of a safety culture at Boeing in which undue pressure is placed on employees to meet deadlines and ensure profitability at the expense of safety,"DeFazio said.
In a letter to Transportation Secretary Elaine Chao on Friday,DeFazio said the"jedi-mind tricking"email and others showed"an improper coziness between the regulator and the regulated,"and added that it was"outrageous"and"unacceptable"that the FAA had not previously provided his committee with those and other requested emails months ago.
Forkner set the tone early in the 2016 messages,writing:"I'm locked in my hotel room with an ice cold grey goose,I'll probably fire off a few dozen inappropriate emails before I call it a night."
