WASHINGTON, May 30 (Reuters) -

Boeing's ( BA ) outgoing CEO Dave Calhoun and other senior

company officials will detail the planemaker's quality, training

and other improvements during meetings with U.S. aviation

regulators on Thursday, according to sources with knowledge of

the matter.

In late February, Federal Aviation Administration chief Mike

Whitaker gave Boeing ( BA ) 90 days to develop a comprehensive plan to

address "systemic quality-control issues" and barred the

planemaker from expanding 737 MAX production after a door panel

blowout during a Jan. 5 flight on a new Alaska Airlines

737 MAX 9.

Whitaker will hear firsthand from Boeing ( BA ) executives on

quality efforts during a scheduled three-hour meeting at FAA

headquarters in Washington that could go longer, according to

the sources.

It will be Calhoun's second high-profile meeting with

Whitaker this year as Boeing ( BA ) seeks to have costly production

limits lifted by the FAA after soaring quality concerns

compelled the regulator to slow its rapidly increasing 737

production schedule.

Boeing ( BA ) confirmed a meeting would take place on Thursday, but

declined to provide further details. The FAA said Whitaker would

take part in a meeting with Boeing ( BA ).

Calhoun is due to exit the company by the end of the

year as part of a broader management shake-up announced in the

wake of the Alaska Airlines incident, but Boeing ( BA ) has not yet

named a replacement.

The meeting is set to include other senior Boeing ( BA )

leaders including Stephanie Pope, the new head of Boeing

Commercial Airplanes as well as Boeing's ( BA ) head of quality

Elizabeth Lund and Mike Fleming, Boeing ( BA ) senior vice president

and general manager, airplane programs, the sources said.

Boeing ( BA ) said this month it has added new training

material for manufacturing and quality roles averaging about 20

to 50 more training hours per employee, while more than 7,000

new tools and equipment have been provided for commercial

airplane work.

"We anticipate the FAA will take whatever time is necessary

to review that plan and hold us accountable," Calhoun said at

Boeing's ( BA ) annual meeting on May 17. "This is more of a beginning

than it is an end."

Whitaker, who plans to hold a press conference after the

meeting, said last week that Boeing ( BA ) faces a "long road" to

address safety issues. He added the 90-day plan "is not the end

of the process. It's the beginning and it's going to be a long

road to get Boeing ( BA ) back to where they need to be making safe

airplanes."

Boeing ( BA ) is currently producing significantly fewer than the

38 737 MAXs per month it is permitted under the FAA directive.

A February meeting between Boeing ( BA ) executives and

Whitaker lasted about seven hours.

Boeing ( BA ) faces a separate criminal investigation into the

MAX 9 mid-air emergency. The Justice Department said this month

that Boeing ( BA ) breached its obligations in a 2021 agreement

shielding the planemaker from criminal prosecution over fatal

737 MAX crashes.

Boeing ( BA ) denied it has breached the deal. The Justice

Department directed Boeing ( BA ) to respond by June 13 and intends to

decide whether to prosecute Boeing ( BA ) by July 7.
