Aug 12 (Reuters) - Spirit AeroSystems ( SPR ) CEO

Patrick Shanahan will receive a payout of $28.5 million after

the 737 MAX fuselage supplier completes its merger with Boeing ( BA )

, according to a regulatory filing on Monday.

Shanahan will get a cash payment of $2.3 million, converted

Spirit restricted stock units worth $26.1 million and

perquisites and benefits worth $45,000 as part of a package

known as a "golden parachute".

Such payments are commonplace in corporate America and are

intended to incentivize management to sell a company, even if it

means ending their own employment.

Boeing ( BA ) agreed in July to buy back Spirit AeroSystems ( SPR ) for

$4.7 billion in stock and Airbus moved to take on the

supplier's loss-making Europe-focused activities. It was a

transatlantic break-up of the world's largest standalone

aerostructures company.

Shanahan had been seen as a frontrunner to take over the

reins at Boeing ( BA ), which is now headed by former aerospace

executive Kelly Ortberg.

Boeing ( BA ) chair Steven Mollenkopf asked Shanahan in May if he

would be interested in being considered as a candidate for the

role of Boeing's ( BA ) president and chief executive officer, the

filing showed.

Shanahan responded that he would not rule out being in the

running for the role, according to the filing.
