WASHINGTON, July 30 (Reuters) - The chair of the Senate

Commerce Committee wants the Federal Aviation Administration to

conduct a thorough review into its oversight of Boeing ( BA )

and other manufacturers, raising serious questions about the

government's scrutiny of the planemaker.

Senator Maria Cantwell in a letter seen by Reuters to FAA

Administrator Mike Whitaker said the FAA in April disclosed that

it had conducted a combined total of 298 audits of Boeing ( BA ) and

Spirit AeroSystems ( SPR ) over the prior two years that "did

not result in any enforcement actions."
