WASHINGTON, Sept 12 (Reuters) - The head of the Federal

Aviation Administration will testify on Sept. 25 before the

Senate Permanent Subcommittee on Investigations on the

planemaker's oversight of Boeing ( BA ), a committee aide told

Reuters.

The committee, led by Senator Richard Blumenthal, in June

sharply questioned then Boeing ( BA ) CEO Dave Calhoun on the

planemaker's safety record. The hearing later this month titled

"FAA Oversight of Boeing's ( BA ) Broken Safety Culture" comes as

Whitaker has ramped up scrutiny of the planemaker since a Jan. 5

mid-air emergency in a new Alaska Airlines Boeing 737 MAX and

acknowledged it should have done more before the incident.
