CHICAGO, July 17 (Reuters) - GE Aerospace CEO

Larry Culp said on Thursday the company's efforts to fix supply

constraints are showing results and driving up jet engine

deliveries.

The comments came after the company reported a 45% jump in

total engine deliveries in the second quarter from a year ago.

Deliveries of LEAP engines, which power narrowbody jets of

Airbus and Boeing ( BA ), were up 38% from a year ago.

"We are chasing a moving target. But I think those numbers

... suggest we're making real progress," Culp told Reuters in an

interview.
