May 28 (Reuters) - A weeks' long strike by 3,000 U.S.

Pratt & Whitney engine workers will impact free cash flow during

the second quarter, but the aerospace and defense giant should

be able to recover that during the year, RTX CEO Chris

Calio said on Wednesday.

"There will be cash impact here in the second quarter,"

Calio told the Bernstein Strategic Decisions Conference.

Calio said the four-week stoppage at Pratt's unionized

Connecticut factories impacted its ability to ship jet engines,

and he expects break even to negative cash flow in the quarter.

RTX shares dipped 2% in morning trade.
