Pratt & Whitney discloses fraudulent engine tests

EAST HARTFORD, Conn. (AP) Jet engine manufacturer Pratt & Whitney says it's uncovered fraudulent testing of engine parts, but that no recalls or other problems resulted.

The subsidiary of United Technologies Corp. said Monday that an investigation was initiated in June 2011 when an employee anonymously alleged that test data had been altered over 15 years at Carmel Forge, another United Technologies unit, in Israel.

The Wall Street Journal first reported the disclosure.

Pratt & Whitney confirmed that an internal investigation found employees doctored metallurgical test results to make certain engine forgings appear to meet strict standards when in fact they did not.

Pratt & Whitney says Carmel Forge has made personnel changes, established stronger software controls, purchased test equipment and taken other steps to prevent adjustments to original test data.
