Riverside Plant of Rohr Under Investigation : Defense: The government contractor says the federal probe involves parts production, records and testing.

Rohr Inc. said Tuesday that there is an ongoing federal investigation into “various acts of employees” at the company’s Riverside manufacturing plant that might result in criminal and civil charges.

In a prepared release, Rohr said the probe focuses on the “production of parts, the recording of information which is a part of the product process and the company’s testing practices.”

Rohr said it has done nothing that would have “an adverse effect on the safety or utilization of its products.”

The outcome of the investigation could affect Chula Vista-based Rohr’s ability to retain current government contracts, and jeopardize future ones. Rohr also could face “substantial” fines and civil damage judgments.

Carol Levitsky, a spokeswoman for the U.S. attorney’s office in Los Angeles, confirmed that an investigation is underway. She declined to discuss the substance of the probe, which is being conducted with the Defense Department.

Vice President Ron Miller said Rohr does not know how many employees or which military programs are being investigated. “All we know is that it’s an ongoing investigation,” he said.

Rohr’s 3,500 employees in Riverside produce engine components for a number of commercial and military aircraft, including the F-14 fighter, the C-5 transport and the KC-135 tanker.

Government contracts account for about 15% of Rohr’s $1.3 billion in annual revenue. The company acts largely as a subcontractor to prime contractors who build various military and commercial aircraft.

In another announcement Tuesday, Rohr said the Air Force is considering termination of a contract to provide 206 engine pylons for the C-5 military transport. The Air Force has ordered Rohr to “explain why the delayed delivery of four C-5 (engine) pylons should not be grounds for termination” of the pylon contract.

The company said “it has satisfactory reasons” for the late delivery of pylons, although it did not elaborate. The company said it already has delivered pylons valued at $38.6 million.
