The FAA is recommending record checks for potential improper bearing work conducted by AeroBearings in Arlington, Texas. The agency recently issued a Safety Alert for Operators (SAFO) advising that an investigation of the Kornitzky Group, which does business as AeroBearings, revealed that the company conducted work without the necessary approved data.
“As a result, AeroBearings LCC could not determine whether the bearings met the original equipment manufacturer’s (OEM) design specifications,” the agency said, adding it revoked the AeroBearings certificate in March. AeroBearings was not available for comment at press time.
AeroBearings’ certificate covered aeronautical anti-friction bearings used in turbine engines, auxiliary power units (APU), rotorcraft drive systems, and accessory applications. The FAA has the company’s capability list online, which includes Pratt & Whitney Canada PT6 and Honeywell TPE331 turboprop engines.
In the SAFO, the agency advises that aircraft owners, operators, suppliers, air agencies, distributors, and maintenance technicians inspect records and inventory for any bearings approved for return to service by AeroBearings. “Any bearing found to be overhauled, repaired, or inspected by AeroBearings LLC that is not installed should be quarantined until the suspect bearing undergoes a recertification inspection to determine airworthiness prior to installation,” the agency said. Bearings already installed should be inspected “at the next piece parts exposure” and owners/operators are advised to closely monitor those bearings, the FAA further said.
