(Reuters) - A federal watchdog on Friday criticized the Federal Aviation Administration's oversight of Boeing ( BA ) airplane production, saying it does not have an effective system to oversee the planemaker's individual manufacturing facilities.

The Transportation Department's Office of Inspector General said in a report the FAA's current audit processes "are not comprehensive enough to adequately identify key discrepancies and noncompliances within the Boeing ( BA ) production line" and said the FAA has not addressed longstanding weaknesses in Boeing's ( BA ) oversight of suppliers despite long-known risks.
