## Discrepancy

ON AUGUST, 2010, AT APPROX 20:00 PDT, RECEIVED A CALL FROM FLIGHT SCHOOL, INFORMING US THAT ACFT HAD MADE AN UNSCHEDULED LANDING FOLLOWING A PARTIAL POWER LOSS EVENT.  ACFT WAS REMOVED FROM SERVICE PENDING INVESTIGATION.  ON THE 9TH OF AUGUST, CONDUCTED AN INSP AND FOUND THAT THE MUFFLER INNER BAFFLE SEPARATED AND MAY HAVE PARTIALLY COVERED THE OUTLET FOR THE EXHAUST.
