## Discrepancy

THE STARBOARD MUFFLER BAFFLE CONE BROKE LOOSE FROM THE MUFFLER HOUSING AND OBSTRUCTED THE EXHAUST PIPE, CREATING BACK PRESSURE IN THE EXHAUST SYSTEM WHICH CAUSED THE ENGINE TO LOSE POWER. THE SUBSEQUENT FORCED LANDING ACCIDENT SUBSTANTUALLY DAMAGED THE AIRCRAFT AND AN AUTOMOBILE ON THE GROUND. THE FIVE PEOPLE IN THE AIRCRAFT AND IN THE CAR RECEIVED ONLY MINOR INJURIES.
