## Analysis

ON JUNE 22, 1985 THE PLT AND THREE PASSENGERS BOARDED N98079. AFTER TAXING TO RWY 27 (WHICH HAS A ONE DEGREE UPGRADE), THE ACFT BEGAN AN EXTENDED GROUND ROLL WITH A LEFT-QUARTERING TAILWIND OF APPROXIMATELY EIGHT KNOTS. AT THIS TIME, THE ACFT WAS LOADED ABOUT 49 POUNDS FROM GROSS WEIGHT AND THE ENGINE HAD ACCUMULATED 1529 HOURS SINCE MAJOR OVERHAUL. FOLLOWING ROTATION, THE ACFT MAINTAINED A NOSE HIGH ATTITUDE AND INITIATED A LEFT BANK. THE ACFT THEN CLIMBED ANOUT 200 FEET, BEFORE THE NOSE AND LEFT WING RAISED ABRUPTLY AND THE RIGHT WING LOWERED. THE ACFT THEN DISAPPEARED BELOW THE TREES NEAR THE END OF THE RWY 27. THE ACFT CAME TO REST IN THE BACKYARD OF A RESIDENCE AT 5022 EAST JOPPA ROAD, PERRY HALL, MD. EXAMINATION OF THE ENGINE DID NOT REVEAL ANY DISCREPANCIES, ALTHOUGH THE SPARK PLUGS APPEARED WORN. AT THE TIME OF THE ACCIDENT, ABOUT 1917 FEET OF RWY WAS REQUIRED TO CLEAR A 50 FOOT OBSTACLE, USING A DENSITY ALTITUDE OF 1500 FEET. RWY 27 IS 2200 FEET IN LENGTH, WITH TREES ABOUT 50 FEET IN HEIGHT AT THE DEPARTURE END.
