ON APRIL 26, 2018 AT APPROXIMATELY 5:15 P.M. (EASTERN TIME), AIRCRAFT N87266 WAS INVOLVED IN AN ACCIDENT AT TANNER-HILLER AIRPORT (8B5) LOCATED IN NEW BRAINTREE, MA. ^PRIVACY DATA OMITTED^ PILOT ^PRIVACY DATA OMITTED^ WAS ACTING AS PILOT IN COMMAND (PIC). THE AIRCRAFT TOOK-OFF WITH FOUR ON BOARD BUT ONLY LANDED WITH THREE ON BOARD DUE TO A PLANNED PARACHUTE JUMP. THE AIRCRAFT ATTEMPTED TO LAND ON RUNWAY 6 BUT ENDED-UP GOING OFF THE FAR END OF THE RUNWAY ONTO A DIRT ROAD UNTIL IT IMPACTED A TREE. DISTANCE FROM EDGE OF RUNWAY ASPHALT TO THE AIRCRAFT?S FINAL RESTING POINT WAS ABOUT 300 FEET. AFTER IT IMPACTED SEVERAL TREES, THE AIRCRAFT CAME TO A STOP AND A FIRE STARTED ON THE LEFT WING, NUMBER 1 ENGINE, AND PARTS OF THE AIRCRAFT THAT HAD SEPARATED ON IMPACT. ALL ON-BOARD WERE ABLE TO ESCAPE THE AIRCRAFT WITH NO ASSISTANCE AND HAD NO INJURIES.

THE INSPECTOR IN CHARGE (IIC) IMMEDIATELY STARTED PHOTOGRAPHING THE SCENE WHEN HE ARRIVED AT THE SCENE. THERE WERE TWO SEGMENTED SKID MARKS DIRECTLY AFTER THE RUNWAY END LINE THAT WERE CREATED FROM THE RIGHT MAIN TIRE. THERE WERE TWO FAIRLY STRAIGHT MAIN TIRE INDICATIONS ONCE THE AIRCRAFT WAS IN THE DIRT. IT APPEARED THAT THE BRAKES WERE WORKING APPROPRIATELY. THE PIC CONFIRMED PROPER BRAKE OPERATION. THE MAIN TIRE MARKS STARTED TO DRIFT LEFT UNTIL THE LEFT WING IMPACTED THE FIRST TREE. IIC VERIFIED FLIGHT CONTROL FUNCTION FOR ALL CHANNELS EXCEPT THE RUDDER. THE RUDDER HAD TREE BRANCHES STUCK INSIDE THE HINGE AREA. FLAP SELECTOR WAS SET FULL DOWN AT 45DEGREES AND WAS ONLY VERIFIABLE ON RIGHT WING DUE TO LEFT WING DAMAGE.

THE IIC WAS ABLE TO FIND ALL MAJOR PART OF THE AIRCRAFT. SUBSTANTIAL DAMAGE WAS DETERMINED DUE TO THE FOLLOWING ISSUES: LEFT WING SEPARATED ABOUT 2 1/2 FEET OUTBOARD OF NUMBER 1 ENGINE CAUSING SIGNIFICANT STRUCTURAL DAMAGE AND FIRE DAMAGE, STRUCTURAL DAMAGE TO RIGHT LOWER SIDE OF THE EMPENNAGE, STRUCTURAL DAMAGE TO HORIZONTAL STABILIZER ON THE LEADING EDGE AND ELEVATOR ATTACHMENT POINT. WE ARE UNABLE TO SEE THE EXTENT OF DAMAGE TO THE UNDERSIDE OF THE AIRCRAFT DUE TO THE CURRENT RESTING POSITION OF THE AIRCRAFT AFTER THE LEFT MAIN LANDING GEAR SEPARATION.

ACCORDING TO BOTH THE PIC AND THE JUMPER, THE JUMPER JUMPED OUT EARLY DUE TO MISCOMMUNICATION. THIS AND THE WIND GUSTS CAUSED THE JUMPER TO BE OFF COURSE OF THE TARGET LANDING AREA. THE PIC BELIEVED THAT THE WIND DATA IN THE WEATHER REPORTS WERE INCORRECT. THE WEATHER DATA SHOWED THAT THE AIRCRAFT WOULD HAVE LANDED WITH A QUARTERING TAIL WIND. THE PIC STATED IN PART THAT HE MADE TWO GO-AROUNDS DUE TO THE ?AIR BEING BUMPY? AND HE "DID NOT LIKE IT". ON THE PIC?S THIRD ATTEMPT, HE STATED ?HE HAD A TAILWIND AND THE AIRCRAFT WOULD NOT SETTLE.? UPON TOUCHDOWN, ^PRIVACY DATA OMITTED^ APPLIED THE BRAKES BUT DUE TO THE POSITION OF THE AIRCRAFT, IT DEPARTED THE RUNWAY. THE PIC STATED THE BRAKES WERE FULLY FUNCTIONAL. THE AIRCRAFT HIT THE FIRST TREE BETWEEN THE LEFT TIP TANK AND THE NUMBER ONE ENGINE. THE AIRCRAFT HIT SEVERAL OTHER TREES AND SUSTAINED SUBSTANTIAL DAMAGE. THE AIRCRAFT AND SOME PIECES CAUGHT FIRE. THE PIC AND ALL PASSENGERS REMAINING ONBOARD EVACUATED THE AIRCRAFT ON THEIR OWN WITH NO INJURIES.
