THE BOISE FSDO WAS NOTIFIED OF AN AIRCRAFT THAT CRASHED DURING AN ABORTED TAKEOFF WHILE DEPARTING RUNWAY 9 AT JEROME, ID AIRPORT. THE PILOT?S EMAIL STATEMENT: ?AS PER OUR CONVERSATION THE OTHER DAY, CORSAIR N-965CV WENT TO ^PRIVACY DATA OMITTED^ AIR POWER UNLIMITED SHOP ON OCTOBER 2018 AND THE AIRCRAFT WAS SIGNED OFF ON IT'S ANNUAL THIS MAY 10TH 2019. THIS PAST MONDAY, I WENT TO INSPECT THE AIRCRAFT AND THE NEXT DAY PREPARED THE AIRCRAFT FOR DEPARTURE FOR AN AIR SHOW "TBM GATHERING" AT KVYS PERU ILLINOIS. AFTER AN DETAILED GROUND PRE-CHECK THE AIRCRAFT STARTED AS NORMAL, I TAXIED TO THE DEPARTURE END OF RUNWAY 9 USING THE AIRCRAFT'S CHECK LIST I FOUND ALL SYSTEM READY AND TEMPS IN THE GREEN. I HELD A FEW MINUTES WAITING FOR A CROP-DUSTER TO LAND. NEXT I ANNOUNCED N-965 CV WAS TAKING THE ACTIVE RW 9 AT JEROME AND HOLDING.. HOLDING ON THE RUNWAY I DID MY FINAL COCKPIT CHECK. I ANNOUNCED ME DEPARTURE AND STARTED MY TAKE OFF ROLL. THE CORSAIR ACCELERATED NOUNALLY. I PINNED THE TAIL UP AND JUST PRIOR TO ROTATION THERE WAS A SHUTTER / AND AUDITABLE NOISE FOLLOWED BY A VERY NOTICEABLE DECELERATION. I INSTINCTIVELY PULLED THE POWERS AND "VERY" AGGRESSIVELY ABORTED THE TAKE OFF.? THE PILOT FOLLOW-UP EMAIL STATEMENT: ?IT'S COME TO MY ATTENTION THAT THERE WAS A COMMENT ABOUT ELEVATOR TRIM BEINGS SET WRONG. THIS COMMENT WAS MADE BY MY MECHANIC ^PRIVACY DATA OMITTED^. I TOLD ^PRIVACY DATA OMITTED^ THAT I HAD NEGLECTED TO TURN OFF THE ELECTRICAL SYSTEM ON CORSAIR AFTER THE CRASH. I BELIEVE MORE THAN ONE PERSON HEARD ME SAY I FORGOT TO TURN OFF THE ELECTRICAL. I'M RELATIVELY SURE ^PRIVACY DATA OMITTED^ KNEW AND HEARD THE ELECTRICAL SYSTEM WAS STILL ON WHEN I REMOVED MYSELF FROM THE AIRCRAFT. WITH THE CHINAMAN'S CAB LOCATED ON THE VERY TOP OF THE STACK, I'M SURE I MOVED THE SETTINGS HITTING IT WITH MY HELMET AND OR USING THE STICK TO GET OUT. THERE WAS ONE ANOTHER COMMENT MADE BY ^PRIVACY DATA OMITTED^ THAT THE TAIL WAS HIGH IN THE AIR, YES I ALWAYS FLY THIS TYPE OF AIRPLANE: P 51 OR CORSAIR PINNED TO THE GROUND UNTIL I HAVE POSITIVE SPEED FOR A POSITIVE TAKEOFF. WITH THE ROCKETS ADDING ADDITIONAL DRAG, I WAS LOOKING FOR 95 PLUS KNOTS. THIS PERHAPS IS WHAT ^PRIVACY DATA OMITTED^ WAS LOOKING AT.? AN EYEWITNESS CAPTURED A VIDEO OF THE EVENT. THE VIDEO SHOWS A CORSAIR ON A DEPARTURE ROLL AND THEN AN ABORTED TAKEOFF. THE ABORTED TAKEOFF APPEARS TO OCCUR AFTER MIDFIELD AND APPROXIMATELY THREE-QUARTERS DOWN RUNWAY 9. THE AIRCRAFT THEN DEVIATED FROM GOING STRAIGHT DOWN THE RUNWAY TO DRIFTING OFF THE RUNWAY TO THE LEFT WITH THE AIRCRAFT PARTIALLY OPERATING IN THE DIRT. THE VIDEO FURTHER SHOWS THE AIRPLANE GOING OFF THE END OF THE RUNWAY, HITTING UNEVEN TERRAIN, THEN BECOMING AIRBORNE GAINING ABOUT 10 VERTICAL FEET, HITTING A CHAIN LINK FENCE AND COMING TO A REST UPRIGHT. THE FAA INSPECTION OF THE AIRCRAFT AFTER IT WAS RELOCATED BACK TO THE JEROME, ID AIRPORT REVEALED THE AIRCRAFT RECEIVED DAMAGE TO THE LEFT INBOARD WING THAT CONTINUED INTO THE WING SPAR. THE LANDING GEAR COLLAPSED AND WAS SUBSTANTIALLY DAMAGE. FURTHERMORE, THE PROP STRUCK THE GROUND AND WAS DAMAGED. ON 6/20/19 FAA AW AND OPS INSPECTOR'S OBSERVED TWO AIR POWER UNLIMITED MAINTENANCE TECHNICIANS CONDUCT AN ENGINE INSPECTION AT THE REQUEST OF NTSB. TWO SPARK PLUGS WERE NOT SPARKING. THE REST OF THE INSPECTION AT THE TIME DID NOT SHOW ANY DISCREPANCIES. THE CARBURETOR WAS REMOVED AND SHIPPED TO NTSB FOR FURTHER INSPECTION. THE FAA AW INSPECTOR STATED NO ITEMS WERE FOUND WHICH IN HIS OPINION COULD HAVE CONTRIBUTED TO THE TAKE OFF ACCIDENT. FURTHER REVIEW OF THE AFM THAT WAS LOCATED IN THE AIRPLANE SHOWS THE AIRMAN NEEDED APPROXIMATELY 1200 TO 1500 FEET OF RUNWAY FOR TAKEOFF WITH APPROXIMATELY 74 TO 80 KNOTS OF AIRSPEED TO ROTATE ACCORDING TO THE TAKE-OFF CHART. THE AFM STOPPING DISTANCE CHART SHOWS ABOUT 1500 FEET OF RUNWAY IS NEEDED AT ROTATE SPEED. THE AIRMAN WAS STILL ON TAKEOFF ROLL AT APPROXIMATELY 2500 FEET AND HE APPEARS TO BEING TRAVELING AT 100 TO 130 KNOTS. THE AIRMAN DID NOT ROTATE. ## The NTSB's investigation of this event (1) From the NTSB's public API.
