What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot stated than after entering the aircraft and buckling in, he closed the aircraft door. He did not feel that the door closed properly, so he repeated the door closing process, using additional force to ensure it was properly closed. Pilot stated that he rotated approximately halfway down runway 22, and that just after rotation and at the start of his climb, he heard a loud "bang". Pilot estimates that he was 20 feet off of the runway when he heard the noise. Pilot states that he that he immediately looked to his right and confirmed his suspicion that the noise was caused by the door being open. He stated that the door was fully open and appeared to be in the latched open position because it was not closer to the fuselage as he expected it would be. Pilot stated that ?bonanza doors are known to pop open and I had experienced this phenomenon on two other occasions. On both of those occasions, the door never opened more than about six inches and the plane flew fine, allowing me to land and re-close the door without incident. This time it stayed open and latched. At the same lime, the plane started "fish tailing". I had never experienced that phenomenon before. Thus, I concluded that the open door was the reason and being totally uncertain as to the flying characteristics of the aircraft with the door latched wide open, I looked down the runway to see how much runway remained. Believing that I could put the plane back on the runway and stop the plane before the end of the runway, and having no idea whether I could control the plane if I continued the take-off, I decided to land the plane and make every effort to stop it before reaching the end of rwy 22. Unfortunately, I could not stop the plane in time?. The pilot was unable to stop the aircraft, rolled off the end of the runway, and impacted the airport perimeter fence which kept the aircraft from crossing onto a road. Pilot estimates that aircraft speed at impact with fence to be less than 20 knots. Pilot was unhurt, and exited the aircraft through the still open door.
As the FAA filed it
PILOT STATED THAN AFTER ENTERING THE AIRCRAFT AND BUCKLING IN, HE CLOSED THE AIRCRAFT DOOR. HE DID NOT FEEL THAT THE DOOR CLOSED PROPERLY, SO HE REPEATED THE DOOR CLOSING PROCESS, USING ADDITIONAL FORCE TO ENSURE IT WAS PROPERLY CLOSED. PILOT STATED THAT HE ROTATED APPROXIMATELY HALFWAY DOWN RUNWAY 22, AND THAT JUST AFTER ROTATION AND AT THE START OF HIS CLIMB, HE HEARD A LOUD "BANG". PILOT ESTIMATES THAT HE WAS 20 FEET OFF OF THE RUNWAY WHEN HE HEARD THE NOISE. PILOT STATES THAT HE THAT HE IMMEDIATELY LOOKED TO HIS RIGHT AND CONFIRMED HIS SUSPICION THAT THE NOISE WAS CAUSED BY THE DOOR BEING OPEN. HE STATED THAT THE DOOR WAS FULLY OPEN AND APPEARED TO BE IN THE LATCHED OPEN POSITION BECAUSE IT WAS NOT CLOSER TO THE FUSELAGE AS HE EXPECTED IT WOULD BE. PILOT STATED THAT ?BONANZA DOORS ARE KNOWN TO POP OPEN AND I HAD EXPERIENCED THIS PHENOMENON ON TWO OTHER OCCASIONS. ON BOTH OF THOSE OCCASIONS, THE DOOR NEVER OPENED MORE THAN ABOUT SIX INCHES AND THE PLANE FLEW FINE, ALLOWING ME TO LAND AND RE-CLOSE THE DOOR WITHOUT INCIDENT. THIS TIME IT STAYED OPEN AND LATCHED. AT THE SAME LIME, THE PLANE STARTED "FISH TAILING". I HAD NEVER EXPERIENCED THAT PHENOMENON BEFORE. THUS, I CONCLUDED THAT THE OPEN DOOR WAS THE REASON AND BEING TOTALLY UNCERTAIN AS TO THE FLYING CHARACTERISTICS OF THE AIRCRAFT WITH THE DOOR LATCHED WIDE OPEN, I LOOKED DOWN THE RUNWAY TO SEE HOW MUCH RUNWAY REMAINED. BELIEVING THAT I COULD PUT THE PLANE BACK ON THE RUNWAY AND STOP THE PLANE BEFORE THE END OF THE RUNWAY, AND HAVING NO IDEA WHETHER I COULD CONTROL THE PLANE IF I CONTINUED THE TAKE-OFF, I DECIDED TO LAND THE PLANE AND MAKE EVERY EFFORT TO STOP IT BEFORE REACHING THE END OF RWY 22. UNFORTUNATELY, I COULD NOT STOP THE PLANE IN TIME?. THE PILOT WAS UNABLE TO STOP THE AIRCRAFT, ROLLED OFF THE END OF THE RUNWAY, AND IMPACTED THE AIRPORT PERIMETER FENCE WHICH KEPT THE AIRCRAFT FROM CROSSING ONTO A ROAD. PILOT ESTIMATES THAT AIRCRAFT SPEED AT IMPACT WITH FENCE TO BE LESS THAN 20 KNOTS. PILOT WAS UNHURT, AND EXITED THE AIRCRAFT THROUGH THE STILL OPEN DOOR.
