What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot departed rwy 24 at kjxn for a pleasure flight to coldwater. Shortly after takeoff, pilot detected engine roughness. Returned to kjxn for a landing. Pilot speculated fouled plugs or carb icing. Pilot conducted engine run-up and determined issue corrected. Pilot then departed rwy 24 to remain in the pattern for practice. Shortly after turning crosswind to downwind, at about 1000' AGL, engine ran extremely rough. Pilot applied carburetor heat which caused the engine to run rougher so he immediately turned carburetor heat off. Pilot contacted tower to land immediately. Pilot cleared for rwy 32. However, aircraft was high, fast, and about 1/4 mile off the approach end of rwy 32. Aircraft landed more than halfway down rwy 32. Aircraft hit hard; bounced; then aircraft began to porpoise. On 4th bounce, aircraft hit nose hard and nose gear collapsed. Upon inspection by maintenance personnel, it appeared that the firewall was undamaged although engine mounts were deformed, propeller tips bent, and nosegear pushed up into lower cowling. Ntsb's todd fox and GL-23 a/w front line manager consulted. Conclusion is that this event is an "incident."
As the FAA filed it

PILOT CONDUCTED ENGINE RUN-UP AND DETERMINED ISSUE CORRECTED. PILOT THEN DEPARTED RWY 24 TO REMAIN IN THE PATTERN FOR PRACTICE. SHORTLY AFTER TURNING CROSSWIND TO DOWNWIND, AT ABOUT 1000' AGL, ENGINE RAN EXTREMELY ROUGH. PILOT APPLIED CARBURETOR HEAT WHICH CAUSED THE ENGINE TO RUN ROUGHER SO HE IMMEDIATELY TURNED CARBURETOR HEAT OFF.PILOT CONTACTED TOWER TO LAND IMMEDIATELY. PILOT CLEARED FOR RWY 32. HOWEVER, AIRCRAFT WAS HIGH, FAST, AND ABOUT 1/4 MILE OFF THE APPROACH END OF RWY 32. AIRCRAFT LANDED MORE THAN HALFWAY DOWN RWY 32. AIRCRAFT HIT HARD; BOUNCED; THEN AIRCRAFT BEGAN TO PORPOISE. ON 4TH BOUNCE, AIRCRAFT HIT NOSE HARD AND NOSE GEAR COLLAPSED. UPON INSPECTION BY MAINTENANCE PERSONNEL, IT APPEARED THAT THE FIREWALL WAS UNDAMAGED ALTHOUGH ENGINE MOUNTS WERE DEFORMED, PROPELLER TIPS BENT, AND NOSEGEAR PUSHED UP INTO LOWER COWLING. NTSB'S TODD FOX AND GL-23 A/W FRONT LINE MANAGER CONSULTED. CONCLUSION IS THAT THIS EVENT IS AN "INCIDENT."
