What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Upon arrival at the accident site of 1181 west state road 39, Mooresville, IN, the aircraft was destroyed by fire. The instructor/pilot was giving dual instruction to the experimental helicopter builder and it was in phase I certification. The instructor/pilot smelled something hot and both occupants looked back at the engine compartment and saw black smoke. The helicopter was landed and then caught on fire. Containment of the fire was tried with the onboard fire extinguisher, two larger extinguishers, and a low water flow garden hose. After review of the information, the best case scenario is a fuel leak within the engine compartment causing a fire.
