THE AIRCREW WERE ON AN INSTRUCTIONAL FLIGHT TO PREPARE THE STUDENT, A RATED PILOT, FOR A FLIGHT INSTRUCTOR RATING. AFTER PRACTICING SEVERAL AUTOROTATION APPROACHES, THE HELICOPTER WAS LANDED. THE INSTRUCTOR PILOT (IP) STATED THAT AFTER TOUCHDOWN, HE AND THE STUDENT WERE IN A DISCUSSION WHEN THEY HEARD A LOUD "POP". THE IP DEPLANED AND INSPECTED THE HELICOPTER, BUT FOUND NO IRREGULARITIES. THEY TOOK OFF AND PERFORMED ANOTHER AUTOROTATION. AFTER TOUCHDOWN, THE COLLECTIVE WAS LOWERED, THE HELICOPTER PITCHED LEFT AND FORWARD, AND THE ROTOR BLADES CONTACTED THE GROUND AND TAIL BOOM.

ACCORDING TO A METALLURIGICAL REPORT, A SINGLE OVERLOAD FRACTURE WAS FOUND AT THE CLEVIS ON THE PISTON END OF THE DAMPER. THE CFI DID NOT REPORT ANY HARD LANDINGS.
