## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) ACCIDENT OCCURRED WHILE HELICOPTER AIR AMBULANCE CREW WAS ATTEMPTING TO MAKE A NIGHT LANDING INTO A LZ WHICH WAS SET UP ALONG A RESIDENTIAL STREET BY THE AMBULANCE GROUND CREW. THE APPROACH WAS ABORTED WHILE ON SHORT FINAL DUE TO UNFAVORABLE CONDITIONS WITHIN THE LZ. DURING THE GO-AROUND PROCEDURE, WIRES WERE OBSERVED BY THE PIC AT WHICH TIME A CLIMBING RIGHT TURN WAS INITIATED. ONCE THE WIRES WERE CLEARED, THE A/C SPUN TO THE RIGHT AT LEAST 180 DEGREES. THE PIC THEN LOWERED COLLECTIVE POWER IN ORDER TO LAND THE A/C WITHIN THE VACANT DIRT LOT LOCATED DIRECTLY UNDER HIM. DURING THE ATTEMPT TO LAND, THE A/C LANDED APPROX. 10 DEGREES RIGHT SKID LOW, AND APPROX. 10 DEGREES NOSE LOW. THIS ABRUPT LANDING ATTITUDE IN CONJUNCTION WITH A RIGID ROTOR SYSTEM CAUSED A ROLLING MOTION (DYNAMIC ROLLOVER) WHICH COULD NOT BE CORRECTED. THE A/C SUBSEQUENTLY CONTINUED IN A RIGHT ROLL EVENTUALLY RESTING ON ITS RIGHT SIDE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
