From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Aircraft was pointed west on helipad, and upon lift-off, the pilot states that he "began a slow climb and left pedal turn in order to point the aircraft toward the southeast." As he vertically cleared a tree that was directly east of the pad (approx. 100 feet AGL), he began "a slow transition to forward flight" at which time he "immediately heard a loud bang," followed by "several alarms," and an instrument panel which he "noticed that everything was red." As the pilot pulled back on the collective in an attempt to reduce the rate of descent, the aircraft impacted the helipad, destroying the aircraft and causing serious injuries to the pilot, flight nurse and paramedic. Initial on site investigation revealed no anomalies with the airframe or engine. Subsequent inspection and test cell run of the engine was satisfactory. Aircraft vemd memory showed that the flight lasted about three minutes, and before engine shut down, there were no failures or overlimits. Flight nurse and paramedic stated that they did not recall hearing a "bang" during the chain of events leading to the accident. At this time, the cause of the accident is unknown.

As the FAA filed it

AIRCRAFT WAS POINTED WEST ON HELIPAD, AND UPON LIFT-OFF, THE PILOT STATES THAT HE "BEGAN A SLOW CLIMB AND LEFT PEDAL TURN IN ORDER TO POINT THE AIRCRAFT TOWARD THE SOUTHEAST." AS HE VERTICALLY CLEARED A TREE THAT WAS DIRECTLY EAST OF THE PAD (APPROX. 100 FEET AGL), HE BEGAN "A SLOW TRANSITION TO FORWARD FLIGHT" AT WHICH TIME HE "IMMEDIATELY HEARD A LOUD BANG," FOLLOWED BY "SEVERAL ALARMS," AND AN INSTRUMENT PANEL WHICH HE "NOTICED THAT EVERYTHING WAS RED." AS THE PILOT PULLED BACK ON THE COLLECTIVE IN AN ATTEMPT TO REDUCE THE RATE OF DESCENT, THE AIRCRAFT IMPACTED THE HELIPAD, DESTROYING THE AIRCRAFT AND CAUSING SERIOUS INJURIES TO THE PILOT, FLIGHT NURSE AND PARAMEDIC. INITIAL ON SITE INVESTIGATION REVEALED NO ANOMALIES WITH THE AIRFRAME OR ENGINE. SUBSEQUENT INSPECTION AND TEST CELL RUN OF THE ENGINE WAS SATISFACTORY. AIRCRAFT VEMD MEMORY SHOWED THAT THE FLIGHT LASTED ABOUT THREE MINUTES, AND BEFORE ENGINE SHUT DOWN, THERE WERE NO FAILURES OR OVERLIMITS. FLIGHT NURSE AND PARAMEDIC STATED THAT THEY DID NOT RECALL HEARING A "BANG" DURING THE CHAIN OF EVENTS LEADING TO THE ACCIDENT. AT THIS TIME, THE CAUSE OF THE ACCIDENT IS UNKNOWN.
