- Loss of control - in flight, climb - to cruise
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - aircraft weight and balance - exceeded, pilot in command (cause)
  - compensation for wind conditions - inadequate, pilot in command (contributing factor)
  - weather condition - tailwind (contributing factor)
  - in-flight planning/decision - poor, pilot in command (cause)
  - rotor rpm - not maintained, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing - flare/touchdown
  - object - vehicle (contributing factor)

## Analysis

THE PLT OF A BELL 206L MADE A DOWNWIND TKOF WITH THE ACFT LOADED MORE THAN 100 LBS OVER THE MAXIMUM ALLOWABLE GROSS TKOF WEIGHT. AT AN ALTITUDE OF APPROX 100 FT, WHILE COMPLYING WITH NOISE ABATEMENT TKOF PROCEDURES, THE PLT EXPERIENCED DECREASING MAIN ROTOR RPM AND A LOW ROTOR RPM WARNING HORN. HE ATTEMPTED TO RETURN TO THE LNDG PAD, HOWEVER, LNDD 200 FT SHORT. THE HELICOPTER CAME TO REST ON ITS LEFT SIDE AFTER STRIKING A PARKED CAR.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
