This award surprised me. At the time my understanding of the accident was that although it fitted the tail rotor problem scenario this accident occurred after Bell had issued directions for its solution [I cannot recall whether it was an SB or an AD at that stage]. The accident airframe had not been modified when it had a tail strike and landed hard. Both fatalities were caused by the passengers [panicking and?]leaving the aircraft and walking into the main rotor disc [which was lower because of skid collapse].
There may be more detail on the NTSB page [I have not refreshed my memory on this one].
This was one of the last instances I expected Bell to cough up the cash.
No doubt it was more complex than it seemed at the time.
