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.

On December 6, 2015 at approximately 13:27 pm PDT, a Cessna 206 experienced a propeller blade failure in flight. The aircraft was identified as N9150M. It was on its 4th flight of the day and was operating with four parachute jumpers on board. At approximately 7000 feet MSL, there was a very loud ?bang? Followed by violent shaking of the aircraft. The jump instructors recognized the situation as an emergency and immediately clipped onto their students and exited the aircraft in under 30 seconds. As the jumpers exited the aircraft, the PIC cut the throttle and evaluated the effect, at this point unaware that the propeller had failed. The PIC noticed the decrease in RPM decreased the intensity of the vibration, and cut the mixture to the engine shutting it down completely. As the propeller RPM slowed to a wind milling state the PIC was able to see a blade was missing. Once the propeller stopped the aircraft behaved normally in a power-off state, and the PIC secured the aircraft for an emergency landing. Aircraft landed slightly beyond the runway numbers on center-line with enough momentum to exit onto taxiway b between 8L and 8R.

As the FAA filed it

ON DECEMBER 6, 2015 AT APPROXIMATELY 13:27 PM PDT, A CESSNA 206 EXPERIENCED A PROPELLER BLADE FAILURE IN FLIGHT. THE AIRCRAFT WAS IDENTIFIED AS N9150M. IT WAS ON ITS 4TH FLIGHT OF THE DAY AND WAS OPERATING WITH FOUR PARACHUTE JUMPERS ON BOARD. AT APPROXIMATELY 7000 FEET MSL, THERE WAS A VERY LOUD ?BANG? FOLLOWED BY VIOLENT SHAKING OF THE AIRCRAFT. THE JUMP INSTRUCTORS RECOGNIZED THE SITUATION AS AN EMERGENCY AND IMMEDIATELY CLIPPED ONTO THEIR STUDENTS AND EXITED THE AIRCRAFT IN UNDER 30 SECONDS. AS THE JUMPERS EXITED THE AIRCRAFT, THE PIC CUT THE THROTTLE AND EVALUATED THE EFFECT, AT THIS POINT UNAWARE THAT THE PROPELLER HAD FAILED. THE PIC NOTICED THE DECREASE IN RPM DECREASED THE INTENSITY OF THE VIBRATION, AND CUT THE MIXTURE TO THE ENGINE SHUTTING IT DOWN COMPLETELY. AS THE PROPELLER RPM SLOWED TO A WIND MILLING STATE THE PIC WAS ABLE TO SEE A BLADE WAS MISSING. ONCE THE PROPELLER STOPPED THE AIRCRAFT BEHAVED NORMALLY IN A POWER-OFF STATE, AND THE PIC SECURED THE AIRCRAFT FOR AN EMERGENCY LANDING. AIRCRAFT LANDED SLIGHTLY BEYOND THE RUNWAY NUMBERS ON CENTER-LINE WITH ENOUGH MOMENTUM TO EXIT ONTO TAXIWAY B BETWEEN 8L AND 8R.
