What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The PIC stated he had flown the 17 year old subject/passenger on a 8-10 minute sight seeing flight in his CE-150, and had taxied back to the staging area and parked the aircraft with the engine still running as another passenger wished to fly also. There had been no specific briefing on how to deplane the aircraft prior to the flight because the subject had not intended to fly at the time. However, the PIC stated he had delivered a passenger briefing once the subject entered the aircraft.
With the engine still running the pic's son (student pilot and friend of the subject) approached the aircraft from the rear with plans to safely guide her. The subject had attempted to exit the aircraft once before but was told to wait by the PIC. The subject then saw her boyfriend approaching the aircraft, assumed it was now ok, then proceeded to deplane before the PIC could stop her. Leaving the aircraft the subject placed herself dangerously close to the rotating propeller. The pic's son and boyfriend both screamed for the subject to back away from the propeller. As she turned away the propeller struck her on the backside of her left arm.
Initially the subject did not even realize she had been struck; there was very little bleeding and/or pain. The PIC made ensured the subject was eventually seen at the hospital where she received 7 stiches; the PIC estimated the injury to be approximately 3-4" long and 1/4" deep. There were no broken bones or other injuries. A full recovery is anticipated.
As the FAA filed it
THE PIC STATED HE HAD FLOWN THE 17 YEAR OLD SUBJECT/PASSENGER ON A 8-10 MINUTE SIGHT SEEING FLIGHT IN HIS CE-150, AND HAD TAXIED BACK TO THE STAGING AREA AND PARKED THE AIRCRAFT WITH THE ENGINE STILL RUNNING AS ANOTHER PASSENGER WISHED TO FLY ALSO. THERE HAD BEEN NO SPECIFIC BRIEFING ON HOW TO DEPLANE THE AIRCRAFT PRIOR TO THE FLIGHT BECAUSE THE SUBJECT HAD NOT INTENDED TO FLY AT THE TIME. HOWEVER, THE PIC STATED HE HAD DELIVERED A PASSENGER BRIEFING ONCE THE SUBJECT ENTERED THE AIRCRAFT.
WITH THE ENGINE STILL RUNNING THE PIC'S SON (STUDENT PILOT AND FRIEND OF THE SUBJECT) APPROACHED THE AIRCRAFT FROM THE REAR WITH PLANS TO SAFELY GUIDE HER. THE SUBJECT HAD ATTEMPTED TO EXIT THE AIRCRAFT ONCE BEFORE BUT WAS TOLD TO WAIT BY THE PIC. THE SUBJECT THEN SAW HER BOYFRIEND APPROACHING THE AIRCRAFT, ASSUMED IT WAS NOW OK, THEN PROCEEDED TO DEPLANE BEFORE THE PIC COULD STOP HER. LEAVING THE AIRCRAFT THE SUBJECT PLACED HERSELF DANGEROUSLY CLOSE TO THE ROTATING PROPELLER. THE PIC'S SON AND BOYFRIEND BOTH SCREAMED FOR THE SUBJECT TO BACK AWAY FROM THE PROPELLER. AS SHE TURNED AWAY THE PROPELLER STRUCK HER ON THE BACKSIDE OF HER LEFT ARM.
