What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot flew two passengers from homer (5BL) to Lake Brooks (5Z9). During the descent to landing on short final approach, the PIC initially flew at 60 KTS with a descent of 150FPM rate of descent. Due to the extremely glassy water as well as dividing his attention between inside and outside the aircraft, the PIC lost some depth perception. The airspeed dropped to 53 KTS and 200' per minute rate of descent. At this point the aircraft bounced off the water, the PIC reduced throttle to idle and increased back pressure (pulled back) on the flight controls. This put the aircraft in an abnormally nose high attitude which caused the tail of the aircraft to hit the water surface hard enough to break the horizontal stabilizer control surface.
As the FAA filed it
PILOT FLEW TWO PASSENGERS FROM HOMER (5BL) TO LAKE BROOKS (5Z9). DURING THE DESCENT TO LANDING ON SHORT FINAL APPROACH, THE PIC INITIALLY FLEW AT 60 KTS WITH A DESCENT OF 150FPM RATE OF DESCENT.

THE AIRSPEED DROPPED TO 53 KTS AND 200' PER MINUTE RATE OF DESCENT. AT THIS POINT THE AIRCRAFT BOUNCED OFF THE WATER, THE PIC REDUCED THROTTLE TO IDLE AND INCREASED BACK PRESSURE (PULLED BACK) ON THE FLIGHT CONTROLS. THIS PUT THE AIRCRAFT IN AN ABNORMALLY NOSE HIGH ATTITUDE WHICH CAUSED THE TAIL OF THE AIRCRAFT TO HIT THE WATER SURFACE HARD ENOUGH TO BREAK THE HORIZONTAL STABILIZER CONTROL SURFACE.
