Aircraft involved

Probable cause & findings

The pilot's inadequate airspeed control during a glassy water landing, which resulted in an excessive sink rate, and a hard landing.

Factual narrative

The pilot was landing the float-equipped airplane at a remote lake. He stated that during the initial approach, he noticed the lake was extremely glassy. He set up for a glassy water landing with an indicated airspeed of 60 knots, and a descent rate of 100 to 200 feet per minute. After he crossed the shoreline, he noticed his airspeed had decreased to between 50 and 55 knots, and his rate of descent was more than 200 feet per minute. He added power to correct the condition, but the airplane hit the water hard and bounced. He said that he started to go around, but decided that his angle of attack was too high, and he reduced the power and let the airplane contact the water again. The airplane bounced again, then settled into the water and came to a stop. During the landing the airplane sustained substantial damage to the left horizontal stabilizer. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot was landing the float-equipped airplane at a remote lake.
