## Probable cause

THE PILOT'S FAILURE TO MAINTAIN THE PROPER DESCENT RATE AND ADEQUATE AIRSPEED DURING THE APPROACH. A FACTOR RELATED TO THE ACCIDENT IS THE LACK OF RECENT TOTAL EXPERIENCE.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Hard landing, landing
  - touch-and-go
  - lack of recent total experience, pilot in command (contributing factor)
  - proper descent rate - exceeded, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)

## Analysis

THE PILOT HAD A PRIVATE, SINGLE ENGINE LAND RATING AND WAS ENROUTE TO TAKE HIS SINGLE ENGINE SEA FLIGHT CHECK.  HE DELAYED AT A LAKE THREE MILES FROM HIS DESTINATION TO PRACTICE SOME TAKEOFFS AND LANDINGS.  WHILE ATTEMPTING A POWER OFF LANDING HE GOT SLOW AND HIGH ON FINAL AND DID NOT ADD POWER IN TIME TO STOP THE SINK RATE RESULTING IN A HARD LANDING.
