## Probable cause

The improper flare which resulted in a hard landing.  A related factor was the instructor's delayed remedial action.

## Sequence of events

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

- Hard landing, descent
  - emergency procedure - simulated, pilot in command(cfi)
  - flare - improper, pilot in command (cause)
  - remedial action - delayed, pilot in command(cfi) (contributing factor)
- Hard landing, go-around (vfr)

## Analysis

The 1,576-hour private pilot was on an instructional training flight with his flight instructor practicing emergency procedures.  A simulated power-off emergency descent was initiated by the flight instructor at 5,000 feet mean sea level (MSL) over the airport.  The pilot successfully  descended and aligned the airplane for final approach to Runway 17 when "an excessive sink rate developed on short final."  The flight instructor directed the pilot to initiate a go-around.  According to the pilot's statement in the NTSB Pilot/Operator Aircraft Accident Report (NTSB form 6120.1/2) he "immediately initiated the go-around by adding power; however the long engine spool-up time led to a hard landing/touch and go."  Weather at the time of the accident was reported to be, winds at 210 degrees and 9 knots, visibility 10 statute miles, temperature 75 degrees Fahrenheit, altimeter 29.93 inches of Mercury.
