## Sequence of events

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

- Loss of engine power, go-around (vfr)
  - throttle/power control - improper use of, dual student (contributing factor)
  - supervision - inadequate, pilot in command(cfi) (contributing factor)
- Forced landing, descent - emergency
- Hard landing, landing

  - airspeed - not maintained, pilot in command(cfi) (cause)
  - stall - inadvertent, pilot in command(cfi) (cause)
- Complete gear collapsed, landing
  - landing gear - overload

## Analysis

ENG PWR LOSS OCCURRED WHEN THE INSTRUMENT STUDENT ADVANCED THE THROTTLE TO DO A GO-AROUND WHEN THE ACFT WAS TOO HIGH TO LND ON RWY 5 FOLLOWING A SIMULATED INSTRMT APCH. THE INSTR TOOK CONTROL OF THE ACFT AND ABOUT HALF-WAY DOWN THE RWY, AT ABOUT 300 FT AGL, DID A LEFT TURN TO LAND NEXT TO RWY 31. THE ACFT LANDED HARD AND COLLAPSED THE LNDG GEAR. THE ENG EXAM DID NOT DISCLOSE EVIDENCE OF MALFUNCTION. THE ACFT HAD MADE A LONG APPROACH AT LOW POWER SETTING PRIOR TO THE SUDDEN APPLICATION OF POWER.
