## Probable cause

DELAY OF THE FLIGHT INSTRUCTOR (CFI) IN MAKING A GO-AROUND AND HIS FAILURE TO ATTAIN SUFFICIENT AIRSPEED TO CLIMB AFTER TAKING OFF AGAIN. THE TRANSMISSION WIRE (POWER LINE) AND HIGH VEGETATION WERE CONTRIBUTING FACTORS.

## Sequence of events

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

- In flight collision with object, go-around (vfr)
  - emergency procedure - simulated, pilot in command(cfi)
  - touch-and-go - initiated
  - go-around - delayed, pilot in command(cfi) (cause)
  - airspeed - not obtained, pilot in command(cfi) (cause)
  - proper climb rate - not attained
  - object - wire,transmission (contributing factor)
- In flight collision with terrain/water, takeoff
  - terrain condition - high vegetation (contributing factor)
- Nose over, other

## Analysis

DRG AN INSTRUCTIONAL FLT, AN EMERGENCY LANDING TO AN ARPT WAS DEMONSTRATED, SIMULATING AN ENG FAILURE. THE INSTRUCTOR (CFI) RPRTD THAT DRG A SUBSEQUENT GO-AROUND, THE ACFT FAILED TO FLY OUT OF GROUND EFFECT BEFORE REACHING A CORN FIELD AT THE END OF THE RWY. THE ACFT BEGAN TO SETTLE OVER THE CORN FIELD AS IT WAS APCHG POWER LINES. REALIZING THE ACFT WOULD NOT CLIMB OVER THE POWER LINES, THE CFI OPTED TO FLY UNDER THE WIRES. HOWEVER, THE TOP OF THE VERTICAL STABILIZER CONTACTED & SEVERED THE LOWERMOST WIRE. THE ACFT THEN CONTACTED THE GROUND, BOUNCED, SETTLED IN A LOT WITH TALL WEEDS & NOSED OVER. NO PREIMPACT ANOMALIES WERE FOUND IN THE AIRFRAME OR ENG THAT WOULD HAVE CONTRIBUTED TO THE OCCURRENCE.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19891014040259A](https://openairdocs.org/incident/19891014040259A), Oct 14, 1989: Cessna 172M, Cedarburg, WI, Substantial damage. Unable to climb out on a sfl elected to go around under wires. Vertical fin hit wire and aircraft crashed inverted.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
