## Analysis

THE CFI AND HER STUDENT WERE PRACTICING LANDINGS ON RWY 10 WITH WINDS REPORTED AS 090 DEG AT 5 KTS. THE STUDENT WAS ON THE CONTROLS, FLARED TOO HIGH, AND THE ACFT BOUNCED AT TOUCHDOWN. THE CFI TOLD HIM TO ADD POWER TO RECOVER FROM THE BOUNCED LANDING. THE STUDENT ADDED FULL POWER AND ALLOWED THE NOSE OF THE ACFT TO RISE TOO HIGH. THE CFI TOOK THE CONTROLS AND LOWERED THE NOSE TO COMPENSATE. THE STUDENT THEN PULLED OFF ALL POWER AND THE ACFT LANDED HARD. THE CFI ANNOUNCED THAT SHE HAD THE CONTROLS BUT THE STUDENT STAYED ON THE RUDDER PEDALS. THE CFI WAS UNABLE TO OVERRIDE HIS INPUTS, AND THE AIRCRAFT SWERVED LEFT, DEPARTED THE RWY, AND AND STRUCK A PARKED CESSNA 210, DAMAGING BOTH AIRCRAFT.

## 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 19881206053069A](https://openairdocs.org/incident/19881206053069A), Dec 6, 1988: Cessna 172N, Denver, CO, Substantial damage. Student bounced, added power and nosed up. Took off power, hit runway, and veered into parked aircraft.

## Other investigations on N6356D (2)

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.

- [NTSB FTW98LA198](https://openairdocs.org/ntsb/FTW98LA198), Apr 25, 1998: Cessna 172N (N6356D), Parker, CO, substantial damage. Probable cause: a fractured #1 exhaust valve rocker arm stud, which subsequently resulted in loss of engine power and a forced landing. The lack of suitable terrain in the forced landing area was a related factor.
- [NTSB DEN90LA101](https://openairdocs.org/ntsb/DEN90LA101), Apr 27, 1990: Cessna 172 (N6356D), Englewood, CO, substantial damage. Probable cause: THE PILOT LANDED WITH A TAILWIND, AND COST CONTROL OF THE AIRPLANE DURING ROLLOUT.
