## Probable cause

THE PILOT LANDED WITH A TAILWIND, AND COST CONTROL OF THE AIRPLANE DURING ROLLOUT.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - weather condition - tailwind (contributing factor)
  - flight into known adverse weather - continued, pilot in command (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)
- Nose over, landing - roll

## Analysis

THE PRIVATE PILOT WAS COMPLETING A CROSS COUNTRY SOLO FLIGHT. SHE SAID SHE HAD WEATHER INFORMATION THAT A FRONT WAS DUE AT THE SAME TIME SHE ESTIMATED HER ARRIVAL. SHE SAID THAT ON SHORT FINAL, SHE ENCOUNTERED WINDSHEAR. DURING LANDING ROLL, SHE SAID THE TAIL LIFTED AND THE PLANE NOSED OVER. THE PLANE CAME TO REST INVERTED ON THE RUNWAY, WITH DAMAGED VERTICAL STABILIZER AND DAMAGE TO THE TOPS OF THE WINGS.

## 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 19900427013029A](https://openairdocs.org/incident/19900427013029A), Apr 27, 1990: Cessna 172N, Denver, CO, Substantial damage. Wind gusty on final due approaching front then reversed and blew over aircraft on landing roll after slowing down.

## 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.
