## Analysis

THE PILOT STATED THAT HE ENCOUNTERED SEVERE WINDSHEAR ON APPROACH TO LANDING AT THE RYAN AERODROM AIRPORT. HE APPLIED FULL POWER AND PULLED THE NOSE UP TO THE BEST ANGLE OF CLIMB ATTITUDE, HOWEVER HE COULD NOT ARREST THE SINK RATE AND HIT THE RUNWAY IN A SLIGHTLY NOSE DOWN ATTITUDE. THE AIRCRAFT PROPELLER CONTACTED THE RUNWAY AND THE AIRCRAFT NOSED OVER INTO THE INVERTED POSITION. TO HIS KNOWLEDGE THE AIRCRAFT DID NOT STALL. THERE WERE NO REPORTS OF WIND GUSTS IN THE AREA AT THE TIME OF THE ACCIDENT. DURING A TELEPHONE CONVERSATION WITH THE AIRPORT MANAGER AT THE RYAN AERODROM AIRPORT ON 7-21-86, THE PILOT WOULD OFTEN BUZZ THE AIRPORT TO CLEAR AWAY ANY ANIMALS BEFORE LANDING AND THOUGHT PERHAPS THE PILOT HAD NOT ALLOWED ADEQUATE ALTITUDE.

## 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 19860720034759A](https://openairdocs.org/incident/19860720034759A), Jul 20, 1986: Amtr PARRAKEETA4C, Midland, TX, Substantial damage. Aircraft hit the runway in a slightly low attitude. Pilot claims a downdraft caused him to initiate a go around.

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.
