## Sequence of events

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

- Nose over, landing - roll
  - landing gear,tailwheel - vibration
  - landing gear,tailwheel assembly - overload
  - brakes(normal) - excessive, pilot in command (cause)

## Analysis

DURING THE LANDING ROLL THE TAILWHEEL REPORTEDLY OSCILLATED BRAKING THE SHOCK STRUT LUGS ALLOWING THE TAIL OF THE ACFT TO CONTACT THE SOD RUNWAY. THE PLT APPLIED HARD BRAKING AND THE ACFT NOSED OVER. THE PLT REPORTED NOTHING WAS WRONG WITH THE TAILWHEEL LOCKING MECHANISM.

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

- [Accident 19840711031909A](https://openairdocs.org/incident/19840711031909A), Jul 11, 1984: Ayres 600S2C, Lambert, MS, Substantial damage. Tailwheel oscillated on landing causing shock strut to break. Aircraft nosed over in attempt to stop.

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.
