## 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
  - landing gear,normal brake system - undetermined (cause)
  - directional control - not possible, pilot in command
  - ground loop/swerve
- Nose over, landing - roll

## Analysis

PLT STATED THAT IMMEDIATELY AFTER TOUCHDOWN, THE RIGHT WHEEL SEEMED TO DRAG. RIGHT DRIFT WAS INITIALLY CORRECTED BY USE OF OPPOSITE AILERON TO REDUCE WEIGHT ON RIGHT WHEEL AND RUDDER FOR DIRECTIONAL CONTROL. HOWEVER, AS THE ACFT SLOWED WEIGHT SETTLED ON THE RIGHT WHEEL, THE ACFT SWEREVED TO THE RIGHT AND NOSED OVER. POST-MISHAP EXAMINATION OF ACFT BRAKE REVEALED NO DISCREPANCIES.

- [Accident 19841122065209A](https://openairdocs.org/incident/19841122065209A), Nov 22, 1984: Luscom 8E, Oakes, ND, Substantial damage. During rollout had drag on right wheel. Nosed over and fell on back. Unable to determine why brake grabbed.

## Other investigations on N2759K (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 WPR16LA141](https://openairdocs.org/ntsb/WPR16LA141), Jul 17, 2016: Luscombe 8A (N2759K), Minden, NV, substantial damage. Probable cause: The failure of a main landing gear leg during takeoff due to corrosion, which resulted in a nose-over during the subsequent landing on a grassy area.
