## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT DIRECTIONAL CONTROL WHILE LANDING IN CROSSWIND CONDITIONS.

## 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 - crosswind (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (contributing factor)
  - lack of total experience, pilot in command
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - soft
  - ground loop/swerve, pilot in command
  - landing gear - collapsed

## Analysis

THE PRIVATE PILOT WAS LANDING THE TAILDRAGGER AIRPLANE ON RUNWAY 13, WITH WINDS REPORTED OUT OF 220 DEGREES AT 12 KNOTS.  HE STATED DURING THE APPROACH 'EVERYTHING LOOKED FINE.  I HAD THE RIGHT WING DOWN AND WAS USING LEFT RUDDER TO MAINTAIN RUNWAY HEADING.  I WAS ABLE TO FLY DOWN THE RUNWAY CENTERLINE WITHOUT A PROBLEM SO I GRADUALLY PULLED THE POWER BACK, FLARED SLOWLY AND LANDED ON THE CENTERLINE.'  THE PILOT REPORTED AS THE AIRPLANE DECELERATED, IT BEGAN TO VEER TO THE RIGHT, AND HE '...COULD NOT STOP IT.' THE AIRPLANE DEPARTED THE RIGHT SIDE OF THE RUNWAY AND SKIDDED INTO SOFT DIRT, COLLAPSING THE LANDING GEAR.  THE PILOT STATED HE '...SHOULD HAVE ANTICIPATED USING LOTS OF BRAKE PRESSURE....AS THE AIRPLANE SLOWED, THE RUDDER EFFECTIVENESS DECREASED AND I LOST CONTROL.'  THE PILOT'S WRITTEN STATEMENT INDICATED A TOTAL FLIGHT TIME OF 74 HOURS, OF WHICH 63 HOURS WERE IN THE ACCIDENT MAKE AND MODEL 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 19921025043199A](https://openairdocs.org/incident/19921025043199A), Oct 25, 1992: Bbavia 7ECA, Carroll, IA, Substantial damage. Pilot lost directional control of aircraft on crosswind landing. Veered off runway. Gear collapsed in soft dirt.

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.
