## Probable cause

LOSS OF CONTROL ON LANDING ROLL DUE TO THE PILOT'S FAILURE TO MAINTAIN PROPER ALIGNMENT, RESULTING IN COLLISION WITH TERRAIN DURING AN UNCONTROLLED GROUND LOOP/SWERVE.  A FACTOR RELATING TO THE ACCIDENT WAS THE CROSSWIND WEATHER 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)
  - proper alignment - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - ground loop/swerve - uncontrolled, pilot in command (cause)

## Analysis

THE PILOT MADE A WHEEL LANDING IN VARIABLE CROSSWIND CONDITIONS AND THE ACFT GND LOOPED/SWERVED OFF THE RIGHT SIDE OF THE RWY.  WHEN THE ACFT REACHED THE SHOULDER OF THE RWY, THE LEFT MAIN LDG GEAR COLLAPSED AND THE LEFT WING IMPACTED THE GROUND.

## Other investigations on N2746D (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.

Probable cause: The pilot’s exceedance of the airplane’s takeoff performance limitations, which prevented the airplane from gaining sufficient altitude to clear the trees off the departure end of the runway.
