## Probable cause

THE FAILURE OF THE PILOT TO CONFIGURE THE ACFT FOR LANDING (LOWERING OF FLAPS) AND MAINTAIN AIRSPEED ABOVE STALL DURING FINAL APPROACH FOR LANDING.

## Sequence of events

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

- Loss of control - in flight, approach - vfr pattern - final approach
  - airspeed(vs) - not maintained, pilot in command (cause)
  - lowering of flaps - not performed, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE FLT DEPARTED CHEHALIS, WA, ON A VFR FLT TO BOUNDRY BAY, CD, AND THE PILOT LANDED AT PUYALLUP, WA, WHEN HE ENCOUNTERED ADVERSE WEATHER EN ROUTE. AFTER A DELAY, THE PILOT TOOK OFF TO CONTINUE THE FLT.  THE ACFT RETURNED TO THE ARPT AFTER A FEW MINUTES IN FLT AND ENTERED THE TRAFFIC PATTERN FOR LANDING.  WHILE ON FINAL APPROACH AT A LOW ALTITUDE AGL, THE ACFT STALLED, DESCENDED NOSE DOWN AND IMPACTED THE GROUND AT A PRIVATE RESIDENCE.  THE FLAPS WERE IN THE UP POSITION IN THE WRECKAGE.

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.
