Aviation Accident Summary SEA99LA023

BELLINGHAM, WA, USA

Aircraft #1

CGHFD

Piper PA-34-200

Analysis

The pilot noted that he was on approach to the runway and about 30' to 50' above ground when he encountered a wind shear downdraft so severe that all loose things in the cockpit flew up to the ceiling. He believed that he must have been crabbing at the time of touchdown, and the side forces at the time of the landing broke the right main landing gear above the wheel/axle casting. The airplane sustained buckling of the right wing and buckling at the rear of the cabin. Control tower personnel who observed the landing characterized it as a very hard landing. Visual meteorological conditions prevailed at the time of the accident, however winds were at 30 knots, gusting to 41 knots.

In a written statement, he noted that he "was on approach to the runway and about 30' to 50' above ground when he encountered a wind shear downdraft of major proportions, so severe that all loose things in the cockpit flew up to the ceiling...." The pilot believed that he must have been crabbing and the side forces at the time of the landing broke the right main landing gear above the wheel/axle casting. The airplane sustained buckling of the right wing and buckling at the rear of the cabin. Bellingham ATC tower controllers noted that they observed the airplane make a very hard landing.

Probable Cause and Findings
