Description

A Fokker 100 passenger jet, VH-NQE, suffered substantial damage in a landing accident at Nifty Airport, WA (NIF), Australia. During the final approach, the aircraft encountered windshear and subsequently made a hard landing. The ATSB found that when the aircraft was on approach to land at about 80 ft above ground level, the flight path almost certainly coincided with the strong outflow of a dry microburst, resulting in a performance-decreasing windshear that led to the rapid drop in airspeed, high sink rate, undershoot and a hard landing. Also, the aircraft was not fully configured for an approach in known or suspected windshear conditions, reducing the capability of the aircraft to recover from the high sink rate associated with a microburst event.

Primary Cause

Strong outflow of a dry microburst during final approach, leading to performance-decreasing windshear.Strong outflow of a dry microburst during final approach, leading to performance-decreasing windshear.
