PRM1, vicinity Annemasse France, 2013

Summary

On 4 March 2013, a Beechcraft Premier 1A stalled and crashed soon after take off from Annemasse. The Investigation concluded that the loss of control was attributable to taking off with frozen deposits on the wings which the professional pilot flying the privately-operated aircraft had either not been aware of or had considered insignificant. It was found that the aircraft had been parked outside overnight and that overnight conditions, particularly the presence of a substantial quantity of cold-soaked fuel, had been conducive to the formation of frost and that no airframe de/anti icing facilities had been available at Annemasse.

Description

On 4 March 2013, the professional pilot of a privately-operated Beechcraft Premier 1A (VP-CAZ) which had just taken off from Annemasse for Geneva in day Visual Meteorological Conditions (VMC) lost control of the aircraft and it crashed just outside the aerodrome perimeter. The aircraft was destroyed by the impact and a post crash fire and two of the three occupants were killed and the third ejected from the aircraft during the impact sequence and seriously injured. Before final impact with the ground, the aircraft had hit trees and buildings, substantially damaging the roof of a nearby house.

Investigation

An Investigation was carried out by the French BEA. Although not a mandatory requirement, it was found that the aircraft had been fitted with a Cockpit Voice Recorder (CVR) which, whilst damaged, was successfully downloaded and provided very useful information, validated in respect of time using two sources of radar returns from the aircraft.
