B737-palonsammutuskone tuhoutunut Länsi-Australiassa

[Ilkka Mäkelä 1 216]

Coulson Aviation-yhtiön Boeing 737-palonsammutuskone on pudonnut tänään tuntemattomasta syystä maahan Länsi-Australian eteläisen rannikon alueella ollessaan sammuttamassa metsäpaloa. Kahden hengen miehistö selvisi lievillä vammoilla mutta kone meni lunastuskuntoon.

The ATSB found that the accident drop was conducted at a low height and airspeed downhill, which required the use of idle thrust and a high descent rate. The delay in the engines reaching go-around thrust at the end of the drop resulted in the aircraft’s height and airspeed (energy state) decaying as it approached rising terrain, which was not expected or detected by the pilot flying. Consequently, the aircraft’s airspeed and thrust were insufficient to climb above a ridgeline in the exit path, which resulted in a controlled flight into terrain. The operator’s practice of recalculating, and lowering, their target drop speed after a partial load drop also contributed to the low energy state of the aircraft leading up to the collision with terrain.
