Background
The Chief Pilot visited the island three days prior to the accident flight and conducted an inspection of the Aircraft Landing Area (ALA), finding it in good condition. However, over the following three days, rainfall occurred, which created soft patches in the runway surface that were not present during the earlier inspection.
Operational Planning
To compensate for the degraded runway conditions, the operator decided to split the total load between two aircraft. This strategy was intended to provide more margin for the take-off operation. The pilot of the GA-8 subsequently calculated that the available runway length would be sufficient for the aircraft to complete the take-off, based on the load and anticipated performance.
Take-off Attempt
During the take-off roll, the GA-8 encountered the soft patches and wet grass on the runway. These surface conditions significantly reduced the aircraft's acceleration, preventing it from reaching the necessary take-off speed within the confines of the available runway. As a result, the aircraft was unable to become airborne and the take-off was not completed.
Findings
The soft patches and wet grass on the runway surface were the factors that prevented the aircraft from completing the take-off. No further details were provided.
