An aircraft lost control during a takeoff roll in poor weather conditions, skidding into the Cromlin river. All three crew members were injured and the airframe was destroyed.

What happened

The incident occurred while the aircraft was attempting to depart under poor weather conditions. The initial phase of the takeoff roll was conducted using visual references; however, visibility levels proved insufficient for safe continued operation. In response, the captain transitioned the flight controls to instrument references. Following this switch, control of the airplane was lost. The airframe subsequently skidded and swerved off the intended path before coming to rest in the Cromlin river.

Findings

The investigation noted that the loss of control occurred immediately after the transition from visual to instrument flight rules during the takeoff roll. As a result of the impact with the water, all three crew members sustained injuries. The aircraft suffered extensive structural damage and was declared beyond repair.

Probable cause

Loss of control following a switch to instrument references due to insufficient visibility during the takeoff roll in poor weather conditions.
