Charter/Taxi (Non Scheduled Revenue Flight)

The failure of the glider pilot to utilize his transponder and the high closure rate of the two aircraft, which limited each pilot's opportunity to see and avoid the other aircraft.

Controlled flight into terrain.

A technical problem occurred on a fuel supply line shortly after takeoff, at an altitude below 800 feet, resulting in the immediate failure of the engine that caught fire shortly later. There were no suitable terrain available for an emergency landing in the vicinity, which was considered as a contributing factor.

The crew's failure to properly monitor the airplane's altitude, which resulted in the captain's inadvertent descent of the airplane into water. Contributing to the accident were the foggy weather conditions, and the captain's decision to descend below the decision height without sufficient visual cues.

The pilot's inadequate evaluation of the weather conditions, and his selection of unsuitable terrain (rough water) for takeoff, which resulted in a collision with ocean swells during takeoff initial climb, and a hard emergency landing and a roll over. Factors contributing to the accident were a windshear, rough water, and buckling of the float assemblies when the airplane struck the waves.

The pilot's failure to attain a proper climb rate and to maintain adequate clearance from the terrain during the initial climb in dark night conditions, which resulted in an in-flight collision with terrain.

The investigation determines that the probable causes of this accident to be the following;
• Substandard maintenance that was performed. (Due to the improper flange on the hydraulic line, the hydraulic line came loose from its housing and depleted the fluid from the hydraulic
reservoir).
• Failure of the back up emergency blow down bottle system. It has been determined from inspection that the cable that connects the emergency blow down bottle system in the nose well of the aircraft to the T-handle in the cockpit, exhibited excessive play. Therefore even though the cable was pulled all the way to its fullest extent, it did not allow movement of the pin that would have provided activation of the system. Annual inspection report completed in December 2005 revealed that the portion of the Annual Inspection that required inspection of the emergency blow down bottle was not signed off by the mechanic as having been accomplished. However, the aircraft was returned to service with this discrepancy outstanding.
• Pilot’s lack of qualification and unfamiliarity with this aircraft, its systems and emergency procedures. ( Evidence of falsification of qualification and time requirement exists in pilot’s logbook).
• Pilot’s poor decision making and impaired judgement. (Possibility of impaired judgement due to pilot fatigue).
• Pilot’s failure in assessing the severity of his situation.
• Pilot’s failure to notify ATC of his problem. (Problem was discovered 20 miles prior to the accident).
• Pilot’s failure to properly assess the conditions for landing and maintain vigilant situational awareness while manoeuvring the aircraft after landing. (From post accident inspection, it was noted that the flaps were not extended for the landing. Had it been extended the aircraft glide path as well as the distance required for roll out after landing may have been greatly decreased).
• Pilot’s failure to take immediate action once he realized his predicament. (Pilot stated that after the propeller made contact with the ground, he decided to apply power and go around, but it was too late. Failure to act also can be attributed to possible pilot fatigue as (pilot was out all day shopping and then decided to leave at such a late hour) well as pilot’s unfamiliarity with aircraft systems and performance capabilities).
• Pilot’s failure to request Emergency Service Assistance. Had this service been requested in a timely manner, preparations could have been made to prevent the fire from spreading to the degree in which it did.
