The fatal Accident of this plane is a very sad story that could have been prevented. Like most planes the CL-44 had measures to prevent the control surfaces to fly in the wind. The gustlock system installed by Canadair was deactivated or modified on most CL-44 after the fatal accident of Cargolux CL-44J TF-LLG (c/n 36). It became evident that TF-LLG went down after the gustlock system was activated in flight.
On serial #5 the gustlock system had been deactivated and the crew used wooden makeshift locks. On the 27 of September 1975 the crew of LV-JSY overlooked the lock on the right elevator and during takeoff this caused the elevators to be locked and the plane never got airborne while trying to take-off from Runway 27L. The plane overran and crashed into the west bank of a canal, 960ft from the end of the runway and stopped on the railway tracks, killing 3 crew members and 3 passengers. Two crew members and and two passengers survived.
The question springs to mind how can this be happen. Well first thing that needs to be said is that the pilot who did the walk around did not do it very well. But on the questions: Why did they not test the controls or why did they not abort take-off? The answer is simple. On the CL-44 the pilots did not control the surfaces but a tab who created a aerodynamic effect and moved the controls and if the elevator is locked that does not mean that the tab is locked nor that the pilot would feel any difference on the control and since the controls need airspeed to work the plane was probably to fast before the pilots realised what was going on and an abort take-off was impossible or doomed to go wrong.
