Vanguard F-GEJE was chartered by Royal Air Maroc and Air France to carry out a cargo flight from Paris (ORY) to Casablanca. The airplane was to return as flight 3132 to Marseille (MRS) and Paris (ORY). On the return flight at Marseille some cargo was offloaded and new cargo loaded. At 18:08 the airplane taxied to runway 32R and was cleared for takeoff four minutes later. The takeoff was aborted when the crew experienced problems with the flight controls. The crew requested current wind information and after completing some checks requested clearance for departure. During the second attempt to takeoff from runway 32R, the crew experienced control difficulties. The airplane banked to the right until it crashed into the water to the right of the runway. PROBABLE CAUSES (translated from French): “The accident resulted from a loss of control of the aircraft during take-off following a failure (or disconnection) in the control chain of an aileron servo-compensator. This failure (disconnection) most likely occurred when using the thrust reversers on the last landing. This failure (disconnection) appears to be the result of an earlier damage probably located in the control chain of the left aileron servo-compensator, struck by a stepladder after the antepenultimate flight; however, the link between the two elements could not be formally established. Before take-off, the crew did detect the anomaly in the roll controls but performed an incorrect analysis and did not perform all the checks required by the flight manual in this case. The power reduction immediately after take-off exacerbated the loss of control of the aircraft by causing it to stall. The fact that this flight is an instruction flight and the relatively modest experience of this crew on aircraft of this technology were aggravating factors.”
