7.30 Technical control
Technical control of the engine after the race
• Race control may require one or more engines to be dismounted to make sure that the conditions of eligibility and conformity are fully satisfied. For obvious reasons these actions never take place at the race track. Therefore the engines are placed in a special box that will be equipped with two numbered seals. A document including both numbers of the seals is overhanded to the driver(s) as a proof his engines are taken into custody. Within 2 weeks after the race the organization will invite the driver/team to be present at the moment the technical control of its engine takes place.
• The driver accepts that it is possible its engine must be partially or completely dismantled so the scrutineers can check if all components are conform the homologation. If this is the case the organization will not reassemble the motor. In case of dispute, only the measuring equipment of the organization is representative.
• The organization has the right to invite a third party at the technical control, but only if this third party offers an “added value” to the control procedure.
• When a driver/team stays absent during the technical control of its engine, that particular engine can’t be checked. In this case the driver will be automatically disqualified for the complete race.
• If the scrutineers make a determination that an engine is not conform to the regulations, the driver will we disqualified for the entire race. Also a disqualification can’t be dropped in the championship ranking.
