Antonio Felix Da Costa has been disqualified from the Misano E-Prix after his throttle damper spring was not found in conformity with the regulations. 

This means today’s victory has been given to Oliver Rowland who now leads the drivers’ standings.

Da Costa was found to have an old specification throttle damper spring in the car, which Porsche says has been in the car since the beginning of season nine.

A statement from the FIA said: “At post-race scrutineering the Throttle Damper Spring mounted in car 13 during the race was not found in conformity with one of the 3 optional items declared in the GEN3 Spark Catalogue, published in Bulletin 1 of the Misano E-Prix.

“The team manager and the representative of the manufacturer explained that since the beginning of season 9, they have not changed the Throttle Damper Spring. The team manager accepted that the sealed part, as shown in the attachment of the Technical Report 13 was mounted in car 13 and was sealed in the presence of the chief mechanic of the team.

“The team manager stated also that on the Spark list (pedals) the sealed part is not listed. He explained that normally changes of the Spark catalogue are highlighted so everybody can see the changes, but not the removements. The FIA Technical Delegate confirmed this procedure.

“The representatives of Spark confirmed that this part was listed on the part list of the Gen2 cars, but not on the current Gen3 car. They also confirmed that the removal of parts from that catalogue are not highlighted nor cancelled.

“The competitor is responsible for the conformity of the car and even if there is no performance advantage the car has to comply with the Regulations (Article 1.3.3 of the International Sporting Code).

“Due to this result, the car has to be disqualified from the race and the next cars move up in the classification.”

Porsche can appeal the decision made by the FIA, but it is unclear if the German manufactuer will do so, but early indications from the camp are that they are heavily considering it.
