ATR is the current world leader in regional aviation. In order to maintain its leading role in the turboprop market and to expand its customers' portfolio in the United States, the granting of the Extended Twin-Engine Operations Performance Standards (ETOPS) certification by the Federal Aviation Administration (FAA) has been set as a mid-term goal. The market forecast done by ATR anticipates that 250 ageing turboprops will need to be replaced in the US in the coming years. Additionally, from the operational point of view the US airlines would benefit from significant fuel savings and low operating costs thanks to the introduction of ATR aircraft. Consequently, the purpose of this internship is to perform a feasibility study to prove compliance with the ETOPS capability according to the American Authority. In this framework, a comparison between the American and the European regulation has been completed. The methodology undertaken consisted of gathering all the requirements applicable to ETOPS on the FAA regulation and the identification of the equivalent condition on the European regulation. Afterwards, a study on the impact of the differences has been conducted and a proposal of means of compliance for each different FAA requirement is presented. The final deliverable presented to ATR contains a matrix comparing the FAA and the EASA regulations with the whole ETOPS requirements. Finally, a conclusion evaluating the feasibility of the ETOPS validation was done, stating the needs and future steps to proceed to get the FAA approval for ATR ETOPS capability.
