SPA.SET-IMC.105 SET-IMC operations approval
Regulation (EU) 2019/1387
To obtain a SET-IMC approval by the competent authority, the operator shall provide evidence that all the following conditions have been complied with:
(a) an acceptable level of turbine engine reliability is achieved in service by the world fleet for the particular airframe-engine combination;
(b) specific maintenance instructions and procedures to ensure the intended levels of continued airworthiness and reliability of the aeroplane and its propulsion system have been established and included in the operator's aircraft maintenance programme in accordance with Regulation (EU) No 1321/2014, including all of the following:
(1) an engine trend monitoring programme, except for aeroplanes first issued with an individual certificate of airworthiness after 31 December 2004 that have an automatic trend monitoring system;
(2) a propulsion and associated systems' reliability programme;
(c) flight crew composition and a training/checking programme for the flight crew members involved in these operations have been established;
(d) operating procedures have been established specifying all the following:
(1) the equipment to be carried, including its operating limitations and appropriate entries in the MEL;
(2) the flight planning;
(3) the normal procedures;
(4) the contingency procedures, including procedures following a propulsion system failure, as well as forced landing procedures in all weather conditions;
(5) the monitoring and incident reporting.
(e) a safety risk assessment has been performed, including the determination of an acceptable risk period if an operator intends to make use of it.
To gain EASA SET-IMC approval, operators must demonstrate turbine engine reliability, specific maintenance programs, and crew training. Crucially, robust operating procedures covering equipment, flight planning, normal/contingency scenarios (engine failure, forced landings), and incident reporting are needed. A safety risk assessment, including acceptable risk periods, is also mandatory.
