As previously stated, the EIR appears to be for aeroplanes only. Converting an ICAO IR to a Part-FCL one has always been based on the recommendation of an ATO (but, in the UK - see CAP 804 Section 4 Part Q). No-one, for example, with few hours and an IR gained on a light single in benign conditions, is going to pass a Part-FCL ME IRT without considerable extra training. Whether you think it should be necessary or not, there can be little doubt that European (most states anyway) standards of instrument flying are among the highest in the world.
