Just found it within Lasors:
Under Section F, Part 4 entitled "Multi-Pilot Aeroplane Type Ratings" the following is encountered under the "Pre-requisite conditions for training:
An applicant for the first type rating for a MPA shall provide evidence that the following requirements have been met:-
a) have completed t least 100 hours as pilot-in-command of aeroplanes.
b) have a valid multi-engine Instrument Rating (Aeroplanes) within the last 5 years from the date of expiry of the rating. This is only a requirement for an initial MPA type rating and not subsequent type ratings;
c) hold a certificate of satisfactory completiono f a multi-crew co-operation (MCC) course (this requirement is not applicable to those who have attended a TRTO course which includes MCC). For full details on the MCC Course and MCC credits can be found at Section F10.
d) have passed the professional flight crew examinations at ATPL level
Hope this helps.
