You will need to look at Commission Regulation (EC) No 2042/2003
Annex III.
But I don't think it will be happy reading for you especially 66 A70 shown below unless you qualify.
Conversion provisions
(a) The holder of a certifying staff qualification valid in a Member State, prior to the date of entry into force of this Part shall be issued an aircraft maintenance licence without further examination subject to the conditions specified in 66.B.300.
(b) A person undergoing a qualification process valid in a Member State, prior to the date of entry into force of this Part may continue to be qualified. The holder of a qualification gained following such qualification process shall be issued an aircraft maintenance licence without further examination subject to he conditions specified in 66.B.300
(c) Where necessary, the aircraft maintenance licence shall contain technical limitations in relation to the scope of the pre-existing qualification.
Hope it helps
