From LASORS (available on the CAA website). Section F9.1
TRANSFER OF TYPE/CLASS RATINGS
FROM A NON-JAA STATE LICENCE
Type Ratings
(Aeroplane/Helicopter)
A type rating endorsement on a licence issued by a
non-JAA State may be transferred to a UK issued pilot’s
licence, subject to:-
i
) 500 hours flying experience as pilot on type,
operating as P1 or P2 appropriate to the rating
required (PUT time may not be counted).
ii) Operational experience as pilot on type within the
preceding 5 years.
iii) Pass a Proficiency Check on type.
iv) Have met the requirements of JAR-FCL 1.250/
2.250, 1.251 and 2.255 as applicable, including
knowledge of aeroplane performance appropriate
to that type (please refer to Section F4 -
Knowledge of Aeroplane Performance).
Applicants who hold a type rating but do not meet the
experience requirements above will be required to
complete a course of training at an approved TRTO.
The CAA may consider a reduction in the amount of
training required to take account of previous
experience on type, subject to a recommendation in
writing by the Head of Training. Applicants will be
required to pass the written theoretical knowledge
examination and a Licensing Skill Test (LST).
Hope that helps.
