Although there is a Griffin HAR2 (ex Cyprus cab) based nowadays at Boscombe with RWTS; they never evaluated the Griffin prior to entry into service, and I doubt Boscombe will be involved in the introduction of the new types.
Boscombe did complete a HIRTA Assesment of Griffin HT1 when such checks were flavour of the month, but by that time the aircraft had been in service for some time.
