Have flown on a brand new T2 air ambulance, although when it was initially delivered to the trust I work for, it had horrendous problems with recurring chip lights.
Before too long the gear box was changed... Not good considering they had just parted with £3,000,000 for it.
Feed back from the pilots has been extremely good since, and it is certainly easier to work on than the preceding BK105 in terms of space, versatility, reduced limitations improved H&S issues, conveying escorts and so on.
