Serviceability is not good but I guess not to many bits are original on helicopters of their age!
The main problem is access to spares. Since they [supposedly] "saved money" by cancelling the PBH they are at the back of an often very long queue for bits.
If ever they get around to order some T3s they will probably never replace the whole fleet before the yet to be seen replacements are at 10,000 hours!
Will they ever buy T3s? The T4/P4 must be around the corner.....
