As said above the hire status of this aircraft puts it into a grey area legally however it can be operated until you reach 2000 hours + 20% or 12 years +20%.
Pushing aircraft past the 20% mark is not usually economic in the long run (standby for the person who as done 10,000 hours without touching their O-320!) so have the money at the ready to do the overhaul before the 20% mark is reached if a lot of work is required to keep the engine running.
When overhaul time comes there are only three companies in the UK who are worth using in terms of quality of work, price & after sales service, a quick search on these pages will find you the best ( not the cheapest) deal.
