the theory sounds good anyway!
Potential Issues:
1. Presumably the capital allowannces can be set against any taxable income?
2. Ease or otherwise of obtaining the finance
3. Running costs of the jet - management fees, pilots, insurance, fuel, parts, downtime, insurance, hangar space etc. Will the income be sufficent to cover these?
4. At what rate do these jets depreciate? Is the notion of a free plane after 8 yrs realistic?
5. Envronmental taxes may be levied transport modes deemed environmentally unfriendly in the next few years, no idea of the amounts etc, but...
6. Legal costs of the consortium, what iif members wish to leave early etc?
7. Rising interest rates, will the finance be individual or consortium based (presumably the jet will be the security and thust will be the latter).
All in all, I'm sure the accountancy firm have looked into all these and the many actual issues and the scheme is probably viable. Good luck (just remember that you should;nt use it too much personally, as that may eat into the consortiums revenue)!
