Main trade-off	Exceptional access and payload for short island or utility routes, but slow cruise and commercial maintenance are costly.	Useful six-seat cabin and turbocharged redundancy, but full-fuel payload is limited and two ageing engines create major reserve exposure.	Efficient and modern for a twin, but early diesel engine and gearbox support can create significant risk.
