Main trade-off	Efficient and modern for a twin, but early diesel engine and gearbox support can create significant risk.	Useful six-seat cabin and turbocharged redundancy, but full-fuel payload is limited and two ageing engines create major reserve exposure.	A fast, respected and practical piston twin, but two large engines and ageing systems create turboprop-like maintenance exposure.
