The thing that will 'kill off' the Raven I (as we know it) will be a move by the oil industry to kill off 100LL.
Jet fuel in lower cost (now) and the rise of the JetA1 eating internal combustion engine is just beginning.
Whaddyathink to the 12yr/ 2200hr rebuild gradually re-engining the 44 fleet with a diesel buring Jet A1.
No carb there, either ....
