PT6-34 fuel system conversion fromTwin Otter 300 Series to 400 Series
Fuel System must be converted from a ‘Start Flow Control” to “Flow divider”configuration when switching a PT6A-34 from an old Twin Otter Series 300to the New Twin Otter Series 400
P&WC do not have a Service Bulletin or kit to covert such conversion.
A list of affected components can be sent to customer and conversion canbe made using engine IPC.
