Important Information to Properly Spec Your TSIO-550-C

To ensure proper configuration for your airframe, we will confirm the following before shipping:

Aircraft Make and Model:
Confirm whether the engine is for a Columbia 400, Cessna TTx (T240), or Piper PA-46-350. Each may have unique accessory case or alternator configurations.
Electrical System:
Is your aircraft configured for 12-volt or 24-volt operation? Most certified airframes use 28V (24V nominal), but we’ll verify exact alternator and starter requirements during quoting.
