## Discrepancy

THIS FUEL SELECTOR HAS 3 POSITIONS THAT HAVE DETENTS, LT, RT, AND OFF.  IT WAS DETERMINED THAT DURING FUEL MX ON THIS FUEL SELECTOR THAT IF THE SELECTOR IS MOVED JUST OFF OF THE DETENT IN THE LT OR RT POSITION, IT WILL ALSO FEED THE ENGINE FROM THE OPPOSITE TANK THAT IS NOT SELECTED.  IT WOULD BE SIMILAR TO A BOTH SELECTION IN MFG ACFT THAT HAS A BOTH SELECTION.  EACH FUEL TANK IS INDEPENDENT OF THE OTHER IN THIS ACFT.   MFG SN 21060909 ALSO OWNED BY THIS COMPANY WAS GROUND OPERATED TO CONFIRM THAT THE FUEL SELECTOR WOULD CONTINUE TO SUPPLY FUEL TO THE ENGINE IN A POSITION OFF THE LT OR RT DETENT AND IT WAS CONFIRMED THAT IT DID.
