Brief Description:  FT-60 & Wing Walk

Removed the rivets holding the F-1048F mounting bracket for the FT-60 flow transmitter. Mounted the FT-60 to the bracket using AN4-16A bolts. Placed the FT-60 into the tunnel and made a trial tubing run to go from the aux fuel pump outlet to the FT-60 inlet which is offset above the pump outlet by almost 1 inch. With this trial tubing run, the FT-60 is too far forward to connect tubing to the outlet with a 90 deg. bend up, as the tubing hits the front firewall brace before making the full 90 deg. bend.

Loosened the hose clamps holding the pump and filter to their F1048-D brackets and determined that by rotating the pump and shimming it I should be able to bring the outlet into alignment with the FT-60 inlet and then use the short FUEL-00003 connector from Van's to connect the pump outlet to the FT-60 inlet with room to connect the line to the FT-60 outlet for the run to the firewall fuel fitting. Ordered a FUEL-00003 fitting from Van's. (Had to call Van's parts dept. since this item does not show up on their website.)

NOTE: While I initially thought I could use 90 deg. tube fittings in the inlet and outlet of the FT-60 to fit the unit into the space available, I realized that this would negatively impact the accuracy of the FT-60. Good practice when installing flow sensors of any size is to allow at least 5 pipe diameters of straight run pipe before and after the flow element in order to ensure laminar flow through the flow element. (Pipe bends just ahead/behind a flow element will cause turbulent flow through the metering element with a negative impact to the meter accuracy.)

Installed the wing root fairing stiffeners F1099-D to the F1099-A Wing Root Fairings by dimpling and then back riveting them to the fairings. (50 rivets per fairing by 2 fairings).

Checked the left horiz. stabilizer wing tip and found it still rubbed the elevator. Sanded the fiberglass installed earlier to provide better clearance and then applied a thin layer of new resin with fibers to seal the entire face.
