Just a note regarding the Andair fuel system fittings.  On my Legacy, there had been a infrequent smell of Avgas on approach when the gear went down.  I thought it was the venting on the wing bottom having spotted traces of blue from the naca vent.  More recently, I detected the smell on the ground when I would open the canopy.

During the latest condition inspection I removed the sides covering the Andair in/out ports to find the left return banjo covered in blue stain.  The A&P reported is was loose and retorqued to the Andair spec.   None of the 4 Banjo fittings were lockwired and the Andair spec shows that they should be.  I have 422 hours on the airframe.
