To remove pitot mast probe, remove the two rivets fastening it to the wing strut and pull it out from
the strut far enough to disconnect the pitot line.
For details of the Dynon pitot, refer to Section 6.22.
The static probe is fixed and cannot be removed. Limited access may be available through the fin
top strobe mount (where equipped)
– otherwise an access hole must be cut into the fin. Consult
Jabiru Aircraft or our local approved representative before making access holes.
In all cases, installation of tubing will be simplified if a guide wire is drawn in as the tubing is
removed. When replacing tubing and fittings, tighten connections firmly, but avoid over-tightening
and distortion of fittings or tubing.
