Pilatus B-4
Procedures for safe disassembly of the glider and
then putting the various components into the
trailer.
(Trailer 6)

Initial Preparation:

Pick a loading location with sufficient room behind the trailer. As each wing stores in the
trailer on the opposite side from its location on the glider, the glider must be positioned well
back from the trailer to provide the necessary maneuvering room for the wings while being
maneuvered into the trailer.
The trailer may be left hitched to a prime mover, or simply parked with the wheels chocked.
However, neither is absolutely necessary. As all component loading is done with the trailer
box tipped such that the rear end is firmly on the ground, this provides plenty of stability.
Remove the lower pin securing the trailer box tilting mechanism immediately below and
behind the scissor jack that tilts the trailer box. A hammer and a brass drift punch will be
found in the box on the floor in the front of the trailer. Use these tools to remove the pin –
do not hammer directly on the pin with the hammer – always use the brass drift
punch! Use the crank also found in that box to tilt the trailer box until the rear of the box is
firmly on the ground.
Remove the rear door of the trailer and store along the right side of the trailer. (Suggest the
door be "leaned" on the fender on that side, and not "leaned" against the side of the trailer
itself, as this is likely to "scratch the paint.") Caution: During door removal, tip the top
of the door out a bit and disconnect (if not already disconnected) the wiring plugs
to be found immediately behind the left side of the door at about mid-level.
Remove the plywood loading ramp if found on the floor immediately inside, and position this
ramp with the metal tabs over the two small metal posts in the back sill of the trailer bed.
(This ramp may have previously "been found" up front when that end of the trailer was first
unloaded.)

Extraction of the tail-plane trolley and fuselage dolly:

Remove the pip pin from the lateral sway brace located on the top center of the trolley
frame. (Immediately store the pip pin back in either piece of hardware – don't "carry it
away.")

  • Page 1 Pilatus B-4 Procedures for safe disassembly of the glider and then putting the various components into the trailer. (Trailer 6) Initial Preparation: Pick a loading location with sufficient room behind the trailer. As each wing stores in the trailer on the opposite side from its location on the glider, the glider must be positioned well back from the trailer to provide the necessary maneuvering room for the wings while being maneuvered into the trailer.
  • Page 2 Remove the wing nut from the threaded pin found protruding through the aluminum angle on the right end of the red painted trolley base. (Immediately “capture” this wing nut with the clip found on the short chain located immediately adjacent – don’t “carry this away” either.) Extract the tail-plane trolley, and maneuver to a position directly behind the left side of the trailer, such that the removed tail-plane may be installed in the trolley.
  • Page 3 With a person on each wing tip, lift and wiggle as necessary to enable removal of the top center main spar retention pin. With one person on the wing tip and two on the root (left wing) remove the lower main spar pin and carry the wing away from the glider and maneuver tip first toward the trailer.
  • Page 4 Dress the long tie down strap over the “lift handle” in the forward edge of the vertical fin and thread through the cam buckle on the other strap. Tighten. Loading of the tail-plane trolley: Unhook the carabiner from the eye on the side of the fuselage and stow in the eye bolt on the top rail of the trolley.
