Procedures for safely removing the various components from the
trailer, and for assembly of the glider
Initial Preparation:
Pick a 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 fuselage must be positioned well back
from the trailer to provide the necessary maneuvering room for the wings while being
extracted and installed.
If practical, leave the trailer hitched to the “prime mover” during the entire extraction
process, as this will provide good stability. If for some reason this is not practical, then
chock both trailer wheels securely.
Open front door, and remove all ancillary items as may be found inside (tow bar, wing
wheel, wing stands, tie down equipment, etc.). If these items are left inside, they may tend
to “slide down” as the trailer body is tipped. The spare tire and items in the box need not be
removed, as these items are “captured.”
Untie the rope securing the fuselage dolly forward.
Remove the lower pin securing the trailer bed 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 bed until the rear of the bed is
firmly on the ground.
Remove 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 the wiring plugs to be found immediately
behind the left side of the
door
at about mid-level.
Remove the plywood loading ramp to be 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.
Extraction of the tail-plane trolley:
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.”)
