Complete structure inspection
on rigged sailplane
1 - Verify condition of sailplane external surfaces.

2 - Inspect cockpit against possible loose items, that
might enter into-, and lock control system.
X
X
3 - Inspect seat pan condition, and verify of rear seat
locking and adjustment.
X
X
X
4 - Verify unrestricted operation of aileron and airbrake
control system - to do so, disassemble cover on
control stick at front seat as well as rear seat pan, and
check fuselage interior against foreign objects.

5 - Check condition of pilot safety harnesses.

6 - Check condition of canopy perspex for transparency,
scratches and cracks.
X
X
X
7 - Check reliable operation of canopy locking.
X
X
X
8 - Verify emergency jettison of canopy by test.
X
X
9 - Check correct connection between sailplane units
and reliable locking at joint points.

10 - Check the backlash in joints at wing-fuselage
connection. This is accomplished after previous
removal of wingtips: long or short (plane) or winglets.
Backlash in joints is verified by rapid moving the wing
tip with moderate force.
In case of excessive backlash, these are perceptible in
a form of mutual displacements of mating elements
and possibly audible knocks.

11 - Verify backlash at stabilizer-fuselage connection
–
analogous to check in wing-fuselage connection.
X
X
12 - Verify backlash in elevator and rudder hinges
–
possible backlash is perceptible when pulling with
varying force at trailing edge.
X
X
13 - Measure backlash value at all joints in fittings of main
units (item 3.4.3.) and at control surface hinges
(item 3.4.4.).
X
14 - Verify correct operation of cockpit controls and
measure resistance to motion of these circuits
(item 3.3.).
X
X
X
15 - Verify backlash in aileron and stabilizer control system
– this is accomplished by measurement of play on top
of control stick grip (item 3.4.1.).
