Removal and installation of the undercarriage (main wheel)
4.4.1
General
Warning:
A gas strut is installed outside the landing gear box to compensate the
mass of the landing gear. The landing gear may retract by itself when unlocked
by the force of the gas strut, especially when the glider is not in the normal
position. So when working at the landing gear, make sure that inadvertent
retraction of the landing gear is prevented.
Removal of the gas strut in the landing gear control system:
Use a screw
clamp to pre-stress the gas strut sufficiently so that the bolts can be removed.
