open end spanner.
b) The lock, in extended position, is by means of the gas strut on the
landing gear box and additionally by a locking rubber buffer in the
cockpit. The clearance between the locking latch at the handle and the
front end of the rubber buffer should be 0.5 to max. 1 mm (.02 to max.
.04 in.) with the spring suspension of the undercarriage fully extended.
Adjustment can be made at the mounting of the rubber buffer.
A torsion-spring is installed to keep the handle in the locked position.
