4.2.4 Derigging
Derigging follows the reverse of rigging.
Water ballast and fuel tanks in the wings must first be emptied. Fuel in
wing tanks can be simply transfered to the fuselage tank or emptied
directly using the pump system (see 4.2.3.3) in reverse.
Disconnect the connectors for the wing fuel tanks (optional).
Lock the airbrakes.
For disassembling the securing pins of the wings the tool W 38/2 must be
screwed into the bolt completely.
The brass part of the tool will then disengage the securing of this bolt.
It is recommended to leave the securing bolt in the right wing as long as
you derig the left wing.
