20. STANDARD PRACTICES - AIRFRAME
20.00.00 General
This chapter provides standard torque values and safetying procedures that are to be used in all areas
of the aircraft unless otherwise specified. The use of these standard values and procedures will ensure
the security of installation and prevent overstressing of components.
20.10.00 Torquing Procedures
Correct Torquing of fasteners is critical, if a bolt or fastener is too loose it may cause unnecessary
movement resulting in wear or fatigue, while over tightening may cause tensile failure of the bolt, or
crushing of components. Torques should be determined using an accurate torque wrench during
installation. The torque required after the nut is fully on the shaft, but not against the mating surface
should be added to the final torque value.
Special Torquing Procedures
Seat Mast Block Sub Assembly
The Seat Mast Block has special torquing procedures that need to be followed. Drawing 5658 is
supplied showing the required Torque values, as well as the Loctite required.
Figure 18 Seat Mast Block Sub Assembly
Front wheel
The front wheel axle bolts should be torqued to 27Nm on each side, before the locking bolts are
tightened.
