Replacement Of Control Rods Ball Joint Ends - Magni Gyro M16C Ordinary Maintenance Manual

3. With a 9/16' ring wrench and a 3/4' wrench (or n°19) slightly tighten the bolt pn NAS 628‐30;
4. Try again the control along the longitudinal axis (pitch up and down);
5. Go on repeating steps 3 and 4 till a good compromise between reduction of forks' play and easiness of
flight control is reached.
The same operation has then to be done for the control along the transversal axis, with tightening of the bolt pn
NAS 628‐52. The picture 3.6/3 shows the axes on which the rotor head movements are articulated.
3.8 MAINTENANCE AND CHECKS OF CONTROL LINE
(See Fig. 3.8/1 ‐ 3.8/2)
Due to its strong building and to the high reliability of the materials used, the control line does not need short term
maintenance, just pre‐flight checks.
NOTE:
All the bolts of the control line (1) are marked after having been tightened at the factory, so as to
highlight incidental and unwished movements of the bolt‐nut coupling.
