Since I was going to torque the blades to the hub right now this seems important. I might have an old Line Maintenance Manual and old Heavy Maintenance Manual.
Line Maintenance Manual MMM-MT-B_14-11-19
Heavy Maintenance Manual MMM-MT-E_16-06-13
Both of these show on “ 01-12-00 Torque Values “ that an M8 bolt is to be torqued to 25Nm +/- 3Nm
The latest 25 hour 100 hrs Protocol AG-F-PCA-MT-EN-V2 shows on Page 1 Rotor System to check torque the blade to hub bar bolts/nuts to 20Nm +/- 5Nm and points to the Job Card 62-11-00 4-3
When I go to the Job Card 62-11-00 4-3 on both the Line and the Heavy Maintenance Manuals I find it shows in step 5 to torque those bolts to 15Nm.
That’s 3 different torque values for the same bolt. So which is it?
