Task Instructions
1. Apply lubricant liberally to threads and shank of the screws.
2. Mount the magnetometer to the mount bracket using 4x screws (6C50MTT3), 4x washers (NAS1149CN632R), and 4x nuts (MS21043-06).
3. Torque nuts to 8.0-9.5 in-lbs. Ensure at least one full thread is protruding from the nut.

Note:
If the D9142P screws do not engage properly, remove one washer and replace with ring terminal as shown in Figure 246.
5. Using isopropyl alcohol, clean surfaces where lubricant will be applied.
6. Apply lubricant liberally to threads of the studs.
7. Mount the magnetometer-mounting bracket assembly with harness facing outboard, onto the three studs located on the wing spar. Secure using 3x nuts (MS21043-08) with 3x washers (NAS1149CN832R).
