5. Secure the shelf to the fuselage with one layer of 3.0 in. wide, 2 bid strips at each corner above
and below the shelf. The lay up is shown in Figure C-23.
6. The shelf installation must be fully cured before proceeding with the magnetometer installation.
Using the elevator control tube as the aircraft centerline reference, project a parallel line on to the
magnetometer shelf. The parallel line serves as an indication of the aircraft's forward direction,
as demonstrated in Figure C-24. The alignment of the magnetometer is critical and needs to be
within 0.5° of the aircraft's forward direction.
