29-3, Steps 1, 2, 3, & 4

Using the technique employed to curve the F-1046 Middle Fuselage Longerons, curve the F-1013-R Forward Fuselage Longeron between the "start of curve" mark and the "end of curve" mark. The curve must match the F-1046B Longeron Bending Template within a sixteenth of an inch. Repeat this step to curve the F-1013-L Middle Fuselage Longeron.

Clamp the F-1013-R Forward Fuselage Longeron to the F-1046B Longeron Bending Template. Match the Forward edge of the longeron bending template with the "start of curve" mark and flush the long edge of the longeron bending template with the vertex of the Forward Fuselage longeron. Match-Drill #40 the Middle Fuselage longeron using the longeron bending template as a drill guide. Repeat this step to match-drill the F-1013-L Forward Fuselage Longeron.

Clamp the F-1013-R Forward Fuselage Longeron in a padded vise at the "forward twist mark". Twist the Forward Fuselage longeron with a crescent wrench to obtain the dimension shown in Figure 3. Clamp the Forward Fuselage longeron at the "aft twist mark". Repeat the process using the twist direction shown in Figure 1 to obtain the dimension shown in Figure 3.

Debur the F-1013-L and -R Forward Fuselage Longerons.
