Make sure the trailing edge of the exhaust gate is 0.00 to 0.15 inch below the trailing edge of the midflap.
(c)
If the exhaust gate and the aftflap are not aligned in the limits, adjust the trailing edge of the exhaust gate: 1) Hold the trailing edge of the exhaust gate. 2) Install the rig pin in the FLAP-UP rig pin hole. 3) Remove the exhaust gate pushrod. 4) Adjust the length of the pushrod until the exhaust gate and
the aftflap are aligned in the limit.
