bulkhead. It has holes for the elevator control pushrod and the rudder control cables. It has a cut-
out on the right side for a cable conduit.
N. Ring-Bulkhead #2
The ring bulkhead #2 is a rigid GFRP molding. It bonds to the fuselage shell half way along the rear
fuselage. It has a guide bearing for the elevator control pushrod and holes for the rudder control
cables. It has a cut-out on the right side for a cable conduit.
O. Ring-Bulkhead #3
The ring bulkhead #3 is a rigid GFRP molding. It bonds to the fuselage shell just forward of the
vertical stabilizer. It has holes for the elevator control pushrod and the rudder control cables. It has
a cut-out on the right side for a cable conduit.
P. Ring-Bulkhead #4
The ring bulkhead #4 is a rigid GFRP molding. It bonds to the fuselage shell below the vertical
stabilizer. It has a very large cut-out for the elevator control pushrod, the rudder control cables and
a cable conduit.
Q. Vertical Stabilizer Lower Rib
The vertical stabilizer lower rib is a rigid GFRP molding. It bonds to the fuselage shell at the bottom
