F. Improved Corrosion Protection
(1)On airplane line numbers 1 through 134, a Corogard corrosion preventive 
finish was applied on all interspar surfaces. But, on airplanes line 
number 135 and on, per PRR 53685, these surfaces get BMS 10-79, type 3 
primer followed by BMS 10-100 (Aeroflex G12E25) corrosion protective 
finish.

RUDDER
1. General
A. Corrosion-resistant  steel (CRES) collars are used with the bolts that attach 
the ribs to the spars in graphite-epoxy rudders. But some airplanes between 
line numbers 224 and 258 could have aluminum collars instead of the CRES 
collars. Corrosion can occur on the aluminum collars.
2. Corrosion Prevention
A. To find out if the airplane has aluminum  collars in the rudder, examine the 
elevators per SB 55-0009. This service bulletin also gives procedures for 
regular inspections and applicable repairs.
