Schweizer (Hughes) 269 Series Helicopters
AD/HU 269/111  Lateral Control Trim Actuator Assembly  8/2005 TX

Applicability:  Model 269C, serial number (S/N) 1865 through 1874 with a prefix of S; Model 269C-1, S/N 0169 through 0191; and Model 269D, Configuration A, S/N 0044 through 0050 with an A suffix, helicopters, with a lateral control trim actuator assembly, part number (P/N) 269A7316-13, installed, except for an actuator assembly containing a number 30 twist drill drilled hole in the lateral trim control housing through the wall of the inner spring tube socket.
Requirement:       1. For Model 269C, S/N 1865 through 1874, with a prefix of S, and Model 269C-1, S/N 0169 through 0191.

                     (a) Inspect the lateral control trim actuator assembly for a scuffmark, indentation, or outer spring guide tube deformation. Inspect for security of the inner spring tube in the socket of the lateral trim control housing by rotating and pulling on the inner spring tube. Examine the resin bead around the base of the inner spring tube and housing socket. Resin should be translucent dark pink in colour to indicate a good bond. Conduct the inspection by following the Procedures in Part I of Schweizer Service Bulletin B-283.1 or C1B- 017.1, both dated 4 March 2005, respectively, as applicable.

                     (b) If a scuffmark, indentation, or deformation exists on the outer spring tube, or the inner spring tube is loose or has motion, or the bonding is separated, remove the lateral control trim actuator assembly; modify the trim control housing and the inner spring tube; and test run the actuator assembly. Modify and test run the actuator assembly by following the Procedures in Part II of Schweizer Service Bulletin B-283.1 or C1B- 017.1, as applicable.

                     (c) If no scuffmark, indentation, or deformation exists on the outer spring tube, or the inner spring tube is not loose, or the bonding is not separated, modify the lateral control trim actuator assembly as required by Requirement 1(b) of this Directive.

                   2. For Model 269D, Configuration A, S/N 0044 through 0050 with a suffix of A.

                    Modify the lateral control trim actuator assembly by following the
