THE MLG DOOR ACTUATOR DAMPING MECHANISM **CONF ALL
MODIFICATIONS
MODIFICATION CLASSIFICATION MAJOR 153655J3430 MINOR None NOTE : As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES There have been failures of Main Landing Gear (MLG) door actuators Part Number (P/N) 114122006/7/9/10/11 and 114122012 (Pre and Post Mod. No. 38274J2894) causing slow door operations and in some cases causing a jammed door.
Investigations have shown that the issue is linked to damage seen in the damping mechanism components and the release of debris from these components.
Testing showed that debris resulting from the internal damping mechanism components damage, may contaminate the outlet restrictor resulting in a hydraulic blockage of the actuator. This hydraulic blockage may prevent full opening of the main landing gear door under powered or gravity extension.
This Service Bulletin has been issued to inform operators of the issue of GE Aviation Service Bulletin No. 114122-32-105.
This Service Bulletin introduces a new and improved damping mechanism. The old Spirolox ring of the actuator extend end is removed and replaced with a locking ring. The retaining ring is also replaced by a spacer ring and the damping ring has been repositioned. The piston rod is also modified to allow installation of the new locking ring.
These changes will make sure that the axial loads generated during operation can be reacted effectively and within the design limits of the components.

SERVICE BULLETIN
SUMMARY Additional improvements to the design include:
- new bearings with improved installation process (new swaging procedure)
- a new improved scraper seal
- vent holes have been drilled in the scraper seal area damping housing for inter-seal pressure relief purposes
- torque tightening procedure of the ring nut in the earth-end and in the damping housing are revised following in-service reports.
Embodiment of this modification will cancel the repetitive inspections requested in All Operators Telex A320-32A1390 and ISB A320-32-1390 (these inspections are m andated by EASA AD).
Embodiment of this modification and accomplishment of Service Bulletin No. A320-31-1414 will cancel OEB 44 issue 4.
