Required Actions
Inspect the nose-main gear interconnection tube for corrosion every 50 hours of operation. Apply ANG-3a grease to the unpainted aft end. Replace the tube if pitting or scaling is found.

Applies to Models V and V2 Aircraft. Inspect the nose-main gear interconnection tube located in the nose wheel well for evidence of corrosion and apply ANG-3a grease to the unpainted aft end every 50 hours of operation. Since the aft end of the tube slides through a trunnion just aft of the wing spar any pitting or scaling of the tube surface in this area may result in binding and failure of the landing gear retracting system and necessitates replacement of the tube. Where climatic conditions promote accelerated corrosive action, as in coastal regions, the tube should be inspected during each daily line check. (Culver Service Memorandum dated September 25, 1946, covers this same subject.) FOOTER:
