      Frequently it happens that a well maintained plane comes in for one service and you find via discovery more stuff.  This torque tube was coming out for a broken bond and a new one going in.  As this one sits here you can see that no one has looked under the shock bracket in many a year.  Nose Torque Tube

      Notice in the photo above on the upper leg near the center section.  Notice how the paint under the bolt is chipped away.  This indicates that this bond broke.  You can see it a bit clearer on the lower photo.Corroded Torque Tube Receiver

      Did not measure any of the pits but they are deep enough to fail this section.  Good thing another one was going in.

      Cheers

      Hi Roscoe, what is the AMM requirement to inspect the torque tube and nose strut? Is it just a visual, or are you required to remove the nose strut for the inspection? Thanks, Ed

      It is to come out every year and be checked by the checklist (annual / 100 hr).  That said we pull them every 2 years for planes we maintain that are parked outside, and every 3 years for those that are hangared.   It is when they are not checked for years that the metal react and bond.
