    Default AMOC for re-sealing struts

    For those that have struts that some foll decided to drill them for fairings and door stops there is hope!

    I just got an advance copy of my AMOC that allows me to inspect, treat, and reseal my struts to eliminate the repeditive inspections. If anyone wants help in applying for a similar AMOC for your aircraft, let me know and I'll be glad to give you some guidance.

    I am most certainly interested. Four hours with a fabric tester kills my hands every other year. Brian heidt

    To be clear this is an Alternate Means of Compliance for sealed Univair or Airframes struts that have been drilled by someone ignorant to the AD and knowledge to keep the struts sealed? It does not apply to original Piper struts?

    Steve, that is correct. My Clipper project came with a set of Univair struts (large fork) previously sealed struts that someone drilled for fairings and door catches. The AMOC is to have them inspected, treated for corrosion, then TIG the holes and that makes them sealed struts again. I still need to get the Field Approval to weld the bushing for the fair leads to use them on the PA-16 (that went in the mail yesterday) as the front struts are actually PA-20/22 struts. I hadnít heard of anyone getting an AMOC for this in the past, so I figured it would be good info for the group.

    This would not apply to original struts. I think Jenson had an STC to seal the original struts, but they still had the small forks. Not shire if anyone else had an STC to seal the originals and put the larger forks on them.

    Atlee Dodge and Jensen had an STC to seal the original struts and modify them for larger forks. The problem was they never got the repetitive punch test done away with although it was required every 5 years vs 2 if memory serves me correctly.
