    Default Inspection ring question

    Hello, itís been a while since I posted. Wanted to see if this is normal. I have had two inspection covers on the bottom of my wings depart the plane: one last year and one last week. Both times when I investigated, the inspection ring was cracked in half and the glue attaching the ring to the wing had let go from the wing fabric. It looks like that creates enough flexibility for the tabs on the cover to pull through the fabric. My plane was a new built with ceconite/poly fiber 5 years ago. Any thoughts about this? Build issue? Normal wear and tear. Does tab orientation make a difference. I have been told by some to have the tabs perpendicular to the airflow, others say parallel, others say it doesnít matter. Just getting tired of buying new inspection covers.

    Upper right hand coroner box labeled SEARCH Type in INSPECTION COVER. Lots of threads on them.

    Yep, unfortunately a common issue. Did they put a fabric doily over the plastic inspection rings? they usually last longer with a fabric doily installed at recover. I run the tabs parallel to the slip stream and have even added a #4 PK screw through the plate and plastic grommet.

    Here are some good Google search results using " lost inspection cover fix site:shortwingpipers.org"

    Thanks. I didnít recall hearing anyone say anything about this in the past 5 years I have been following the board. I am guilty of not searching this time. Assume I had something unique happening. Didnít cross my mind to check.

    Irritating it keeps happening but I guess it make me feel better to know that it isnít operator error. I thought I was doing something stupid to make this happen so often. Never had another plane shed inspection covers like this one.
