Hello Good People!While you await your printed copy, here is the latest pdf file to enjoy. My apologies on being even more tardy. I have a useless nephew who took his drug addiction to the next level and decided to become a quadriplegic. Given his immediate family shares the same moral fiber, my wife and I have had to arrange for his short term and long term care over the past couple of months. Lots of distractions.Now back to Pietenpols.-john-________________________________________________________________________________Date: Fri, 6 Jun 2014 12:16:25 -0700 (PDT)

If I understand you correctly, mine failed similarly a few years ago. Possiblya weak part of the design.

Here is a photo of the sheared bolts - builders here say they've been fatiguedfor a long time as fully rusted and flecks of yellow paint...you can see the shinypart is the only part holding the head onto the bolt - the 3rd bolt's headfell off just as we touched it with the wrench - it looked perfectly A-OK.I've replaced all landing gear bolts today and really impressed with the workmanshipon C-GGLU. Lloyd Stamp did an awesome job of building C-GGLU - the boltsslid in perfectly, no elongated holes, beautifully aligned. The plans show AN3sfor the bracket that holds these cross bars on. We're back in the air tomorrowand i look forward to taking Adrian's Piet to Carmen's fly in breakfast onSunday - it sure is fun to fly!!!JillRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/2014 ... ___Subject: Pietenpol-List: Re: Landing Gear's AN3 bolts sheared - replaced with AN3or AN4?
