OLD VIKING Posted July 14, 2012 Report Posted July 14, 2012 Hi Guys, we installed the inspection cover on LX-CRJ, using the Grob supplied retainer ring and cover according to their instructions. We traced the hole to be cut with a compass, cut it out with a Dremel high speed cutter (as used for tiles) and scraped away the foam carefully about 0.75 in on the inside, using a vacuum cleaner to such the debris out during the scraping. Installed the retainer ring with epoxy, making sure ring was secured with a long string, in case it dropped inside. Using the aluminium bars and screws, plus four small pieces of wood to hold the ring in place during cure. Checking that the ring fit correctly for a flush fit of the cover afterwards. The installation job took a couple of hours, but needs a day of curing and tempering with an electric fan heater. Then a little paint and rubbing down. Looks now as if Grob would have done it. OK, one may discuss whether or not a borescope inspection hole would do the same. But at the end of the day, covering a small hole (or maybe two) is about the same amount of work. At least our G109B is to standard. Grobs price for the cover kit of around 300 Euro is a bit expensive, but what is not expensive for airplanes ? Quote
