StuOstrander Posted January 21, 2013 Report Share Posted January 21, 2013 Noseplate and Elevator Push/Pull Tube Inspection AD’s Robert Mudd made up and sent me an epoxy kit that allowed me to add a 5/8†diameter (16 mm) inspection hole in the vertical stabilizer, precisely per Grob specifications, with absolutely minimal fuss. The kit included the specified resin, catalyst, and flocking, and… rubber gloves, a mixing spatula, and complete instructions. The epoxy resin and catalyst arrived pre-measured. It was only necessary to mix the resin and catalyst, add the cotton flocking to the designated consistency, and apply the mixture. No measuring! The Kit provided more than enough material without being excessive. Robert made up the custom repair kit for a total cost, including shipping, of $35. What a relief. For G109B owners, add another $15, and Robert will also send the rivet and “O†ring required to reassemble the Elevator Push/Pull tube. Removing the Push/Pull tube is easily accomplished. If you prefer, you can ship the removed rod to Robert and he will perform the inspection and, if indicated, repair/replace the push/pull tube. If you send him your unit, Robert will perform the required inspection and return a serviceable assembly to you. Robert will also provide the appropriate documentation with the returned unit. The FAA used Grob factory prices in their estimated costs: · $78 for the rivet, “O†ring, and LPS-3 (vs $15 rivet and “O†ring from Robert) or · $680 for a new, or rebuilt, assembly if there is corrosion present on the thin wall tube. (Robert does not know his replacement cost yet, if the tube is unserviceable, but is confident it will be better than Grob’s.) I want to publicly thank Robert for eliminating the major headaches we confronted on these two AD’s. Robert Mudd Composite Aircraft Repair P.O.
