DaveSoaring Posted April 30, 2012 Report Posted April 30, 2012 I noticed that in the Grob service bulletin regarding the vertical stabilizer noseplate, it says if corrosion is found, remove and replace the noseplate. Is this a part that is through bolted to a plate embedded in the glass or will the noseplate need to be cut out and re-glassed? Anyone have any tips on removing a stuck horizontal stabilizer where the noseplate won't let go of the horizontal stabilizer pin.Thanks, Dave Quote

Michael Haisten Posted May 2, 2012 Report Posted May 2, 2012 Dave,Use a good penetrate oil and give it some time to do it's thing. Then using a hammer and punch, strike the end of the attach bolt a few times. You are not trying to knock the thing off, just shock the attach point to break the seizure. The nose plate is a bolt in part, but you will have to carry out the associated SB to cut an inspection hole in the side of the vertical fin. This work needs to be done by a qualified A&P mechanic. I do not know any of the shops in your area. Make sure they are familiar with composite/fiberglass repair.Michael HaistenAuburn Airplane Works Quote

There is no access so I squirted it along the attach bolt after threading it out. Today we tried forward pressure on the horizontal stabilizer while giving a few taps to the attach plate. Nothing moved. Didn't try tapping the attach bolt, I'll try that tomorrow. Quote
