Yeh the grade of paper is to stop you from damaging the outer glass layer. Probably faster to use an angle grinder with 80 grit paper disk and laminate a replacement layer afterwards but that does require repair qualifications and thus why they want you to use a fine grit paper. Nige.

He said that he believes the terms 'plate' and 'panel' to be synonymous in the translation process. This makes so much better sense when you read the work order. i too was thinking the translation was from German to English but as Col Brock pointed out it is probably from Austrian to English. Nige said that the upper and lower surfaces of the spar tunnel are non structural and that he had cut a large inspection 'panel' out of the lower surface for another task which verifies that. It is the front and rear of the tunnel which is structural. I just had a look at the worker order for the root rib again. i'm cant see any requirement for gelcoat removal inside the wing Ian. It calls for complete removal of the paint from the outside of the root rib, coating with a clear epoxy resin to reseal and and which will enhance crack detection in the outer root rib. the paint removal is a bugger of a job as supposed to be done with 160 grade paper or finer.

In wings we had no gelcote on the inner D section of wing as they speak of removing the Gelcote and we have the hole already cut Ian m On 19 November 2012 17:09, Rob Thompson <[email protected]> wrote: G'day All, The 3000 hour schedule calls to "...Separate upper spar tunnel plate from bulkhead. Leave 10mm rim" Nigel has a bit of experience dealing with translated German. He suggested that this probably means that the upper section of the spar tunnel (which is non-structural) needs to be cut out leaving a lip along the front and rear remaining as a guide for the spars when rigging. Then use the resulting hole for inspection purposes of the upper interior of the structural bulkhead. I am thinking just some appropriately spaced holes and then a bore-a-scope inspection would do the trick. Has anyone done this part of the survey inspection? cheers Rob PO Box 129, Lawson, NSW, 2783. mobile 0429 493828 ............................................. --- On Tue, 6/11/12, Angel Jimenez Martin <[email protected]> wrote: From: Angel Jimenez Martin <[email protected]> Subject: [DOG mailing list] H-36 Service Bulletin Nº 19 To: "[email protected]" <[email protected]> Received: Tuesday, 6 November, 2012, 6:02 AM Hi all, As I said I bought an H-36 Dimona that has been many years parked in a hangar and currently only 120 flight hours.
