Rob, Slick/Unison service bulletins will probably supercede GFA AD's and there have been a few.
Serial numbers and date of manufactuer have different effects but most refer to points assembly, brushes and service intervals. SB3-08A is a good place to start. Motor gliders with one magneto require different inspection intervals. A major improvement years ago was the setting of the points by the "E" gap. Just to complicate things further Slick/Unison have been taken over by TransDigm Group.

This is the only AD listed in our form 2 pack about the magneto and only seems to mention 500 hour internal examinations. Could you let me know the number of the AD that requires 250 hour inspections? We will certainly have to make sure it is included in the Dimona (and maybe others) list of applicable AD's.

An internal inspection is required every 250 hours.

If anything more than minor resistance pull it back out and try and get it thinner. Cut the cable, pull it out then lay it out with the end on a screw attached to a piece of wood or some thing solid. Swage one end of the new cable ...lay it out along side of the old cable and use a marker pen at the other end to indicate where the swage will ultimately go then feed it back in and swage when back inside. Replacing all cables so often is VERY conservative but we found that the rudder pedal cables that go through some sharp turns can, in fact need it. I thought the Slick magneto was every 500 hours.. We haven't managed to get to 5 years. cheers Rob PO Box 129, Lawson, NSW, 2783. mobile 0429 493828 ............................................. ------------------------------------------------------------------------------ From: neville swan <[email protected]> To: [email protected] Sent: Tue, 4 May, 2010 1:53:09 PM Subject: [DOG mailing list] Dimona It seems that my recently imported H36, despite having had an annual plus an export C of A (at a cost of 1700 euros) and declared airworthy, is overdue for the two yearly strip/inspection of the Slick magneto and also the ten yearly replacement of the rudder and tail wheel cables - a bit disappointing! Anyone done these jobs and can warn me of any potential problems? Also could do with a foolproof method of attaching a drawstring to the rudder cables before pulling them out. Cheers, Neville.
