Cold Working Fastener Holes Is Now Required
Gulfstream G280 owners with serial numbers 2001-2189 will be required to comply with Service Bulletin 280-57-277 "Cold Working of Holes in Lower Skin Stringer 3 Common to Outboard Feed Tank Lower Bracket". This Service Bulletin calls for an inspection of the stringer around the three fastener holes and the stringer at the lower outboard end of the feeder tank for cracks. If no cracks are found, cold work is to be performed on the holes.
This Service Bulletin has been issued in response to Gulfstream discovering 'the design was found to be insufficiently fatigue resistant, concentrated around three holes'. It is recommended that this task be accomplished concurrently with SB 280-57-182 "Wings - Enlarging Corner Holes on Feed Tank Bracket".
