What was found
WHILE DOING A DAILY INSPECTION A 1 3/4 INCH CRACK WAS FOUND IN THE LT WING JUST ABOVE THE INBOARD FLAP BELLCRANK. WE OPERATE A FLEET OF 26 550 SERIES AIRCRAFT WITH A LARGE PORTION HAVING A REPAIR TO THE LT OR RT WING AT ONE POINT OR ANOTHER. I HAVE FOUND SEVERAL WHILE WORKING AT A FBO. MANY OF MY FRIENDS ALSO CONFERM THAT THIS IS A COMMON THING TO THE FLEET. TALKING TO THE FACTORY THEY WANT ONE OF THERE ENGINEERS OR A DER TO HELP IN THE FIX. IT SEAMS TO ME THAT IF THIS IS A COMMON THING THEM WHY CAN'T THE MFG. COME UP WITH A SB AND A REPAIR KIT AS WE HAVE SEEN IN THE PAST ON OTHER LESS COSTLY A/C ?
