The problem
THE FUEL TANK STRAPS MAY DEVELOP MICROSCOPIC CRACKS IN THE PLATING OF THE UPPER END LOOP, EXPOSING THE PARENT METAL TO THE ATMOSPHERE. AIR EXPOSURE PROMOTES CORROSION AND MAY LEAD TO PREMATURE FAILURE, ALLOWING THE FUEL TANK TO DROP.
What owners should do
DEFECTIVE STRAPS WILL BE REPLACED WITH VINYL COATED STEEL STRAPS.
