Ensure to review dent limits on presentation 10, slides 35-37
W = width of the dent Y = depth of the dent width over depth, divide and see if number is greater than 30 = acceptable Use W/Y to determine if the dent is within limits If W/Y > 30 = within limits If W/Y < 30 = not within limits The dent must be smooth Sharp creases, gouges and cracks are not permitted Pulled or loose fasteners are not permitted
