Summary
We propose to adopt a new airworthiness directive (AD) for certain Beechcraft Corporation Model G58 airplanes. This proposed AD was prompted by reports of fuel leaks due to fuel cells that did not properly fit in Model G58 airplanes. This proposed AD would require inspecting for and replacing, as necessary, certain fuel cells. This proposed AD would also require inspecting and replacing parts, as necessary, of the left and right fuel system installations and correcting torques on fuel system fittings; and prohibit future installations of certain fuel cells. We are proposing this AD to correct the unsafe condition on these products.
