In
July 1994 the B-17 came in before its scheduled winter maintenance due to
a problem with contaminated fuel purchased in California. Fearing an
emergency airworthiness directive from the F.A.A. against the aircraft
engines that obtained this fuel, the bomber returned to Florida early from
its national tour.
All
engines, fuel and oil tanks, accessories and hoses were removed and
overhauled at the request of the petroleum company.
During
this project it was decided that American Aero should pull the wings from
the fuselage and inspect the spar terminal ends for cracks and corrosion.
Gary
Norville takes up the story “We used a crane to lift the B-17 and then
retracted the main gear, setting it down on 24 inch jacks and cradles.
Once this was accomplished we removed the outer wing panels and main wing
panels. All eight terminal ends were removed and inspected. The terminal
ends were then cleaned, NDT’d, nickel plated and baked to relieve
hydrogen cracks using visual and x-ray inspection. No damage was found in
the spar or terminal ends and they were re-assembled.”
The
wings were re-installed and once again the B-17 was back on its main gear.
In January 1995 the project was complete and Nine-o-Nine
was ready to commence its next nation-wide tour. An entire photograph
album was created to document what was found and repaired to maybe help
other B-17
Co-op members if they were faced with the same project.
