When Greg Herrick, who collects antique airplanes, wanted to restore a 1937 Fairchild aircraft, he struggled to get ahold of the technical drawings for the plane.
The Federal Aviation Administration (FAA), which stores the information, told him it couldn't release the records, claiming that they contained trade secrets.
Herrick, who owns the Golden Wings Museum at the Anoka County-Blaine Airport, which houses nearly 30 vintage airplanes dating back to the "Golden Age of Aviation" between the two world wars, viewed it as a challenge.
Fifteen years later, following a lawsuit that he brought against the FAA which eventually reached the U.S. Supreme Court, Herrick obtained the documents.
More recently, Herrick, who lives in Minneapolis, helped write a related amendment to the FAA Air Transportation Modernization and Safety Improvement Act of 2012, which Congress passed last month.
Dubbed "The Herrick Amendment," the federal legislation orders the FAA to keep the technical documents for more than 1,200 different types of historic aircraft and to make the information available to the public for non-commercial uses, he explained.
It's good news to aviation history buffs.
Previously, even though only a handful of the original manufacturers are still around, the blueprints for many vintage airplanes were kept under wraps or even destroyed.
