The US Transportation Department published a four page rule on Jan. 4, according to the U.S. Government Publishing Office.

The rule is focused on Airworthiness Directives; Fokker Model F27 Series Airplanes (Excluding Mark 050 Series Airplanes).

The Department handles nearly all infrastructure crisscrossing the country. Downsizing the Federal Government, a project aimed at lowering taxes and boosting federal efficiency, said the Department should be privatized to save money, reduce congestion and spur innovation.

Notices are required documents detailing rules and regulations being proposed by each federal department. This allows the public to see what issues legislators and federal departments are focusing on.

Any person or organization can comment on the proposed rules. Departments and agencies must then address “significant issues raised in comments and discuss any changes made,” the Federal Register says.
