Which action is NOT typically governed by federal airport grant agreements?

The action that is typically not governed by federal airport grant agreements is the operating hours of the airport. Federal airport grant agreements primarily outline the conditions under which federal funds are provided for airport development and operation, focusing on aspects like construction projects, public access requirements, and the types of commercial activities that can be conducted on airport property.

Federal grants often stipulate how funds can be used, including the obligation for airports to maintain certain standards regarding construction and public access. They may also regulate which types of commercial enterprises can operate on the premises to ensure compliance with federal standards and promote fair competition.

However, operating hours are generally determined by the airport authority or the governing body of the airport based on local demand, operational considerations, and community needs. This allows for flexibility in managing the airport's operational capabilities in response to varying levels of air traffic and service requirements. Therefore, it is not a standard condition included in the federal grant agreements, which focus more on funding allocation and compliance with federal regulations.
