Who is required to submit Form 5100-126 and Form 5100-127?

Form 5100-126 and Form 5100-127 are specifically required for commercial service airports that enplane 2,500 or more passengers. These forms are part of the Federal Aviation Administration's (FAA) process for funding and managing airport development projects. The forms are essential in assessing the need and justification for federal funding as they provide crucial data regarding airport operations, passenger numbers, and other relevant information.

Commercial service airports that handle fewer than 2,500 passengers, general aviation airports, and private airports do not have this same reporting obligation. This makes it clear that the forms are tailored for larger commercial service airports, which play a significant role in the national air transportation system and, therefore, require more detailed oversight and data collection to ensure federal funds are allocated appropriately and efficiently.
