How long do AIP grant assurances remain in effect after project completion?

• A. 10 years
• B. 15 years
• C. 20 years
• D. 25 years

Answer: (C)

The correct duration for AIP (Airport Improvement Program) grant assurances to remain in effect after project completion is 20 years. This period is established to ensure that the benefits derived from federally funded projects are maintained over a significant timeframe, allowing for the appropriate use of the facilities developed through these grants. Thus, airports must comply with the specified assurances related to the project, including the maintenance and operation of the facility as intended.

This 20-year period serves as a safeguard for federal investments, ensuring that the facilities funded through the AIP grants continue to serve their purpose effectively and remain accessible to the public. This long duration also supports accountability and encourages responsible management of federal funds allocated for airport improvements.
