Two U.S. senators are accusing the Air Force of trying to violate the law with recent proposals to ground the A-10 aircraft.

Sen. Kelly Ayotte, R-N.H., and Sen. Saxby Chambliss, R-Ga., have sent a letter to the Secretary of the Air Force demanding answers.

The two Republicans say the Air Force is allotting no flight hours for A-10s based at Nellis Air Force Base in Nevada, and has cancelled the modernization program for the plane, as well as ended other programs.

Those changes would go into effect in October, which is the beginning of the new fiscal year.

The National Defense Authorization Act passed last year, saying the Air Force “may not retire, prepare to retire, or place in storage” any A-10s during calendar 2014.

The senators say the action by the Air Force is a violation of the NDAA.

Air Force officials say they want to mothball the plane in order to save money.
