Under the regime of the President, Major General Muhammadu Buhari (retd), the Presidential Air Fleet has so far cost taxpayers a total of N41.9bn, contrary to the promise Buhari made during the 2015 presidential election campaigns to reduce waste in governance by downsizing the presidential fleet. As of October 2016, when the Presidency last made a public inventory of the PAF, the fleet included 10 aircraft, namely one Boeing Business Jet (or Air Force One) 737, one Gulfstream G550, one Gulfstream G500, one Hawker 4000, two Falcon 7X, two AgustaWestland AW139 helicopters, and two AgustaWestland AW101 helicopters.
