OLATHE, Kan., June 9, 2011 /PRNewswire/ -- Butler National Corporation (OTCQB: BUKS), a leader in the growing global market for structural modification, maintenance, repair and overhaul(MRO) has obtained a Supplemental Type Certificate(STC) from the FAA for autopilot modernizations to the J.E.T. FC-110 Autopilot used in most Learjet Model 20 Series airplanes.

"Globally, there are more than 400 Lear 20 Series jets that would benefit from the modernization of the autopilot boards in the FC-110 Autopilot.  The STC allows Butler National to produce replacement autopilot boards that function exactly as the original boards, but enhance autopilot reliability.  These boards should allow more consistent functionality of the FC-110 autopilot", said Craig Stewart, President of the Aerospace Group at Butler National Corporation.

Mexico is one of our largest global opportunities.  Constantino Jimenez, CEO of Servicios Profesionales De Aviacion said, "There are 80 aircraft in Mexico that would benefit from the J.E.T. FC-110 Autopilot modernization."  Based in Guadalajara, Servicios Profesionales De Aviacion is Butler's exclusive authorized installation center for our modifications in Mexico. "These upgrades are critical to improved flight safety and reliability in Mexico and Latin America.  Butler is a leader in Learjet modifications throughout Mexico and South America so it is natural that we continue to partner with them on the installations of this important new safety feature", added Jimenez.

Net income was $867,000 compared to net income of $642,000 for the same period in fiscal 2010. The increase in net income was primarily due to continued success in the aircraft modification segment.
