The U.S. Army awarded Bell Helicopter a contract to modify an additional 27 OH-58D aircraft under the Kiowa Warrior Safety Enhancement Program (SEP). These 27 aircraft will form Lot 12 of the Kiowa Warrior SEP. Work on the aircraft was scheduled to begin in April. Completed aircraft are scheduled to be delivered back to the Army at a rate of three per month beginning in September. Bell is currently modifying aircraft in Lot 11 and is on track to complete all work on that lot in June, ahead of schedule. All work is being done at Bell Helicopter's Plant 1 facility in Fort Worth, TX. Work on Lot 12 aircraft is scheduled to be completed in mid-2010. Once the aircraft in Lot 12 have been completed, Bell will have modified a total of 253 Kiowa Warriors on its SEP line.
