Work is under way at Bell Helicopter [TXT] on an Army contract for the conversion of an OH-58A cabin into a D-model cabin.

In April 2009, the Army exercised a contract option to have Bell Helicopter convert one OH-58A cabin into a new OH-58D cabin and also complete the non-recurring engineering effort required to establish a cabin build line.

The creation of a cabin build line would enable the Army to acquire new OH-58D cabins from Bell to replace Kiowa Warrior aircraft whose cabins have been damaged beyond repair.

The first cabin conversion is scheduled for delivery to Corpus Christi Army Depot (CCAD) next year, the company said.

In May, the Army issued a sole-source solicitation to Bell Helicopter for the conversion of additional OH-58 cabins. As many as 66 cabins could be required to support the Army’s objective to replace combat losses and damaged aircraft.

Bell also is supporting CCAD with crash damage repairs on OH-58D aircraft. One Kiowa Warrior cabin has already been repaired and delivered to the Army. Two additional cabins are undergoing repairs. As work on each cabin is completed, it is shipped to an AMCOM Aviation Field Maintenance Directorate site for installation of dynamic components.

Work also continues on the final lot of aircraft in the OH-58D Safety Enhancement Program (SEP). In March 2010, the Army awarded Bell a contract to modify the final 30 OH-58D aircraft scheduled to enter the Kiowa Warrior SEP program. The final aircraft are scheduled to be completed by the end of 2011. When Lot 13 is complete, a total of 371 Kiowa Warriors will have been modified to the SEP configuration.

To date, the U.S. Army’s fleet of Kiowa helicopters has accumulated more than 600,000 combat flight hours and approximately two million total flight hours.
