Bell awarded $147 million Marine Corps helicopter maintenance contract
Washington (UPI) Jun 16, 2017 - Bell helicopter Textron has been awarded a $147 million contract for the repair of 35 components used on the UH-1Y and AH-1Z helicopters.

The Department of Defense on Thursday announced the contract, which covers a two-year base period and an option for an additional year. Work will be conducted in Ft. Worth, Texas, and is expected to be completed by June 2019.

No contract funds will be obligated at the time of the award and U.S. Navy funds for working capital will be obligated upon the issue of each individual order. The contract was sole source after one bid was received.

The UH-1Y Venom, an upgraded version of the original UH-1 Iroquois or "Huey", is a multi-role platform that serves as the primary light utility helicopter of the Marine Corps. Variants and upgraded versions of the UH-1 series have been in use since 1959

The AH-1Z Viper is a derivative of the AH-1W SuperCobra, itself part of the Huey family of helicopter platforms, and serves as an attack helicopter for the Marine Corps.

The Viper carries a 20mm chaingun in a rotating turret and can mount 2.75 inch rockets, laser-guided missiles and Sidewinder air-to-air infrared missiles. It features an electronic warfare suite and Forward Looking Infra-Red imaging systems for night operations.

The U.S. Navy on Friday released results of a comprehensive review of reported physiological episodes involving T-45 trainer and F/A-18 fighter aircraft to determine the facts and procedures involved, ordering further steps to reduce the number of episodes experienced by pilots.

The review was meant to determine what factors lead to the incidents, including command, control, and communications, oxygen systems, cabin pressurization, proper maintenance, better monitoring of pilots, and other issues.

Vice Chief of Naval Operations Adm. Bill Moran directed commander of the U.S. Pacific Fleet Adm. Scott Swift to lead the review last April after the Navy grounded T-45 trainer aircraft at several Naval Air Stations.

The CR recommends establishing a single organization within the Navy to study and resolve PE incidents. The command, which is expected to be headed by a "more experienced aviation flag officer," will be responsible for redesigns of oxygen system equipment and the establishment of an integrated life support system program. The program would manage oxygen and cabin pressure systems and physiological monitoring.

Physiological episodes, which include hypoxia from oxygen deprivation, has become a serious issue with Naval and Air Force aviation. All F-35s at of Luke Air Force Base have been grounded indefinitely due to multiple reports of hypoxia, which accounts for over 25 percent of the fleet.
