Cobham said it has been awarded a potential $7.1 million contract from the Defense Logistics Agency (DLA) to overhaul and upgrade Nitrogen Inerting Units (NIUs) for the AH-64 Apache helicopter.

The work will be performed by Cobham Life Support in Davenport, Iowa, beginning in 2013.

The OBIGGS fulfils a critical aircraft safety system role by displacing fuel tank vapors with inert nitrogen gas, reducing the risk of explosion.

In September 2012, Cobham received a five-year Indefinite Delivery, Indefinite Quantity (IDIQ) contract valued at some $15 million to manufacture OBIGGS NIUs for Army AH-64 Apache helicopters.

More than 1,500 Apache helicopters with Cobham NIUs have been delivered worldwide.

Cobham Life Support president Kelly Coffield said: “This award reflects Cobham’s unrivaled decades of experience in the design, development, delivery and support of fuel tank inerting systems, ranging from depot repair to equipping and training customers to fully maintaining products at their own facilities.”

Cobham OBIGGS systems have logged more than six million flight hours total experience including 12 international customers, the company said. Cobham can tailor the modular range of proven OBIGGS to fit a wide range of applications.
