Eaton's Engine-Driven Pump Upgrade Improves Component Reliability, Reduces Lifecycle Maintenance Costs for Allegiant Air's MD80 Fleet

IRVINE, Calif. … Diversified industrial manufacturer Eaton Corporation recently launched an engine-driven pump upgrade for Allegiant Air’s MD80 fleet that is improving component reliability and performance while reducing lifecycle maintenance costs.

“Allegiant Air selected Eaton’s upgrade package based on the value our products bring to long-term component and aircraft performance,” said Eric Alden, vice president of customer support for Eaton’s Aerospace Group. “We are pleased to extend a proven product line to Allegiant Air that offers the highest levels of reliability, quality and customer support.”

Engine-driven pumps are the primary source of hydraulic power for primary and secondary flight controls and various aircraft utility systems. In 2005 Eaton introduced a major MD80 pump upgrade to the industry that nearly doubled reliability performance and significantly reduced lifecycle maintenance costs.

Eaton recently approached Allegiant Air with a value proposition to upgrade all of the airline’s MD80 pumps to the latest configuration to reduce maintenance costs and improve aircraft dispatch performance.

Eaton tailored a program to meet Allegiant Air's requirements to complete fleet pump upgrades in 12 months and launched the project in March. Through the end of May, all elements of the upgrade project were on schedule and on budget.
