Liebherr and Horizon Air have signed an agreement covering the overhaul of the landing gear systems on board the airline’s Embraer 175-E1 aircraft fleet. The campaign is scheduled to begin in 2027.
Liebherr Aerospace Saline, Inc., Michigan (USA) and Horizon Air, Inc. with headquarters in Seattle, Washington (USA) have reached a definitive agreement for landing gear overhaul and systems maintenance on Horizon Air´s Embraer 175-E1 fleet.
Program overhauls will commence in 2027, and the landing gears will undergo complete “restoration” in compliance with the Embraer Maintenance Review Board, which has set requirements for this mandatory intervention at continuing intervals of 30,000 flight cycles or 12 calendar years.
Will Dew, Managing Director Commercial at Liebherr Aerospace Saline, Inc. commented: “We are very pleased to welcome Horizon Air into our Liebherr network landing gear overhaul full support portfolio. Horizons advance planning for removals two years distant has secured both the overhaul slots and the necessary exchange support assets to ensure timely and systematic cycling”.
In preparation for the extensive E175 overhaul campaign in the Americas region, Liebherr has focused high energy and resources towards a structural transformation of its landing gear MRO activities over the past three years. “We will continue to adapt lean processes for repair chain efficiency, first pass yield, and supply chain redundancy whilst maintaining adherence to the highest quality standards” concluded Will Dew.
The complete landing gear system for the Embraer E1 generation of E-Jets was developed and is manufactured by Liebherr-Aerospace Lindenberg GmbH (Germany), Liebherr’s center of competence for flight control and landing gear systems.
From the entry into service in 2004, the Embraer 170/175-E1 family aircraft have proven highly successful with 1,000 orders and current production backlog of 208 aircraft.
