Tempe, Arizona, — Landmark Aviation, a Bombardier Business Aircraft Authorized Service Facility (ASF), today announced it is authorized to perform retrofit installations of the Honeywell GTCP36-150 (CL) auxiliary power unit (APU) on Bombardier Challenger 604 and Challenger 601 widebody business jets.
Landmark’s maintenance facilities at Los Angeles International Airport (LAX) and Bush Field (AGS) at Augusta, Ga., will provide the installations.
“The new capability is an addition to our strong legacy of APU service. We have provided APU hot section inspection and service at our operations for more than 15 years,” said Bob Sundin, Landmark Vice President, Airframe Operations. “Challenger aircraft operators now have an option to complete this retrofit together with scheduled engine or airframe maintenance at Landmark’s full service operations at Los Angeles and Augusta.”
Landmark Aviation has four major MRO centers – Los Angeles, Augusta, Houston and Springfield. Each site is an authorized Honeywell APU hot section inspection facility.
The company’s Augusta service center is a full service APU repair center with hot section, repair and overhaul capability, including a test cell on-site for the Honeywell GTCP36-100 and 150 APU models. Landmark also maintains a large pool of 36-100 and 36-150 APU rentals and spares.
Honeywell’s new GTCP36-150 (CL) APU has higher temperature margins, resulting in an increased hot section inspection interval of 2,400 hours, increased reliability and lower maintenance costs. Among the numerous improvements of the new APU over the original GTCP36-100 are an improved maintenance program with 500-hour intervals, up from 400 hours, plus enhanced operational limitations for in-flight start capabilities, bleed air extraction and APU generator usage conditions.
The new APU has been incorporated as standard equipment on the Challenger 604 aircraft since the third quarter of calendar year 2005 and is also standard on the new generation Challenger 605 jet, scheduled to enter service in the third quarter of calendar year 2007.
