AAR will be the exclusive manager and single source for repairs and spare parts requirements for Britain's Royal Squadron Fleet squadron of BAe146 and HS125 aircraft.
The three-year agreement includes a one-year renewal option, AAR Corp. said in a release.
The BAe146 and HS125 aircraft, flown by the No. 32 Royal Squadron at air base Northolt are used to transport VIPs, including members of the Royal Family, as well as transporting passengers and freight between Afghanistan and Britain.
"We are excited to grow our existing relationship with the U.K. Ministry of Defense and to provide them with an efficient and cost-effective component repair and procurement program supporting the vital operational roles these aircraft play, said AAR Corp. Aviation Services Group Vice President, Inventory Management and Distribution John Holmes.
"With our experience managing sophisticated supply chains and our history of solid execution, we look forward to a long and mutually beneficial relationship between AAR and the Ministry of Defense."
