Sustaining the life of aircraft engines ® At AAR, Doing It Right means positively impacting the aviation ecosystem and supporting the sustainability practices of our commercial airline and government customers worldwide. We continually enhance our capabilities to support innovative technologies that minimize our industry’s impact on the planet and promote quality and safety. For example, in 2019, as part of our strategy to sustain the life of engines, we were awarded a seven-year contract with the Danish Defense Acquisition and Logistics Organisation (DALO). The contract involves maintenance, repair and overhaul of Pratt & Whitney F100-220 engine components on the General Dynamics F-16 so they can continue serving the Royal Danish Air Force (RDAF) for years to come. In addition, as part of our efforts to minimize waste, certain of our facilities have implemented comprehensive waste minimization plans. These plans focus on recycling more materials whenever possible, including used oils, off-spec fuels and other hydrocarbons, as well as cardboard. We are also focused on complying with evolving waste handling regulations and requirements, including with respect to chemicals. The treatment and disposal of hazardous waste is a critical component of our environmental compliance. 16
