Air Doc Services (ADS), based in Basel, Switzerland, has reached a major milestone with the completion of its 75th pre-purchase inspection (PPI) since its founding in 2022.
Created by Mary Preud’homme and Rogerio Machado, both seasoned aviation professionals with over 50 years of combined experience, ADS specializes in providing tailored technical services to business aircraft owners, operators, and buyers worldwide.
Mary, a former airline pilot and PPI engineer with extensive CAMO expertise, brings unique insight from the cockpit, while Rogerio contributes more than three decades of engineering and MRO leadership, including senior roles at Jet Aviation and NetJets Europe. Together with Technical Records Administrator Alexandra Machado, they have built a nimble, highly skilled team able to deliver precise evaluations across all conditions.
In just three years, ADS has achieved a rhythm of one PPI every 14 days, reflecting both its technical depth and its customer-centric approach. Beyond PPIs, the company also provides aircraft registration change support, records digitization, technical oversight, and audits—further reinforcing its role as a trusted partner in safeguarding aircraft assets.
