Air Doc Services (ADS) has completed its 75th business aircraft pre-purchase inspection concurrently with the Swiss company’s third anniversary. Based in Basel, the technical services firm supports business aircraft owners, operators, and buyers with a range of services, including pre-purchase inspections, registration change support, records digitization, and technical oversight.
Founded in 2022 by Mary Preud’homme and Rogerio Machado, ADS brings more than five decades of combined aviation experience. Preud’homme, a former airline pilot and pre-purchase inspection engineer, previously served as director of business development at Paramount Global Ferry Services. Machado, a licensed aircraft engineer and continuing airworthiness management organization post holder, held leadership and maintenance roles at NetJets Europe and Jet Aviation.
Working alongside technical records administrator Alexandra Machado, the ADS team has completed 75 inspections in just three years, averaging one pre-purchase inspection every two weeks.
“We are proud to have reached these twin milestones,” said Preud’homme. “Our vision has been to deliver a flexible and expertise-based approach to business aviation.” Machado added that ADS aims to provide highly personalized client support through the entire life cycle of an aircraft asset.
