Independent Representation in the Most Contested Events in Aviation
Airline lease returns are among the most technically complex and financially consequential events in commercial aviation. Millions of dollars can turn on whether an aircraft is returned in agreed condition — and whether the records correctly reflect its maintenance status. IAS provides independent technical representation for both lessors and lessees, ensuring the process is managed rigorously and transparently.
With decades of hands-on experience in aircraft technical evaluation and records review, IAS brings the same depth of expertise to lease management that we apply to VVIP aircraft acquisitions and completions. We know what to look for, what to negotiate, and how to protect our clients at every stage.
