On August 5, 1989, Piedmont Airlines was absorbed by USAir (formerly Allegheny Airlines, later US Airways). Many of former Piedmont planes fly for some time with old colors, but with new company name.

The cockpit of this former AeroSur Argentina 727 has been turned into a flight training device for a 737. Its internal components are made of used parts of other 737s. An aviation mechanic and enthusiast purchased the cockpit of this 727 when it was scrapped in Ezeiza on August 2000 and has made it fully functional. Except for movement, this home-simualtor has it all and is even certified to train pilots. Former registrations include: N545PS and N376PA. It was brought to Argentina in 1993 and was parked at Ezeiza from 1994. In 1998 it was painted white. The simulator uses the fake registration N737TD.
