AMAC Aerospace welcomed a BBJ due for a Pre-Purchase Inspection (PPI). After the ‘PPI’ was successfully completed, AMAC performed minor modifications on the Boeing B737. The privately-owned aircraft underwent several modifications, including a ‘STC’ (Supplemental Type Certificate). All Part-21 modifications were completed on time and on budget. Finally, the registration was changed and the team re-delivered the aircraft to its new owner.
