Aerostar S.A. has become one of the first independent European MRO organisations to install Split Scimitar Winglets on Boeing 737-800s at its Bacau facility. The installations were carried out on two aircraft belonging to TUIFly Nordic of Sweden – another new customer for Aerostar’s growing commercial aircraft maintenance, repair and overhaul (MRO) business. The first aircraft, a Boeing 737-8K5 (WL), bearing registration SE- RFU, arrived at Bacau in early May for a Base Maintenance Check. At the end of the check, the aircraft – which had already had its wings reinforced ready for the installation – was fitted with the new Split Scimitar Winglets. It was followed by the second aircraft , a Boeing 737-86N (WL), bearing registration SE-RFV, that was subject to a Base Maintenance Check along with the embodiment of the complete Split Scimitar Winglet installation; provisioning (wing structure reinforcement) and installation of the upgraded winglets. The complete installation was carried out in six days and had no impact on the maintenance check downtime.
