Remarks (Bemerkungen)
The ERJ 135 is a direct derivative of the ERJ 145, featuring a shorter fuselage (- 3,5 metres) but otherwise maintaining a 94 per cent part number commonality and no system architecture changes to ensure maximum benefit of mixed fleet operations.
The ERJ 135 was announced on September 16, 1997. Roll-out of the first prototype - modified from the first EMB-145 - took place on May 12, 1998. First flight was achieved on July 4, 1998, some two weeks ahead of schedule. After two flights and a total of five hours, test pilots Luiz Alberto Madureira da Silva and Clodoaldo Gualda Moreno had explored the full operational envelope of the ERJ 135. All flap and gear configurations were tested. On both flights, the aircraft was flown at its maximum take-off weight.
A second prototype took to the air in October. Certification in Brazil was achived in June 1999. Deliveries commenced on 23 July 1999 to Continental Express. By the end of 2006 all 108 ordered aircraft had been delivered. Since then the ERJ 135 is only produced in form of the corporate Legacy version.
