Airbus has reached the first major milestone in its production ramp-up activity for its single-aisle fleet, with output now at 38 aircraft per month.

The aircraft maker has already announced plans to boost production to 42 aircraft per month in the fourth quarter of next year to meet strong demand, and is considering a further production rate increase to 44 units per month. One of the biggest concerns is whether the aircraft maker’s supply chain can support the 44 aircraft per month output level, given other manufacturers are also raising rates.

The 38 aircraft per month production rate sees Airbus’s Hamburg facility assemble 20.5 aircraft per month, the Toulouse site processing 14.5 A320 family aircraft, and the Tianjin facility in China with output at three aircraft per month. The next milestone for Airbus should come in the first quarter of 2012, when output should reach 40 aircraft per month.

Airbus’ backlog for single-aisle aircraft now stands at about 3,000 aircraft.
