ST Aero has boosted its capabilities in passenger-to-cargo jet conversions – and its role as a supplier of composite panels to Airbus – by taking a majority interest in Dresden, Germany-based EFW – Elbe Flugzeugwerke GmbH.

ST Aero took a 35% stake in EFW in 2012, with Airbus holding the majority interest.

The Singapore company said this month that it had completed its purchase of another 20%, making it a 55% owner and rendering EFW an ST Aero subsidiary.

Airbus Defence and Space holds the remaining 45%.

Plans for the additional investment were announced this past June, when an ST Aero-Airbus-EFW project to convert A320 family passenger jets to cargo jets – the A320/A321P2F – was likewise disclosed.

The A320 work follows a similar collaboration for the A330P2F conversion programs launched in 2013.

EFW employs more than 1,000 people and annual revenues of better than 200 million euros (US$225 million).

The Dresden entity is the exclusive supplier of composite flat panels to Airbus for all Airbus aircraft and “will serve as ST Aerospace’s centrer for passenger-to-freighter conversions, aircraft maintenance, repair and overhaul (MRO), as well as engineering services in Europe, leveraging ST Aerospace’s global network, track record and expertise in aircraft MRO and engineering,” ST Aero said.
