Emirates has contracted four international MRO providers to install the permanent full-life wing-rib fix on its Airbus A380 fleet until the end of 2014.
The Dubai-based carrier selected Ameco Beijing - a maintenance joint venture between Air China and Lufthansa - as well as Abu Dhabi Aircraft Technologies (ADAT), France's Sabena Technics and EADS subsidiary Elbe Flugzeugwerke (EFW) to modify its aircraft.
However, Iain Lachlan, senior vice-president for Emirates' engineering division, says that EFW will complete the work in Abu Dhabi instead of its own facility in Germany.
The Dresden-based company could not be immediately reached to verify how it intends to undertake the work in the UAE.
Emirates' fleet modification programme to fix the cracks affecting wing-rib brackets on its A380s will begin in April. The work is due to be completed in early December 2014, says Lachlan.
According to Flightglobal's Ascend Online database, Emirates currently operates 31 A380s, with another 59 on order.
Ameco will install the wing-fix on nine in-service aircraft.
