Ameco Beijing, a joint venture between Air China and Lufthansa, has won engine overhaul work from Air Finland and Kazakhstan's Air Astana.
The two long-term contracts are for overhaul work on the Rolls-Royce RB211 engines, which are used to power Air Finland and Air Astana's fleet of Boeing 757s, says the Beijing-based maintenance, repair and overhaul firm.
Two engines from Air Finland are already in Ameco Beijing's workshop, and the first of Air Astana's engines are due to come in February, it says.
Air Finland has two 757s and Air Astana has four 757s. according to Flight's ACAS database,
