AlliedSignal has signed a multi-year APU procurement and maintenance service agreement valued at $5 million with China's Yunnan Airlines.

Under the agreement, Yunnan will use AlliedSignal's 85-129 series APUs exclusively on its fleet, as well as utilising TAECO, the company's in-China repair and overhaul base, for repair and overhaul.

The airline's growing fleet of B-737 'classic' aircraft is expected to increase to 14 in 1998.

The 85-series APU routinely gives operators 8,000 hours (or nearly four years) of average airline service operation between unscheduled removals, providing both pneumatic and electrical power for the aircraft while on the ground or in flight.
