PEMCO World Air Services (PEMCO), a leading global MRO and aircraft conversion provider, has announced an additional five-aircraft 737 PTF program with China’s postal service commencing September 2013. This deal follows the recent redelivery of its tenth freighter, an 11-position High Yield 737-400F, for Beijing-based China Postal Airlines (CPA). By this time next year, China Postal’s fleet will include 15 PEMCO-modified 737-300F & 737-400F aircraft, reaffirming their commitment to the highly successful partnership with PEMCO. The first two 737-300 aircraft are scheduled for induction this month, with the remaining three being converted in 2014. The conversions will be performed at STAECO’s Jinan Shandong facility, PEMCO’s partner on over 40 Boeing 737-300 & -400 freighter modification projects.
