If present trends continue, no airline pilot will fly without a tablet computer; nor will any aircraft mechanic attempt a repair without one. For the pilot, the devices represent the latest evolution in electronic flight bags (EFBs), which first made inroads, nearly two decades ago via the laptop computer. For mechanics, the far less bulky tablets will provide a new measure of mobility, as digital maintenance manuals can be downloaded and taken where the work is being done.

For U.S. Boeing 747-400 operators, going outside the country for heavy airframe maintenance may be the only choice, as North American MRO capacity for the huge aircraft becomes increasingly limited. It's easy to see why, given what has become a relatively small number of aircraft.

For Mexico's airline maintenance, repair and overhaul (MRO) industry, this is a time of change, especially given recent developments at Aeromexico and Mexicana MRO Services, the two heavyweights in airframe third-party maintenance in the country. Aeromexico runs a joint venture with Delta TechOps, and Mexicana MRO Services is operating despite the August 2010 bankruptcy and service suspension of Mexicana Airlines, which once accounted for 60% of its business.
