It is foolhardy to draw hasty conclusions about accidents. The investigation into the cause of the Asiana 214 Boeing 777-200ER crash at San Francisco International Airport on July 6 is still in its early stages. While it is not clear exactly how crew performance figured into the accident that claimed three lives, we believe that there is no excuse for landing short on a calm, clear day in a fully functioning jetliner.

Even as they develop engines promising 15-16% lower fuel burn on the latest narrowbodies, manufacturers are looking toward the 25-30% fuel-consumption reductions expected to be required by the mid-2020s to help keep airlines ahead of oil prices and emissions targets.

Pratt & Whitney Canada took the first steps toward developing what would become the world's most popular turbine in 1956, when the company's engineering manager, Dick Guthrie, was told to hire a team of gas turbine engineers to lead the development of new generation of engines.

While most engine makers generally support a few hundred users of their products, Pratt & Whitney Canada (P&WC) supports the maintenance needs of a hugely diverse set of over 10,000 operators, 90% of whom have only one or two aircraft.

In the wake of June's Paris air show, both Airbus and Boeing issued victory statements detailing orders, options, commitments and letters of intent reportedly signed during the five-day event. Both rivals claimed they achieved or surpassed their most optimistic sales predictions, disseminating robust releases to the media. And, once more, the press corps—in most cases without the required restraint—agreed to the rules of the game, although that was largely meaningless.

It has been a 10-month-long wait, but operators should soon be returning their workhorse Eurocopter EC225s to the skies.

In the North Sea, the Eurocopter EC225 has been a workhorse, plying routes between bases in Norway and Scotland oil and gas platforms. But for 10 months, the helicopter has been missing from such operations, grounded as engineers searched for the root cause of the failure in its bevel gear vertical shaft. For the major operators in the North Sea region such as Bond Offshore Helicopters, Bristow Helicopters and CHC Scotia, the loss of the type from their fleets had a dramatic impact on their capacity to fly for customers.
