Thierry Dubois is a freelance writer specializing in helicopters, business aviation and aerospace technology. He earned a degree in fluid dynamics from an engineering school in Toulouse, France in the mid-1990s. At an unexpected crossroads, he found his first job in journalism. In 1997, he started working for French aerospace weekly Air &amp; Cosmos in Paris. This lasted until 2000, when he moved south to Lyons. He then became a freelancer, working for various aerospace publications and has been part of the AIN team since late 2000. In addition to writing about business aviation, Thierry shares responsibility for the rotorcraft section. He also is a regular on-site writer for AIN’s daily editions at international airshows such as the Paris, Farnborough, Dubai and Singapore shows, as well as at EBACE in Geneva.
In 2007, he won the Honeywell award for “Best systems or technology submission” at the Aerospace journalist of the year awards. In 2013, he won an Aerospace Media Award for the "Best Safety, Training &amp; Simulation Submission."
In other activities, Thierry moderates international conferences on aviation technology topics. Thierry is married and has three children, who seem to begin enjoying the mountains–as their parents do.

Bristow officials are confident an “interim way to safely fly” Eurocopter EC225s will be found late this spring or early this summer. In a recent fiscal third-quarter earnings conference call, top executives at the helicopter operator said such an interim fix could be tighter oversight of Hums parameters, thus confirming what <a href="http://www.ainonline.com/aviation-news/ainalerts/2013-01-29/eurocopter-sees-ec225-solution-april">Eurocopter’s CEO hinted late last month</a>. A shaft redesign, if needed, would take about a year-and-a-half, Bristow officials estimate.


In the wake of several ditchings stemming from false alarms of gearbox lubrication system failures, Bristow has suspended operations of 16 EC225s–12 in the UK, three in Australia and one in Norway. Other major offshore operators are also feeling the effects of the grounding–CHC has 30 EC225s out of service, and Bond would not give a precise number but AIN understands it is in the single digits.


Bristow estimates that, while 17 EC225s are still flying in China and Vietnam, about 80 aircraft have been suspended from flying worldwide. Among other mitigation measures for offshore platform crew changes, oil companies are sharing available space in helicopters, according to a union source and a representative of an oil company.
