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.

The Eurocopter EC135 light twin helicopter is facing more trouble after the EASA issued an emergency airworthiness directive on December 19 referring to a manufacturer alert service bulletin that requires a one-time check of fuel probes and, possibly, cleaning and replacement. The issue, discovered by Bond Air Services, appears to be that the probes are indicating a fuel level higher than actual. Investigations showed that the incorrect signals that the probes transmit to the indicator may also inhibit the amber “fuel caution” light. Tests confirmed the problem starts with water contamination. As of December 23, 264 sensors had been tested. Of those, 12 needed to be cleaned but were fully functional afterward, while two failed and needed to be replaced. Meanwhile, the “low fuel” warning system is independent and remains reliable, Eurocopter said. Pilots should thus strictly heed the red “low fuel” light, regardless of the fuel quantity indication. The company has also issued a safety information notice for EC145 operators, as the latter helicopter uses similar fuel sensors.
