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.

Eurocopter has issued a statement that essentially clears operator Bond Offshore Helicopters in the ditching of an EC225 medium twin in the North Sea last month. “At this stage of the investigation, neither procedure failure nor human error on the operator’s side have been identified as a potential contributor to the cause of the incident,” the manufacturer said.


Just weeks after having questioned the crew’s decision to ditch following dual loss-of-lubrication alarms, the manufacturer is now praising the pilots’ “professionalism and skill.” Eurocopter says it expects “no redesign or grounding requirement” from civil aviation authorities as a result of the incident.


All 14 aboard survived the ditching, which sparked an emergency Airworthiness Directive and Bond’s decision to suspend some flights. Since the ditching, only EC225s equipped with health and usage monitoring systems (Hums) are authorized to perform IFR flights over water. The UK’s Air Accidents Investigation Branch (AAIB) probe is focusing on the failures of both the primary and backup main-gearbox lubrication systems.
