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 Norwegian air accident investigation bureau (AIBN) has made progress in explaining the <a href="https://www.ainonline.com/aviation-news/aerospace/2016-05-24/no-answers-yet-after-norwegian-h225-accident">April 29 crash of a CHC-operated Airbus H225</a>, and from this juncture the agency is&nbsp;considering only three possibilities.&nbsp;In an interim report released late last week, the bureau cites the three possible causes for in-flight separation of the main rotor as failure of the epicyclic module, a lift-strut attachment or the main gearbox conical housing.

 


Meanwhile, Airbus Helicopters said seven potential initial events have been considered. Of these, only one—failure of the lift-strut attachment—is deemed “probable.” The airframer pointed out that analysis of the helicopter’s maintenance history has just started.

 


The recordings on the CVFDR show that everything appeared to be normal until a sudden catastrophic failure developed over the course of one or two seconds, the AIBN said. The CVFDR recordings ended abruptly at the same time. However, the French BEA succeeded in downloading information from the flight data monitoring system&nbsp;that extends 13 seconds beyond the CVFDR data.

 


Detailed metallurgical examinations have been under way since May 19 but are said to be still at an early stage.
