Aux États-Unis, cette question relève de la compétence du Bureau de la sécurité des transports. Par exemple, si un pilote perd sa licence pour des raisons médicales, interjette appel auprès du Bureau, récupère sa licence et est ensuite victime d'un accident, il est difficile d'imaginer que le Bureau ne serait pas en conflit d'intérêts dans ce genre d'enquête.
In the United States, that is part of the mandate of the transportation safety board so, for example, if a pilot had a problem with a medical licence and came to the transportation safety board and appealed the loss of his licence, and if that was restored by the board and that individual then went out and subsequently had an accident, it is difficult to imagine that the board would not have a conflict of interest in that kind of investigation.
