Not as such.
You need someone who knows when and how to use lawyers properly. Often that's a skill that comes from experience as a lawyer, but it's certainly not the only way to attain the necessary skill.
You need someone who also knows when and how to use the expertise of pilots properly, and the expertise of LAMEs properly, and the expertise aeronautical engineers properly, and the expertise of airline operators properly...
You need someone who can keep all of the experts under control and focussed on what they are paid to do rather than push barrows in their area of expertise.
Experts in the subject matter being regulated very rarely have the necessary detachment to manage regulatory authorities properly.
