[H]ow long before Part 135 comes into being[?]
Mr Skidmore’s predecessor’s predecessor, Mr Byron, gave this answer in February 2005:
We have an action item to develop a plan to forward to the minister about when we plan to have them to the minister, and I assume that plan would be done in the next couple of months. I would be hopeful that it would not be long after early 2006 that most of the draft rules are delivered to the minister.
That statement was made
over ten years ago.
Mr Skidmore’s predecessor, Mr McCormick, gave this answer in the "Aviation Safety Yearbook 2013":
[O]ur current schedule will see the remaining rules completed by the end of next year.
By my calculations, the next year after 2013 was 2014, and 2014 has ended.
I used to care what these people said.
Trust me: Ignore them.
