New language is found in HR 5900, which was passed yesterday:

Read The Bill: H.R. 5900 - GovTrack.us

(1) NUMBERS OF FLIGHT HOURS- The total flight hours required by the Administrator under subsection (b)(1) shall be at least 1,500 flight hours.

(f) Deadline- Not later than 36 months after the date of enactment of this Act, the Administrator shall issue a final rule under subsection (a).

So, yes, it's still 3 years to implement from date of enactment (President's signature).
