Hey PIT Dude,

Yes log the time, and yes talk about it in the interview. As said before, be sure you can discuss technical basics about the good ol' Navajo. If the leg was 91, you can certainly log part 91 PIC if you are the sole manipulator of the controls (you have your multi cert, right?). This should be fine for most regional airlines.

For applying to a Major airline your turbine PIC must be "by the book", and it is a different set of rules and conditions from what you are operating under. For a regional, you have proven basic competency, character, and personality to have someone "give" you the shot to fly a somewhat bigger airplane around, and to be willing to spend time with you up front. This actually will mean something to most regional recruiters.
