But then during OE, the check airman said we don't do that at a hub since MX comes out and doesn't want to power up every plane just to see the oil level. Then there was an update on the fleet that even removed the 2 hour rule and just said to pull them if the plane will be sitting for a long time.
A few years go by, a few more fleets, and now I'm on the 737 and I see it every trip. What's really strange is I see crews go through the entire shutdown checklist in the middle of the day in base AND pull the breakers. Why? Can anyone find an actual reference to where we need to be doing this? And what are other fleets doing?
I've been on the fleet for 8ish years now..and I've noticed that most don't pull them in a hub, but pretty much everyone does in an outstation especially if they shut the airplane all the way down.
The way the book is written it says something like if the plane is going to sit for 2 hours or more then you should do a full securing checklist. But even LCAs seem to say not to do that in a mx base. I still do a full securing checklist at night even in a mx base unless I talk to mx. But it's really not clear what we're supposed to do because LCAs say one thing and the book says another.
