Ground Op 737 Nose Wheel Well
At the airport today a B737-8 came in, unloaded, loaded, but one thing happened that I don't usually see. One of the ground crew had (not sure whether ear muffs or headphones) muffs on, something dangling from the muffs, and had a cable coming from the nose wheel well, it looked like it was attached to the muffs. The guy went under the well, doing whatever, came out, dragged the long wire out and stood a couple of meters in front of the aircraft, before going back under the well. He did this quite a few times. What was happening?

I’m guessing that’s the flight/service interphone that they were using to talk to whoever is in the flightdeck. At my airline it’s inside the external power panel on the right side by the nose.
Nothing better than the sound of a 77W GE90-115B on engine start.

It is the ground engineer connecting his headset. The connection may be on the nose gear leg or on the external power panel. He can then talk to the cockpit via interphone. This is often wireless nowadays so you won't see an actual cable.
After pushback and engine start, the pilot flying will say "Start is complete. Cleared to disconnect." This is the signal that we no longer need any ground services, so the engineer can disconnect his headset and walk away from the aircraft.

What would they be talking over? Also, why would the guy have to come back out in front of the aircraft? Just thinking maybe is it just a psychological type of thing to see the person the pilots are talking to or....?
Re: Ground Op 737 Nose Wheel Well
Maybe he had to observe something for whom ever was is the flight deck. Say it is a mechanic upstairs doing the standby rudder check. Someone should be outside to make sure the rudder is clear of obstructions before the test is begun. Same goes with lowering the flaps. Hard to tell if they are clear if you are standing in the nose wheel well. Engine start is another thing. Make sure the engine is clear before start.

The jack for the headset is not in the wheel well on a Max. It is in the same location as all other 737s on the right side of the fuselage next to the ground power connection socket. If a wireless device is used, the receiver box will still plug into the same location.
All I can think of was that he was inserting a steering lockout pin and the pins are retained to the pushback by that cable. My airline does not retain pins in that manner but clearly this was not my airline.

Sometimes dogs that get out of their kennels in the cargo hold can get into the nose wheel well on the 737.
Normal procedure for ground ops with the 737.

Absolutely no. There is no way to get from the fwd bin to the wheel well. Directly behind the wheel well is the Electronics bay. No doors between it and the wheel well or the cargo bin. Solid Aluminum pressurized wall from well to E/E bay. Gill liner fire block wall from Bin to E/E.
