it looks like the passenger door is recessed rather than being flush with the fuselage. With the plane under its own power I assume it's just landed or about to depart. So is there something about Tu134 doors that "unseat" on the ground??

Quoting Oly720man (Thread starter):

I'd say it is probably because there is little or no differential pressure whilst the aircraft is on the ground. Perhaps the TU-134, or this example alone has a bulky door seal? I imagine the door would press out until it reaches the stops and become flush with the surrounding fuselage as differential pressure increases as altitude is gained.

Looks more likely that the Door is rigged more inwards.After pressurisation it would move outwards to an extend.

IIRC the TU 134 door opens inwards, not inwards before swinging out like on a normal a/c it swings in .

Pressurisation loads would move it outwards to contact the Fuselage stops by the door pins to transfer pressurisation loads to the structure.

Thanks for the answers.

Could it be then that the plane had just landed and the fuselage pressure was a bit below atmospheric (having not equalised yet) and the door had been forced inwards?

Yes it looks like there isn't enough pressure differential. The plane is taxiing to takeoff actually.
