but every C152 I've flown has a step on the strut so you can visually check the fuel, and indeed the top of the wings. Is this not the case on all 152's?
I don't think it is universal; I used to fly several C152s in my PPL training and none of them had that step. I never saw anyone use a ladder with them either; if the tank is fairly full you can reach up and poke a finger into the tank and if the end of it gets wet then you have a nearly full tank.
