737ng Cargo Door
HELLO ALL,
on the 737 qrh about cargo door (aft or fwd), there are two options. if tere is no pressurization problem than continue normal flt, if there is pressurization problem, acft should be decended and the crew have to decrease the diff press. to zero.
the question is what is the reason for zero diff press.?

Just thinking aloud here,
maybe the NNCL assumes that if pressurisation is not normal then there is a potential structural problem with the door and therefore reducing the diff will reduce stress on the door and fuselage etc?
As its a plug door, if there was no structural problem then pressurisation should be normal?
As I said, just thinking aloud.

In our OM part B it says the zero diff press is to protect the cabin floor. When the door would completely fail with the aircraft still pressurized this would cause such a rush of air that it might let the cabin floor collapse.
This situation has happened before on a DC 10 of Turkish airlines:
