Narrative:

Flight was normal until beginning of descent where we lost the right bleed air; shortly followed by a main cargo door open light and oral warnings; where we could hear air pressurization escaping; we advised ZZZ CTAF and had it relayed to ZZZ1 radio; at that point ZZZ reported visibility at 2 miles; the approach required 3; [and] we continued the approach and had the runway prior to the vdp of 2.8 nm. Landing was uneventful.
