Narrative:
We had just leveled off at FL290 -- cabin altitude reached 10000 ft MSL with a slow 500 FPM cabin climb, an emergency descent was initiated and an emergency was declared -- diverted to abq (nearest suitable) to an overweight landing. No crew or passenger injuries. A postflt walkaround discovered that the forward cargo netting was not secured and some straps and fasteners were caught in the door seal resulting in a gap and subsequent loss of cabin air and pressurization -- door was locked securely. Straps and fasteners appeared worn, any worn or difficult to fasten netting must be replaced. In addition to checking proper door lock and visual inspection of the seal must be made. The straps and fasteners were quite visible even though the door was closed properly.

Title: CABIN PRESSURIZATION LOSS EXPERIENCED AT FL290. THE ACR FLC INITIATED AN EMER DSCNT AND DECLARED AN EMER. FLT DIVERTED. OVERWT LNDG.
Narrative: WE HAD JUST LEVELED OFF AT FL290 -- CABIN ALT REACHED 10000 FT MSL WITH A SLOW 500 FPM CABIN CLB, AN EMER DSCNT WAS INITIATED AND AN EMER WAS DECLARED -- DIVERTED TO ABQ (NEAREST SUITABLE) TO AN OVERWT LNDG. NO CREW OR PAX INJURIES. A POSTFLT WALKAROUND DISCOVERED THAT THE FORWARD CARGO NETTING WAS NOT SECURED AND SOME STRAPS AND FASTENERS WERE CAUGHT IN THE DOOR SEAL RESULTING IN A GAP AND SUBSEQUENT LOSS OF CABIN AIR AND PRESSURIZATION -- DOOR WAS LOCKED SECURELY. STRAPS AND FASTENERS APPEARED WORN, ANY WORN OR DIFFICULT TO FASTEN NETTING MUST BE REPLACED. IN ADDITION TO CHKING PROPER DOOR LOCK AND VISUAL INSPECTION OF THE SEAL MUST BE MADE. THE STRAPS AND FASTENERS WERE QUITE VISIBLE EVEN THOUGH THE DOOR WAS CLOSED PROPERLY.
