Narrative:

Climbing through FL240 for FL260 we experienced a rapid/explosive depressurization. We followed operating manual procedures and were unable to control cabin. Initiated rapid descent to 10000 ft. Flight continued to our planned destination at 10000 ft with no complications. Passenger seemed to take everything in stride and were very complimentary of crew response and communications. Complications: flight engineer loudly stated 'I lost the cabin'--this response sent first officer to put on oxygen and start emergency descent. Actually we experienced a rapid depressurization which later reverted to explosive depressurization more effective communication from flight engineer might have been losing pressurization control in automatic/reverting to manual--cabin altitude XXXX! Communications with oxygen masks on was very difficult with hot mikes--sounded like obscene call with the heavy breathing.

Original NASA ASRS Text

Title: LGT EXPERIENCES EXPLOSIVE DEPRESSURIZATION.

Narrative: CLBING THROUGH FL240 FOR FL260 WE EXPERIENCED A RAPID/EXPLOSIVE DEPRESSURIZATION. WE FOLLOWED OPERATING MANUAL PROCS AND WERE UNABLE TO CTL CABIN. INITIATED RAPID DSCNT TO 10000 FT. FLT CONTINUED TO OUR PLANNED DEST AT 10000 FT WITH NO COMPLICATIONS. PAX SEEMED TO TAKE EVERYTHING IN STRIDE AND WERE VERY COMPLIMENTARY OF CREW RESPONSE AND COMS. COMPLICATIONS: FE LOUDLY STATED 'I LOST THE CABIN'--THIS RESPONSE SENT FO TO PUT ON OXYGEN AND START EMER DSCNT. ACTUALLY WE EXPERIENCED A RAPID DEPRESSURIZATION WHICH LATER REVERTED TO EXPLOSIVE DEPRESSURIZATION MORE EFFECTIVE COM FROM FE MIGHT HAVE BEEN LOSING PRESSURIZATION CTL IN AUTO/REVERTING TO MANUAL--CABIN ALT XXXX! COMS WITH OXYGEN MASKS ON WAS VERY DIFFICULT WITH HOT MIKES--SOUNDED LIKE OBSCENE CALL WITH THE HVY BREATHING.
