## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) ON MAY 17, 2004, HOWARD KEITH NELSON WAS PILOT IN COMMAND OF N52CK, A CESSNA S550 CITATION JET ENROUTE FROM ROXBORO, N.C. (TDF) TO PEACHTREE-DEKALB, GEORGIA (PDK) AT FLIGHT LEVEL 280 AND 20 MILES NORTH OF CHARLOTTE, EXPERIENCED DECOMPRESSION AND FOG IN COCKPIT. THE PILOT DECLARED AN EMERGENCY AND DESCENDED TO 10,000 FEET MSL PER THE CESSNA EMERGENCY CHECKLIST. DURING THE EMERGENCY DESCENT LOSS OF SEPARATION OCCURRED WITH AAL 1741, T/MD82/G AT FLIGHT LEVEL 270 ENROUTE FROM RALEIGH-DURHAM, N.C. (RDU) TO DALLAS, TEXAS (DFW). CLOSEST PROXIMITY WAS 3.7 MILES AND 400 FEET. MR. NELSON WAS INTERVIEWED BY THE CLT FSDO AND EMERGENCY REVIEWED. THE CAUSE OF THE PRESSURIZATION PROBLEM WAS A SEPARATED COUPLING ON THE AIR CYCLE MACHINE WHICH WAS DISCOVERED BY MAINTENANCE. THIS INCIDENT WAS CLOSED WITHOUT FURTHER ACTION TAKEN.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
