Report

Investigation Summary

The incident occurred during the taxi phase as the flight prepared for departure to Philadelphia. The Captain had successfully taxied the Boeing 757 to the runway hold line and engaged the parking brakes while awaiting final takeoff clearance. While in this stationary position, the First Officer observed the Captain slump over and heard him making a gurgling noise, indicating immediate medical distress. A physician traveling as a passenger and a member of the cabin crew performed cardiopulmonary resuscitation (CPR) on the flight deck. The aircraft remained safely on the ground throughout the medical emergency. Toxicology tests were performed as part of the investigation, and the NTSB determined the cause of death was a cardiovascular incapacitation.

Final Conclusions

The National Transportation Safety Board determined the probable cause of the incident to be a fatal heart attack suffered by the Captain. The investigation noted the Captain held a valid Class 1 medical certificate with waivers/limitations at the time of the event.
