Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During cruise flight, approximately one hour after departure, the captain complained of possible indigestion. A few hours later, the captain complained of tingling in his fingers and numbness in his shoulder. Another captain was on board and was asked to sit in the left seat. The flight was diverted and was landed without incident. One week after the incident, the captain underwent coronary by-pass surgery.
