Incident Overview
On an instrument landing system (ILS) approach to runway 22L, Delta Air Lines Flight 752, a Boeing 767, encountered an uncommanded go-around while near the outer marker. The aircraft drifted to the right of the localizer for over one minute. At approximately 1,000 feet above ground level, the crew sighted runway 22R to the left and executed a normal landing on that runway. Runway 22R was offset 1,500 feet to the right of runway 22L.
Sequence of Events
A preceding Boeing 727 had been cleared to cross the right runway. The air traffic controller failed to observe the progress of the Boeing 767 after it passed the outer marker. The crew of the Boeing 727 saw the landing lights of the Boeing 767 as it approached runway 22R and notified the tower that they would hold short of the runway.
Findings
The uncommanded go-around malfunction was traced to a faulty wiring harness in the throttle quadrant. The captain of the Delta flight had a reputation for dominant behavior that tended to suppress others in the cockpit. Additionally, the airline's operations manual provided minimal direction concerning missed approaches.
