On April 24, 1990, a Boeing 707-321B (registration CCCYB) operated by Operada EN Arrend. Por Ladeco was involved in an aviation accident near Miami, FL. Investigators recorded the probable cause as: The aft CG limit had been exceeded. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During takeoff, the aircraft's nose lifted and it turned left, rolling about 50 feet before coming to rest in dirt. Investigation found aft CG limit exceeded.
Incident Description
During the takeoff roll, the captain applied takeoff EPR. Immediately, the nose of the aircraft lifted off the ground, and the aircraft began a 90-degree turn to the left of the runway centerline. The copilot applied full forward yoke and assisted the captain with braking, power lever reduction, and fuel reduction. Despite these actions, the aircraft continued its roll for approximately 50 feet before the nose lowered and the aircraft came to rest in the dirt adjacent to the runway.
Investigation Findings
Post‑investigation examination revealed that the aircraft’s aft center of gravity (CG) limit had been exceeded at the time of the incident.
