An improperly balanced aircraft can completely lose aerodynamic control and crash, regardless of pilot skill. When the center of gravity (CG) moves outside allowable design limits, the physical forces required to maintain stable flight exceed the mechanical capability of the control surfaces.
Placing too much weight in the tail makes the aircraft tail-heavy. This creates extreme longitudinal instability, pitching the nose upward into an unrecoverable aerodynamic stall or spin.
A Douglas DC-8 cargo flight crashed seconds after takeoff in Miami because the freight was loaded incorrectly toward the rear. The severe aft center of gravity caused an immediate, violent nose-up pitch. The pilots pushed the control columns completely forward, but the elevators could not counter the tail-heavy leverage, leading to a fatal stall.
The aircraft involved in the accident was a 29-year-old McDonnell Douglas DC-8-61, manufacturer serial number 45942, line number 349, registration N27UA, operated by Fine Air, with 48,825 total airframe hours and 41,688 cycles
The NTSB released the accident report on June 16, 1998. The "probable cause" reads:
The National Transportation Safety Board determines that the probable cause of the accident, which resulted from the airplane being misloaded to produce a more aft center of gravity and a correspondingly incorrect stabilizer trim setting that precipitated an extreme pitch-up at rotation, was (1) the failure of Fine Air to exercise operational control over the cargo loading process; and (2) the failure of Aeromar to load the airplane as specified by Fine Air. Contributing to the accident was the failure of the Federal Aviation Administration (FAA) to adequately monitor Fine Air's operational control responsibilities for cargo loading and the failure of the FAA to ensure that known cargo-related deficiencies were corrected at Fine Air
