This report documents the number and types of safety occurrences
involving loading of high capacity aircraft across a 7-year period
to raise awareness within the aviation industry of the associated
issues. Incorrect loading of containers, pallets or bags into
aircraft can result in them being outside of weight or centre of
gravity operating limits, and this may influence aircraft
controllability. Most high capacity aircraft loading occurrences
are relatively minor, with cargo locks not being raised being the
most common. More serious occurrences have involved shifting cargo
and unlisted cargo being loaded onto aircraft. Aircraft performance
has been affected in a small number of cases, and the result has
been rejected takeoff, extra stabiliser trim, or aircraft control
difficulties.
