ED Decision 2025/007/R
SAFETY RISK MITIGATION MEASURES FOR CHANGES IN THE AIRCRAFT’S CENTRE OF GRAVITY DURING PASSENGER BOARDING OR DISEMBARKATION
Changes in the aircraft’s centre of gravity during boarding/disembarkation may lead to the aircraft’s nose lifting up, causing issues and potential injuries to passengers/aircrew, damage to the GSE docked to the aircraft or aircraft tail tipping.
(a) The operational procedure for passenger boarding and disembarkation should cover the following key risk areas, as a minimum:
(1) aircraft damage by the GSE docked to the aircraft (PBBs, passenger stairs);
(2) aircraft tail tipping;
(3) movement of the aircraft’s centre of gravity too far aft;
(4) passengers and aircrew getting injured due to aircraft pitch angle changes;
(5) damage to the GSE docked to the aircraft.
(b) The operational procedure for passenger boarding and disembarkation should consider synchronising cargo loading/unloading with passenger boarding/disembarkation to maintain a forward centre of gravity.
(c) The turnaround coordinator, the person monitoring passenger boarding and disembarkation, and the aircraft loading personnel should be trained to recognise early signs of the aircraft’s centre of gravity moving too far aft and take the required corrective actions.
