• ED Decision 2025/008/R found in: Air Operations Revision 24 Part-ARO Part-ORO Part-CAT Part-SPA Part-NCC Part-NCO Part-SPO (Mar 2026)

##### GM1 CAT.POL.MAB.105(d) Mass and balance data and documentation *ED Decision 2025/008/R* **LAST-MINUTE CHANGES** (a) Mass and balance and load control documentation is expected to reflect the actual loaded state of the aircraft before departure. The final mass and balance and load control documentation needs to reflect any change that has been made to aircraft loading since the initial issue of the documents. These late adjustments are called last-minute changes (LMCs). (b) LMCs are used to make late updates to the mass and balance and load control documentation without requiring the preparation of a new issue of the document. (c) If in any doubt about the limitations of the aircraft, the operator should ensure that the mass and balance and load control documents are reissued. LMCs contain the following information at a minimum: (1) the load to be changed (baggage, passengers, cargo, etc.), (2) the mass of the load to be changed, (3) the location of the load to be changed (cabin/bay area, cargo compartment, etc.), (4) the nature of the change (enter ‘+’ for an increase or ‘–’ for a decrease, as appropriate). (5) the intended location of the load (if remaining on board), (6) the total mass and index change. (d) Aircraft flight envelopes may be more restrictive at lower weights. Changes in loading applied to a lighter-loaded aircraft will affect its centre of gravity more, so LMCs should be checked carefully. (e) With an increasing number of pieces of hand baggage, some of those pieces may need to be relocated into a cargo compartment. In such cases, the calculations should be completed as part of the LMCs. (f) LMCs should be communicated to the commander in writing; for example, on an LMC slip or loadsheet, or verbally, which should be recorded in the flight file. *[applicable from 27 March 2028 — ED Decision 2025/008/R]*
