How should LMCs be communicated to the commander?

LMCs should be communicated to the commander in writing (e.g., on an LMC slip or loadsheet) or verbally, and if verbal, they should be recorded in the flight file.

From which date is the requirement for LMCs applicable according to ED Decision 2025/008/R?

The requirement is applicable from 27 March 2028.

GM1 CAT.POL.MAB.105(d) Mass and balance data and documentation

Q: What are last-minute changes (LMCs) in the context of mass and balance documentation?

LMCs are late adjustments 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, reflecting any change made to aircraft loading since the initial issue.

Q: When must the final mass and balance and load control documentation be updated?

The final mass and balance and load control documentation must reflect any change that has been made to aircraft loading since the initial issue of the documents, before departure.

Q: List the minimum information that must be contained in an LMC.

LMCs must contain at 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), and (6) the total mass and index change.

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.
