A320 family weight and balance
Airbus A320 family weight and balance records review
This review checks that the current weight and balance statement for an Airbus A320 family aircraft reflects every equipment and configuration change since the last weighing. It is run for a lessor, operator, or manager evaluating or transferring an A320 family asset whose cabin or equipment has changed. The work reconciles weighing reports, equipment changes, configuration amendments, and loading documents against the statement in force, following each amendment to a source change. You receive a supported exception list, a source map from statement to amendment, and a closure plan for the specific serial number.
When this review is needed
- A cabin reconfiguration changed the equipment and the weight and balance statement has to catch up.
- A buyer needs the current statement supported by the amendments behind it.
- The last physical weighing is old and the statement rests on a long chain of computed amendments.
- A modification changed empty weight and the statement does not reflect the change.
The problem
An A320 family aircraft's weight and balance statement is built from a weighing plus a running chain of computed amendments for every equipment and configuration change since. Each cabin reconfiguration, galley change, or connectivity installation should add an amendment, and when one is missed the statement drifts from the airframe. On a tail that has been reconfigured several times, the statement can rest on a chain of amendments that does not tie back to a supporting change record.
What gets reviewed
- The current statement reconciled to the last physical weighing report
- Equipment changes traced to the amendments that should record them
- Configuration amendments checked against the modification and equipment records
- The loading documents confirmed consistent with the current statement
- The amendment chain followed from the last weighing to the present
- Empty weight and center of gravity checked for internal consistency across amendments
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Send a representative, redacted record set and we will scope the review.
What gets validated
- The current statement traces to a weighing report or an unbroken amendment chain from one
- Each equipment or configuration change has a matching weight and balance amendment
- Amendments reconcile with the modification and equipment records for the tail
- Empty weight and center of gravity carry forward consistently across the chain
- The loading documents in use match the current statement
Evidence normally required
- The current weight and balance statement for the tail
- The last physical weighing report
- Weight and balance amendments since the weighing
- Equipment change and modification records affecting weight
- The loading documents in use for the aircraft
Common discrepancies
- An equipment change with no weight and balance amendment behind it
- A statement resting on an amendment chain that breaks before the last weighing
- An amendment that does not reconcile with the modification record it should reflect
- Loading documents that lag the current statement
What is at stake
A weight and balance statement that does not reflect the installed equipment misstates empty weight and center of gravity, which a buyer will not accept and an operator cannot load against. A missed amendment breaks the chain from the last weighing forward, and reconstructing the intervening changes is far harder than confirming each one as it happened.

How the work runs
Anchor to the weighing
Establish the last physical weighing the current statement should trace back to.
Follow the amendments
Trace each equipment and configuration change to its weight and balance amendment.
Reconcile to configuration
Match the amendment chain against the modification and equipment records.
List the exceptions
Flag missing amendments and chain breaks and plan reconstruction or re-weighing.
What the buyer receives
- A supported exception list of changes missing an amendment or breaking the chain
- A source map from the current statement back to each amendment and the weighing
- A closure plan to reconstruct the missing amendments or trigger a re-weighing
Who uses the output
- Asset and buyer teams relying on a supported empty weight and center of gravity
- Records teams reconstructing the amendment chain before a transfer
- Continuing-airworthiness teams confirming loading documents match the statement
How the work fits into the transaction or program
The weight and balance review depends on the equipment and modification records being settled, because each amendment should trace to a change recorded there. Its exception list drives reconstruction of the missing amendments or a decision to re-weigh, and the reconciled statement supports the loading basis and the configuration value a transaction rests on.
Aircraft-specific considerations
A320 family aircraft are reconfigured often across their lives, with galley, seat, and connectivity changes that each shift empty weight and center of gravity, so the amendment chain is long and the missed amendment is the recurring failure. A tail that has passed through several cabin layouts is more likely to have a statement that drifted from the airframe, so the review weights the reconciliation toward the reconfiguration events rather than treating the chain as uniform.
Jurisdiction-specific considerations
Weight and balance documentation and re-weighing conventions differ between FAA and EASA operators, so a statement maintained under one system may not carry the amendment detail the other expects. The review notes where the receiving system will require additional supporting amendments or a fresh weighing rather than accepting the chain as assembled.
Regulatory limits
The review confirms the statement is supported by a weighing and a traceable amendment chain. It does not weigh the aircraft, issue a weight and balance approval, or determine that the aircraft may be operated at the recorded values.
What this review does not cover
- Physically weighing the aircraft
- Issuing or approving a weight and balance statement
- Any airworthiness or operational determination on the loading
Specific to this review
- The statement is only as good as the amendment chain, and a single missed amendment detaches it from the airframe.
- Cabin reconfigurations are the most frequent source of an unrecorded weight change on these aircraft.
- A statement resting on an old weighing and a long computed chain is more fragile than one close to a recent re-weighing.

Frequently asked questions
Does the review require a fresh weighing of the aircraft?
Not usually. The review works from the records to confirm the current statement traces to a weighing and an unbroken amendment chain. Where the chain is broken or the amendments cannot be reconstructed, the closure plan may recommend a re-weighing, but performing one is outside the review itself.
