Cargo Manifest Discrepancy on a Freighter Rotation
A freighter operating a scheduled rotation from Campinas to Manaus carries 14 pallets. The manifest declares 12 pallets of general cargo and two pallets of lithium-ion batteries in UN 3480 packing instruction 965, section IA. During ramp inspection the loadmaster notes that the battery pallets are marked with the section IB marking, and the shipper's declaration lists a state of charge of 40 percent. The aircraft commander is asked to sign the acceptance check. The operator's dangerous goods manual requires the commander to verify that the load matches the notification to the commander. The shipper's declaration and the physical marking disagree, and the flight is already behind schedule by 90 minutes.
1. What should the commander do before accepting the load, and why is the discrepancy material?
Read the worked answer
The commander should refuse to accept the battery pallets until the discrepancy is resolved, and should not sign the acceptance check on the basis of an inconsistent declaration. The notification to the commander must reflect the actual dangerous goods on board; if the physical marking indicates a different packing instruction section than the declaration, the commander cannot verify that the load matches the notification.
The discrepancy is material because the packing instruction section determines the packaging performance standard, the quantity limits, and the state-of-charge conditions applicable to the shipment. A declaration citing one section while the package bears another section's marking means either the package was not tested to the declared standard or the declaration is wrong. Either way, the commander has no reliable basis for the acceptance decision. Schedule pressure is not a permissible factor in that decision.
2. Explain how the state-of-charge value should be treated in the acceptance decision.
Read the worked answer
The state of charge is a condition of transport for lithium-ion cells and batteries shipped under the relevant packing instruction, and it must be declared and verifiable. A declared value of 40 percent is not automatically unacceptable, but the commander and the ground acceptance staff must confirm that the value is consistent with the applicable requirement for the specific packing instruction section and that the shipper has provided the supporting documentation.
The reasoning is that the state of charge affects thermal risk in transport, so it is part of the hazard assessment, not a formality. If the declared value conflicts with the packing instruction section cited, the commander cannot determine which condition applies. The correct action is to hold the shipment, obtain a corrected declaration and evidence from the shipper, and only then complete the acceptance check and the notification to the commander.
3. The operator later proposes to resolve such cases by having the loadmaster sign the acceptance check instead of the commander. Evaluate this proposal.
Read the worked answer
The proposal misallocates the responsibility. The acceptance check and the notification to the commander exist so that the person in command of the aircraft has the information needed to make operational decisions in flight, including emergency response. Delegating the signature to the loadmaster does not transfer that operational knowledge to the commander, and it weakens the verification step the manual requires.
A better design is to keep the commander's verification but make it efficient: a pre-loaded notification generated from the accepted manifest, with a defined escalation path when the physical marking and the declaration disagree. The loadmaster can perform the physical check and raise the discrepancy, but the commander must still receive and confirm an accurate notification. The proposal should be rejected, and the operator should instead fix the acceptance process that allowed a mismarked pallet to reach the ramp.
