What should a rigger do if unable to comply with alteration record-keeping requirements?

In situations where a rigger is unable to comply with alteration record-keeping requirements, the most appropriate action is to refuse to perform the alterations. This is because compliance with regulatory standards is critical in maintaining safety and accountability in aviation operations. If a rigger cannot meet the established protocols for documenting any alterations, it indicates that there may be potential risks involved that could impact safety.

Refusing to perform the alterations ensures that no unsafe or unrecorded changes are made to the aircraft, thereby upholding the integrity of the operations and ensuring that any work done can be tracked and evaluated later if necessary. It also reinforces the importance of adhering to established guidelines, making sure that both the rigger and the organization operate within the legal frameworks set forth by the regulatory bodies.

The other choices suggest actions that may undermine safety or accountability, either by skipping necessary documentation or relying on verbal notes, which lacks the required formality and can lead to confusion or disputes in the future. Therefore, refusing to perform the alterations is the correct course of action when unable to comply with record-keeping requirements.
