For how long must the originating aircraft operator retain a copy of the shipping document for hazardous material?

The requirement for retaining a copy of the shipping document for hazardous materials is set by the Department of Transportation and related regulatory guidelines. Specifically, the correct duration for which the originating aircraft operator must retain a copy of the hazardous materials shipping document is 90 days. This retention period ensures that records are kept in case of inspections or incidents related to the transportation of hazardous materials, which are subject to strict safety and regulatory scrutiny.

Retaining the documentation for 90 days allows for adequate review and verification processes to ensure compliance with safety regulations and to protect the safety of personnel, the general public, and the environment. The regulation reflects an understanding of the complexity and risks associated with transporting hazardous materials, emphasizing the importance of accountability in this area of aviation operations.
