An aircraft Unit Load Device (ULD) is either an aircraft container or a combination of an aircraft pallet and an aircraft pallet net for grouping and restraining cargo, mail and baggage for air transport. Since the 1950s, they’ve been used to safely transport goods by air. However, year after year, ULDs are often a leading cause of aircraft damage on the ground and also costs the industry about USD 400 million annually for the repair and loss.

To help reduce ULD related safety incidents as well as damage and loss, IATA has developed the ULDR. The ULDR is a comprehensive reference manual containing all the regulatory and airline requirements, technical and operating specifications as well as industry agreed standards and procedures applicable to all parties involved in the manufacturing, repair and maintenance, handling and operations of ULDs.

Significant changes to the latest edition: 

Throughout the ULDR all references to ‘Carrier’ and ‘Airline’ have been changed to ‘Operator’ to align with ICAO and all version letters of SAE standards in general references have been deleted. 

Other changes include:

  • Section 2: Addition of Airbus A350 cargo hold cross-section drawing as well as the information on its acceptable pallet sizes
  • Section 4, SS 40/1 Attachment ‘A’:  Addition of Airbus A350 to the relevant aircraft acceptability information
  • Section 6, OS 6/02: Clarification of the requirements for net attachment point locations
  • Section 7 SS 40/3:  Clarification of ODLN for certified aircraft ULD and improvement on ODLN standard formats
  • Section 10: Complete deletion of current contents as standards for ‘Non-Aircraft Modular Load Units’ as they are  not only outside the scope of ULDR but also no longer in use or supported in the industry
  • Appendix H: Improvements to the illustration of ULD components and sub-components
