How the LD-9 is used

A general-purpose closed container on a P1P pallet base, built to the AAP code. The door is canvas with net straps, or solid.

It is effectively an LD-7 pallet with an enclosure added, which is why the base size matches. Two figures matter when planning: the gross rating changes with position, 4,624 kg in a lower hold against 6,000 kg on a main deck, and empty weight depends on which door the unit has.

Cargo it usually takes

  • General air freight
  • Freight already on pallets
  • Retail goods
  • Mixed cargo

How this family is arranged

  • A general-purpose closed container built onto a P1P pallet base.
  • The door is canvas with net straps built in, or solid, which is why empty weight differs between builds.
  • Aluminium sheet on an extruded aluminium frame. The structure stays as light as it can, because every kilogram of empty weight takes the place of paying cargo.
  • A flat base with hardened edge rails locks into the aircraft latch and roller system, so the unit stays put without separate lashing.
  • One or two sides are angled to follow the fuselage curve, so the unit fills the belly cross-section instead of leaving empty corners.
  • The door is either a canvas curtain with restraint straps built in, or a hinged solid panel.
  • Forkable variants have channels so a forklift can move them, as well as a dolly and a loader.

Why operators pick it

  • It fills the curved belly space that loose cargo would leave empty.
  • The whole unit goes on and off in one lift, which keeps the turnaround short.
  • The cargo is restrained in flight, so each piece does not need its own tie-down.
  • Airlines and aircraft can swap the unit under the IATA identification system.

Settle these points before you book

  • Empty weight counts against the payload, so a heavier unit carries less cargo for the same rate.
  • The load must stay inside the contour. Anything above the profile fouls the hold and is rejected at build-up.
  • A canvas door keeps weather out. It is not a secure closure.
