Save 16 + hours per main‑gear change
side & drag stays remain fitted, so preparation and rigging steps vanish.
Ground‑based, all‑electric control
no cranes, no on‑wing work, just two engineers and an 8″ HMI touchscreen for precise joystick moves.
One tool, every wide‑body
adaptors cover A330/A340, A350‑900/‑1000, A380, 777 (incl. X) and 787 families.
Overview
LGX MultiSystem is RH Aero’s next‑generation, pallet‑shippable trolley for main‑landing‑gear R/I. An electric X/Y/Z drive, digital‑twin support and single‑operator HMI turn a high‑risk, crane‑intensive job into a fast, repeatable ground‑level procedure that protects staff, airframe and schedule.
Details
- 8″ touchscreen + three joysticks with wired or wireless operation for millimetre‑accurate moves.
- Tool‑Centre‑Point logic lets the operator set one fixed pivot, so the gear never drifts.
- Digital twin for VR training, live load‑cell read‑outs and remote diagnostics.
- IP54 / CE / UL rated electronics for indoor or apron use.
- Ships worldwide on a single ULD pallet – no exceptional transport needed.

Traditional Process
- Overhead sling/crane method
- Wing top skin to be removed
- Controlled movements not possible
- Risk of damage to gear and airframe
- High manpower required to control movements
LGX MultiSystem Process
- Ground based method
- No need to remove wing top skin*
- Gear always in fully controlled position
- Significant reduction of risk of unintended movements
- Less manpower required (1x tool operator + 1x trunnion pin R/I)
* A350 & B787: avoiding top skin removal requires LGX-compatible actuator R/I adaptor (development in progress)
Customer Story
British Airways Maintenance Cardiff proves the LGX advantage
During a 12‑year heavy check in July 2025, two BAMC engineers completed a Boeing 787‑8 main‑landing‑gear change with the LGX MultiSystem and no overhead crane. Real‑time load‑cell monitoring kept bearing loads within AMM limits, while side‑ and drag‑stay assemblies remained fitted, eliminating a major removal/re‑installation sequence and cutting man‑hours dramatically. Engineer Richard Langdon summed it up:
“The gear never moved unless we told it to, so the job felt far safer and more controlled than the conventional method.”
Business impact
BAMC released the Dreamliner back to the flight schedule sooner, generated additional hangar capacity for parallel projects, and lowered both labour and tooling overheads — all while improving safety margins with real‑time load‑cell monitoring and fully controlled, ground‑based movements.
Field experience on the first 787‑8 gear change shows a double‑digit hour reduction because side‑ and drag‑stays stay on the landing gear and no crane rig‑up is necessary.
Adapters for Airbus A330, A340, A350‑900/‑1000, A380‑800 and Boeing 777 (all variants) plus 787‑8/‑9/‑10 are qualified, with further validations under way.
No. The ground‑based trolley keeps the gear fully supported, so wing‑skin removal is avoided on 787 and A350 models.*
* A350 & 787 actuator work: avoiding top‑skin removal requires an upcoming LGX‑compatible actuator R/I adapter (development in progress).
Yes — the base unit is IP 54‑rated and CE/UL‑compliant, making apron or remote AOG work possible.
