1159GSE50214-1 – Gulfstream Aerospace OEM Main Landing Gear Jackpad Adapter
Available now on the Airparts.aero Marketplace.
Overview
The Gulfstream 1159GSE50214-1 is a genuine OEM, safety-critical piece of Ground Support Equipment (GSE), specifically a Main Landing Gear Jackpad Adapter. This is not a simple pad; it is a heavy-duty, precision-machined structural tool engineered for the safe and precise jacking of Gulfstream large-cabin business jets, including the G-IV and G-V series. It is designed to interface perfectly between the main landing gear's designated hard-point and the lift ram of a standard aircraft hydraulic jack.
Its sole purpose is to distribute the immense weight of the aircraft over a specific, load-bearing area of the gear structure, preventing any damage, cracking, or slipping during lifting procedures. As the factory-specified tool, its use is mandatory for any maintenance requiring the main gear to be lifted, such as wheel changes or brake service.
Key Features
Genuine Gulfstream OEM Tool: The only tool certified and approved by Gulfstream for this procedure, guaranteeing correct fit, safety, and compliance with the maintenance manual.
Precision-Machined Fit: CNC-machined from high-strength material to mate perfectly with the unique contour of the Gulfstream main landing gear jacking point.
Safe Load Distribution: Engineered to distribute tens of thousands of pounds of jacking force across the designated load-bearing structure, preventing point-loading and catastrophic damage to the gear.
Safety-Critical GSE: Designed to ensure the stability of the jacked aircraft and prevent the jack from slipping off the gear, protecting both technicians and the airframe.
Heavy-Duty Construction: Fabricated from high-strength aluminum alloy (e.g., 7075-T6) or steel to withstand the immense compressive loads of lifting the aircraft.
Durable Finish: Anodized or painted for a long service life and to protect against corrosion and wear in the demanding hangar environment.

Gulfstream: G350, G450, G500, G550
Note: This compatibility list is for general reference. The specific Gulfstream Aircraft Maintenance Manual (AMM) is the final and absolute authority for determining the correct jacking tool part number for a given aircraft serial number.
Applications
Aircraft Jacking: The primary tool for lifting the main landing gear to perform maintenance.
Wheel & Tire Service: Required for removing and installing main gear wheels.
Brake Service: Essential for performing maintenance, inspection, and replacement of the main gear brake assemblies.
Landing Gear Maintenance: Used for any retraction tests, strut servicing, or repairs that require the gear to be off the ground.
Why Choose 1159GSE50214-1?
Jacking a multi-million dollar Gulfstream is a high-risk procedure. The 1159GSE50214-1 is the only tool certified and engineered by Gulfstream for this task. Using an improvised, unapproved, or non-certified pad can lead to catastrophic jack slippage, a cracked landing gear trunnion, or damage to the jacking point, resulting in an AOG (Aircraft on Ground) situation and a repair costing hundreds of thousands of dollars. The genuine Gulfstream OEM tool is a non-negotiable investment in safety, ensuring the protection of the maintenance technicians and the structural integrity of the aircraft.
The engineering principle behind the 1159GSE50214-1 is the safe management of the jacking load path. The landing gear jacking point is a reinforced hard-point designed to accept the full weight of the aircraft, but only when that load is applied in the specific vector and over the specific surface area defined by the manufacturer. This adapter is a structural "key" that fits into the "lock" of the jacking point. Its precisely contoured and machined surfaces ensure that the millions of foot-pounds of force from the jack are transmitted only to the designated load-bearing structures, completely isolating adjacent, non-structural components from any stress, thereby guaranteeing the integrity of the landing gear.
Note: The 1159GSE50214-1 is a safety-critical piece of Ground Support Equipment. It must be inspected for cracks, deformation, or damage before each use. It must only be used by trained and qualified personnel in strict accordance with the jacking procedures outlined in the Gulfstream Aircraft Maintenance Manual (AMM). Always use in conjunction with a properly rated aircraft jack on a level surface.
