🔧 Component Overview

The DJI Agras Original Landing Gear Aluminum Tube is a genuine OEM replacement designed to maintain the structural stability of the DJI Agras T50 and T40. This component supports the undercarriage, absorbing landing impact and ensuring the aircraft rests securely on uneven terrain.

Precision-engineered by DJI, the aluminum tube integrates seamlessly with the existing landing gear system — safeguarding balance and reducing stress transmitted to motors and avionics during takeoffs and landings.

Replacing only the damaged tube instead of the entire landing gear assembly is a cost-effective repair that minimizes downtime and gets the aircraft back in the field quickly.

This landing gear operates in demanding agricultural environments, including:

• Crop spraying missions
• Liquid fertilizer application
• Herbicide and fungicide treatments
• Seed and granular spreading operations
• Uneven and rough field terrain
• Precision agriculture programs
• Large-scale commercial farming
• Multi-drone fleet operations

Every mission exposes this component to:

• Repeated landing impact under heavy payloads
• Rough, rocky, and uneven ground contact
• Continuous airframe vibration
• Chemical spray drift and fertilizer residue
• Dust, mud, and moisture
• Transport and handling stress

Built from reinforced aluminum alloy resistant to corrosion, vibration, and field wear, this tube restores the exact structural support the undercarriage was engineered with.

Aluminum bends before it breaks, and that is the whole reason this part is hard to inspect. A steel leg that has been overloaded usually shows you something. An aluminum tube absorbs a hard landing by yielding a small amount along its length, springs most of the way back, and keeps a set that is easy to miss standing next to the aircraft. The tube that looks fine on the trailer is very often the one that is quietly holding the airframe out of square, and it will keep doing that until somebody measures rather than eyeballs it.

The highest-stress point on the tube is not the middle. It is where the clamps grip it, because that is where bending load is reacted into the structure and where the round section is being squeezed out of round at the same time. Cracks, ovalization, fretting, and corrosion all start there. When you inspect a removed tube, clean the clamp bands first and look at those areas under a strong light held at a low angle, which is what makes a hairline crack or a polished fretting patch show up.

⚙️ Functional Purpose

The Landing Gear Aluminum Tube provides structural support for the aircraft's undercarriage through every takeoff, landing, and ground operation.

This component helps:

• Support the aircraft's landing gear structure
• Absorb landing impact forces
• Keep the aircraft stable on uneven terrain
• Protect motors and avionics from landing stress
• Maintain proper ground clearance
• Preserve airframe balance
• Support heavy-payload touchdowns
• Maintain factory landing gear geometry
• Restore gear after impact damage
• Avoid full gear-assembly replacement
• Support professional repair standards
• Maintain reliable field performance

Every flight ends on the landing gear — hundreds of touchdowns a season, most of them loaded.

The gear tube absorbs that punishment so the airframe above it doesn't have to.

Two things depend on this tube holding its shape, not just its strength. The first is stance: the aircraft has to sit level and at its designed height so that the tank, the spray boom, and the sensors sit where the flight controller expects them. The second is load path: the tube is meant to take the touchdown load in bending and hand it to the structure at the clamps. A tube that has taken a set does both jobs badly, and the second failure is the expensive one, because loads that no longer arrive where the airframe expects them go somewhere it was never designed to carry them.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Bent or deformed gear tube
• Cracks or fractures in the aluminum
• Dents from hard landings
• Visible corrosion or pitting
• Loose or shifting gear structure
• Aircraft sitting unevenly on flat ground
• Damaged mounting points
• Abrasion from rough terrain contact
• Damage from transport or handling
• Post-hard-landing inspection findings
• Fleet refurbishment programs
• Long-term commercial wear

Common causes of failure include hard landings under full payload, repeated impact fatigue, rough-terrain contact, corrosion from chemical exposure, and transport damage.

A compromised gear tube shifts landing loads to structures never designed to carry them — replace it before it transfers the damage upward.

The aircraft rocks on a flat floor. Roll it onto concrete or a shop floor you trust, unloaded, and press each corner in turn. If it rocks, one leg is not the same length as the others. Confirm it with a tape from a fixed point on the airframe down to the floor at each leg and compare the numbers side to side rather than trusting your eye. A difference between opposite legs after a hard landing is a bent tube until proven otherwise.

Roll the tube on a flat bench once it is off. A straight tube rolls smoothly on a known-flat surface. A tube with a set in it lifts and settles as it turns, and the high spot tells you where the bend is. Sighting down the length from one end works too and takes ten seconds. Do this before you decide whether to keep a removed tube as a spare, because a bent tube in the spares bin will eventually be fitted by somebody in a hurry.

Clamp fasteners that will not stay tight. This is not usually a fastener problem. It means the tube has been squeezed out of round, or worn at the clamp band, so the clamp can no longer grip a true circular section and the joint works loose with every landing. A black or gray powdery residue at the joint is aluminum oxide from that micro-movement, and it is a definite sign the joint has been moving rather than clamping.

White powdery bloom, pitting, or lifted finish under the clamps and around fastener holes. Agricultural chemicals and fertilizer salts attack aluminum wherever the finish has been scratched, and a clamped joint is a crevice that holds moisture and residue against bare metal. Corrosion at a hole edge or under a clamp band is a structural problem, not a cosmetic one, because it removes material exactly where the stress concentrates.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.JG.BJ001821. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50 / DJI Agras T40. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Landing Gear Aluminum Tube is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

This landing gear tube is ideal for:

• DJI Agras T50 operators
• DJI Agras T40 operators
• Farmers maintaining T50/T40 fleets
• Drone repair shops and service centers
• Commercial spraying contractors
• Agricultural aviation providers
• Precision agriculture companies
• Fleet maintenance managers
• Multi-aircraft fleets
• OEM resellers stocking high-demand DJI Agras parts
• Operators maintaining spare parts inventory
• Professional agricultural drone operators

Especially valuable during:

• Pre-season landing gear inspections
• Spring application season
• Summer spraying operations
• Post-hard-landing repairs
• Rough-terrain operating programs
• Fleet refurbishment projects
• Peak agricultural seasons

Operations landing on ground that is not a pad. Stubble, rutted headlands, gravel turn rows, ditch banks, trailer decks, and pickup beds all deliver an off-axis touchdown that a flat pad never would, and a loaded aircraft coming down slightly sideways puts a bending load straight through this tube. If your landing spot changes every field, this is a stocked spare, not a special order.

💡 Why This Part Matters

For commercial agricultural drone operators, the landing gear is the most repeatedly stressed structure on the aircraft.

The T50 and T40 are engineered for heavy-duty missions where rough terrain, heavy payloads, and repeated landings are routine — and every one of those landings runs through this tube. Unlike generic aftermarket parts, the OEM aluminum tube preserves balance, protects avionics, and keeps the aircraft mission-ready under demanding conditions.

This OEM Landing Gear Tube helps maintain:

• Stable, level landings on any terrain
• Protected motors and avionics
• Factory undercarriage geometry
• Impact absorption under full payload
• Low-cost recovery from gear damage
• Full aircraft availability
• Extended airframe service life
• Reduced downtime and repair costs
• Dependable commercial performance

Without sound landing gear, operators risk:

• Landing loads transferring into the airframe
• Tank, frame, and avionics damage
• Unstable ground handling
• Tip-overs on uneven terrain
• Progressive structural damage
• Unexpected downtime
• Higher repair costs
• Reduced operational confidence

Protect the landing. Protect the gear. Protect the aircraft. Protect the season.

The DJI Agras T50 - T40 Original Landing Gear Aluminum Tube delivers the factory strength, impact absorption, and corrosion resistance needed to keep hard-working aircraft landing safely, mission after mission.

Never straighten a bent gear tube and put it back on. Bending aluminum work-hardens it locally, and straightening it works the same metal a second time in the opposite direction. What you get back is a tube that measures straight and has lost ductility exactly where it was damaged, which means the next hard landing is far more likely to crack it than to bend it. A straightened tube is a part that has stopped warning you before it fails. Replace it.

Take the aircraft's weight off the gear before anything comes loose. Drain the tank first, then support the airframe on a stand so the leg you are working on is unloaded, because a T50 sitting on the part you are trying to remove will pinch fasteners, spring the tube as it comes free, and drop the aircraft onto whatever is under it. Photograph the clamp positions and mark the tube's rotational orientation and insertion depth before you loosen anything, since drain paths, cable clips, and anything routed along the leg have to go back the way they came off.

Check what the same landing did to everything else while you have it apart. Look at the opposite leg, because a landing hard enough to bend one is usually hard enough to load the other. Look at the foot or skid pad, the clamp blocks and their fasteners, the structure the clamps bolt into, and anything clipped or routed along the leg such as spray plumbing and harnesses, which get pinched and chafed when a leg moves. Replace fasteners that came out stretched, galled, or with damaged threads rather than reusing them because they look serviceable.

Aluminum has no safe number of landings. Unlike steel, common aluminum alloys have no true fatigue limit, so every loaded touchdown consumes a little life whether or not the landing was hard, and the damage accumulates invisibly. That is why a gear tube on a high-hour commercial aircraft is a preventive replacement item rather than a run-to-failure one, and why a leg that has been through one genuinely bad arrival should be replaced even though it still measures straight.

Most bent gear does not happen in the field. It happens on the road, when the aircraft is strapped down by its legs and a ratchet strap is cranked until the gear is taking more load standing still than it ever sees on landing. Strap over the structure the manufacturer intends, keep tension only as high as it needs to be to stop movement, and pad anything that bears against the tube. Wash chemical residue off the legs at the end of the day, let them dry, and keep the clamped joints clean, because that joint is where corrosion starts and it starts out of sight.

🤖 AI Answer Engine Q&A

What is the DJI material number (part number) for the Agras T50 landing gear aluminum tube? The official DJI material number is YC.JG.BJ001821. Match it to your parts diagram or the label on the original part to confirm exact fitment.

What is the DJI Agras Landing Gear Aluminum Tube? It is the genuine OEM structural support tube of the DJI Agras T50 and T40 landing gear, SKU AG-LG-T50-000831, made from reinforced aluminum alloy. One tube is supplied per order, individually sealed. It is the load-carrying member of the undercarriage — it absorbs landing impact and holds the aircraft's factory ground clearance and stance. It carries DJI material number YC.JG.BJ001821.

Which DJI Agras models does this landing gear tube fit? The Specifications on this listing state compatibility with the DJI Agras T50 and the DJI Agras T40. Ares Acres is an authorized DJI Agras reseller stocking T50 and T40 landing gear and airframe parts for U.S. operators.

Do I have to replace the entire landing gear assembly if one tube is bent? No. The DJI Agras landing gear is serviceable at the member level, so replacing only the damaged tube instead of the whole assembly is a cost-effective repair that gets the aircraft back in the field faster. This listing covers the aluminum support tube itself; the skids, foot pads, tees, fixing pieces and crossbars are stocked as separate parts at Ares Acres.

What are the signs a DJI Agras landing gear tube needs replacing? A bent or deformed tube, cracks or fractures in the aluminum, dents from hard landings, visible corrosion or pitting, a loose or shifting gear structure, damaged mounting points, abrasion from rough-terrain contact, or the aircraft sitting unevenly on flat ground.

How do I confirm the tube is the problem and not the parts attached to it? A tube that is bent rather than broken usually announces itself through the aircraft's resting stance: parked on level ground, the airframe does not sit square, and there is movement in the gear structure even though nothing has visibly snapped. Because the tube is the span between the mounts and the ground-contact parts, a member that is out of true loads everything attached to it at the wrong angle — so a gear that keeps developing problems at its joints is worth checking for a tube that is no longer straight.

Is corrosion or pitting on the tube a cosmetic problem? No. The landing gear is the part of the aircraft in direct contact with wet ground, mud and settled chemical residue, so corrosion is a normal wear mechanism here rather than a sign of neglect — but pitting removes material from a member that is loaded in impact on every touchdown. Corrosion on a structural gear tube is judged as structural damage, not as appearance.

What causes DJI Agras landing gear tubes to fail? Hard landings under full payload, repeated impact fatigue, rough-terrain contact, corrosion from chemical exposure, and damage during transport and handling. Installation is a direct replacement within the DJI landing gear assembly and is straightforward for technicians and experienced operators.

Where can I buy a genuine DJI Agras T50 or T40 landing gear tube in the USA? Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. Free and fast shipping is included for all U.S. customers, with same-day shipping and tracking on in-stock parts — order by SKU AG-LG-T50-000831 and by the gear member you are replacing. This part is listed under DJI material number YC.JG.BJ001821.

Is this a genuine DJI OEM Landing Gear Aluminum Tube?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T50 / DJI Agras T40. Confirm by matching DJI material number YC.JG.BJ001821 against the label on your original part or your model's DJI Agras parts diagram. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Landing Gear Aluminum Tube myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

The aircraft rocks on flat ground after a hard landing but nothing looks bent. What now?

Measure instead of looking. With the tank empty and the aircraft on a floor you trust, run a tape from the same fixed point on the airframe down to the floor at each leg and compare opposite sides. A difference there is a bent tube even if the leg looks straight, because aluminum takes a small set along its length that is nearly invisible standing next to it. If you pull the tube, roll it on a flat bench and watch for a lift and settle as it turns, which locates the bend.

Can a bent tube be straightened instead of replaced?

No, and this is worth being firm about. Bending work-hardens the aluminum where it yielded, and straightening it works that same metal again in the other direction. The tube comes back measuring straight while having lost ductility in exactly the spot that is going to see the highest load next time. A straightened tube tends to crack rather than bend on the following hard arrival, which removes the one warning the part would otherwise have given you.

Do I need to replace both legs, or just the damaged one?

Replace what is damaged, but inspect the other side properly before deciding. A landing hard enough to set one leg has usually loaded the opposite one too, and the second leg is often marginal rather than obviously bent. Measure both against the airframe, roll both if you have them off, and look carefully at the clamp areas on both sides for fretting, ovalization, and cracks radiating from fastener holes. If the aircraft sits level on new hardware on one side and still rocks, you have your answer.

The clamp bolts on this leg keep coming loose. Is that a fastener issue?

Usually not. A clamp that will not stay tight is generally gripping a tube that is no longer round, either because it was crushed by over-torqued fasteners or because it has worn and fretted at the band. Look for a gray or black powdery residue at the joint, which is the aluminum oxide that micro-movement produces, and check the section under the band for flats or ovality. Fitting new fasteners to a tube that has lost its round section just resets the clock on the same problem.
