DJI Agras T20 OEM Landing Gear Bottom Board

The DJI Agras T20 OEM Landing Gear Bottom Board is the long, flat, black fiberglass strip that forms the bottom of the landing gear — the board at the base of the undercarriage, closest to the ground. It is one straight, narrow, rectangular strip with a glossy surface, as shown in the product images, and it is named in the part designation as a fiberglass board. It belongs to the landing gear, not to the spray, power or sensing systems, and it is identified for the DJI Agras T20 and T16. Operators usually find it while searching for a T20 landing gear bottom board, a T16 landing skid board, a T20 fiberglass landing strip, a split landing gear board after a hard landing, or a T16 undercarriage bottom plate. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × Landing Gear Bottom Board — one long, flat, black fiberglass strip

This is the board alone. It is a single flat strip, not a landing gear leg, not a landing gear assembly, and not a set of boards.

Not included: landing gear legs or tubes, landing gear fixing pieces or brackets, screws and nuts, foot pads or shock absorbers, and any other board. Reuse the original fixings only if their threads and heads are sound.

Nothing is included because it appears near the board on the aircraft. If a fixing is missing from your removed assembly, tell us which one and we will help you identify it.

🔧 Component Overview

The bottom board is the lowest structural piece of the T20 and T16 landing gear. It is a plain part: a long, narrow, flat fiberglass strip, black and glossy, with straight edges and square ends. On the aircraft it sits at the base of the undercarriage and is the part of the landing gear that meets the ground.

Its job follows from where it sits and what it is made of:

• The flat face — the surface that meets the ground on landing and spreads that contact along the board's length
• The long edges — where the board is most exposed to stones, stubble and the lip of a trailer bed
• The ends and fixing points — where the board is secured to the rest of the landing gear and where load passes into it

Fiberglass is chosen for parts like this because it flexes a little and springs back, rather than denting like metal. That same property shapes how the board fails, and it is why the failure is easy to miss.

Over a season the bottom board sees:

• Every landing, on every surface the aircraft is set down on
• Hard landings and landings on uneven ground, where one end or one edge takes the load
• Abrasion from soil, gravel, stubble and concrete
• Being dragged or slid across a trailer bed or a tailgate during loading
• Wetting with spray mix and rinse water, then drying in the sun
• Vibration through the airframe on every flight

Bottom boards come out for three reasons: a board snapped outright, a board split or delaminated along its length, or a board whose fixing points have cracked so it no longer holds tight. The first is obvious. The second is the one that gets left on the aircraft.

---

⚙️ Functional Purpose

The bottom board's engineering role is ground contact. It gives the landing gear a flat, slightly flexible base to land on, so the touchdown load is spread along the board instead of concentrated at a point.

In the landing gear it:

• Forms the bottom member of the undercarriage, closest to the ground
• Spreads landing load along its length
• Flexes slightly under load and returns to shape
• Gives the aircraft a stable footprint on soft or uneven ground
• Takes abrasion so the parts above it do not

What it does not do:

• It does not absorb shock the way dedicated shock absorbers or pads do; it flexes, it does not damp
• It does not fold, lock or adjust
• It carries no wiring and has no electrical function
• It does not straighten a bent landing gear leg or frame
• It does not mount the spray system or the sensors

The flex is part of the design. A board that has delaminated flexes more than it should, so the aircraft settles lower on that side and the load it should have spread arrives at the fixings and the legs instead.

Because it is flat, low and made to flex, the board is also the part of the landing gear most likely to be damaged in a way that does not show from above.

🔍 Diagnosis — fiberglass splits along its layers long before it snaps

A snapped bottom board is not a diagnosis problem; the aircraft stands crooked and the break is in plain sight. The board that matters is the one that looks whole.

Fiberglass is built in layers. Under repeated hard landings, or one bad one on an edge, those layers can begin to separate inside the board, or a crack can start at an edge or a fixing point and run along the grain. From above, the glossy black face still looks continuous. The board still holds the aircraft up. But it has lost much of its stiffness, and the next hard landing finishes what the last one started — often at the moment the aircraft is heaviest, with a full tank.

Signs the board has started to fail:

• A pale, whitish line or patch in the black surface, where the layers have separated beneath it
• Frayed or furred fibres along an edge
• A hairline crack running lengthwise from an end or a fixing point
• A board that flexes more than its partner when pressed by hand
• A dull or crackling sound when the board is flexed gently
• The aircraft sitting slightly lower or leaning on one side compared with before

Rule out what imitates it:

• A loose fixing — a board that moves at its fixings can feel weak; tighten or replace the fixing and test again
• A bent landing gear leg or a cracked fixing piece — if the aircraft leans with a sound board, the fault is above it
• Mud or residue on the board — clean it first; dried residue hides cracks and can look like whitening

How to check it. Clean the board, then look along it in raking light from one end — a torch held low across the surface shows delamination as a change in sheen. Look along both long edges and at every fixing point. Press the middle of the board and compare its flex with the board on the other side.

Do that check first, while the aircraft is on the bench and the information is still cheap. A board that shows separation or a lengthwise crack is replaced now, not after it lets go.

⚠️ Common Replacement Indicators

Replace the landing gear bottom board when inspection confirms one of these:

• A break or a crack across the board
• A lengthwise crack running from an end, an edge or a fixing point
• Whitening or a change in sheen showing separated layers
• Frayed fibres or chipped edges along its length
• A cracked or enlarged fixing point that no longer holds tight
• Noticeably more flex than the matching board on the other side
• A previous repair with adhesive, tape or a splint

Inspect these first, because they produce similar symptoms:

• The fixings that hold the board
• The landing gear fixing pieces and brackets
• The landing gear legs or tubes above the board
• The frame where the landing gear attaches

There is no published service interval for the bottom board. It is replaced when it is broken, split, delaminated or no longer held, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down, remove the battery and empty the tank
• Rinse and dry the landing gear so cracks and fixings are visible
• Photograph the board in place from the side and from below, including its fixings
• Support the aircraft on blocks so the landing gear is unloaded
• Lay the new board beside the old one and compare length, width and fixing points
• Lay out a tray for the fixings and keep them grouped by position

During installation

• Release the board's fixings and remove it without levering against the landing gear legs
• Inspect the fixing pieces and the legs above the board while they are exposed
• Clean the mating faces of residue and grit
• Offer up the new board in the same orientation as your photographs show
• Start every fixing by hand before tightening
• Tighten evenly; DJI does not publish a torque figure for these fixings, so snug them without crushing the fiberglass

After installation

• Set the aircraft down on a flat surface and check that it stands level
• Press down on the frame above each landing gear side and compare the flex
• Check every fixing again after the first few flights; new boards can settle
• Run a short hover and a gentle landing before the first loaded flight
• Record the replacement in the maintenance log

Maintenance between jobs. Rinse the landing gear at the end of each day and look along the bottom boards while they are clean. Land on the flattest ground available and avoid dragging the aircraft across trailer beds; most edge damage is done on the ground, not in the air. Treat any whitening or lengthwise crack as a reason to inspect before the next loaded flight.

🚜 Necessary For

This board is for operators and technicians repairing or inspecting the base of a T20 or T16 landing gear:

• DJI Agras T20 operators replacing a board broken or split in a hard landing
• DJI Agras T16 operators (identified fitment)
• Commercial spray applicators who land on stubble, gravel and uneven field edges every day
• Agras service centres and repair technicians rebuilding crash-damaged undercarriages
• Fleet managers who keep a spare bottom board with their T20 and T16 parts
• Growers flying their own aircraft who want the landing gear sound before a full-tank season

This is not the part you need if:

• A landing gear leg or tube is bent — replace the leg; a new board will not straighten it
• A landing gear fixing piece or bracket is cracked — replace that piece
• The board is sound but loose — replace or tighten the fixings
• The frame where the landing gear attaches is cracked — that needs frame repair first
• Your aircraft is not a T20 or T16 — this board is identified only for those two

💡 Why This Part Matters

The bottom board matters because it is the first part of the aircraft to meet the ground on every landing, and it is made of a material that hides its damage. A fiberglass board can separate along its layers or crack along its length and still look like a whole, glossy strip from above.

That is what makes it worth inspecting deliberately. A delaminated board has lost stiffness but not yet failed, and the landing that breaks it is often a full-tank landing — the heaviest the aircraft makes. A board that lets go then puts the load into the legs, the fixing pieces and the frame above it.

The check takes a few minutes with the board clean: raking light along the surface, a look along both edges and at every fixing point, and a press in the middle compared with the other side.

If the board passes, leave it. If it shows whitening, frayed edges or a lengthwise crack, replace it now, while it is a single flat part and not the start of a landing gear rebuild.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 landing gear bottom board? The long, flat, black fiberglass strip at the base of the landing gear — the part of the undercarriage that meets the ground.

Which aircraft does it fit? It is identified for the DJI Agras T20 and T16. Pick the variant for the aircraft you fly.

What is it made of? It is named in the part designation as a fiberglass board. Exact dimensions and weight are not published for this part.

How many boards are supplied? One board.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph the old board beside a tape measure and send it to us if you want that confirmed.

My board is not broken. Can it still need replacing? Yes. Fiberglass can separate along its layers or crack along its length and still look whole from above. Look for whitening, frayed edges and lengthwise cracks, and compare its flex with the other side.

How do I check it properly? Clean it, then shine a torch low across the surface from one end. Separated layers show as a change in sheen. Check both long edges and every fixing point, and press the middle to compare flex.

My aircraft leans to one side. Is it the board? Possibly, but check the landing gear legs, fixing pieces and fixings too. If the board is sound and the aircraft still leans, the fault is above the board.

Does the board absorb shock? It flexes slightly and returns to shape, which spreads landing load. It is not a shock absorber.

Are fixings included? No. The board is supplied on its own. Reuse sound original fixings or replace damaged ones separately.

Can I fit it myself? Most operators can. Support the aircraft on blocks, photograph the board in place, swap it with the same orientation, start every fixing by hand and check that the aircraft stands level.

Is there a torque value? DJI does not publish one for these fixings. Tighten evenly and stop before the fiberglass is crushed.

Is there a service interval? No. Replace it when it is broken, split, delaminated or no longer held. Look along it whenever the aircraft is rinsed.

Will a new board fix a bent landing gear leg? No. The board is the bottom member only. A bent leg or a cracked fixing piece needs its own replacement.

Are the T20 and T16 boards the same? This board is identified for both aircraft. The variant records which one you fly, and we compare against the board you removed if you send a photograph.

Should I replace the boards on both sides together? Not automatically. Replace the board that fails inspection. If the other side shows whitening or frayed edges too, replace it at the same time so both sides flex alike.
