DJI Matrice 400 Aircraft Arm Assembly – Position Selectable
This position-selectable aircraft arm assembly is built for DJI Matrice 400 airframe repair when only one damaged arm position needs replacement. Buyers can select the exact aircraft position required: Front Right, Front Left, Rear Left, or Rear Right.
Each variant is supplied as the structural arm unit shown in the reference configuration, including the carbon-fiber arm tube and integrated upper/lower mounting structure. This listing is for the selected structural arm assembly only and does not include a motor, ESC, propeller, or internal wiring unless those items are explicitly shown or stated.
Available Position Variants
- Front Right
- Front Left
- Rear Left
- Rear Right
Package Contents
1 × DJI Matrice 400 aircraft arm assembly in the position selected at checkout.
Component Overview
The Matrice 400 arm structure is a primary airframe component that carries propulsion-side loads and maintains the aircraft's arm geometry. The carbon-fiber tube and mounting structures must remain rigid and correctly aligned for proper installation of the propulsion system and surrounding airframe components.
Primary Function
- Replaces one damaged Matrice 400 aircraft arm position
- Restores structural rigidity and arm geometry
- Provides a position-specific replacement for targeted airframe repair
- Supports repair-shop and fleet-maintenance workflows without requiring a full four-arm set
Replace the Arm Assembly When
- The carbon-fiber tube is cracked, crushed, split, or delaminated
- The upper folding/rotating joint structure is damaged
- The lower arm mounting interface is fractured, distorted, or misaligned
- The aircraft has sustained an impact that compromises arm rigidity or geometry
- A single position needs replacement while the remaining arms are serviceable
Fitment

Position Selection Is Critical
Matrice 400 arms are position specific. Choose the exact aircraft position required before ordering. Front Right, Front Left, Rear Left, and Rear Right should not be treated as interchangeable variants.
Installation / Ordering Notes
Before installation, verify the selected arm position against the aircraft being repaired. Transfer or reinstall any required propulsion components, wiring, fasteners, covers, and related hardware according to the aircraft service procedure. Professional installation is recommended for structural aircraft repairs.
For Operators, Repair Shops & Fleets
This listing is intended for commercial Matrice 400 operators, enterprise fleets, service centers, and repair teams that need a single position-specific replacement rather than the complete four-arm set.
Why This Part Matters
The aircraft arm maintains propulsion positioning and carries structural loads between the propulsion end and central airframe. A damaged arm can affect alignment, rigidity, and the integrity of the aircraft structure, making correct position selection and replacement important before returning the aircraft to service.

Common Questions
Can I choose the exact arm position?
Yes. Select Front Right, Front Left, Rear Left, or Rear Right from the position menu before checkout.
Are all four positions interchangeable?
No. The positions are aircraft-specific. Order the exact position required for the repair.
Does this listing include all four arms?
No. This listing includes one selected arm assembly. A separate complete four-arm set listing is available when all four positions are needed.
Are the motor and ESC included?
No. This listing is for the structural arm assembly shown. Propulsion and electronic components are not included unless explicitly stated.
