That is why an arm gets replaced for problems as different as a cracked tube, a misaligned motor mount, and a hinge that will no longer lock — all three live in the same assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich arm position do I need — M1, M2, M3, or M4?\u003c\/strong\u003e On this listing the positions are M1 front right, M2 front left, M3 rear right, and M4 rear left, and each carries its own part number (AG-ARM-T40-M1-000401, M2-000402, M3-000403, M4-000404).

That matters because those readings look like a sensor or balance problem and get investigated as one, while the actual cause is a structural member that has moved. On a T40 logging those warnings, the arms are worth inspecting before the search moves to the electronics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the physical signs an arm needs replacing?\u003c\/strong\u003e A bent, cracked, or twisted arm structure, a broken mounting interface, a damaged folding section or worn hinge area, loose fitment or excessive arm movement, difficulty locking the arm, a visibly misaligned motor or propeller position, and cracked cable-routing channels or exposed wiring. Damage is often found during post-incident inspection rather than in flight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat causes T40 arms to fail?\u003c\/strong\u003e The listed causes are hard landings, transport and trailer impacts, folding-cycle fatigue, chemical contact degradation, and vibration stress accumulated across long commercial seasons.
