Marsh Brothers M1001 MLG DOOR HINGE KIT - BARON

The **Marsh Brothers Aviation Baron Main Landing Gear (MLG) Door Hinge Kit** (P/N **M1001**) is designed to replace the main landing gear door hinge bushings and associated installation hardware on eligible Beechcraft Baron aircraft. Traditional metal bushings require periodic lubrication and can be difficult to access during maintenance. If they are not lubricated regularly, corrosion may cause the bushing and sleeve to seize together. This can affect landing gear door rigging and operation and may contribute to damage to the door or its supporting structure. The M1001 kit uses non-metallic **AeroTough® GF polymer bushings** with inherent self-lubricating properties. These bushings provide smooth, grease-free operation and do not require periodic lubrication. The kit contains the bushings, corrosion-resistant steel sleeves and hardware required for **two main landing gear doors**. ### Kit Contents | Part Number | Description | Quantity | OEM Cross-Reference | |---|---|---:|---| | AN3-10A | Bolt | 8 | AN3-10A | | MBA10006 | AeroTough® GF bushing | 10 | LG-BSH001-1, LG-BSH001-3, 58-810022-1, 58-810022-3, 105739X-ZM0500, 105739X-ZP0500, 105740X-ZR0480 | | MBA10058S | Short CRES sleeve | 6 | N/A | | MBA10058L | Long CRES sleeve | 2 | N/A | | AN960-10 | Washer | 32 | AN960-10 | | AN365-1032A | Nut | 8 | AN365-1032A | | AN3-15A | Bolt | 2 | AN3-15A |
