HINGE ASSEMBLY, Upper Left, Bent

• Improved welded design
• Thicker alloy steel
• Better fit and form than the OEM forged hinges
• Heat treated for extra strength and wear resistance
• Straight or bent hinges available
• Available drilled or undrilled

Why is ours better? Our welded steel hinges incorporate design improvements for increased strength and corrosion resistance. To provide you with the best fit, our hinges are available drilled or undrilled. All pre-drilled hinges are also prime painted. Note: hinge halves with an "S" suffix are undrilled and not primed. We're the only manufacturer to offer both straight and bent hinge options, so you get the best possible fit.

Should you choose straight or bent hinges? Cessna legacy airplanes, built prior to 1979, feature a door post skin that angles inward (toward the front edge of the door). Aircraft with this bend require a hinge with a 5° bend for correct installation. Later models and new production aircraft don't have this inward angle and use a straight hinge. We highly recommend verifying your door hinges before ordering, replicating the 5° bend from a straight hinge in the field is very difficult and rarely correct. Note: we don't have exact serial number cutoffs for when hinges went from bent to straight.

Find the right part number: undrilled hinge part numbers carry an "S" suffix, and bent hinge part numbers carry a "B" suffix. Example: P/N MC0511238-7 is straight, versus P/N MC0511238-7B is bent.

We recommend using our Door Hinge Guide to help find the right hinge for your application.

Maintenance tip about door seals: Cessna doors put tremendous leverage on the forward door seals. Door hinges and hinge pins can be easily overstressed and fail if incorrect door seals are installed. Always use approved door seals designed for your aircraft.

Maintenance tip for installation: temporarily attach the replacement hinges to the door using temporary fasteners, install the door and hinge pins, and verify door alignment with the door opening. The leading edge of the door should sit approximately flush with the adjacent door post skin. Minor bends can be made to the upper hinges to perfect the door fit. Reference the ICA.
