Why choose the McFarlane Nose Fork?
The nose gear fork on Cessna aircraft carries every taxi load, crosswind roll-out, and hard arrival the aircraft will experience. When it needs replaced, whether you're complying with AD 71-22-02 or your fork is bent, cracked, or unserviceable, the McFarlane nose fork is the straightforward choice. MC0442503-6 is machined from stronger materials and more resistant to stress-corrosion cracking than the OEM. The alternative used option from a salvage yard has unknown load history, no traceability, and the risk of hidden corrosion and fatigue damage. For Cessna 172, 175, and 182 series aircraft subject to AD 71-22-02, the FAA has also granted an AMOC approving MC0442503-6 as compliant with the AD.
Looking for other nose strut components? McFarlane also has FAA-PMA approved ring retainers, seals, bearings, and the inner barrel.

FAQs
Does this part satisfy FAA AD 71-22-02?
AD 71-22-02 was issued due to reports of cracking in early-style Cessna nose gear forks under high-stress conditions. It requires inspection of the original nose forks and replacement if cracks are found, or no later than 1,800 hours time in service. The terminating action specifies installation of a later-type fork identified by certain forging numbers. The FAA issued an AMOC to AD 71-22-02 approving the use of MC0442503-6 as an alternative means of compliance. Once MC0442503-6 is installed with the AMOC, AD 71-22-02 is no longer applicable to that aircraft
Does MC0442503-6 have an approved AMOC to AD 71-22-02?
Yes. The FAA issued an AMOC to AD 71-22-02 approving the use of MC0442503-6 as an alternative means of compliance. This AMOC is applicable to Cessna 150, 172, 175, and 182 series aircraft affected by the AD. Once installed with the AMOC, AD 71-22-02 is no longer applicable to that aircraft.
How is the fork installed?
Installation follows Cessna service kits SK182-34C or SK205-3B, as applicable to the aircraft. The nose strut inner barrel is pressed into the fork's upper bore with a 0.0005 to 0.0025 inch interference fit. After pressing, the inner barrel is rotated 90 degrees and pressed into the fork. The fork and inner barrel assembly is then installed on the nose gear strut per the service kit instructions. Estimated installation time per the Cessna service kit is approximately 4 hours.
Should I replace the inner barrel at the same time as the fork?
If replacing the nose gear fork, it is worth inspecting the nose strut inner barrel at the same time. The fork's upper bore is a press fit to the inner barrel, and a worn or corroded inner barrel will compromise that fit, degrade strut performance, and expedite wear on all surrounding components. McFarlane offers a PMA inner barrel, part number MCSTRT-C00, as a direct replacement.
Is the McFarlane nose fork better than the OEM part?
The McFarlane nose fork material and machining provide significantly better resistance to stress-corrosion cracking.
What is the McFarlane part number for this nose gear fork?
The McFarlane FAA-PMA nose gear fork is part number MC0442503-6.
What OEM part number does MC0442503-6 replace?
MC0442503-6 replaces Cessna/Textron OEM P/N 0442503-6, also identified by forging number 0442503-497. This part appears in Cessna service kits SK182-34C and SK205-3B as the replacement nose wheel fork.
