McFarlane Aviation Products FAA-PMA Replacement Aircraft Parts

Custom Seat Rails



McFarlane can fabricate custom seat rails to your specifications when replacements are no longer available or for special applications. We manufacture high quality custom cargo and seat rails built to customer provided specifications, utilizing the same stringent manufacturing and quality processes as we do with our PMA rails. This provides our customers with proven technology that delivers the product on time, on budget, with superior corrosion resistance and added strength. We have a variety of extrusions available for use in your design, as well as state of the art CNC machines for precision cuts and finish. Custom seat rails are not FAA-PMA approved. The user must obtain the proper FAA approvals to use our custom seat rails on certificated aircraft. 
For more information, please view the Custom Seat Rail and/or the Custom Brownline Design Forms.
