This seat rail has seat adjust holes.
It also has a notch that goes around the sheet metal doubler located on the inside of the rail not by the doorpost. The IPC shows 0511243-5 as Outboard RH and 0511243-6 as Outboard LH. The IPC is incorrect; McFarlane has verified MC0511243-5 is the Outboard LH and MC0511243-6 is Outboard RH.
Seat Rails for Cessna Aircraft
- Carefully engineered with many improvements
- Added strength and longer life
- Anodized for corrosion and wear resistance
- Easier installation
- Full interchangeability with the original Cessna parts
No Pre-Drilled Rivet Holes for Precise Installation
McFarlane seat rails do not have pre-drilled rivet holes in the rail base allowing the installer to exactly match the aircraft floor rivet pattern. McFarlane discovered while installing and developing our replacement seat rails that the seat rail attachment hole pattern was not consistent from aircraft to aircraft. Even small inconsistencies in the hole locations in the aircraft floor make installation of new seat rails very difficult. For this reason, McFarlane does not pre-drill rivet holes at the factory. (Existing stock may have a few pilot attachment holes drilled at the factory.) This allows the installer to precisely locate the attachment holes to match the holes in the aircraft floor. All special sized or machined attachment holes are machined to finish dimensions. It is necessary to replace all fasteners when the seat rails are installed.
More Material in the Right Places
After studying countless worn and failed seat rails McFarlane's rails were designed with 15% more metal in critical areas. The result is more crack resistance, durability, strength and longer life.

For easier installation of seat rails, we also offer Seat Rail Templates, Rivet Kits, Screw Kits and Spotface kits. For guidance on the replacement of fasteners, see FAA Special Airworthiness Information Bulletin CE-90-03R2.
FAA Airworthiness Directive 2011-10-09 requires regular inspection of Cessna seat rails and related parts. For convenient tools to facilitate inspections per this AD, please see the GAUGE SR1 seat rail wear gauge and TOOL110 seat roller housing gauge.

Installation Tip:
The aircraft floor is subject to corrosion from moisture under seat rails. Be sure to remove and treat any corrosion before installing the new seat rails.
