Seat Adjustment Springs for Piper Aircraft
Replacement springs just got more affordable!
Replacements for both styles now available:
Gas Spring Style - P/N MC587-404
*Some Piper parts catalogs do not list part number 587-404 separately, but list an assembly part number of 89178-010 instead. McFarlane P/N MC587-404 replaces the spring component of this assembly and adapter P/N MC37902-06 replaces the block.
Coil Spring/Hydraulic Style - P/N MC555-692
Maintenance Tip: Aircraft make, model and serial number are not sufficient to ensure the correct replacement spring as many aircraft may have been originally equipped with either one or retrofitted with a conversion kit. If the spring you are replacing is marked with a brand name (e.g. P. L. Porter or Stabilus) the correct replacement is readily identified. The coil spring/hydraulic style are also identifiable by a 1-1/4" diameter visible coil spring. The thread may also be measured to verify the correct identification. ![]() Original Gas Spring Style ![]() Original Coil Spring/Hydraulic Style |
