This gas spring replaces the original 160-0002 gas spring supplied by Lancair for the nose gear on Legacy and IV* models.

Springs supplied by Lancair were charged for 100lb of force, the 700-0101 gas spring supplied by O’Day Design LLC applies 10% higher force (110lb) which holds the nose strut more securely and also improves the useful life of the gas spring.

The nose gear gas spring is an important part of the emergency extension system, it pushes the nose gear down against the aerodynamic forces placed on the gear in the event of a hydraulic failure.  All gas springs degrade over time, its important to check for proper function of the gas spring in-flight at least annually to ensure it has enough charge to lower the nose strut completely.  It is even better to remove the spring and test it on a bathroom (or similar) scale during annual.

Always install gas springs with the rod end down, this better prevents leakage of the gas charge and properly lubricates the seals inside the unit.

*This spring fits later IV models with 10MM balls on the nose gear, for bolted connections see 700-0099 (GM28).
