SKI TUBE UPPER (P/N 36981-402) - As Removed

The 36981-402 is the upper tube component of an aircraft ski landing gear assembly. This aerospace-grade metal tube transfers structural loads between the ski and the landing gear linkage during wheel-ski operations. The tube interfaces with rigging hardware and attach points in the upper ski assembly, maintaining alignment and load distribution during takeoff, landing, and ground handling.

Installation requires verification against your aircraft's Illustrated Parts Catalog and compliance with FAA-approved maintenance procedures specific to your ski gear configuration.
