About this document
Proposed AD for Learjet Hydraulic System by bombardierwatch is a document available to read on EtoBox.
This document proposes an airworthiness directive for certain Learjet models that would require replacing the spherical accumulator for the main hydraulic system with a cylindrical accumulator due to reports of failures of similar accumulators. Fatigue cracks were found in four thrust reverser accumulators. The proposed replacement is intended to prevent failure of the main hydraulic accumulator from fatigue cracking, which could result in loss of hydraulic power and control of the airplane.
