This document is a Justification for Qualification Requirements for an Overhaul/Modification of B-1 Horizontal Stabilizer Servocylinder. The document covers multiple NSNs and Part Numbers related to a critical aerospace component for the B-1 aircraft's primary flight control system. The horizontal stabilizer servocylinder consists of a tandem actuator, two control servalves, four pressure transducers, an LVDT transformer, and various input and feedback linkages that provide pitch and roll control for the aircraft.

The qualification requirements are essential because improper operation of the servocylinder could result in aircraft mission degradation or failure, potentially causing damage to the aircraft or injury to the pilot. The estimated cost to qualify an additional source is $5,000.00. The approved sources for overhaul/modification include Smiths Aerospace Actuation Systems in Duarte, CA, Moog Inc. in East Aurora, NY and Salt Lake City, UT, and Boeing in Long Beach, CA. The qualification documentation is set forth in the OC-ALC Source Approval Information Booklet, and the qualification requirement expires in 7 years.
