This SAE Aerospae Recommended Practice (ARP) covers visible surface defects on aerospace hose assemblies which have been installed and are functioning within a working environment at the time of visual inspection. This document is intended to help those who are conducting periodic visual inspections of hose assemblies used in aerospace systems and ground servicing equipment to determine time for replacement by condition of hose assemblies at time of inspection. This practice is intended to augment existing procedures for replacement of hose assemblies based on service time. A constant surveillance of all hose assemblies for visible wear, defects, and/or damage shall be routine at all times of maintenance. When wear, defects, or damage to installed hose assemblies is detected, the hose assemblies shall be tagged or replaced in accordace with Section 4 of this document.
This specification covers the requirements for aircraft, hydraulic, self-sealing, quick disconnect couplings, for use in Type II hydraulic systems (-65 to +275 °F temperature range) as defined by AS5440.
This Aerospace Information Report (AIR) is written as a guide for the wording recommended for use, when applicable, in design and procurement specifications for tube fittings and tube assemblies, both for general aerospace fluid power applications and for specific applications.
This AIR is intended to describe and document a process presently in use for proof testing, which at the same time improves the fatigue life of 304 1/8 hard CRES and 3Al-2.5V CWSR titanium hydraulic tubing lines.
This document establishes the requirements for aircraft, hydraulic couplings, self-sealing one side only, for use in Type II hydraulic systems (-65 to +275 °F temperature range) as defined by MIL-H-5440. The purpose being to connect a hose or tube to a standard MS33656, MS33514, or MIL-F-85421, or MIL-F-85720 fitting, and to provide the self-sealing feature on the hose or tube side of the connection.
