Overview
EN 4460:2005 is a European standard developed by CEN for aerospace applications, focusing on the installation and removal procedures of studs made from titanium alloy TI-P64001. These studs feature a serrated locking ring composed of corrosion-resisting steel as specified in EN 4421. The standard ensures that aerospace components utilizing these studs maintain high reliability, corrosion resistance, and structural integrity critical to the aviation industry.
This standard provides detailed guidelines on installation hole preparation, inspection protocols, tools and methods for installation, as well as procedures for stud removal and replacement. Compliance with EN 4460:2005 supports the longevity and safety of aerospace assemblies where titanium alloy studs are used.
Key Topics
Scope and Applicability
- Applies to studs with serrated locking rings in corrosion-resistant steel.
- Specifically covers installation and removal procedures to maintain compliance with aerospace safety standards.
Installation Hole Specifications
- Defines the installation hole characteristics, including the requirement for spotfacing in aluminum and magnesium alloys.
- Describes drilling and broaching techniques necessary for creating the serrated profile that ensures secure stud installation.
Inspection Requirements
- Prior to installation, installation holes, counterbores, and serrations must be free from burrs, grease, oil, or foreign objects.
- Studs must be clean and free of protective grease, and studs installed in aluminum components require an anti-corrosion compound to prevent electrolytic damage.
Installation Tools and Techniques
- Outlines principles for tool use without mandating specific designs, emphasizing prevention of damage to studs or components.
- Threads must be coated with oil before installation, and a shim is used when screwing studs into preserrated holes to avoid premature locking.
- Installation involves hand screwing followed by applying continuous axial thrust to fully seat the locking ring.
Stud Removal and Replacement
- Stud removal requires destruction of the locking ring by cutting the stud and drilling for extraction.
- Detailed dimensions and step-by-step removal procedures are provided.
- Replacement procedures must follow repair instructions developed by the Manufacturing Design Office (MDO), as oversized repair parts are not permitted.
Applications
Aerospace Manufacturing
- Critical for assembly and maintenance of aerospace components requiring high-strength, corrosion-resistant fasteners.
Aircraft Structural Assembly
- Ensures the reliable mounting of components where titanium alloy studs provide necessary strength-to-weight performance.
Maintenance and Repair Operations
- Standardizes procedures for safe removal and replacement of studs during repair or overhaul, minimizing component damage.
Corrosion Resistance Enhancement
- Addresses protection against electrolytic corrosion when studs are installed in aluminum or magnesium alloy structures.
