Overview
EN 4424:2006 - Aerospace series - specifies dimensional, material and load characteristics for adjustable rod-ends, single fork, with threaded shank manufactured in titanium alloys for use on flight control rods and aircraft structural rods. The standard defines an engagement depth of 1.5 × thread diameter and includes identification and locking groove provisions to ensure correct installation and traceability.
Key topics and requirements
- Configuration: single fork rod-end with a threaded shank and a circumferential groove to identify engagement; a longitudinal groove is optional for locking purposes.
- Engagement: threaded shank engagement depth = 1.5 × thread diameter (as a fundamental design requirement).
- Material: titanium alloy in accordance with referenced aerospace material documents (EN 3315, EN 3353, TR 3775); whole rod-end to have R > 830 MPa where specified.
- Threads and dimensions:
- External threads per ISO 3353 (aerospace threads).
- Groove diameter limits referenced to ISO 5855-2.
- Detailed dimensions, masses and ultimate loads are given in the standard’s Table 1 and conform to the Figure 1 configuration.
- Note: “l” is defined as the minimum length of engaged thread and includes thickness of lock washers and nut height.
- Surface & marking:
- Circumferential groove and any longitudinal groove shall be painted red (identification/locking).
- Each rod-end and its packaging must carry an indelible identity block marking as defined in Clause 4 (example designation: ROD-END EN4424L08K).
- Technical specification: additional requirements refer to EN 2601 (fork ends, adjustable - technical specification).
Applications and who uses it
- Design and manufacturing of flight control linkages, actuation rods and aircraft structural rods.
- Procurement and quality assurance for aerospace component suppliers, OEMs, and MRO organizations requiring standardized rod-ends in titanium alloys.
- Structural and systems engineers, certification bodies and maintenance engineers who need to verify dimensions, material, thread engagement and load capabilities for safety-critical control components.
