Overview
EN 2569:1991 - Aerospace series - Control cable fittings and turnbarrels - Technical specification is a CEN standard that defines the required characteristics and inspection/testing requirements for control cable fittings used in aerospace applications. The standard covers end fittings swaged onto control cables, cable turnbarrel components, and complete cable turnbarrel assemblies. EN 2569 was later adopted nationally (e.g., SIST EN 2569:2001), confirming its use across CEN members.
Key topics and requirements
EN 2569 focuses on the following technical areas:
- Required characteristics for fittings and turnbarrels, including dimensional and functional attributes expected for aerospace control systems.
- Qualification inspections that demonstrate components meet design and performance expectations before production or introduction to service.
- Acceptance inspections and tests used to verify production batches and assembled units conform to the specification.
- Coverage of three product groups:
- End fittings swaged onto control cables
- Cable turnbarrel components
- Cable turnbarrel assemblies
- Typical test and inspection categories referenced in the standard include dimensional checks, material and workmanship assessments, and functional/assembly verification (qualification and acceptance level). Note: EN 2569 specifies the need for inspections and tests rather than prescribing unrelated or non-applicable procedures.
Applications
EN 2569 is intended for use where reliable control cable terminations and adjusters are critical to flight safety and performance. Typical practical applications:
- Flight control cable assemblies in fixed-wing and rotary-wing aircraft
- Primary and secondary control systems where swaged end fittings and turnbarrels provide termination and adjustment
- Manufacture, procurement and repair of aerospace cable assemblies requiring standardized qualification and acceptance criteria
- Maintenance, overhaul and continuing airworthiness organizations validating replacement components
Who should use this standard
- Aerospace design and systems engineers specifying control cable terminations
- Manufacturers and suppliers of cable end fittings, swaging services, and turnbarrel components
- Quality assurance and inspection teams performing qualification and acceptance testing
- Maintenance, repair, and overhaul (MRO) organizations and procurement specialists ensuring compliant parts
Related standards
EN 2569 is part of the aerospace standards landscape for control cables and fasteners. For complete compliance and interoperability, users often consult other national or international standards and CEN documents that address cable materials, swaging processes and fastener performance.
