Overview
ISO 2026:2020 is an international standard specifying the precise dimensions and minimum clearances for connections used in starting aircraft engines by air. Developed by the International Organization for Standardization (ISO), this second edition ensures the interchangeability of air start connectors and adaptors across global aviation systems. By defining standard sizes and tolerances for these connections, ISO 2026:2020 facilitates safe, efficient, and seamless ground support operations, which are critical during aircraft engine start-up procedures.
This standard applies specifically to the physical dimensions of the connectors on aircraft and the minimum clearance requirements around them, ensuring adequate access for ground equipment.
Key Topics
Connection Dimensions and Tolerances: ISO 2026:2020 provides detailed measurements, including maximum and minimum diameters, lengths, and gauge points for connectors. This ensures uniformity in the manufacture of air start connectors to enable global compatibility.
Minimum Clearance Specifications: The standard defines the spatial requirements surrounding the connection points on aircraft. This clearance is essential to allow ground personnel to safely and efficiently attach adaptors, reducing risk and operational downtime.
Interchangeability: By adhering to these specifications, different manufacturers and operators can rely on compatibility, facilitating international operations and maintenance consistency.
Compliance and Revision: The document formally replaces the original 1974 edition, introducing minor revisions to align with current ISO and IEC editorial directives.
Applications
ISO 2026:2020 is crucial for the aerospace industry, particularly for:
Aircraft Manufacturers: Ensuring engine starting systems comply with international dimensional standards for air connections to allow reliable ground support.
Ground Support Equipment Providers: Designing adaptors and support tools that fit standardized connection interfaces across various aircraft models worldwide.
Maintenance and Service Operations: Enhancing safety and efficiency in engine start procedures by guaranteeing the proper fit of air start connectors and allowing sufficient clearance for handling equipment.
Regulatory Compliance: Supporting airlines and maintenance organizations to meet industry safety and interoperability requirements.
Related Standards
ISO/IEC Directives: Provides guidelines on drafting and applying international standards relevant for procedural consistency.
Aerospace Equipment Standards: Other ISO standards related to aircraft ground support, air cargo loading, and engine maintenance.
IEC Electropedia & ISO OBP: Terminology databases that complement standardization efforts by providing clear definitions related to aerospace and electrotechnical components.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
