EASA SIB 2012-03: Antonov An-26 Aeroplanes — Changes to Type Design, Airworthiness Limitations and Repairs

What to do

Operators of Antonov An-26 aeroplanes should verify if any lifetime extensions beyond the original approved limits have been applied and remove any parts that have reached or exceeded those limits. Before performing any modifications or repairs, stakeholders must confirm that EASA approval has been granted for those changes. No extended life limits from Issue 2 of the An-26 ICA should be used until EASA approval is obtained.

Summary

EASA Safety Information Bulletin 2012-03 addresses changes to the Antonov An-26 aeroplanes' type design, airworthiness limitations, and repair designs. It specifically applies to the Antonov An-26 series as listed in the Restricted Type Certificate Data Sheet EASA.IM.A.315. The bulletin informs operators about the status of life limit extensions and repair approvals related to the An-26 Instructions for Continued Airworthiness.

What changed

The bulletin highlights that Issue 2 of the An-26 Instructions for Continued Airworthiness, approved by the State Aviation Administration of Ukraine in June 2011, extends life limits for certain parts and the airframe. However, these extended life limits have not yet been approved by EASA, so they cannot be used by European-registered An-26 operators. Additionally, some type design and repair changes approved by the Ukrainian authority may be implemented without EASA approval under limited conditions.

Why it matters

This information is critical for aviation professionals managing An-26 aircraft in Europe because it clarifies which life limits and repair data are currently valid under EASA regulations. Operators and maintenance organizations must ensure compliance with the original life limits and verify EASA approval before applying any modifications or repairs. This helps maintain airworthiness and regulatory compliance, avoiding unauthorized use of extended life limits or unapproved repairs.
