What to do

Operators of affected CN-235 aeroplanes must replace components before exceeding their life limits and perform all maintenance tasks within specified intervals as detailed in the Airbus D&S CN-235 ALL issue R.

Summary

EASA Airworthiness Directive 2018-0134 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting EADS-CASA CN-235, CN-235-200, and CN-235-300 aeroplanes, excluding the CN-235-300 Maritime Patrol (SM01) configuration. This directive mandates compliance with the Airbus Defence and Space CN-235 Airworthiness Limitations List (ALL) issue R dated 20 March 2018 to ensure continued airworthiness. It requires operators to perform maintenance tasks and replace life-limited parts according to the specified limits and intervals.

What changed

EASA AD 2018-0134 introduces mandatory compliance with the updated Airbus D&S CN-235 ALL issue R, which includes new or revised airworthiness limitations and maintenance tasks. It requires operators to replace components before exceeding life limits and to revise their Aircraft Maintenance Programme (AMP) within 12 months to incorporate these updated requirements. This AD does not supersede any previous directives but establishes the current mandatory maintenance standards.

Why it matters

This directive is critical for aviation professionals as it ensures the continued airworthiness and safety of the CN-235 fleet by enforcing updated maintenance and life limitation requirements. Operators and maintenance organizations must comply to avoid unsafe conditions that could arise from neglecting these instructions. Compliance also fulfills regulatory obligations under EU aviation safety regulations, preventing operational restrictions or penalties.
