EASA AD 2026-0107
Navigation – Radio Altimeter and Ground Proximity System Antennas – Modification
Summary
EASA Airworthiness Directive 2026-0107 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Defence and Space C-295 aeroplanes with manufacturer serial numbers 188, 189, and 191. The directive mandates modifications to the radio altimeter and ground proximity system antenna installations to ensure structural integrity. This AD applies specifically to these aircraft models and requires compliance with Airbus Defence and Space service bulletins SB-295-34-0091C and SB-295-34-0092C.
What Changed
This new airworthiness directive introduces mandatory modifications to the radio altimeter and ground proximity system antenna supports on specified C-295 aeroplanes. It addresses the issue of removed countersunk rivets during antenna installation, which could compromise structural integrity if left uncorrected. The directive requires operators to follow specific Airbus service bulletins to restore proper antenna support installation.
Why It Matters
This directive is critical for aviation professionals because it ensures the continued structural safety of affected C-295 aircraft by correcting potentially unsafe antenna installations. Operators and maintenance organizations must comply to avoid structural failures that could impact flight safety. Compliance also ensures adherence to European aviation regulations and maintains the aircraft's airworthiness status.
What To Do
Operators of affected C-295 aeroplanes must modify the radio altimeter antenna installation before the aircraft accumulates 2,600 flight cycles and the ground proximity system antenna installation before 3,100 flight cycles. These modifications must be performed following the instructions in Airbus Defence and Space service bulletins SB-295-34-0091C and SB-295-34-0092C, respectively. Alternative methods of compliance may be approved by EASA if properly substantiated.
