Summary
EASA Airworthiness Directive 2021-0136 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A330 and A340 aeroplanes. It addresses the replacement of doghouse placards in the passenger cabin that provide door lock handling instructions. The directive applies to all manufacturer serial numbers of specified Airbus A330 and A340 models.
What Changed
This directive requires the removal of unclear and incomplete doghouse door lock instruction placards and their replacement with improved placards as specified in Airbus Service Bulletins. It also prohibits the installation of affected doghouse parts unless they have been modified according to the new instructions. This is a new regulation introduced to correct the handling instructions and improve safety.
Why It Matters
The unclear placard instructions could lead to incorrect operation of the doghouse door lock, potentially causing the latch to fail and block access to emergency equipment. This poses a safety risk to aircraft occupants during emergencies. Compliance ensures that operators maintain access to critical emergency equipment and meet regulatory airworthiness requirements.
What To Do
Operators of affected Airbus A330 and A340 aeroplanes must remove the existing placards and install the improved handling instruction placards within 12 months from 18 June 2021. Additionally, no affected doghouse parts may be installed on any aeroplane unless modified according to the directive. Compliance with the specified Airbus Service Bulletins is mandatory.
