EASA AD 2014-0236R1
Lights — Emergency Lighting Rotorcraft Flight Manual Amendment / Operational Procedure
Summary
EASA Airworthiness Directive 2014-0236R1 is an amendment addressing emergency lighting battery issues on Airbus Helicopters SA 365, AS 365, and EC 155 models. It applies to helicopters equipped with specific Cobham or Air Precision emergency lighting batteries and requires amendments to the Rotorcraft Flight Manual and operational procedures to ensure battery functionality. The directive aims to maintain emergency lighting operation for at least 10 minutes under critical conditions.
What Changed
This revision of EASA AD 2014-0236 recognizes the optional embodiment of Airbus Helicopters modification 0724C44 for AS 365 and SA 365 helicopters as an acceptable compliance method. It updates compliance options by allowing removal of the Rotorcraft Flight Manual amendment after modification and clarifies operational procedures for emergency lighting battery maintenance in low temperatures.
Why It Matters
This directive is crucial for aviation professionals to ensure emergency lighting batteries provide reliable power during emergencies, especially in low temperature conditions. Compliance prevents rapid battery self-discharge that could hinder safe evacuation, thereby enhancing occupant safety. Operators and maintenance teams must follow updated procedures to maintain airworthiness and regulatory compliance.
What To Do
Operators must amend the Rotorcraft Flight Manual within 30 days after 11 November 2014 by inserting specified Airbus Helicopters Alert Service Bulletin appendices and perform daily functional checks of the emergency lighting battery before the first flight. Alternatively, for AS 365 and SA 365 helicopters, embodiment of modification 0724C44 as per Airbus Helicopters Service Bulletin AS365-33.00.26 removes the need for manual RFM amendments and daily checks.
