EASA AD 2019-0102
SUPERSEDED BY EASA AD 2019-0287
Summary
EASA Airworthiness Directive 2019-0102 is an airworthiness directive affecting Airbus Helicopters EC 225 LP models equipped with emergency life rafts installed in multi-purpose sponsons with modification 07 25749. The directive addresses issues with the life raft release bellcranks, specifically part numbers 332A41-4396-20 and 332A41-4396-21, which may jam due to foreign coating material or corrosion. It mandates inspections, cleaning, lubrication, and eventual replacement of affected parts to ensure proper life raft deployment during emergencies.
What Changed
EASA AD 2019-0102 supersedes the previous AD 2016-0200 and retains its cleaning and lubrication requirements while introducing a mandatory replacement of affected bellcranks with improved serviceable parts within 12 months. It also prohibits the installation of affected parts going forward, making the replacement a terminating action for repetitive maintenance tasks.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk that could prevent life rafts from deploying in emergencies, potentially endangering occupants. Operators and maintenance organizations must comply to ensure continued airworthiness and regulatory compliance, avoiding operational disruptions and enhancing passenger safety.
What To Do
Operators of affected EC 225 LP helicopters must perform cleaning and lubrication of the life raft inflation cylinder percussion bellcranks every six months if the helicopter has affected parts installed. Any discrepancies found during inspections require immediate corrective action before flight. Additionally, within 12 months of the directive's effective date, all affected bellcranks must be replaced with serviceable parts as per the specified service bulletin instructions.
