What to do
Operators of affected Airbus A330 and A340 aircraft must replace any Nose Landing Gear retraction actuator before it exceeds the specified time between overhaul, with a possible 3-month tolerance for synchronization with other maintenance tasks. For certain A340-541/542/642/643 models, specific postponement allowances apply based on the part's age at the effective date. Only serviceable parts may be installed after the directive's effective date, and replacements must follow Airbus service bulletins and maintenance manual instructions.
Summary
EASA Airworthiness Directive PAD No. 26-100 is a proposed directive addressing the replacement of Nose Landing Gear (NLG) retraction actuators on Airbus A330 and A340 aircraft models. It applies to all manufacturer serial numbers of specified A330 and A340 variants, including the extended applicability to A340-541, A340-542, A340-642, and A340-643 models. The directive aims to ensure continued airworthiness by mandating replacement of affected parts before exceeding specified time between overhaul intervals.
What changed
This proposed directive supersedes EASA AD 2012-0034R1 and extends the applicability to include additional A340 models (A3456 series). It retains previous requirements for NLG retraction actuator replacement but introduces a 3-month tolerance for compliance with the time between overhaul limits. The directive also clarifies installation conditions for serviceable parts and updates references to the latest Airbus Maintenance Review Board Reports.
Why it matters
This directive is critical for aviation professionals as it addresses a safety issue where corrosion and mechanical failure of the NLG retraction actuator could lead to nose gear collapse after touchdown. Operators and maintenance organizations must ensure timely replacement of affected parts to prevent in-flight turnbacks and potential damage or injury. Compliance with updated maintenance instructions and schedules is essential to maintain aircraft safety and regulatory conformity.
