EASA AD 2019-0285
SUPERSEDED BY EASA AD 2021-0038
Summary
EASA Airworthiness Directive 2019-0285 is an airworthiness directive issued for Airbus Helicopters EC 175 B models. It mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the Airbus Helicopters EC 175 B Airworthiness Limitations Section Revision 014. The directive addresses recalculation of service life limits and replacement of certain parts to ensure continued airworthiness.
What Changed
This directive supersedes the previous Emergency AD 2017-0211-E and incorporates new and more restrictive maintenance tasks and limitations introduced in the latest Airworthiness Limitations Section. It requires recalculation of accumulated flight hours for specific parts, replacement of planet gears with a new part number, and updates to the approved Aircraft Maintenance Programme to include these changes.
Why It Matters
Compliance with EASA Airworthiness Directive 2019-0285 is critical for operators and maintenance organizations to prevent unsafe conditions caused by exceeding service life limits or missing updated maintenance requirements. It ensures that helicopters remain airworthy by enforcing mandatory inspections, part replacements, and maintenance tasks. Failure to comply could lead to unsafe operations and regulatory non-compliance.
What To Do
Operators must recalculate service life limits for specified parts before the next flight after 25 October 2017 and within 30 days of the directive's effective date. They must replace planet gears with the specified part number within 30 days and update their Aircraft Maintenance Programme within 12 months to incorporate the new limitations and tasks. Installation of non-serviceable parts or prohibited planet gears is not allowed from the effective date.
