What to do
Operators must implement the airworthiness limitations and maintenance tasks specified in the ALS starting from 4 August 2017. They must revise their approved Aircraft Maintenance Programmes within 12 months of that date to incorporate these requirements. Any discrepancies found during inspections must be corrected within specified compliance times or before the next flight if no time is given.
Summary
EASA Airworthiness Directive 2017-0124R1 is an amendment applicable to Leonardo S.p.A. AB139 and AW139 helicopters. It mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the latest issue of the Leonardo Helicopters Maintenance Manual 39-A-AMPI-00-P Chapter IV. This directive ensures continued airworthiness by enforcing life limits and inspection requirements for these helicopter models.
What changed
EASA Airworthiness Directive 2017-0124R1 revises the original AD 2017-0124 by confirming that the requirements of EASA AD 2006-0357R2 are also superseded. It incorporates new and more restrictive airworthiness limitations and maintenance tasks from issue 8 of the Maintenance Manual. Additionally, it consolidates previous AD requirements into a single approved Airworthiness Limitation Section (ALS).
Why it matters
This directive is critical for operators and maintenance organizations to ensure the safe operation of AB139 and AW139 helicopters by enforcing mandatory maintenance and inspection tasks. Compliance prevents unsafe conditions caused by failure to adhere to updated life limits and inspection intervals. It also streamlines maintenance programs by consolidating multiple AD requirements into one approved document.
