What to do
Operators must inspect affected power turbine discs before reaching specified cycle limits or at the next engine shop visit, replacing any damaged or non-conforming parts before further flight. Replacement deadlines vary by engine group, ranging from immediate replacement at next shop visit to within 60 months. Installation of affected parts is prohibited after inspection or replacement as specified.
Summary
EASA Airworthiness Directive 2019-0061 is an airworthiness directive addressing certain GE Aviation Czech M601 series engines installed on various aircraft including the Aircraft Industries L-410 series, Air Tractor AT series, Allied Ag Cat G-164 series, PZL-106 Kruk, RUAG Do 28 series, and Thrush S-2R series. The directive mandates inspection and potential replacement of power turbine discs with specific part numbers and serial numbers to prevent failure due to damage or non-conforming geometry.
What changed
This directive supersedes previous EASA ADs 2016-0025-E and 2017-0100, consolidating and updating inspection and replacement requirements for affected power turbine discs. It introduces new affected part numbers and serial numbers, updates risk assessments, and extends compliance timelines for replacement and inspection actions.
Why it matters
Compliance with EASA AD 2019-0061 is critical to prevent power turbine disc failure, which could lead to the release of high-energy debris and potential loss of aircraft control. Operators, maintenance organizations, and compliance teams must ensure timely inspections and replacements to maintain aircraft airworthiness and safety.
