Required actions
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2024-0139.
Unsafe condition
This AD was prompted by a report of a structural crack in the vertical attachment spar of the upper tail fin and fractures in its two front attachment screws. The FAA is issuing this AD to address cracking in the upper fin spar and fracturing of the front attachment screws. The unsafe condition, if not addressed, could result in in-flight separation of the upper part of the vertical fin and consequent loss of control of the helicopter.
Affected ADs
This AD replaces AD 2021-20-16, Amendment 39-21754 (86 FR 57550, dated October 18, 2021).
