AD 2021-04-15 Airworthiness Directives; Airbus Helicopters
Models named: AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, AS350B3. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus Helicopters specified in paragraph (c)(1) and (2) of this AD, certificated in any category. (1) Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters, all serial numbers. (2) Model AS350B3 helicopters, all serial numbers except those that have embodied Modification 07.3148 in production, or Eurocopter AS350 Service Bulletin 55.00.14 (any revision) in service.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2020-0186, dated August 20, 2020 (EASA AD 2020-0186).
Unsafe condition
This AD was prompted by a report that, during an unscheduled post-flight inspection of the tail cone area of an Airbus Helicopters Model AS355NP helicopter, a crack was found in the spar of the upper fin and fractures were found in the two front attachment screws. The FAA is issuing this AD to address cracking in the spar of the upper part of the vertical fin and fractures in the front attachment screws. This condition could lead to in-flight separation of the upper part of the vertical fin, resulting in loss of control of the helicopter.
Affected ADs
None.
