AD 2021-20-05 Airworthiness Directives; Leonardo S.p.a. Helicopters
Models named: AW189. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Leonardo S.p.a. Model AW189 helicopters, certificated in any category, with an affected emergency flotation system (EFS) assembly as defined in European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD 2018-0279, dated December 14, 2018 (EASA AD 2018-0279).
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 2018-0279.
Unsafe condition
This AD was prompted by a report of an incorrect connection of the inflation hoses to the tee manifolds of the inflation line on the EFS assembly. The FAA is issuing this AD to detect incorrect installation of the inflation hoses on the EFS assembly. The unsafe condition, if not addressed, could result in partial inflation of the flotation bags in a ditching event, preventing a timely egress from the helicopter and consequent injury to the helicopter occupants.
Affected ADs
None.
