What to do
Operators must amend the Rotorcraft Flight Manual and Master Minimum Equipment List within three months of the effective date or concurrently with modification. Helicopters must be modified by replacing affected EFUs with serviceable parts within three months, followed by operational checks as specified in the Airbus Helicopters Alert Service Bulletin EC175-25A030.
Summary
EASA Airworthiness Directive 2019-0118 is an airworthiness directive affecting Airbus Helicopters EC175 B models. It addresses issues related to the Emergency Flotation Unit (EFU), specifically parts with manufacturer part numbers SE13876 and SE24251, requiring updates to the Rotorcraft Flight Manual and Master Minimum Equipment List.
What changed
This directive supersedes Emergency AD 2018-0236-E and mandates replacement of affected EFUs with improved serviceable parts (MP/N SE27276). It also requires amendments to the Rotorcraft Flight Manual and Master Minimum Equipment List, and introduces post-modification operational checks of the emergency flotation system.
Why it matters
The directive prevents un-commanded inflation of the emergency flotation system, which could lead to loss of helicopter control if deployed at unsafe speeds. Compliance ensures continued airworthiness and safety, reducing risk of accidents related to EFU malfunction for operators and maintenance organizations.
