What to do
Operators of Airbus Helicopters EC 175 B must amend the Rotorcraft Flight Manual and Master Minimum Equipment List before the next flight or before installing removable flotation parts. They must inspect the affected EFU parts within 50 flight hours or 30 days after the effective date and replace any defective units before further flight. Only serviceable EFU parts may be installed from the effective date onward.
Summary
EASA Airworthiness Directive 2018-0236-E is an emergency directive addressing Airbus Helicopters EC 175 B models equipped with specific Emergency Flotation Units (EFU) part numbers SE13876 and SE24251. It mandates inspection and possible replacement of the EFU due to a reported issue of unwanted inflation caused by contamination on the EFU's printed circuit board. The directive also requires temporary revisions to the Rotorcraft Flight Manual and Master Minimum Equipment List to prevent manual mode use of the flotation system.
What changed
This directive introduces immediate requirements for amending flight manuals and minimum equipment lists, conducting a one-time inspection of the EFU printed circuit board, and replacing affected units if defects are found. It also defines operational restrictions and installation conditions for the EFU parts to mitigate the risk of uncommanded inflation.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to uncommanded deployment of the emergency flotation system, potentially causing loss of helicopter control. Operators and maintenance teams must comply promptly to ensure continued airworthiness and safe operation of affected EC 175 B helicopters.
