What to do
Operators of EC 175 B helicopters must replace the affected aluminum scuppers with the redesigned fire-proof parts within 800 flight hours or 12 months from the effective date of the directive, whichever occurs first. After modification, reinstalling the affected aluminum parts is prohibited. Maintenance should follow the instructions in Airbus Helicopters Alert Service Bulletin EC175-53-48-0001.
Summary
EASA Airworthiness Directive 26-008 is a proposed directive addressing Airbus Helicopters EC 175 B models. It mandates modification of the fuselage engine drain system scuppers to replace non-fire-proof aluminum parts with redesigned fire-proof stainless steel components. This directive applies to all EC 175 B helicopters except those already modified with Airbus Helicopters modification 99A04406.
What changed
This new directive introduces a requirement to replace the left-hand and right-hand engine drain system scuppers made of light aluminum alloy with fire-proof stainless steel parts. The modification aims to prevent the risk of scupper ignition and fire propagation in the engine compartment. It also prohibits reinstalling the affected aluminum parts after the modification.
Why it matters
This directive is critical for aviation professionals because it addresses a potential safety hazard where engine drain system scuppers could ignite during an engine fire, potentially leading to an uncontained fire and loss of the helicopter. Operators and maintenance teams must ensure compliance to enhance fire safety and prevent catastrophic damage. Compliance also ensures adherence to EASA continuing airworthiness requirements.
