Fuel — Air No Fuel Valves — Replacement
Summary
EASA Airworthiness Directive 2019-0289 is an airworthiness directive issued for Airbus Helicopters EC 175 B models. It addresses a manufacturing defect in air no fuel valves with Part Number 510396-2, which may cause fuel leakage and increase the risk of post-impact fire following a hard landing.
What Changed
This new directive requires the replacement of affected air no fuel valves (P/N 510396-2) with a more robust serviceable part (P/N 510396-3). It also prohibits the installation or reinstallation of the affected parts on any EC 175 B helicopter from the effective date.
Why It Matters
This directive is critical for aviation professionals to ensure the continued airworthiness and safety of EC 175 B helicopters. Operators and maintenance teams must address the fuel valve defect to prevent potential fuel leaks and reduce the risk of fire, thereby protecting both the aircraft and occupants.
What To Do
Operators of EC 175 B helicopters with affected parts must replace these air no fuel valves within 880 flight hours or 24 months from 13 December 2019, whichever occurs first. Additionally, no affected parts may be installed on any helicopter after the effective date of this directive.
