What to do
Operators must inspect the fuel filter bowls on both sides of the AS 332 and EC 225 helicopters within 55 flight hours or 30 days from 22 May 2023, whichever occurs first. If any cracks or discrepancies are found, the affected fuel filter must be replaced with a serviceable part before the next flight. Only serviceable fuel filter parts may be installed on these helicopters from the effective date onward.
Summary
EASA Airworthiness Directive 2023-0095 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Helicopters AS 332 (C, C1, L, L1, L2) and EC 225 LP models. It addresses a safety concern related to cracks found on the right-hand side fuel filter bowl, which could lead to dual engine shutdown and reduced helicopter control. The directive mandates inspection and possible replacement of specific fuel filter parts to ensure continued airworthiness.
What changed
This directive introduces a one-time inspection requirement for fuel filter bowls with Manufacturer Part Number 4020P25-5 on the affected helicopter models. It requires operators to inspect both right-hand and left-hand side fuel filters within 55 flight hours or 30 days and replace any parts found with defects before further flight. The directive also permits installation of only serviceable fuel filter parts from the effective date.
Why it matters
This airworthiness directive is critical for aviation professionals as it addresses a potential unsafe condition that could cause in-flight dual engine shutdown, severely impacting flight safety. Operators and maintenance organizations must comply to prevent fuel filter bowl cracking caused by over-torquing during maintenance. Compliance ensures continued safe operation and regulatory adherence for affected Airbus Helicopters models.
