What to do
Operators of EC 175 B helicopters must identify if their aircraft have affected shock absorbers installed and replace them with serviceable parts before 20,000 landing cycles or within 42 months from 30 December 2019, whichever is earlier. Additionally, no affected parts may be installed on any helicopter from the effective date onward. Compliance with Airbus Helicopters Alert Service Bulletin EC175-32A002 Revision 0 is required.
Summary
EASA Airworthiness Directive 2019-0303 is an airworthiness directive issued for Airbus Helicopters EC 175 B models. It addresses inspection and replacement requirements for specific left-hand and right-hand main landing gear shock absorbers identified by certain part and serial numbers. The directive aims to ensure continued airworthiness by mandating removal and replacement of affected parts to prevent landing gear failure.
What changed
This new airworthiness directive introduces mandatory replacement of certain main landing gear shock absorbers on EC 175 B helicopters due to a manufacturing non-conformity that reduces their fatigue life. It prohibits installation of affected parts on any helicopter and requires replacement before exceeding 20,000 landing cycles or within 42 months from the effective date, whichever occurs first.
Why it matters
This directive is critical for aviation professionals because it addresses a potential safety risk involving premature failure of main landing gear shock absorbers, which could lead to loss of landing gear function and possible injury or damage. Operators and maintenance organizations must comply to maintain aircraft airworthiness and avoid operational disruptions or safety incidents.
