What to do
Operators of affected Airbus A330 and A340 aeroplanes must identify if affected FFAs are installed and perform tests of the free fall system within specified compliance times, followed by repetitive tests at defined intervals. If any FFA fails the test, it must be replaced with a serviceable unit before the next flight. Installation of affected FFAs is prohibited from the effective date, and replacement of all affected FFAs terminates the need for repetitive testing.
Summary
EASA Airworthiness Directive 2019-0164 is an airworthiness directive addressing Airbus A330 and A340 aeroplanes equipped with free fall actuators (FFA) part number AR02404. It mandates inspection and testing of affected FFAs installed on nose, main, and center landing gears to prevent failure of landing gear extension by free fall. The directive applies to all manufacturer serial numbers of specified Airbus A330 and A340 models.
What changed
EASA Airworthiness Directive 2019-0164 supersedes AD 2019-0063 and expands the list of affected FFAs by including units manufactured in additional years. It also amends the inspection intervals for repetitive testing of the free fall actuators and retains the original requirements with updated compliance times and corrective actions.
Why it matters
This directive is critical for aviation professionals because failure of the free fall actuator can prevent landing gear extension by free fall, potentially leading to loss of control during landing and causing damage or injury. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The directive also provides clear instructions for inspections, testing, and replacement to mitigate the risk.
