SUPERSEDED BY EASA AD 2019-0159
Summary
EASA Airworthiness Directive 2018-0215 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all Airbus A380-841, A380-842, and A380-861 aeroplanes. It addresses a fuel quantity indication system issue related to incorrect fuel on board readings caused by a faulty refuel isolation valve position sensor. The directive mandates amendments to the Airbus A380 Aircraft Flight Manual to include procedures for cross-checking fuel quantity indications after refueling.
What Changed
This directive requires the incorporation of Airbus A380 Aircraft Flight Manual Temporary Revision 205 issue 1, which introduces a procedure to compare the indicated fuel on board after refueling with the sum of the initial fuel on board plus the fuel uplifted. It establishes a quantified tolerance for this cross-check to detect discrepancies caused by sensor contamination. This action is considered interim and may be followed by further directives.
Why It Matters
This directive is critical for aviation professionals as it prevents undetected fuel measurement errors that could lead to insufficient fuel supply to all engines, potentially compromising aircraft control. Operators and maintenance teams must ensure compliance to maintain aircraft safety and regulatory conformity. The amendment enhances fuel system reliability and supports accurate fuel management during pre-flight checks.
What To Do
Operators of Airbus A380-841, A380-842, and A380-861 aircraft must amend the Aircraft Flight Manual within 30 days of the directive's effective date to incorporate the specified temporary revision. Flight crews must be informed of the changes and operate the aircraft accordingly. Using later approved revisions that include the temporary revision is also acceptable for compliance.
