EASA AD US-2020-18-16
NOT ADOPTED - EASA DECISION ATTACHED
Summary
The document titled 'NOT ADOPTED - EASA DECISION ATTACHED' is a final rule airworthiness directive issued by the Federal Aviation Administration (FAA) addressing certain Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. It mandates modifications to the fuel quantity indicating system (FQIS) to prevent ignition sources inside the center fuel tank caused by electrical faults. Optional actions are also provided for cargo-configured airplanes.
What Changed
This new FAA airworthiness directive requires operators of affected Boeing 767 models to modify the FQIS to eliminate potential ignition sources within the center fuel tank. The directive introduces specific corrective actions based on manufacturer fuel system reviews and includes optional measures for cargo airplanes. It does not amend or supersede previous directives but establishes new mandatory safety requirements.
Why It Matters
This directive is critical for aviation professionals as it addresses a significant safety risk involving potential fuel tank explosions due to electrical faults in the FQIS. Operators, maintenance organizations, and compliance teams must ensure these modifications are implemented to maintain airworthiness and regulatory compliance. Failure to comply could result in unsafe flight conditions and regulatory penalties.
What To Do
Affected operators must arrange for the required FQIS modifications on Boeing 767-200, -300, -300F, and -400ER airplanes by the effective date. They should obtain and follow Boeing service information and coordinate with maintenance providers to complete the work. The directive becomes effective on November 10, 2020, and compliance must be achieved by that date.
