FAA Airworthiness Directive: Airbus Canada BD-500 Series Airplane Lavatory Electrical Harness Inspection
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The Federal Aviation Administration (FAA) has issued a new Airworthiness Directive (AD) targeting specific Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The directive was triggered by a production-line discovery that electrical system harnesses in lavatory A were installed with reduced bend radii, improper securing, and insufficient clearance from an oxygen supply line — all of which constitute deviations from airworthiness standards. The unsafe condition identified poses a risk of chafing or electrical damage in close proximity to an oxygen supply line, which could potentially lead to a fire hazard. To address this, the AD mandates a physical inspection of the sleeve and electrical harness in lavatory A for signs of chafing damage and incorrect installation. Depending on inspection findings, operators must carry out applicable on-condition corrective actions to bring affected components into compliance. The directive applies to aircraft whose type certificate was previously held by C Series Aircraft Limited Partnership (CSALP) and Bombardier, Inc., now under Airbus Canada.

Key Changes
- New AD issued for Airbus Canada BD-500-1A10 and BD-500-1A11 airplanes with production-line electrical harness defects in lavatory A
- Operators must inspect the sleeve and electrical harness in lavatory A for chafing damage and incorrect installation
- Root cause: electrical harnesses had reduced bend radii, were improperly secured, and lacked required clearance from the oxygen supply line

Obligations
What this law requires
Inspect the electrical system harness sleeve in lavatory A for signs of chafing damage on all affected aircraft
Inspect the electrical system harness installation in lavatory A to identify incorrect installation deviations from airworthiness standards
Verify clearance between electrical harness and oxygen supply line in lavatory A meets required standards
Execute applicable on-condition corrective actions to bring non-compliant electrical harness components into compliance with airworthiness standards based on inspection findings
Ensure electrical harness bend radii in lavatory A meet design specifications and are not reduced below acceptable tolerances
