FAA Proposes Fuel Hose Inspections for Airbus A220 Aircraft

The Federal Aviation Administration (FAA) has put forward a proposal that could affect certain Airbus A220 aircraft operated by Delta Air Lines, Breeze Airways, and JetBlue. This proposed action focuses on the fuel hose lines, aiming to prevent a potential fire risk. The FAA’s plan involves inspections to ensure these fuel lines are installed correctly, preventing them from rubbing against other parts.

This measure is being presented as a preventive step rather than an immediate safety crisis. The agency is seeking public input on the proposal, with comments due by October 19, 2026. The FAA’s goal is to address a potential issue stemming from a change in the manufacturing process that may not have been fully reflected in the installation instructions.

Understanding the FAA’s Proposal

The FAA’s proposal targets 13 specific Airbus A220-100 and A220-300 aircraft registered in the U.S. The concern centers on the motive-flow flexible fuel line assemblies. If a fuel hose is installed in a twisted position, it could rub against nearby materials during flight. This friction could wear down the hose over time, potentially leading to a fuel leak.

The agency has identified that a mismatch between a production configuration change and the official installation procedure might be the root cause. This could result in the flexible line being twisted during installation, causing it to press against its protective shroud. Repeated contact over time could lead to wear and the possibility of fuel escaping near electrical connectors, which presents a fire hazard.

Scope of the Proposed Inspections

The FAA’s proposed directive requires inspections of the affected fuel hose assemblies. It is important to note that this is not a grounding order, meaning the aircraft are not being immediately taken out of service. The proposal aims to address a specific set of aircraft, and not all A220s operated by the mentioned airlines are included.

This new proposal would update and expand upon a previous directive from 2021. By including four additional aircraft, the total number of U.S.-registered A220s subject to inspection would rise to 13. Delta Air Lines, Breeze Airways, and JetBlue are the carriers operating these specific aircraft.

Estimated Costs and Impact

The FAA estimates that conducting these inspections will require approximately 10 labor hours per aircraft. Based on their standard labor rates, the cost for each inspection is projected to be around $850. This cost is for the inspection itself.

If an inspection reveals an issue that requires a pylon component to be replaced, the estimated cost for that repair is higher, at $10,005 per pylon. However, this replacement cost would only apply if the inspection identifies a problem necessitating such a repair. The FAA views this as a preventive maintenance action to ensure continued safety.

Airline Response and Public Comment

Delta Air Lines has stated its commitment to complying with all regulatory safety requirements. A spokesperson for Delta mentioned that safety is their top priority and that they fully adhere to directives from aviation regulators.

The proposed rulemaking process is currently open for public comment. Interested parties, including airlines, manufacturers, and the general public, have until October 19, 2026, to submit their feedback to the FAA. Until the agency finalizes the rule, the inspection requirement remains a proposal. The FAA will consider these comments before making a final decision on the directive.
