Airline Rejected Your Technical Fault Claim? How To Reply

If the airline refused compensation because your delay was caused by a technical fault, do not stop at the first rejection. Under EU261 and UK261, a technical problem is not automatically an extraordinary circumstance. The next step is to ask the airline to prove its defence.

Quick Answer

A rejected technical fault claim is often worth challenging if the airline gave only a vague explanation.

Ask for the exact defect, when it was discovered, why it was outside normal airline operations, and what reasonable measures were taken. If the airline cannot answer those points, its rejection may be weak.

Your reply should be practical, not emotional. The strongest second letter is a short evidence request that makes the airline explain the technical fault instead of hiding behind a label.

Why Airlines Reject Technical Fault Claims

Technical faults are expensive for airlines because many passengers on the same flight may qualify for fixed compensation. A full aircraft delayed over three hours can create a large payout, so airlines often test whether passengers will accept the first refusal.

The rejection usually says the fault was “unexpected”, “safety-related”, or an “extraordinary circumstance”. Those words are not enough by themselves. Unexpected does not automatically mean extraordinary, and safety checks are part of normal airline operations.

The useful question is narrower: was the fault part of ordinary aircraft operation and maintenance, or was it caused by something genuinely outside the airline's control, such as a regulator grounding an aircraft type?

First Checks Before You Reply

Was the arrival delay 3+ hours?

Use arrival time at the final destination, not departure delay. For connected journeys, check the final arrival if the flights were under one booking.

Was the route covered?

EU261 covers EU departures and EU arrivals on EU airlines. UK261 covers UK departures and many UK-bound flights on UK or EU carriers.

Is the claim still within time?

Deadlines vary by country. Check the limitation period before investing time in a second letter.

Did the airline give a real reason?

A reply that only says "technical issue" or "operational reasons" should be challenged with a request for specific evidence.

Evidence To Request From The Airline

Your second letter should ask for evidence in a structured way. This makes it harder for the airline to rely on a generic refusal.

RequestWhy it matters
Exact technical defectA vague phrase such as "technical issue" does not show whether the fault was routine, maintenance-related, or genuinely outside normal operations.
When the fault was discoveredA defect found during normal turnaround, inspection, or pre-flight checks often points to ordinary operational risk.
Maintenance or engineering record summaryYou are not asking for confidential manuals. You are asking the airline to prove the basis of its refusal.
Manufacturer or regulator noticeIf the airline claims a hidden manufacturing defect or fleet-wide safety issue, ask for the notice that supports that claim.
Reasonable measures takenEven if there was a real technical problem, the airline should explain whether it considered a spare aircraft, crew swap, re-routing, or earlier repair options.

How To Structure Your Reply

1

Restate the claim clearly

Include booking reference, flight number, date, route, scheduled arrival, actual arrival, and the compensation amount you believe is due.

2

Quote their rejection reason

Use the airline's exact wording. If they only said "technical fault" or "extraordinary circumstances", say that the explanation is too general to assess.

3

Ask them to prove the defence

State that the airline bears the burden of showing the event was extraordinary and that all reasonable measures were taken.

4

Cite technical-fault case law

Refer to Wallentin-Hermann v Alitalia and Van der Lans v KLM as examples of courts treating routine technical faults as part of normal airline operations.

5

Set a response deadline

Ask for a substantive reply within 14 to 21 days, then say you will escalate to ADR, the national enforcement body, or small claims if the refusal is maintained.

Useful wording angle

“Please identify the specific technical defect and explain why it was not inherent in the normal operation of an air carrier. Please also confirm what reasonable measures were taken to avoid or reduce the delay.”

Where To Escalate If The Airline Still Refuses

If the airline gives no evidence, repeats the same generic wording, or ignores your deadline, escalation is the next step. The right route depends on the airline, the departure country, and whether the airline belongs to an ADR scheme.

United Kingdom

CEDR or AviationADR for participating airlines; otherwise the Civil Aviation Authority passenger advice route may help direct the complaint.

Germany

SOP handles many airline disputes and can review technical-fault refusals when the airline participates.

France

Use the airline complaint route first, then the relevant mediator or national enforcement channel if unresolved.

Other EU countries

Use the national enforcement body or the ADR body named by the airline in its final response.

Mistakes To Avoid

!

Do not accept "technical fault" as a complete explanation.

!

Do not send a long emotional complaint when a short evidence request would be stronger.

!

Do not ignore the claim deadline for the country connected to your claim.

!

Do not use a claim company automatically if you can challenge the rejection yourself and keep the full payout.

!

Do not escalate before saving the rejection letter, booking proof, flight delay evidence, and your follow-up message.

Rejected claim next step

Prepare A Stronger Second Letter

Check your flight, confirm the compensation amount, and prepare a technical-fault rebuttal without giving away a percentage of the payout.

Frequently Asked Questions

Should I reply if the airline says the technical fault was extraordinary?
Usually yes, unless the airline has already provided strong evidence of a fleet-wide grounding, hidden manufacturing defect, or external safety event. Most rejection emails do not provide that level of detail.
What is the strongest point in a technical fault rebuttal?
Ask the airline to identify the exact fault and explain why it was outside normal airline operations. Routine defects, component failures, maintenance issues, and unexpected faults are not automatically extraordinary.
Do I need a lawyer to challenge the rejection?
For most EU261 and UK261 claims, no. Passengers can reply directly, use ADR where available, or use small claims procedures. The important thing is to be specific, factual, and evidence-led.
Can the airline refuse to share technical records?
They may refuse to share full engineering documents, but they still need to substantiate their defence. You can ask for a written summary, the specific defect, relevant safety notice, and reasonable measures taken.
What if the airline ignores my second letter?
Keep the proof of submission and escalate after your deadline passes. The silence itself can be useful when showing ADR or a court that you gave the airline a fair chance to explain its refusal.

Do Not Let A Technical Fault Rejection End The Claim
