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.
| Request | Why it matters |
|---|---|
| Exact technical defect | A 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 discovered | A defect found during normal turnaround, inspection, or pre-flight checks often points to ordinary operational risk. |
| Maintenance or engineering record summary | You are not asking for confidential manuals. You are asking the airline to prove the basis of its refusal. |
| Manufacturer or regulator notice | If the airline claims a hidden manufacturing defect or fleet-wide safety issue, ask for the notice that supports that claim. |
| Reasonable measures taken | Even 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. |
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.
