Every year, thousands of technical reports quietly pile up inside the Federal Aviation Administration’s filing system, each one flagging something that went wrong somewhere in the country’s fleet of commercial aircraft. Most travelers never hear about them. A new analysis just pulled back the curtain on what is actually inside those files, and the numbers are enough to make even a seasoned flyer sit up.
Travel company Global Work & Travel combed through 36,974 Service Difficulty Reports filed with the FAA between January 1 and August 21, 2026. What they found was a snapshot of an industry constantly catching and fixing problems, some routine, some considerably more alarming on paper.
The Numbers That Stand Out
Doors dominated the findings, appearing in a staggering 7,637 reports. Smoke showed up 751 times. Landing gear issues were flagged 526 times, and fire or flame references appeared in 387 reports. Pressurization problems accounted for 325 filings, hydraulic system issues for 319, and 75 reports referenced an engine shutdown.
| Issue | Reports |
|---|---|
| Doors | 7,637 |
| Smoke | 751 |
| Landing gear | 526 |
| Fire or flames | 387 |
| Pressurisation or cabin pressure | 325 |
| Hydraulics | 319 |
| Emergency declared or landing | 289 |
| Burning smell or odour | 287 |
| Oxygen masks or equipment | 109 |
| Engine shutdown | 75 |
Underneath those headline categories, the deeper mechanical data tells its own story. Corrosion turned up in 7,429 reports and cracking in 6,468, with thousands more parts logged as inoperative, damaged, or faulted. Structural wear, it turns out, is a far bigger presence in these files than the more dramatic-sounding entries like fire or engine shutdown.
Before Anyone Panics, Here’s the Context That Matters
It would be easy to read these figures and assume the skies are less safe than they seem. That is not what the data shows, and it is worth being precise about what a Service Difficulty Report actually is. These reports document malfunctions, defects, and maintenance findings, and the vast majority relate to issues caught and resolved on the ground, not emergencies experienced mid-flight. A single report can also reference more than one issue at once, so the categories overlap rather than stack into separate incidents.
Reports mentioning smoke made up roughly two percent of the total. Engine shutdown references accounted for about two tenths of one percent. Framed against the scale of the dataset, the categories capable of triggering real anxiety are a small slice of a much larger, largely routine paperwork trail.
Which Airlines Filed the Most Reports
Among major US carriers, American Airlines logged the highest number of reports overall at 6,761, followed by Southwest at 5,934, Delta at 4,488 and United at 3,568.
Smoke references were highest for United, with 247 reports, compared with 91 for Delta and 74 for American. Landing gear issues were most frequent for American, at 108 reports, while engine shutdown references were highest for Delta, with 14.
It is worth being clear that these totals are not a safety ranking. Airlines fly different numbers of aircraft on different numbers of routes, operate different fleet ages, and follow different reporting habits, all of which shift the raw counts without saying anything definitive about which carrier is safer to fly.
What Travelers Should Actually Do With This Information
Jürgen Himmelmann, co-founder and chief executive of Global Work & Travel, said the figures are less alarming in context than they might first appear, since aircraft undergo extensive checks and the documentation of issues is itself part of how the system stays safe.
His more practical advice centers on what happens when a technical issue does cause disruption. Travelers should keep every piece of communication from their airline, along with receipts for any food, accommodation, or alternative transport paid for as a result of a delay. Building extra time around important connections is worth doing wherever possible, particularly for anyone traveling on separately booked flights, since a delay on the first leg can leave the traveler responsible for rearranging the rest of the trip. For longer journeys, having travel insurance in place from the point of booking is one of the simplest ways to avoid a single disrupted flight cascading into a ruined itinerary.
None of this means the modern aircraft fleet is falling apart mid-air. It means the paperwork behind aviation safety is doing exactly what it is supposed to do, catching problems early and often, long before they ever reach a passenger.
