Important Disclaimer

This tool presents statistical analysis of NTSB accident data for experimental amateur-built aircraft. The data is provided for informational and educational purposes only.

This data should not be the sole basis for any aircraft purchase, build, or flight decision. Aviation safety depends on many factors not captured here, including pilot training, recency, weather decision-making, maintenance practices, and individual judgment.

Key limitations of this data:

  • Accident rates are fleet-level statistics — your personal risk depends heavily on how you fly, not just what you fly.
  • Small sample sizes for some aircraft types make their statistics unreliable. A single accident can change a type's fatal percentage significantly.
  • No per-type flight hour data exists for homebuilt aircraft, so true exposure-adjusted rates cannot be calculated.
  • Accident narratives were individually read and classified using an LLM, then fully audited with 614 corrections applied. This is not an official NTSB classification.

The analysis uses an initiator-based approach — identifying the first event in the accident chain rather than the NTSB's probable cause. This is an analytical framework, not an official NTSB classification.

If you are considering building or purchasing an experimental aircraft, consult experienced builders, flight instructors with type-specific experience, and your local EAA chapter. No website can substitute for hands-on guidance.

We believe safety data should be free and accessible to everyone in the experimental aircraft community. This tool is free to use and always will be. If you find it valuable, consider supporting the project.

RV-6 vs RV-7 Safety: What 376 Accidents Tell Us

The RV-6 and RV-7 are the two most popular Van’s Aircraft models ever built. If you are shopping for an RV, this comparison is probably on your mind. Here is what the accident data actually shows.

Why People Compare These Two

The RV-6 was Van’s breakout hit, the aircraft that turned “homebuilt” from a niche hobby into a mainstream movement. The RV-7 replaced it in 2001 with a wider cockpit, updated wing, and easier build process. They share the same basic mission: a two-seat, all-metal, cross-country sport plane that a regular person can build in a garage.

The RV-6 has a much longer accident history simply because it’s been flying since the late 1980s. The RV-7 fleet is younger but now larger. Both have enough data to draw meaningful conclusions.

Head-to-Head: The Numbers

MetricRV-6RV-7
Fleet size (estimated)537584
Total accidents28492
Fatal accidents8233
Fatal percentage28.9%35.9%
First 10 hours accidents12.9%16.7%

Fatal percentage = when an accident happens, how often someone dies. It measures survivability, not how frequently accidents occur.

Wait — the Newer Plane Is More Fatal?

This is the number that surprises people. The RV-7, despite being a newer and arguably improved design, shows a higher fatal percentage (35.9%) than the RV-6 (28.9%). Before you draw conclusions, consider three things:

  • Sample size matters. The RV-6 has 284 accidents — a large, statistically stable dataset. The RV-7 has 92. With fewer data points, a handful of fatal accidents can swing the percentage significantly. As the RV-7 fleet ages and accumulates more (hopefully non-fatal) landing incidents, this number will likely drift downward.
  • The RV-6 has a lot of landing accidents. The RV-6/RV-6A family has 64 landing accidents in the dataset — more than any other cause. Most landing accidents are survivable, which pulls the overall fatal percentage down. More on the nosegear issue below.
  • Pilot mission creep. The RV-7 is slightly faster and more capable than the RV-6. Faster planes attract pilots who push weather, fly longer cross-countries, and are more likely to encounter situations where a bad decision becomes fatal.

What Causes Accidents: Side by Side

Format: total accidents / fatal accidents for that cause.

VFR into IMC: 100% Fatal in the RV-7

Every single VFR-into-IMC accident in an RV-7 in our dataset was fatal. All 5 of them. This is a small number, so the percentage could change with more data, but the pattern is consistent with what we see across the entire E-AB fleet: flying a VFR aircraft into instrument conditions is the single deadliest mistake a pilot can make. The RV-7 is fast enough and comfortable enough that pilots may be tempted to push marginal weather — and the consequences are almost always catastrophic.

The RV-6A Nosegear Factor

If you have spent any time on Van’s AirForce forums, you have heard about the nosegear issue. The RV-6A (the trigear variant) has a well-documented tendency to flip over during landing, particularly on rough or soft surfaces. The nosegear shimmy and porpoising problems led to multiple ADs and service bulletins over the years.

This actually helps explain the RV-6’s lower fatal percentage. Many of those 64 landing accidents were nosegear-related gear-ups or flips — dramatic and expensive, but rarely fatal. They pad the denominator (total accidents) without adding to the numerator (fatal accidents), pulling the fatal percentage down.

The tailwheel RV-6 doesn’t have this issue. And Van’s redesigned the nosegear entirely for the RV-7A, largely solving the problem. So the RV-7A has fewer of those “survivable but counts as an accident” events, which paradoxically makes its fatal percentage look worse.

What Actually Kills RV Pilots

Across both the RV-6 and RV-7, the fatal accident causes fall into a familiar pattern — and they are almost all pilot decisions, not aircraft failures:

  • Stall/spin — The perennial killer. An uncoordinated turn at low altitude, a botched go-around, or a base-to-final spin. Highly preventable with training and awareness.
  • VFR into IMC — A VFR pilot flies into clouds or low visibility and loses control. Nearly always fatal. The RV is fast enough to cover a lot of ground quickly, which can put you deep into bad weather before you realize it.
  • Low-altitude aerobatics / showing off — RVs are aerobatic and fun to fly. Some pilots demonstrate that fun too close to the ground. The data shows this is nearly as fatal as VFR-into-IMC.
  • Engine failures over bad terrain— When the engine quits and there is a field available, RV pilots overwhelmingly survive. When there is not, they don’t. This is a route planning decision more than an aircraft problem.

The Bottom Line

Neither the RV-6 nor the RV-7 is a dangerous airplane. They are among the most popular experimental aircraft ever built, with combined fleets well over 1,000 aircraft, and their accident profiles are broadly similar. The RV-7’s higher fatal percentage is likely a combination of smaller sample size and fewer “harmless” nosegear incidents diluting the number.

If you are choosing between these two aircraft, the safety data should not be the deciding factor. The pilot matters far more than the variant. Stay current, don’t push weather, don’t show off at low altitude, and practice emergency procedures regularly. Those choices will have a bigger impact on your safety than any difference between the RV-6 and RV-7.

Important Caveats

  • Fatal percentage measures survivability when an accident occurs, not how likely you are to have an accident.
  • The RV-7 dataset (92 accidents) is smaller than the RV-6 (284) and will become more reliable as it grows.
  • RV-6 and RV-6A are grouped together. The nosegear issues are specific to the -6A trigear variant.
  • This data should inform your decision, not make it. Talk to experienced RV builders and instructors.
