Cessna 206 and 207 Stationair
Is the Cessna 206 and 207 Stationair safe? It ranks Shared rankWithin 1 point of other aircraft types: the difference is not meaningful.More in the glossary of 23 small planes we rate, with 42 fatal accidents counted in about 5.4 million US flights since 2008.
Likely range 42 to 53
How the score is built
- Fatal accidents
- 42 in 5.4 million flights
7.8 fatal accidents per million flights. Counted: all civil flights in the United States since 2008 (private, training, charter and other), accidents and unexplained losses; not counted: accidents outside the United States or before 2008, military, test and illegal flights, sabotage, hijackings, shoot-downs and deliberate crew acts.
- Full-loss equivalents
- 34.2
Each counted accident adds the share of people on board who died (1 = no survivors). This is what the score is based on.
- Flights flown
- 5.4 million
Estimated flights of all kinds in the United States since 2008. Flights of all kinds in the United States (private, training, charter and other civil use) 2008 to 3 November 2026, each counted from take-off to final landing: the hours of all US piston singles in each year (active aircraft and hours from the FAA General Aviation and Part 135 Activity Survey), split between types by US-registered aircraft (FAA register, 2,507 of this type in 2024) times how much each type flies against its class (1.64, mostly from airframe hours in NTSB accident records, partly from hours per aircraft seen by ADS-B receivers in 2019-2022), at 0.97 hours per flight from ADS-B tracks: about 142 flights per registered aircraft per year in 2024. Flights and accidents outside the United States, or before 2008, are not used. Against the FAA's hours per helicopter model, this method is off by about 22% on a typical type. Uncertainty roughly ±25%.
- Technology generation
- Single-engine piston plane
Small fleets are pulled toward the record of the other types of their generation: 5.6 full-loss equivalents per million flights over 213 million flights. Weight of this family's own record: 95%.
- Likely range
- 42 to 53
The score is 90% likely to lie in this range, given how few accidents a type has and the error in the estimate of its flights.
- Last fatal accident
- 3 September 2026
GV Air Inc, Dunton, CO, United States of America: 2 of 2 people on board died.
- Aircraft destroyed
- 21
Aircraft the NTSB coded as destroyed in an accident in the United States since 2008, fatal or not, from all causes. The NTSB codes many wrecks as only substantially damaged, so the real number is higher (context only, not in the score).

The NTSB lists 1 more fatal event of the Cessna 206 and 207 Stationair in Puerto Rico, the US Virgin Islands or another US territory, or on a route outside the US states. They are not used, because the flight count covers US flights since 2008 only.
Flight into terrain, often under low cloud in mountains, is the most common fatal Cessna 206 and 207 accident, and one in five of the fatal flights carried paying or ride passengers. Up to 28 October 2026 the US record since 2008 holds 42 counted fatal accidents, which killed 80 people. Twenty-nine were private or other flights. Eight were passenger flights (air taxi, air tour, scenic or rides), two were cargo flights, two were ferry flights and one was training. One more, a test flight in Alaska, is listed but not counted.
Who flies a 206?
Cessna's 206 Stationair is a high-wing, fixed-gear single with a large rear door and six seats. The 207 is the stretched version. Both are workhorses: Alaska and Idaho air taxis, island and lodge supply flights, air tours, skydiving, and floats. About 2,500 are on the US register. Part 135 rules cover the paying flights; private owners fly under Part 91.
Is the per-flight figure fair to a working airplane?
Only roughly. Our small-plane score counts US fatal accidents since 2008 (NTSB database) against US flights (take-off to final landing) estimated from the FAA register and the FAA General Aviation survey. The survey gives hours for all single-engine pistons together; airframe hours in NTSB accident records and, to a lesser degree, hours per aircraft seen by ADS-B receivers set each type's share, but one figure still covers an Alaska air taxi and a privately owned 206. Those measures show that the average 206 makes about 60% as many flights a year as the average 172. A flight in any small plane carries far more risk than an airline flight. See our method and the small planes ranking.
On this yardstick the 206 has nearly three times the fatal accidents per flight of the Cessna 172, though both figures are estimates with wide ranges, and it sits in the middle of the small planes we rate. Confidence is medium.
What kills people in a 206
Flight into terrain is the largest group (17 of 42), then loss of control (12) and engine failure (4). The terrain cases cluster in Alaska and the Idaho backcountry. On 8 April 2016 a floatplane air-taxi pilot turned away from a cloud-covered pass near Admiralty Island, Alaska, circled in poor visibility, stalled and spun; three of four died. On 6 November 2013 a McCall flight turned back from weather and hit terrain near Donnelly, Idaho; all three died. On 28 August 2021 a Part 135 scenic flight flew up a canyon the aircraft could not out-climb near Bernard, Idaho; two passengers died. The NTSB named continuing into the canyon.
Engine loss over water is the other risk. On 13 August 2022 a T207A on an air tour lost power over Lake Powell and ditched; two of the seven on board could not get out and drowned. The NTSB could not find why the engine lost power.
Floats add their own errors. On Beluga Lake, Homer, Alaska, on 10 July 2012, a floatplane landed downwind in strong gusts, a float dug in and it flipped. One of the five on board died.
Skydiving, tours and crowded skies
The data holds one skydiving case: on 19 April 2008 a P206 stalled and spun climbing to jump altitude near Mount Vernon, Missouri, and two of the seven aboard died. On 5 July 2020 a 206 and a floatplane air-tour Beaver collided head-on over Lake Coeur d'Alene; all eight people died. The NTSB found that neither pilot saw and avoided the other aircraft. Lake and tour areas with many aircraft need extra watch.
The newest passenger-flight event is a Smokey Bay Air scheduled flight at Nanwalek, Alaska, on 28 April 2025, which killed the pilot and one passenger. No cause is published.
How to choose an operator
- Ask if the flight is Part 135 (a certificated air-taxi or tour operator) or a private ride.
- Ask what the pilot does when cloud closes a pass, and whether it is a turn-back or a landing decision.
- Ask for the pilot's hours on type and in that region.
- Look up the operator's accident history in the NTSB database.
How to tell if you are on one
Flight trackers show C206, T206 or C207. For a bigger turboprop in the same jobs see the Cessna Caravan; for a tailwheel cousin, the Cessna 180 and 185.
Questions people ask
Is the Cessna 206 safe for an air tour or Alaska air taxi?
The record shows weather as the main hazard: low cloud in mountains and passes, flown under visual rules. Of 8 passenger-flight events since 2008, 7 were air taxi, scheduled or air-tour flights. Before you book, ask how the operator handles weather and whether it flies under Part 135.
How many fatal Cessna 206 accidents are there?
We count 42 in the United States since 2008, up to 28 October 2026, with 80 deaths. Thirteen happened in Alaska.
Is the Cessna 206 a good skydiving plane?
It is a common one, thanks to its big door and load. The record has one skydiving case in our data, on 19 April 2008, when a P206 stalled in a turn while climbing to jump altitude. Jump operators follow separate FAA rules.
What is the difference between the Cessna 206 and 207?
The 207 is a longer version with seven or eight seats. Both are high-wing, fixed-gear planes, and our data groups them.
What ICAO code does the Cessna 206 have?
C206 for the 206 Stationair, T206 for the turbocharged version and C207 for the 207.
