FlightFollowerMicroburst Windshear Slams Caravan During Go-Around at SLC
The Go-Around Was the Right Decision — But the Weather Was Still There
Cessna 208B N877FE arrived at Salt Lake City International Airport on July 13, 2022, with thunderstorms and windshear already affecting the airport. The pilot had received multiple weather warnings, including a report of a 20-knot windshear gain on final.
The official record
This occurrence was investigated by the National Transportation Safety Board under accident number WPR22LA251. The Board records the event as occurring on 14 July 2022 at Salt Lake City, UT. The aircraft is identified as a CESSNA 208B, registration N877FE. The highest injury level recorded is minor.
The Board’s record additionally lists phase of flight recorded as landing, weather conditions recorded as Visual (VMC); Visual (VMC), operating under 135.
The investigation is closed. The Board determined the probable cause to be:
The pilot’s inability to maintain control of the airplane when it encountered a microburst during a landing attempt and a go-around near known thunderstorm activity. Contributing to the accident was an inadequate amount of wind sensors and wind shear detection equipment used by the ATC tower to detect microburst activity at the airport.
NTSB, accident WPR22LA251
A probable cause is the Board’s determination of what brought the occurrence about. It is reached after the investigation closes and supersedes any earlier account, including contemporary reporting and anything inferred from the recording alone.

This reconstruction was researched from official investigation records where they exist, the original air traffic control recording, and contemporary reporting. The aircraft movement, timeline and written account were assembled independently by Flight Follower. Where an investigation is open or no probable cause has been published, the account says so rather than offering one.

The aircraft was cleared for a visual approach behind a Boeing 757. During the landing flare, the Caravan began drifting sideways. The pilot could not maintain directional control and initiated a go-around.
The go-around removed the airplane from an uncontrolled landing, but it did not remove the microburst. At about 30 feet above ground level, the pilot lowered the left wing to counter the drift. A downdraft then forced the aircraft back toward the ground.
The NTSB reconstruction shows that the airport was already producing multiple warning signs. ATC had a windshear PIREP, the preceding Boeing 757 reported windshear, and controllers issued additional windshear alerts.
At the same time, the tower's own wind sensor did not fully represent the conditions affecting the accident area. Around the accident time, the tower sensor reported a much weaker gust than the airport's ASOS. The tower's windshear detection systems also did not generate a microburst alert until after the accident.
The result was a classic low-level weather problem: different sensors were seeing different parts of a rapidly changing wind field.
The Go-Around Became a New Exposure
The pilot's decision to go around was a reasonable response to losing directional control during the flare. But the airplane remained only a few feet above the surface while the convective outflow continued.
The NTSB later used this accident as the basis for broader recommendations about wind-sensor placement and windshear detection at Salt Lake City.
What the Records Show
The NTSB determined: “The pilot’s inability to maintain control of the airplane when it encountered a microburst during a landing attempt and a go-around near known thunderstorm activity.”
The Board also identified inadequate wind-sensor and windshear-detection coverage used by the tower as a contributing factor.
A Broader System Safety Case
This accident is more useful than a simple pilot-error narrative because the investigation identified weaknesses on both sides of the runway environment.
The pilot had multiple warnings, but the actual wind field changed rapidly. The tower had sensors and alerts, but their placement did not provide a complete picture of the conditions affecting the runway. The preceding Boeing 757's report was therefore particularly valuable because it provided direct aircraft experience in the same environment.
The NTSB subsequently recommended improvements to wind detection at Salt Lake City. That turns the accident from a single aircraft event into a system-safety lesson about how airports detect and communicate rapidly changing convective hazards.
- A go-around in convective weather does not remove windshear exposure.
- Reports from preceding aircraft can be critical when surface sensors disagree.
- Airport wind sensors must cover the areas that matter to arriving and departing aircraft.
- Microbursts can overwhelm an aircraft at extremely low altitude.
- A go-around should be initiated before directional control is lost, but the weather environment must still be respected.
