## Probable cause

AN ENCOUNTER WITH WAKE TURBULENCE FROM A BOEING 727.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Vortex turbulence encountered, descent - normal
  - wake turbulence - encountered (cause)
- Loss of control - in flight, descent - normal
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE HOMEBUILT VELOCITY & A BOEING 727 WERE BOTH OPERATING IN THE TCA IN VMC WITH RADIO & RADAR CONTACT ESTABLISHED WITH ATC, AND BOTH WERE BEING ADVISED OF EACH OTHER'S POSITION AND HEADING. BOTH AIRPLANES WERE ON A SOUTHEASTERLY HEADING, WITH THE B-727 OVERTAKING THE HOMEBUILT HIGHER AND SLIGHTLY TO THE LEFT. THE B-727 REPORTED HAVING THE VELOCITY IN SIGHT, AND WAS INSTRUCTED TO MAINTAIN VISUAL SEPARATION AND CLEARED TO DESCEND. AT THE TIME THE B-727 PASSED OVER THE VELOCITY, IT WAS AT 10,000 FT AND THE VELOCITY HAD JUST STARTED A DESCENT FROM 9,500 FT. THE VELOCITY CONTINUED A SOUTHEASTERLY HEADING. APRX 3-1/2 MIN LATER THE VELOCITY PILOT BROADCASTED A MAYDAY THAT HE WAS OUT OF CONTROL. HE THEN SAID HE WAS UPSIDE DOWN. HIS LAST TRANSMISSION WAS '...I HIT THE PROP WASH THE VORTEX...'  WAKE TURBULENCE HAZARDS, PILOT AWARENESS & AVOIDANCE PROCEDURES ARE DISCUSSED IN THE AIRMAN'S INFORMATION MANUAL.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19921024043169A](https://openairdocs.org/incident/19921024043169A), Oct 24, 1992: Amtr VELOCITY, Apopka, FL, Substantial damage, 1 fatal. Lost control and became inverted after hitting a 727S wake. Both were descending in tca under ATC control.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
