Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary

Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
Inflight upset
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Destroyed

NTSB narrative

About 5 minutes after the experimental amateur-built RV-6 airplane departed from a local airport, an air traffic controller notified the pilot that an Airbus was 30 miles southwest of the airport and inbound. About 7 minutes later, the pilot reported that he had the Airbus in sight and then stated that he was going to take a picture of it. No further communications were received from the pilot. A witness reported observing the RV-6 "rocking back and forth" before the "nose went down" and then seeing two objects come off the airplane when it entered a descent. Another witness reported hearing engine noise before observing the airplane enter a steep nose-down descent. The airplane impacted a house and was destroyed by a postimpact fire.

The two objects that the witness observed coming off the RV-6, which were a headset and PVC material, were later located near the accident site and did not exhibit thermal damage or soot. The exit of the two objects from the airplane's interior indicates that the canopy likely opened in flight, which led to the loss of pitch control. Fire damage precluded examination of the airplane's canopy and systems; therefore, the reason for the canopy opening in flight could not be determined. There was no radar or recorded position and time data for either airplane; therefore, the effects, if any, of wake turbulence from the Airbus on the RV-6 could not be determined.

Probable cause

The pilot’s loss of pitch control due to the in-flight opening of the canopy during cruise flight for reasons that could not be determined because fire damage precluded examination of the airplane’s canopy and systems.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2014-06-21.
