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
En route
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
Structural icing
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Substantial

NTSB narrative

The noninstrument-rated private pilot obtained a computerized weather briefing about 9 hours before he departed on a night cross-country flight. At that time, neither ice nor low visibility conditions were forecast along his intended flight route. The pilot did not obtain any additional weather information before takeoff or while en route. Weather conditions at the time of departure were marginal visual meteorological conditions, and instrument meteorological conditions (IMC) were forecast along the route of flight. The weather conditions were also conducive to the accumulation of structural icing. The pilot reported that, about 2 hours into the flight, the airplane entered IMC. He stated that he looked out at the wing and saw that "frost" had started to build up. The airplane was unable to maintain altitude, so the pilot added power and focused on maintaining level flight at a safe airspeed as the airplane continued to descend until it impacted trees and the ground. The airplane came to rest on its left side in an ice-covered field and sustained substantial damage to both wings, all three landing gear, and the right horizontal stabilizer.

Probable cause

The noninstrument-rated pilot’s failure to obtain weather briefings immediately before and during the flight and his continued flight into icing conditions, which resulted in the airplane’s loss of performance and the subsequent controlled descent into trees and terrain.

  • 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. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2013-12-01.
