## Newest cases

- [NTSB WPR25LA175](https://openairdocs.org/ntsb/WPR25LA175), Jun 13, 2025: Cessna 182P (N78720), Hyampom, CA, substantial damage. Probable cause: The pilot’s failure to use carburetor heat, which resulted in a loss of engine power due to carburetor icing and a subsequent impact with terrain during a forced landing.
- [NTSB ERA25LA122](https://openairdocs.org/ntsb/ERA25LA122), Feb 10, 2025: Allyn Kaste Rans S-19 (KIT) (N258DK), Doylestown, PA, substantial damage. Probable cause: The pilot’s inadequate maintenance and preflight inspection.
- [NTSB CEN25LA054](https://openairdocs.org/ntsb/CEN25LA054), Dec 1, 2024: American AA-1B (N6242L), Brenham, TX, substantial damage. Probable cause: A partial loss of engine power due to an obstructed induction system from a mud dauber nest.
- [NTSB ERA24LA333](https://openairdocs.org/ntsb/ERA24LA333), Jul 31, 2024: Cirrus Design SR20 (N124RR), Egg Harbor City, NJ, substantial damage. Probable cause: A partial loss of engine power due to the fatigue failure of the alternate air valve, which separated and partially obstructed the engine’s induction system.
- [NTSB CEN24LA200](https://openairdocs.org/ntsb/CEN24LA200), May 27, 2024: Piper PA28 (N56466), Taylor, TX, substantial damage. Probable cause: A partial loss of engine power due to an incorrect carburetor air inlet hose, which led to a reduction in air flow to the engine.
- [NTSB WPR24LA154](https://openairdocs.org/ntsb/WPR24LA154), May 16, 2024: Cessna 172G (N4448L), Lakeport, CA, substantial damage. Probable cause: The pilot’s inadequate use of carburetor heat, which resulted in a total loss of engine power shortly after takeoff due to fuel starvation as a result of carburetor ice.
- [NTSB ERA24FA160](https://openairdocs.org/ntsb/ERA24FA160), Apr 2, 2024: Arthur B Canning Merlin Lite (N622PC), Mulberry, FL, substantial damage, 1 fatal. Probable cause: The pilot/builder’s modifications of the motorglider’s engine, which resulted in an excessively lean fuel air mixture, preignition, piston failure, and a subsequent total loss of engine power during…
- [NTSB ERA24FA078](https://openairdocs.org/ntsb/ERA24FA078), Dec 31, 2023: Piper PA46R-350T (N539MA), Mooresville, NC, substantial damage, 1 fatal. Probable cause: A missing induction clamp, which allowed the induction hose to the left side intercooler to become disconnected, resulting in a total loss of engine power due to an overly rich fuel/air mixture.
- [NTSB CEN22LA421](https://openairdocs.org/ntsb/CEN22LA421), Sep 14, 2022: Piper PA-28R-180 (N3713T), Broomfield, CO, substantial damage. Probable cause: A partial loss of engine power due to a collapsed induction hose that blocked engine intake airflow.
- [NTSB ERA22LA307](https://openairdocs.org/ntsb/ERA22LA307), Jul 10, 2022: Mooney M20F (N600FS), Cragsmoor, NY, substantial damage. Probable cause: The pilot’s decision to continue toward rising terrain despite observing the airplane’s decreased climb performance after takeoff, which resulted in flight into terrain.

NTSB has coded findings and defining events since 2008; earlier cases used its older occurrence and cause codes and aren't counted.

Findings: https://openairdocs.org/ntsb-findings.md. Defining events: https://openairdocs.org/ntsb-events.md. Phases of flight: https://openairdocs.org/ntsb-phases.md. Every investigation, filtered by finding, event, phase, state, year or model: https://openairdocs.org/ntsb.md (for example ?state=MI&fatal=1).

NTSB's definitions: Accident and incident, 49 CFR 830.2 (https://www.ecfr.gov/current/title-49/subtitle-B/chapter-VIII/part-830/subpart-A/section-830.2), CICTT occurrence categories (PDF) (https://www.ntsb.gov/safety/data/Documents/datafiles/OccurrenceCategoryDefinitions.pdf), CICTT phases of flight (PDF) (https://www.ntsb.gov/safety/data/Documents/datafiles/PhaseofFlightDefinitions.pdf), and NTSB coding manual, before 2008 (PDF) (https://www.ntsb.gov/GILS/Documents/codman.pdf). NTSB publishes no definitions for its findings, only their names.
