## Latest cases

- [NTSB WPR24LA161](https://openairdocs.org/ntsb/WPR24LA161.md): Aerospatiale SA315B · Hildale, UT · Accident · Minor injuries · Class 3 · Limited · Final report · May 27, 2024 · N57948 · Substantial damage
  > Maintenance personnel’s failure to properly secure the EGT thermocouples, which resulted in catastrophic overtemperature of the engine and a total loss of engine power.
- [NTSB ENG17IA028](https://openairdocs.org/ntsb/ENG17IA028.md): Bombardier CL 600 2C10 · Chicago, IL · Incident · No injuries · Incident investigation · Final report · Jun 10, 2017 · N715SK · Minor damage
  > A Bombardier CRJ700 No. 1 engine failure caused by buckling of the combustion outer liner due to fatigue cracks. The liner buckling resulted in airflow disruption and reduced engine performance. The engine fuel control unit attempted to compensate for the…
- [NTSB ENG14IA029](https://openairdocs.org/ntsb/ENG14IA029.md): Bombardier CRJ700 · Hodeida, Yemen · Incident · No injuries · Incident investigation · Final report · Sep 13, 2014 · 7O-FAB · Minor damage
  > The probable cause of the undercowl engine fire was the burn-through of the combustion chamber inner liner from the accumulation of dust that became molten during operating and infiltrated the combustion chamber thermal barrier coating causing it to spall off…
- [NTSB CEN14IA270](https://openairdocs.org/ntsb/CEN14IA270.md): Bell 407 · Eugene Island 182A · Incident · No injuries · Incident investigation · Final report · May 30, 2014 · N1197 · No damage
  > The improper repair of the outer combustion case, which led to its ultimate failure due to the continued progression of a fatigue crack and resulted in a partial loss of engine power during takeoff.
- [NTSB WPR13IA144](https://openairdocs.org/ntsb/WPR13IA144.md): Bombardier DHC-8-402 · Danville, CA · Incident · No injuries · Incident investigation · Final report · Mar 5, 2013 · N417QX · Minor damage
  > The failure and separation of a section of the No. 2 engine's combustion chamber's small exit duct (SED), which created an airflow disruption that led to an engine surge and subsequent fire. Contributing to the accident was the insufficient weld penetration…
- [NTSB CEN13LA119](https://openairdocs.org/ntsb/CEN13LA119.md): Bell 407 · Big Lake, TX · Accident · No injuries · Limited investigation · Final report · Dec 29, 2012 · N534MT · Substantial damage
  > The loss of engine power due to the fatigue failure of the outer combustion case at the fuel nozzle port. Contributing to the accident was the operator’s failure to conduct the recommended routine inspections of the outer combustion case.
- [NTSB ENG12IA001](https://openairdocs.org/ntsb/ENG12IA001.md): Boeing 757-251 · Atlanta, GA · Incident · No injuries · Incident investigation · Final report · Oct 10, 2011 · N553NW · Minor damage
  > the return to service of overhauled airplane engine parts with undetected fatigue cracks, resulting in complete loss of engine power and uncontained engine failure. A contributing factor was the inadequate diffuser and HPT case inspection procedure.
- [NTSB WPR10FA387](https://openairdocs.org/ntsb/WPR10FA387.md): PZL Mielec M18 · Meridian, CA · Accident · Minor injuries · Field investigation · Final report · Aug 6, 2010 · N70461 · Substantial damage
  > Long-term deterioration of multiple engine fuel vaporizers that led to material failure of multiple turbine blades, which resulted in a complete loss of engine power. Contributing to the accident were the exceedance of specified engine inspection intervals…
- [NTSB ERA10TA261](https://openairdocs.org/ntsb/ERA10TA261.md): Bell 407 · Abingdon, VA · Accident · No injuries · Final report · May 11, 2010 · N31VA · Substantial damage
  > The improper repair of an engine component by a repair facility, which resulted in a complete loss of engine power. Contributing to the accident was the failure of the repair facility to recognize that an improper repair had been accomplished, which allowed…
