# NTSB investigations, 2012: Aircraft structural failure

NTSB aviation accident and incident investigations since 1962: the probable cause, findings, aircraft, crew, weather and docket of each, linked to the FAA registry and the FAA’s own reports.

## Latest cases

- [NTSB CEN13LA071](https://openairdocs.org/ntsb/CEN13LA071.md): Scott Ironsides · East Troy, WI · Accident · Minor injuries · Limited investigation · Final report · Nov 24, 2012 · N1879 · Substantial damage
  > Failure of the steel weld fittings on the right main landing gear.
- [NTSB WPR13LA050](https://openairdocs.org/ntsb/WPR13LA050.md): Sater Coot A-Amphib · San Andreas, CA · Accident · 1 fatal · Limited investigation · Final report · Nov 23, 2012 · N8VS · Substantial damage
  > The pilot's excessive flight control inputs, which led to flight that exceeded the structural limits of the airplane and resulted in structural failure of both wings.
- [NTSB ERA12LA537](https://openairdocs.org/ntsb/ERA12LA537.md): Quad City Ultralights Challenger II · Ocala, FL · Accident · 2 fatal · Limited investigation · Final report · Aug 30, 2012 · N2481P · Substantial damage
  > The pilot's inadvertent overstress of the airplane, which resulted in the in-flight separation of the outer section of the right wing.
- [NTSB CEN12CA600](https://openairdocs.org/ntsb/CEN12CA600.md): Evektor-Aerotechnik Sportstar · Columbus, OH · Accident · No injuries · Data collection · Final report · Aug 26, 2012 · N904LA · Substantial damage
  > The failure of the right main landing gear strut due to a preexisting crack.
- [NTSB DCA12IA113](https://openairdocs.org/ntsb/DCA12IA113.md): Boeing 737-3H4 · El Paso, TX · Incident · No injuries · Incident investigation · Final report · Jul 27, 2012 · N379SW · Minor damage
  > the rupture of the nose landing gear hydraulic line that resulted from abrasions due to contact with the nose landing gear tire. Contributing to the incident was the incorrect installation of union and restrictor on the actuator.
- [NTSB CEN12IA377](https://openairdocs.org/ntsb/CEN12IA377.md): Piper PA-28R-200 · Lacon, IL · Incident · No injuries · Incident investigation · Final report · Jun 18, 2012 · N4350T · Minor damage
  > The propeller blade’s failure due to a fatigue crack that originated from a surface gouge that resulted from foreign object damage to the propeller blade that occurred at an unknown time.
- [NTSB WPR12FA164](https://openairdocs.org/ntsb/WPR12FA164.md): Cessna 320D · Green River, WY · Accident · 1 fatal · Field investigation · Final report · Apr 12, 2012 · N32EG · Destroyed
  > The pilot's failure to maintain airplane control while maneuvering in marginal weather conditions, which resulted in an exceedence of the design stress limits of the airplane and a subsequent in-flight structural failure.
- [NTSB CEN12FA196](https://openairdocs.org/ntsb/CEN12FA196.md): Beech 35 · Glencoe, MN · Accident · 3 fatal · Field investigation · Final report · Mar 21, 2012 · N3871N · Substantial damage
  > The non-instrument-rated pilot’s continued flight into instrument meteorological conditions, which resulted in the design limits of the airplane being exceeded and an in-flight breakup.
- [NTSB CEN12LA218](https://openairdocs.org/ntsb/CEN12LA218.md): Cessna 182A · New Philadelphia, OH · Accident · No injuries · Limited investigation · Final report · Feb 18, 2012 · N20DE · Substantial damage
  > The inadequate maintenance of the wheel attachment bolts, which resulted in the left wheel separating from the landing gear during landing due to ductile overstress fractures.
