Pump Housing Containment Cap Failure  by  Paul DeVries    

Analysis mitigated significant aircraft safety and liability concerns when it confirmed pump cap failure was caused by mechanical abuse rather than electrical arcing

Pump Electrical Connector Failure  by  Paul DeVries    

This safety-related investigation identified moisture inside the lead wires as the root cause for electrical connector arcing. Analysis also identified manufacturing errors as the cause of failure in the redesigned connector.

Pitot Tube Heater Failure  by  Paul DeVries    

Analysis helped mitigate a million dollar warranty claim against the company by demonstrating pancake heater failure was caused by an aircraft maintenance issue rather than faulty heaters

Float Switch Failure  by  Paul DeVries    

Analysis helped reduce air carrier maintenance costs by identifying fuel level float switch failures as a design and manufacturing issue

KC-46 Boom Valve Analysis  by  Paul DeVries    

Analysis helped release millions in funding to Boeing by addressing a KC-46 boom manifold valve sticking issue that threatened contract deadlines
