According to http://www.staradvertiser.com/news/breaking/20131021_None_hurt_as_plane_makes_emergency_landing_on_Maui_highway.html there were 2 pilots on the first of the 2 Cessna engine failures in the Maui area within 50 days of each other. The 2 pilots were praised but never identified. Ever. The HI Department of Transportation declined to investigate the incident but the FAA and NTSB were investigating.
Photos of that incident are at the very bottom at http://www.thekathrynreport.com/2013_10_22_archive.html
My Google search for Mokulele Express flight 1770 pilots, cause of engine failure yielded no results within the past month so apparently the cause of the engine failure has not yet been reported.

This is a woman with no shred of scientific credential. There is a major controversy right now concerning the use of ethanol in aviation gasolines ... where clearly it would be a major hazard in older engines like the one used in the Caravan.
The ethanol fuel policy is a ridiculous "Green Dream" idea that is economically, scientifically, and even ethically unsound.
