California Man Sentenced to Falsely Certifying Oxygen Cylinders for Aircraft

On October 29, 2015, Danniel Allen Hoose, of Redding, California, was sentenced in U.S. District Court, Sacramento, California, related to falsely certifying oxygen cylinders for aircraft.  He was sentenced to 36 months' probation and ordered to pay a fine of $3,000.  He pleaded guilty in July 2015 to one count of falsely certifying more than 570 oxygen cylinders for re-use, including re-use in aircraft.

In the spring of 2013, Hoose represented that he performed hydrostatic testing on a special permit oxygen cylinder installed in an aircraft. But, no such testing was done.  The investigation determined that Hoose's re-qualification equipment was in disrepair so he was unable to properly test the cylinders in accordance with Pipeline and Hazardous Materials Safety Administration (PHMSA) regulations.  Hoose falsified the cylinder hydrostatic testing certifications and returned the cylinders to their owners for use.

We conducted this investigation with assistance from PHMSA.
