Investigators find multiple causes in Boston Line of Duty Death fire apparatus crash    Lt. Kelley         Tuesday, March 9, 2010  - An independent Board of Inquiry has found at least 15 separate safety and maintenance issues played a role in the 2009 crash of a Boston fire truck into a Mission Hill apartment building. Veteran Fire Lt. Kevin Kelley died when Boston Fire Ladder 26 lost its brakes descending a steep hill and crashed into the building. The Board of Inquiry, made up of 11 Boston Fire Dept. members, notes at least 15 problems played a role in the crash, including the age of the fire apparatus, the installation of improper parts on the and a lack of certified mechanics and maintenance workers for the truck fleet. The findings echo earlier those of earlier investigations into the crash, which have already led to changes implemented by the department in how it maintains its equipment. Kelley was a 31-year veteran of the department.
