AAIB releases report on Trislander prop de-icer boot separation
11 January 2006

The UK AAIB released the report of their investigation into the July 2004 accident involving a BN-2A Trislander at Guernsey. During take-off a de-icer boot from the left propeller separated, entering the cabin. The de-icer boot separated due to peel stresses generated by forces on the
propeller. The peel stresses arose because of physical or contamination damage to the adhesive bond which occurred because the required filler material was not used at the root of the de-icer boot. (AAIB)
