   I would cut a couple clean, straight 2x4 or even 2x3 on each side of the broken top element, and make them long enough to catch six inches past the metal web on each end, then sister on each side of the broken element, and secure with liberal amount of the best poly construction adhesive you can get your hands on along the top element, continuing over the metal web where it covers that top element. I would use some C clamps to make sure the surface is held close, especially at the metal, and then use some framing screws to hold the new sister to the existing truss element from each side.

   I would install 3 or 4 vertical supports under the break, jack it baCK in position, then glue and screw a piece of 1/2" ply on both sides of the truss.

   A combination of the 2 solutions above might be best..

   @ Unncle Mike - I would not rely on construction adhesive alone for a permanent fix. and 6" and a couple of framing screws may not be enough to carry the chord force (a 2x4 chord may have over 5,000# load on it depending on the location) If scabbed members are used they should extend beyond the damaged portion and attach to the chord beyond with enough nails/screws to carry the chord force.

   @ florida - I like the plywood gusset plates each side for truss fixes but usually I see a new chord member added under the original damaged one and then plywood on each side to transfer load.

   Either way it is hard to know how to fix this without having an idea of the load in the member (depends on span, web layout and location of damage) I would recommend either hiring a truss supplier to run a field repair for the truss or hiring a local engineer to specify a repair.

   The damage also makes me wonder why this specific chord was damaged and whether the other trusses in the area are suspect as well or if there is additional damage on this truss. I don't see a visible knot or detect or evidence of plumber/electrician cutting away at the truss.. Floor truss damage from overload is rare enough that it might be a good idea to have someone come take a look at the floor system in general.
