Apparatus for bending a coiled tubing, the apparatus having a head portion for lateral insertion in a side opening in a wall of a well, the head portion defining a bending path for bending the coiled tubing during feeding thereof through the head portion, and the head portion having a coiled tubing straightener for straightening the coiled tubing during feeding. The coiled tubing straightener is retractable so that it can adopt a retracted position, for lateral insertion of the head portion into the side opening of the well wall. The head portion has, when the straightener is in the retracted position, a profile as viewed in the direction of lateral insertion, and the straightener being extendable for operation to straighten the coiled tubing to an extended position at least partly outside of the profile of the head portion.

The present disclosure is directed to an improved system and method for repairing a bend in a turbine blade of a turbine of a gas turbine engine. The system includes an articulating guide configured to fit into an access port of the turbine. The articulating guide includes a proximal end and a distal end. The system also includes a repair tool configured at the distal end of the articulating guide. Further, the repair tool is configured to fit over the turbine blade. Thus, the repair tool is configured to bend the turbine blade to an unbent position while the turbine blade is secured within the turbine.
