References:

None

Tools, Equipment, and Materials Provided:

None

Snap-on provided tooling (qty one in each of two pallets unless otherwise indicated): None

Procedures:

The pilot reported a bird strike on landing rollout with power lever at idle. You and your team have already borescoped the High-Pressure Compressor (HPC) verifying no damage to the core of the engine. This will require technicians to remove the fan blades in a uniform manner to prevent shingling of the mid span dampeners and reassembling the engine with a replacement fan blade.

Within the allocated 5 minutes, complete tasks in order:

1. 1. Remove Marked Blade from Fan Hub
   2. Reassemble with replacement blade

Teams are assessed according to the shortest time to accomplish task. A bonus of 10 seconds will be reduced from the base time if reinstallation of the blade is accomplished inside the 5 minute allotted time.
