Inspection

Regardless of the material-of-construction used in your Tail Rotor Blade (057) inspect it for obvious damage - especially after a Tail Blade strike or sudden-stoppage like getting tangled in grass. Look for scarred blade tips, dents and bends. The entire blade surface should be smooth and clean. If it is dirty, throw it in with the dishes and clean it up. I wouldn't try the dishwasher though - it may warp in the high heat.

Check the drive lugs that engage the Tail Rotor Drive Gear (059) for damage and proper fit within the Drive Gear (059). Figure 1. The lugs should fit snugly.

Removal

Nothing could be easier than the removal of the Tail Rotor Blade (057). Remove the Silicone Tube Section (024) that secures the Tail Rotor Blade (057) to the Tail Rotor Shaft (065). Disengage the Tail Rotor Blade drive lugs from the Tail Rotor Drive Gear (059). Slide the Tail Rotor Blade (057) off of the Tail Rotor Shaft (065). Figure 2.

Repair

Not much to repair here. You can sand/file out any nicks that most likely appear at the blade tips.

Installation

Prior to installing the Tail Rotor Blade (057) onto the Tail Rotor Shaft (065) engage the drive lugs on the Tail Rotor Blade into the holes on the Tail Rotor Drive Gear (059). Figure 3. Hold the Tail Rotor Shaft (065) in place while you install the Tail Rotor Blade and Gear as an assembly. Make sure the drive lugs are completely engaged with the Drive Gear (059). There should be no gap between the Tail Rotor Blade hub and the Drive Gear (059).

Slide a Silicone Tube Section (024) onto the Tail Rotor Shaft (065) securing it in place. While holding the Tail Rotor Shaft tight against the Tail Rotor Gearbox Housing (061) with one hand, push the Silicone Tube Section (024) tightly against the Tail Rotor Blade (057) with the other hand. Figure 4. This is done to lightly load the Bearings (062) so that the inner race spins on the outer race rather than the Tail Rotor Shaft (065) spinning inside the Bearing (062) inner race.
