Glaringly missing from that site is any mention of a STC.



People with light aircraft often notice a black plastic tape applied
to the prop's leading edges as minor erosion protection.
As far as I can recall, it's not an STC item.

Read the second paragraph.

STC yes; 337 no.



Ouch! If they want $74 for a tape, you bet it's STCed
even as a minor mod
