Field Repair For Nicks in MT Props
Posted: Sun May 15, 2022 4:19 am
Flew my DA40 from Atlanta to Vegas and found a couple of strange nicks on the trailing edge of my MT prop when I landed at KVGT (Amazing that there is loose gravel all around the main terminal ramp). Luckily my leading edges are clean. Reading through MT Service Letter 32, they suggest using 5-minute epoxy to cover any exposed areas of the wood core, which you can see in the pictures below. That letter mentions nick and gouge sizes < 15mm or < 0.5 sq in are not airworthiness issues. But they suggest covering anything that exposes the wood core:
2.5. Damaged Trailing Edges (continued)
Field Repairs
Sealing of damage with 5 Minute Epoxy (e.g. Devcon ™ or equivalent)
(Damage not deeper than 5 mm (0.20 in) and not wider than 15 mm (0.60 in).
Minor damages on the trailing edge may be sealed with 5 minute epoxy.
While it seems somewhat straightforward to cover a spot along the trailing edge, I would really appreciate any advice on how to handle this on the corner of the blade tip. The most readily available epoxy seems to be by Loctite or Gorilla. Has anyone used these?
Lastly, this seems like minor owner repair. Or does this need to be done by a prop shop? Thoughts?
