engine mount gusset installation

[Monticello Flying Club]

Has anyone installed the engine mount gussets required by SB M20-192A to eliminate the recurrence of the AD? Does someone sell these gussets and about how much did it the whole work cost you? We are overhauling our engine and now would be the time to do it.

Have you tried Aerospace Welding in Minneapolis?

I had LASER put them on the mount on my F about twenty years ago. Any decent welder could do it.

Very true, but any repair or alteration to the engine mount is a major repair or alteration thus must accompany the proper paperwork from either a repair station like Lasar or have an IA file a 337 using the SB as the approved data for the alteration. Possibly since the alteration is done by the manufacturers drawing its no longer a major alteration.   But I would do a little investigating and maybe the SB even addresses this (I haven't read it). My only point is that the approval may need more than just a log book entry as a minor alteration.

It is a straight forward 337. Cant imagine anyone having an issue with it.

Log book entry.

Definitely get the cost to have the engine mount inspected, cleaned and painted while it is separated from the engine...

It is a small cost added to the R&R of the bigger job.

Thanks everyone.  Both Aerospace Welding in MN and Aero Engine Mount in NY quoted $650 to clean, inspect, install gussets and repaint.  Since our overhaul is being done in NY we went with Aero Engine Mount since the shipping will be less.  I will let you know how it turned out.
