After you removed the items, how did you account for them on your weight and balance? The total weight would not have been negligible.

From the maintenance manual...
3-43. SOUNDPROOFING. 3-44. DESCRIPTION. 337-Series aircraft are insulated with spun glass, mat-type insulation. Two types of vibration dampening materials are used. A brush-on type compound on the inner surfaces of the baggage and cabin area and a sheet type that is held in place with an epoxy adhesive. Ipso facto... be very very careful in just yarding it out and then going flying. You're essentially making your aircraft unairworthy. I've seen people talk about how its in there as a vibration thing, now we have a manual reference that confirms it. As an A&P / IA would I recommend taking it all out to check the structure for corrosion? absolutely! Its held on with glue! Thats a recipe to trap water and set up a corrosion cell. By all means, take it out - BUT you need to fit new stuff (or a modern equivalent). DrDave, I tip my hat to you sir. That is not a small job. Have photos of the finished product? Leighton. |

I've heard that some people have removed the little gray patches that are glued on. I've also heard that the best way is with a heated pressure washer. Here's the old sideways picture thing. I have limited abilities at posting pictures I rarely try.
