Hey Pusher :)
No, the a structural repair manual (SRM) will not superseded or replace D17 when it is required by FAA or other governing bodies.
The SRM and the welding code are two different things entirely.
Your SRM was without doubt made with or by the OEM's who built the aircraft AND the power plant.
The have special knowledge and recommendations of hot section work, dissimilar metals joining and guidance about repairs to precipitation hard enable alloys... Can't fix an engine without it. In my day they were called a class 1 document .
D17.1. Is designed to help aerospace manufacturers and repair depots prove they can carry out what the SRM demands or calls out.
In the aerospace world it's not enough to have the directions. You must prove by both procedure qualification and performance qualification that your plant and your staff are up to the task.
But Lar, That's a terribly expensive proposition !
Qualify every alloy group I might weld on, on a jet engine?
And then qualify every welder to every alloy group he does production or repair welding on?
Yes!
That is just the beginning of the buy-in to get into aircraft welding that has D17.1 requirements
At least you have the SRM in hand... You would be amazed and frightened by the number of folks who wanna fix jet engines without looking at an original manufacturer's manual!
Hope I helped
It's a very big undertaking and I wish you success.
Hoping Lawrence chimes in here...he contributed alot to the writing and implementation of that specification.
