Gross increase with STOL?

B2C2 · #1 11-22-17, 02:06 PM

I have a Robertson equipped 1969 T337D with the original STC paperwork. the differences in GW increase are for NA vs Turbo models.

NA GW is 4630
Turbo GW is 4700

This is true for all models A-G

for my aircraft all weight above 4500 must be carried as fuel, and max landing weight is 4465.

I can scan and post the full STC if you would like.

A scanned copy of the STC would be much appreciated.

Sorry for the delay. Here's the scanned document. Interestingly, I am apparently missing pages 3 and 4. These presumably cover the A and B models. I don't know why that is. This is what I have in my log books from when I purchased the plane and it starts with the 1967 models. Since mine is a 1969 T337D it is covered by whats in here. I also have the original Installation and Pilots Operating Handbook supplements for the Robertson STC.

Here's a link to the FAA STC registry page which has the full text as a pdf

We have a 70 E mode, before the robertson was added it was a 4400 lb max TO weight plane. After the the robertson was incorporated the max TO weight is now 4630.
