Crash
I have already recieved a service bulletin from the FAA concerning this crash. It states the failure at station 150 in wing. They stated every one should check if you had the modification of wing extention with fuel tanks and winglets installed. They want you to check ribs, check for wrinkled skin beyond station 150 and check for smoking rivots. The crashed 337 was a G model. I was wondering if on the models G and H that have 148-150 gallon tanks you have more weight on end of wing. Do the earlier models before G have more ribs in wing at that point were the factory installed the standard 150 gallon tanks. The more weight you hang on the end of wing the more stress it adds beyond the strut support. The aircraft that crashed also had the 550 engines with turbos capable of more power and with 2 of these engines weighing over 700 pounds more that my IO-360. Add wing extension with tanks that might be full, winglets and 5 people. He was at or over gross weight. You do the math.
