It certainly did. One of those major deficiencies was the estimated turn around time between flights. It was horrendous and basicly unacceptable. With no real way to change how certain items could be changed out quicker without a redesign of major components, it was doomed to fail from the start. I think the big two were the aileron control ram and the vertical stabilizer. Each required a huge amount of hours to change out.
Initial engineering is never perfect on new projects and there has to be time to iron out the misses. Every new program on which I worked had these issues but they were worked out, given time to address them. The 707 program was full of engineering wrong turns but they were corrected quickly and the program was successful. Basically, though, the program was based on solid engineering integrity foremost and initial expense was tolerated then. The excellence of the product was the driving force and that prevailed throughout the series up to and including the 777. I'll quit at this point.
Cars go through that too. Given time most gets solved. AVRO wasn't given the time. Humans are pretty ingenious. Get enough eyes on a problem and solutions are found. Sometimes it needs to go out in the field where the hands on guys say "Hey, this is dumb".
