It does continue to surprise me how some forum members are subtly misquoted. Bob said that 'It is indisputable that compared to many others and particularly moderns, Sevens are relatively fragile, unreliable and dangerous'. This was challenged, but it seems like simple logic to me.
My modern does 10,000 miles between having the bonnet lifted, and is fitted with more safety devices than could have been imagined 20 years ago a let alone 80. These days you don't even hear about new exhausts being needed let alone clutches or crank shafts.
Wonderful as they are, I don't see how anyone can suggest that an A7 is close to being as robust, reliable or safe as a modern car.
To the subject. On buying my A7 nearly 10 years ago I was advised by a well respected club member to check or change the steering arm. After 70 years of use and abuse who knows what condition it would be in. I decided to change it. Whilst many failures will simply result in grinding to a halt, a steering arm failure at speed is clearly a potentially much more serious scenario.
As for the space race, NASA learnt the hard way about failures and had 5 layers of computer redundancy in the Shuttle. Despite that they still lost 2 due to people thinking they knew better and bypassing the flight safety protocols.
I would rather be safe...
