i was just wondering, when boeing introduced the new 737 generation, and enancing the dc9's into the 717's.. why is it that they did not change the arming and disarming mechanism, and kept them the same way they are! i think it would have been nicer if they did them into an automatic thing. just curious

Let's see...never breaks down...practically maintenance free...cannot get any simpler to do...cheap to manufacture...why mess with it?

With that kind of reasoning why aren't Boeing still building the Stratocruiser?

I remeber to have heard, that the 737NG is not certified as a new design, but certified by a supplemental type certificate. This has the advantage, that the certification specifications are not the latest available ones for systems that you don't change compared to the old design. As an example, the brake system is still following the specifications of the first certified 737 (so late 60's standard).

By using this practise, Boeing is saving a lot of money, as they do not have to go the full certification process for all the systems on the plane.

Don't flame me for this statement, as it is "second hand knowledge", but it makes well sense to me.

Cheers, Thomas

Ummmm.....Because Radial engines are prone to break.

This plane is built to withstand anything... except a bad pilot.
