Re: Negligent certification

Well said and very clearly put. Have one of these on me!

IMHO there should be mandatory re-certification if the centre of gravity and or mass of the aircraft changes due to new engines and/or engine mounting pylons. The whole flying model will change quite dramatically when this happens.

Airbus saw this when they stretched the A320 into the A321. The A321 seems to fly much more like a lead baloon especially when compared to the A318. Same basic aircraft but...
