Auckland Seaplanes DHC-2 Beaver ZK-WKA has flipped on landing in the Auckland Harbour. Pilot escaped ok, but the Beaver has sunk. This was the amphibian (-AMA is straight floats).

Re: Boeing 767-300ER Max landing Weight

I believe the 420K weight is the maximum Boeing ever offered on the 763, but your specific frames were not purchased / upgraded to this weight variant. Your company may have them in their docs in case they ended up with a 420K version at some point, or just to cover all possible 763 frames. EDIT: So...

Interesting. Learning something new every day. So with all that said, I'm guessing it's safe to say that 1) no 787 has ever been lengthened or shortened after the airframe had been built and 2) such an exercise would be impractical and more complicated than just simply slotting in an extension.

Re: New Zealand Aviation Thread - January 2019

On the subject of the Q300 - any further thoughts on what will replace them? I note the oldest is 13yr and the newest will be 10yr this year. ATR42? or just upsize to the ATR72 across the fleet? There are only 18 more seats in the ATR72 vs the current Q300 so not that big a jump.
