I think this is a mark 1
And this is a civi J31.
19 seats
G reg.
I think there is only 2 AP J31's left now on G reg BTXG and LUVB both of them are pretty good or were the last time I flew them.
The biggest heap of crap jetstream I have ever flown was a N reg one that heap really was a dog, two reds perm on the cap panel so restricted to below FL100 and nothing in the baggage bay and about 4 ambers. Didn't take that job and you wouldn't be allowed to fly it in the UK.
Why ground it? Enter it in the techlog, engineers defer it pull the CB's then fly it around manually which is what you do with the other 95% of J31/J32''s. The gingers do something to it and announce its working again and you use it again. To be honest if wasn't for the fact that pulling the AP out is a major mod and I was told would cost 20k plus for approval all of the AP's would have been pulled out years ago to get 50kg reduction in aircraft weight.
They are actually a very safe robust aircraft, there isn't alot that can go wrong on them that you can't sort out. They are cracking in rough crap wx and are built like a brick !!!!e house. There was one incident in the UK where one was landed with a recorded landing G of over 6g. The plane was a write off but all the punters walked away, in fact one of them said to the local newspaper that it felt like a normal landing.
And you are right the ATPL's have to cover everything from crappy turboprops and !!!!e twins up to the latest Q400's and Boeing/Airbus Models. I have operated Jetstreams from the Faroes to the west across to India in the East. And from the artic circle in the North down to Capetown in the South And I have found quite a bit of the stuff in the ATPL's quite useful.
