A salutary lesson from the past for Metro pilots

https://en.wikipedia.org/wiki/Airwork_Flight_23

There are many Metros still flying in Australia. Some are probably crewed with pilots who were only ten years old at the time of this accident in New Zealand. Read and remember this report and don't be tempted to make the same mistake.

Your link didn't work for some reason: https://en.wikipedia.org/wiki/Airwork_Flight_23

That happened only a couple of years after Air Freight lost a Convair 580 after an ice encounter in the same general area, I remember both of those vividly although they were slightly before I started my own flying career.

Sheppey...

Similar sort of event happened here in 2004 in a Merlin, and resulted in a Loss of Control, and a spiral dive from FL160 till control was regained at 5,200 ft. This one happened because the crossflow valve was inadvertently left open and it led to an asymmetric fuel load that was enough to trip the autopilot.

Incident happened at night.

Investigation: 200403209 - Fairchild Industries Inc SA226-T, VH-SSL, 28km W Mount Mcquoid, VOR, 30 August 2004

The wiki article doesn’t explain why they put the extra fuel in one wing...

We operate 10 Metros in Australia and use this accident in our recurrent training program to highlight what not to do. Interestingly the “slip method” is only required to “expedite” the cross flow of fuel and our preferred method is the “gravity” method first. This takes away most of the risk.

When the scenario is set up in the Sim it only takes about 5 seconds to become inverted once the autopilot is tripped (simulating the servo limits been reached).

Unfortunately two people had to die and their families suffer for this lesson to be learnt. My commiserations to those involved.
