Beach landing for airbus A400M

Are the props on each wing contra-rotating?
Counter rotating, meaning each pair of props turns in opposite directions. However, the engines all turn in the same direction, and two of the props are switched by a gear mechanism. This means that AB doesn't have to produce two different engines.
Part of that about the actual engine portion itself being the same, and a gear, is correct. However there are 2 different complete engine assemblies made. Both use a gearbox but when ordering up a replacement assembly, specify baseline/prop clock or handed/prop counterclock. Handed uses an extra gear, in the gearbox, to achieve counterclock rotation.
Still makes us a a tad angry thou. European protectionism opted for the troubled Europrop TP400 unit over the P&WC PW180 unit, even thou the later was cheaper, weighted less and proven to actually work.

Thanks for the details.
No Mike. Similar idea using a turbine engine to drive the gearbox. But in this case it's single prop driven 1 direction only, either clockwise (baseline) or counterclockwise (handed)
With contra-rotation, that gearbox actually has two portions to it with the rear portion (baseline) driving the front portion (handed)

The contra-rotating propellers do not need to be driven by a turbine engine, it could be a piston engine. One example is the Rolls Royce Griffon engine as used on the Avro Shackleton that used contra-rotating propellers.
Yes they are.
Not the only article by any means but a good place to start is a potted history here http://www.aeroresource.co.uk/operational-reports/pembrey-sands-air-weapons-range/
