Nico,
That is correct go to the link below and look at page 12 of the PDF file

Interestingly it does not increase lift so should not affect fatigue life of the
wing.

I have only lost an engine once and that was in the 685. Trimmed the plane and
used my normal landing procedurs except hoding the gear up until the landing was
assured. It was a non event except as John mentioned above it became a ground
steering problem once I slowed to a taxi.

Outstanding advice from Bill Leff.
Since Mr. Leff brought up the icy runway idea ... the ONLY time I'd
use less than full flaps when landing a Twin Commander was if I was
carrying airframe ice on the approach. Full flaps could aggravate a
tail plane stall.
I wonder if anyone else caught the very sublte but very important
hint: Bill Leff is offering Commander Training. If I was looking for
Commander training, I'd go to him (and I used to make my living doing
Commander training!).
I've landed in snarling, ripping, Santa Anas tumbleweed blowing,
sand-blasting, 90 degree cross winds in a Commander. Full flaps.
Differential power does the trick, coupled with that nice high wing
that allows all the side slip bank angle you could ever want.

I recommend full flaps on all landings except maybe very icy runways.
Use
differential power when exceeding more than 1/2 rudder travel. When on
the
ground the aircraft has a negative angle of attack and sticks quite
well.
Raising the flaps after touchdown helps some but they retract so slow
you will
be
stopped before they are completely up.

There is nothing safer than intimate knowledge of your plane from an operational
and design standpoint. It was Keiths intimate knowledge of the 685 that enabled
me to finally become a competent pilot and a complement from Keith is indeed
high praise.

I will second WCG's suggestion on Bill. And I speak from experience.
I bought my Commander without having my ME rating. Dick Wartinger did the
pre-buy for me and then hooked me up with Bill. At the time Bill was an
MD-80 instructor at TWA (now American). Due to insurance requirements I had
to spend 25 hours with him and I can tell you he did everything in the world
to me - including pulling engines on take off roll - before and just after
take off (and on hot days). Bill is definitely old school as well as new
school. I think I was his first piston student in 20 years - so he insisted
on the best of the good-old-days as well as the new stuff of today.
One of the best things he had me do was may make an actual single engine
landing - not simulated - but feathered left engine out - and because of his
training it was a snap - and it was as if he had ESP. To make a long story
short - on my ME check ride (with a for-real FAA employee as the examiner) I
actually had to make a single engine landing. It was a very hot summer day
in August and we were 10 miles from the airport with the right engine out
(long story there). Due to Bill's training I was not a bit nervous and the
landing at Lunken was a breeze - even taxied all the way back to the FBO and
parked her in an out of the way spot! (I got a discontinuance because the
FAA man wanted two to see two more take offs and landings - which he got out
of me two weeks later.)
Thanks to Dick Wartinger I now a have a great instructor and a friend.

Great history, Bob.
What's the golden rudder award, Bob?
Pardon my ignorance.
