So I gather from all this that we can't find anything that says you "can't
take off" in the FARs?

I remember reading about a publicity stunt some manufacturer did back
in the 70s where they flew their aircraft a few hundred miles with one
of the props completely unattached to the aircraft/engine. I think it
was the Aero Commander 500, IIRC.


Actually, it was the prototype Aero Commander, back in the early 1950s.
They flew from Oklahoma to Washington, DC, with one of the props
strapped to the cabin floor.

I understand some learjet dealers used to take off on one engine with
a load at high airports to make a point..

But it had enough power that you could exceed the airframe redline in
level flight if you pushed the throttles up....

You'll find the limitations in the pilot operating handbook: the fars
demand you observe those handbook limitations.


That would be 91.213 *Inoperative instruments & equipment.

Of course, if there happens to be an approved minimum equipment list that
says that single engine takeoff is OK...

So you could disable it and placard it inop?

I doubt that very seriously. You probably meant to say "with one
engine inop". BTW, it's called "ferried", past tense of "ferry".

I imagine that under the right circumstances a twin might legally
depart on one engine.


If the FAA would issue a "Ferry Permit", also doubtful.

I'm wondering if it's legal? I'm referring to a recent crash where the
pilot decided to take off on one engine and clipped a tree.

Looking over 91.205, you can't take off with out a magnetic compass.. but
it doesn't say anything about one engine out of two.

OK, so this thread is beginning to bother me; and, news reports being what
they are, it is not possible to parse the meaning from the original post.
In the particular case of the accident aircraft: was the take off attempted,
in its entirety, with an inoperative engine or did an engine failure occur
at some later point in the takeoff seqfuence?

The reason for asking is that, in the event that the failure occured at some
point during the normal take off sequence; then the questions would center
on the preflight calculations regaerding density altitude, gradient,
distance to obstacles, and adherence to recommended pilot techniques. OTOH;
if the take off was attempted, in its entirety, with an inoperative engine
(which seems improbable); then the questions center on the proper planning
and execution of a test flight--especially the planning to avoid any
collateral damage and the assurance that only necessary crew would be on
board.

So, since the information provide did not readily facilitate a search for
the report of the particular incident, please be a little more specific.

Thanks,
Peter

No, that was Bob Hoover strapped to the cabin door.

Oh I do crack me up.

Doubt it all you like. Your doubt won't change the fact that it occurred.
The
aircraft was grounded at some eastern Europe airport with three dead
engines
and it turned out to be feasible and cheaper to fly the plane to
maintenance
rather than bring the maintenance to the plane. I believe it was written
up
in Flying magazine.



Seems unlikely that a 747 could even take off on one engine. Maybe if the
runway was 10 miles long.

He violated 91.13a, careless and reckless operation endangering the life
or property of another, unless he owned the aircraft, the crash site,
and the tree.

In the early days of the 747, one arrived at London Heathrow with one
engine silent. Not only silent, but missing....

I replied via email.. but basically the sketchy details are he
http://www.brantford.com/news.cfm?pa...articleId=4997

I'd say he's going to need at least a couple of new engine mounts.

"brantford.com contacted VanBerlo today but he declined to comment."

Yeah.. no kidding... I wouldn't have even given them my name.
