View Full Version : 737 tailfin weight

20th Jul 2011, 22:21
Does anyone on here know how much the tailfin fron a 737 300 to 500 might weigh without the rudder.
A curiosity question for an artist friend.

Google is your friend....

not this time...I looked and found nothing.

it's 12m High that I know of and guestimating (based on no knowledge whatsoever) it is 3-4 tonnes (new money)

For removal/installation of the vertical stabilizer a crane capable of lifting 2400 lb / 1089 kg is needed. This is for the entire assembly. With the rudder and other bits removed it will of course weigh less.

there goes my theory!

SoundBarrier guess...BUSTED.

Um... lifting...

I'm no Boeing driver, but there ain't no way that fin is that kind of high. The whole airplane (original 737) is only 10m high or so, and the fin's maybe a little more than half of that, an area of maybe 40m2, maybe 25kg/m2... call it a tonne and a bit.

N707ZS: Did you use the term Tailfin so we would not confuse it with a fin on another part of the aircraft ?

727 had a tailfin.

Near the beginning of the moving line, an overhead crane lifts the 23-foot-high (7-meter) tailfin into place so it can be attached.

Trident 1 tailfin with intake.....no rudder was 2.8 t. This was also without horizontal stabilizer.

Thanks for the replies a little bit of help. With the current price being around 90 uk pence a kilograme it might work out just a bit expensive.

A curiosity question for an artist friend.

With the current price being around 90 uk pence a kilograme..

Is that how much artist paint costs, or the price tag per kilo for
lifting a 737 rudder off its mounts?

...........and there was me thinking it was postage. :hmm:

tail is 11.28mt from ground to top of tail (not just tail height)

I'm still trying to correlate the weight with artistic impression. :confused:

Um... lifting...

One infers that the artistical friend wants one (ea.) 737 fin upon which to perform mixed media work.

Of course, if aforementioned can find said art object, then must either:
a) cajole and persuade the current owner to surrender said object or;
b) pay for it and;
c) relocate it

For every tonne the thing weighs, the value of said cajoling or persuading or paying increases by a value of Ģ900, if I do my sums correctly, and the cost of shifting the thing also goes up as well.

It would seem to come down to whether the current owner of this hypothetical fin would prefer to be obliquely immortalized in aviation-related mixed media, have 900 quid, or some pro-rata amount of each.

I didn't even have to get out of my chair and I came up with the same figure eyeballing a photo of a 737.

FlightPathOBN -- I think those are dorsal fins, not tail fins.

Well...they are Trident...
