Twotter 5000kg over MTOW
Just saw a guy takeoff in a twin otter 5000kg overweight! (gross weight about 10 ton). Just did a very wide circuit and came back and landed. Rotate speed 120 kts, struggled to 600ft agl.
I was quite impressed with the performance of the aircraft being able to still fly with that much extra weight!
Just thought some people on here would be interested also by this.
Cheers,
Tiger.

Took one with a very close mate who was even a lot closer by the end of the trip from fiji to kiribati to hawaii and into la.Aircraft at a similar weight. dont like to say too much on here, could be mermaids about. it had two time expired bandit engines on it. hawaii to la 2200nms with nowhere to go. awesome aeroplane. slow to accelerate on takeoff obviously. you could pile all the **** that gets thrown at dicksmith into it and i reckon it would still go.best thing i ever did. not including getting married. stuff her shes gone to bed. it was THE best thing i ever did and come to think of it, i wished i married the plane

Compressor Stall - thank you for your link, you are spot on as usual.
Having had a play around Twotters myself, including a couple of courses with the people in Toronto who made this impressive bird, I am of the opinion that their SIMULATOR is the only place in the world where this kind of thing (flying a DHC-6 grossly overweight), can be done safely.
Soo - a Twin Otter wing can lift vastly more weight than the aircraft is certified for, but - it cannot do it SAFELY, and therefore should not be called upon to do it at all!

I believe there is an approved ferry overload for the Series 300 which was used by a well known Californian company for trans Pacific ferry flights. I can't recall the figures but think it was around 15,500 pound TO weight.
In Canada, the DHC6-300 is approved to operate up to 14,400 pounds TO weight on aerial work ice patrols.
I know a -34 powered Series 300 will fly with a 3,000 kg payload - but don't ask me how I know! 10,700 kg TO weight would be suicidal, not to mention very stupid!

The DHC6-300 MTOW is some 20kg below 5700kg for ease of regularity requirements and also a VMCA and eventually S/E climb consideration. It is structurally built for more than this.
There are many DHC6-300 certified for MTOW 6590kg in a fire fighting role where the excess weight can be jettisoned and for ferry flights even CASA will give a dispo for 7272kg, but the pilots know sure as **** that they are going down if they become single engine.
Most DHC-6 used in a military role have a MTOW of 6363kg.
Tiger 77, I really do wonder if it was actually 5k over weight, almost impossible due to bulk out .

The final MTOW we worked out was 10,823kg. All payload was weighed before it went on. I believe the pilot was keen to finish early so decided to do only 1 trip instead of two. Of course after takeoff he realised it was a stupid idea and came back to offload half the freight (gold bars).
I was quite suprised at him, I thought he would just continue on since he was already airborne.
Lucky the runway was fairly long (2km) since it used most of it.

Afraid I wanna see the video tape on this one...5000kg of gold...why the rush to land? I'd be paying cash for fuel and dissappear off the planet....overloaded Twin Otter Dissappears on flight
I used to work same place as woomera....i can honestly say I have abused Twotter MTOW about as far as it ever has been in normal ops....and NEVER got within a bulls roar of a 5000kg load let alone 5000kg overload.
Me think this one might be 'appocryfull' (sp?)

I have lifted a double load (unwittingly)in a Pilatus Porter (roofing iron) and thought "Geezaz the old tarts a bit sluggish this morning " but put it down to a few too many SP sandwiches the night before.
Thats like a ton overweight.

One wet tropical morning took off in a metro 2 with about 300kg of water in the belly, made me nearly **** my pants as I rotated a little and the nose went very high very quickly while the water ran down the back and the beast just kept on rolling on its mains till I decided a smart choice would be to stop, when said water came forward again then the braking became very interesting.
Lesson: make sure your drain holes are clear.
Tinpis was that one of the good old machines from NZ. Had a mate in similar situation on skis but just dropped of the cliff to get to the strip in the valley.

5 ton was the load of superphosphate the old DC3 would lift and that was quite a struggle for the old girl.
I would pay to watch a twotter try 10 ton.
