Just thinking further on that, here’s another possible scenario.

Because of the high price of fuel, the workshop sets the engines for absolute leanest burn allowable by the manufacturer, but after a longish period on descent at a low power setting, the engines fail to respond, an unanticipated consequence of the lean setting in these conditions on this particular day.

I seem to recall reading about this happening to a 747 in less pressing circumstances, but they had time to eventually get two engines going again and land safely.
If I was an investigator I’d be interested to know if this was the first attempt to spool these engines up subsequent to the aircraft’s descent into LHR.

The engines and electronics on that aircraft type have such a history of reliability, and there is so much redundancy, that it seems that a failure of one of those systems is unlikely.

Pilot procedures also are honed to a very reliable sequence so except in v. unusual circumstances it would seem an unlikely cause.

I’m wondering if one of the procedures in the circuit is to switch to a fuel tank that is as yet unused, in which case, with Beijing as the departure airport, the possibility of contaminated fuel seems plausible, and would seem to account for what happened.
‘Engines roaring’ observation of one passenger could be engines trying to run with incorrect or contaminated fuel.

Roger
no, they were sent to me by a friend who is also a flying boat enthusiast.
I’m not sure of their original source.
The noise must have been quite inspiring too I’d imagine.

Fabulous stuff.
How did you construct – is it as original from old drawings or been made “as near as possible” from photos?
Whichever the end result is wonderful and look forward to seeing your future projects.

Roger, I had a DH side view, and a real DH9 wing, and a bunch of good pictures, so it’s a combination of all those. Construction of fuselage is by substituting steel tube for wood, and fibreglass panels for plywood.

They (predictably) end up quite heavy in the tail, although the DH50 may be more balanced as we are using the real Puma engine.

The next project for QFOM is a DH50 “Iris” for which we have an original Puma engine (2) and propeller, two original wheels,and an original radiator with shutters.
Also on our list is a DH86, Armstrong Whitworth FK8, and Be2e, so lots to look forward to.

thanks for your comments.
If you think people might be interested I will make a thread with the DH61. It’s a while since I made it but I think it’s an atmospheric addition for the museum and gives a link with the past.

Hi John
Quite a resemblance!

I wonder about those smallish, round, finless rudders.
They appeared on the Avro 504, Fokker Eindecker, lots of Neiuports and a host of other aircraft. I wonder if they suffered much from yaw instability.

yes and the lengthened nose must have made that worse.

I imagine a decent fin would improve the Baby’s handling, but then it wouldn’t be an Avro Baby any more.

Hi
Plans for the Avro 534 available from Len Whalley at http://myweb.tiscali.co.uk/aeroplans/index.html

There are two sets of plans, one for a short nose and one for a longer (230mm) nose version. Hinkler’s aircraft, currently in the Queensland museum in australia, is the later long nose version, converted by Avro in ~1920 from the short nose version I think.

This is an interactive display. Wings are frp from a fibreglass mould taken from a fabric covered wing I made earlier, similar to my DH61 replica.http://www.airwaveyachts.com.au/Aircraft/QANTAS%2017.JPG
Controls all work.

The Bert Hinkler Museum is currently under construction in Bundaberg, Queensland, Australia.

Hinkler flew this aircraft from London to Turin, and from Sydney to Bundaberg, in 1921.

Any ideas on where there might be some drawings for this aircraft?
I have to make a replica DH86 for the QANTAS museum in Longreach.
