|
|
After spending a good few weekends behaving like a contortionist
poking wires through tiny holes and threading power cables and aerial
leads into virtually inaccessible places in Dorothy's interior, it was
a relief to finally pack up and depart to the nor-noreast on track for
Broken Hill about three weeks ago (Wednesday, 4th April, to be exact).
Since then we have covered 2736 nautical miles at an average speed of
91.4 knots. We used fuel at a rate of 34 litres per hour- a rate which
caused us some concern and will have to be investigated as it is about
4 litres per hour above Dorothy's usual fuel consumption. The engine
never missed a beat. The radio worked beautifully, save for one minor
hiccup which was easily diagnosed and fixed.
We flew over an incredible variety of country- from red sandy desert
between Broken Hill and Bourke, to the grey/green "Channel country"
around Charleville and Longreach, the tropical mangroves and estaurine
environment from Rockhampton to Bundaberg, the industrial quagmire
near Gladstone, the structured chaos of the canal developments and the
high-rise around the Gold Coast, the twisted mountains of the great
divide, and the endless plains of Western NSW and Victoria.
The weather was mostly kind- as is evident from our average speed, we
had tailwinds most of the way, with Longreach to Rockhampton being the
main exception (65kts ground speed for a while!). We mostly had blue
skies with a few puffy clouds- the only exceptions to that were an
800' cloudbase as we left Caboolture- and flew across Moreton Bay!!-
and a dose of fog that kept us on the ground until 10:00am at
Luskintyre in the Hunter valley.
The drought was evident almost everywhere we went. It was most obvious
in the outback, of course- I have a photograph of the Darling River at
Tilpa (about halfway between Wilcannia and Bourke) which shows a dry
bed with a few puddles in it. They must be having dust baths. I have
just compared it with an image from Google Earth which shows a river
full of water. But even usually lush green places like the tropical
coast of Queensland had a brownish tinge that I've not seen before.
There was one exception- Kempsy, NSW was green (the locals disagreed)
and we had 12 mils of rain from a thunderstorm while we were there.
We had one "adventure": Enroute from Longreach to Emerald we had
planned to top up our tanks at Barcaldine, but found the wind too
strong and the presence of tall trees upwind making the air too
turbulent for a safe crosswind landing. We pressed on, calculating we
could make Emerald with sufficient reserves. But the wind
strengthened, and as we progressed it became obvious that our fuel
margin was diminishing. Shortly after we passed Alpha my calculations
showed a margin of just 15 minutes (with over an hour still to run)
and I knew we had to find another solution.
The Alpha strip was 18/36 and the wind 080 or thereabouts at around 25
knots. We took a look at the strip a couple times, but the angle was
clearly too much for a safe touchdown along the strip. However, Alpha
looked like it used to have a cross strip. Although it was now well
overgrown, the area where it had crossed the new sealed strip was
clear of trees. We took a close look at it from about 20 feet up and
decided that it would do as an overrun area (provided we avoided the
star-dropper we spotted on our inspection runs), so we decided to
carry out a short-field approach directly into wind angled across the
strip towards this area. We lined it up and used full flap at 35 knots
with plenty of power. I got Dorothy onto the grass at the edge of the
strip , she skipped once, and as she touched the second time I dumped
the flap and stood on the "influencers". We stopped about 15 meters
into the grass on the other side of the runway- a total distance of
about 50 meters and certainly the shortest landing I have ever made.
We shut down and dragged Dorothy back onto the runway before
restarting and taxiing up to the little terminal building.
I checked the phone book and rang an estabalaishment called the "Alpha
Gateway" hoping it might be a servo, or failing that, a pub. The
conversation went like this:
"Er, hello, do you sell petrol?"
"Well, yes luv, on some days, but today we have a special on combs..."
"Er, what is this place?"
"We're a servo, luv, and general store"
I explained the situation, and the lady arranged for "Col" to pick us
up and bring us into town. Col arrived in about 15 minutes and took us
into Alpha where we met the owner of the store- Glenda, the one with
the sense of humour. She and Col had recently taken over the store
from an old chap who had never cleared any of his stock. If you are
looking for a set of points for an MG Midget- you can get them at
Alpha. She had 180 combs she was trying to sell (we bought two) and
she also tried to sell the Navigator a pair of ceramic "Dust
Dolphins". We collected our fuel and before taking us back to the
airfield Glenda showed us around the town of Alpha, pointed out the
various flood levels, and explained how she was working on developing
the town's infrastructure. She certainly gets our AAAA seal of
approval, and if you are passing that way, say hello from Dorothy and
her crew. Its people like this that make Australia a fun place to
live.
About 20 miles from Emerald we were startled by a terrifically loud
buzzing noise emanating from the starboard wing root. After the
initial burst of adrenaline, I realised it was a loose tape vibrating
in the wind, and of no consequence apart from the noise making it
difficult to think, let alone use the radio. At Emerald I had to cover
the mic. with my hand while I made my calls or nobody would have been
able to hear anything except the buzzing. I found what I thought was
the culprit and sealed it with some gaffa tape, but during take-off
the noise started again, so we landed for a closer inspection. This
revealed that a gap seal between the canopy and the wing root had
lifted in the middle and was vibrating like a harp string. This time
we used a wide strip of self-adhesive sailcloth as a temporary repair
and that fixed the trouble. Unfortunately, the extra time put us too
close to last light, and we had to stay the night.
Within minutes some local Emerald aviators had offered Dorothy a space
in a hangar for the evening, and a lift into town.
We were met with tremendous hospitality wherever we went. From the
gruff "RT" of Rockhampton (who directed us to the best Barramundi meal
we have ever had, loaned us his car, and hosted us like royalty) to
the gents at Kempsy who have already restored two Austers and are
working on another (I took part in their club's streamer-cutting
competition with very forgettable results). At Luskintyre we slept in
their beautifully appointed clubhouse for a very modest fee, and at
Broken Hill we were entertained by two delightful grandchildren of a
AAAA member.
The Navigator did a fair share of the en-route flying on this trip,
including the run through "the gut" (the VFR route from Wirradgurie to
Maitland) which she thoroughly enjoyed. Her navigation skills have now
reached a high level, and we marked all of the airfields we saw on our
charts for future reference. (But she still can't find her glasses
when she needs them....)
The AAAA fly-in at Echuca was well-attended. There were 18 Austers and
about 150 aircraft present when we left on Sunday morning, with more
arriving as we were departing. The Grand Champion- a beautifully
restored Stinson Reliant- was a popular choice. The organisers had
done a sterling job in laying out the aircraft parking so that both
pilots and public were satisfied, and the rest of the organisation
appeared to be going smoothly.
"Dorothy" will be getting some attention before our next excursion.
The fuel consumption issue has to be solved, and I have gathered some
ideas on how to reduce her oil consumption- primarily by reducing the
amount scattered across the countryside by her various vents and
drains- which I gleaned from the owner of a Dragon. He's got two
Gypsies to worry about, so he should know .

Great write up Coop. In a bored moment I took your route and plugged it
into my home made Excel flight planner, ( after having to input coords for
about half of your waypoints from ERSA and AOPA airfield directory and
searching all over for this Callington place - which i guessed to be 35 deg
7min S and 139 deg 3 min E using Adelaide VTC- is this your backyard or
something?). You sure covered some country there! I got your total
distance as 2651 nm ( Is the distance you quoted from what you measured from
maps or just what your GPS measured ?). I noticed your longest leg (
Callington to Broken Hill) was 223 nm or about 2 hr 30 min flying time, with
most legs being less than 2 hours. I am guessing Dorothys range is a lot
more than this but you just like to break the trip up a bit?

I go with the other advice that it may be the prop but if you are using
mogas not avgas a 10% increase could be ethanol. |

mitch, who for years illegally maintained his aircraft, found a
solution to the oil problem.
it lies in the use of the latest technology truck piston rings.
trucks have rings of the size you need.
they require the ring slots to be remachined in the pistons because
they are wider than aircraft rings but mitch found that the new
metallurgy really does the trick. his gypsy minor engines dont gunk up
the aircraft with sprayed oil and dont seem to be adversely affecting
cylinder wear.
the technology of the rings has some mickey mouse name that RT would
probably know. what mitch found is that it works.
.....of course people who follow the casa route will never improve.

Not true! We only get nose bleeds above 1000'...... (Any higher
than that and we suffer from terminal vertigo.....)

At startup she now belches out

Mmm - didn't comment at the time because I was so astonished - then

Coop'd spent the whole 2 days while it was tied down at Rocky cleaning
it -
but I have *never* seen a Gypsy so dry on the outside. For the kids,
Gypsies were made in the same UK factory that made Pommy motorbike
engines.
Pommy motorbike engines were always glistening with oil leaking from every
pore - like Gypsies.
I confess we did give her a good wipe down after arrival at Rocky.
However, her leaks are a bit less than some others, and the white
paint on the firewall also helps to make her look cleaner.... :-)
Far as Dragons go, he'd more usefully spend the time looking after the
props. The story goes Examiner of Airmen Tom Drury (based in Bris years
ago) was in the RH seat of a Dragon that slung a blade into the cockpit,
taking off the leg of the pilot.
Ouch! That must have stung a bit. Des has already had one engine go
off song with a stuck valve. I'm sure he checks his props regularly-
the rest of the aircraft is a delight to look at- very well rebuilt
and maintained. He's an engineer, you see.....
You can see his aircraft here:

Schmick-ther-duck! And you can see where a prop blade would go if slung...
Only been in a Dragon (or maybe Rapide - dunno) once when Dad wangled a
cockpit visit for me in the mail plane at Tennant Creek ca 1950........

We actually run non-detergent oil at present, because this is what was
being used when we got the aircraft. Detergent oils are approved for
use in Gypsy engines, they keep the engine cleaner, and they are much
more readily available around the traps. We considered changing over,
but the risk is that the accumulated sludge (from using non-detergent
oil) will be released in big lumps, blocking the oil galleries and
chewing out bearings. Others have changed over without problems, but
there is a risk.
When our engine is overhauled and all the sludge is cleaned out, we
will run it in using straight mineral (non-detergent) oil and then
change to the detergent oil. This is the recommended procedure for
changing over to additive (detergent) oils in engines which have been
using non-detergent oils for a long period of time. (I've done about
600 hours with this engine, all of it on non-detergent oil).
I have spoken to engineers who work on these engines and they tell me
that the sludge build-up from prolonged use of straight oils can get
to the point where it almost blocks the holes on the inside of the
crankshaft journals- these are quite big (about an inch in diameter, I
think).
