Had some friends from the Naki staying for the weekend. They came up to see "War of the Worlds".
We have had a common interest in aviation for years (including the ladies) and since Saturday was fine, we nipped out to Ardmore to see what was happening around the Warbirds hanger.
Typical fine Saturday and the airfield was pretty busy. I have always found people out there to be pretty approachable and happy to talk aircraft.
The first thing that I learned was that you can go for a ride in the Cessna Dragonfly but it will cost you about $1500. I am seriously thinking about finding the money. The Dragonfly was used as a ground attack aircraft in Vietnam and so the engines are full military spec. This means about 5 minutes to Hamilton and $800 worth of fuel in about 20 minutes.

Anyway, we had no particular expectation and so were delighted to discover that Avtech had rolled out their latest restoration project and were planning to test fly it.

It is a Mark five Spitfire.

It last flew in about 1945.

The mark five is particularly rare with only a handful of complete examples worldwide and I don't know if any of the others are in flying condition. Keith Skilling was the test pilot and those of you who follow vintage aircraft will know that he also displays the Alpine Fighter Collection Corsair.

The workmanship was nothing short of superb.
Looking along the top of the wing, one sees thousands of flush fitting screws. The blade slots were all aligned FFS. The attention to detail was awesome.

The engine was ground run several times and started easily. There was a small problem with an oil leak from a supercharger seal but it was not enough to prevent the test flight which went ahead at around 4 p.m. Nothing compares with the sound of 27 litres of Merlin in full cry.

The right hand undercarriage leg failed to retract completely and so the flight was limited to a couple of circuits and a landing on the grass strip. The gear extended again just fine. The most likely cause of the problem is air in the hydraulic system. It is hard to eliminate it completely from a total stripdown because the engine (and so the hydraulic pump) cannot be run and the gear cycled with the aircraft on the ground.

The next flight is scheduled for this morning. I was very tempted to pull a "sicky"

It is owned from the USA and so sadly will be heading Stateside as soon as testing is complete. The owner has invested about $US 3.5 million in this restoration.
IMHO it is a real tribute to NZ skills and abilities that the work was done here.

awesome stuff! did you get any photos?

ive always had a small interest in planes, amazing things really, specially the war vets! $1500 aint a bad price either, for a flight in a plane like that, be something youd never forget.

Ah, yes it can. There are normally, very extensive, gear tests on the ground with jacks placed under the wings to get the wheels off the ground.
Presumably just a small glitch!

Pacific Aerospace or Avtec? Both of these companies turn out magnificent work and are renown for their P-40 rebuilds.

Yup. There is nothing better than a Merlin-powered display!!!!

I'm repeating what the guy who did the hydraulic work told me.
Apparently the connectors to the pump are a problem. They are easy to use but introduce air when disconnected.
I agree that there are extensive ground tests but they usually use an auxilliary pump of some sort. I wouldn't like to be around if they ran up the Merlin with the aircraft up on jacks and as I understand it, running the engine is the only way to drive the on-board pump.

I didn't have a camera with me and so didn't get any picks. However several friends were clicking away madly and so I am sure I can dig some up if anyone is interested.

It was Avtec. They currently have a P 40 and (wait for it) a Mosquito in the workshop.
I didn't know that Pacific Aerospace was into restoration as well. Had only heard about Avtec and Pioneer.

NZ seems to have more than our fair share of pilots, plane builders and flying fanatics. It's a bit like the boat-building industry. For a small country, we have a lot of expertise. Most families seem to have a pilot or two in them.

My Dad was a pilot, so was my brother. Dad used to fly a Tiger Moth across the South Island in the 1950s when the industry was heavily regulated and controlled by the government. He broke all the rules and became known as the Parenga Pirate for his antics. He was also a parachutist so you can imagine he had a lot of crazy stories to tell.

My uncle and cousin built their own plane but my cousin crashed it and died (several years ago now) :( Nothing to do with the plane - purely pilot error :(

One day when I'm rich I'm going to take up recreational flying. :)

I think motorcycling and flying and/or parachuting probably attract similar kinds of people.

My bad! Pioneer.

If you have piccies, post them up!
