210 down near Numbulwar?

Heard the mayday over center this morning, engine trouble over rough land looking to put it down in the trees.. Doesn't sound good...

Dornier and several other planes searching the area this afternoon, any news?

Hoping all are well

Word is 2 POB, Both survived with injuries but managed to walk away and evac'd to Darwin for treatment.

Details are sketchy but for sure very well done by the pilot to get a result like this in a difficult situation in a very unforgiving part of the country.

Great news for a change from a bad situation. Keep clam and wings level and fly it all the way....

Glad to hear that result.

Great news! Good job to the pilot!

Also a big shout out to the guy relaying in UZO, calm and concise while one of his coworkers was in peril, great work mate!

If the bloke in UZO was one of his coworkers, it'll be a Katherine Aviation machine I think.

If I remember correctly, that is a harsh area.

Very close to the water though
Not wrong there. Unless he was coming in from Groote he'd be over the trees. Not too many places I'd want to try and put a plane into.

Good to hear they got out alright.

What a scary scary place to have to put an aeroplane down. There is no roads or flat land at all out there, and to have managed to walk away from a wreck like that is simply incredible! Every landing you can walk away from...

Congratulations CC, you did well.

Also a big shout out to the two in UZO and YDU - both of you remaining calm and methodically searching the area until you found her. I can't imagine what was going through your head, but to keep it going so professionally until you had positive confirmation that they were alive - to both of you, too, well done.

I thoroughly endorse what Lasiorhinus said. Top effort by all involved.

Having flown there more than a few times it is not a place to have an engine problem no matter where you are coming from.

Have any details emerged as to the cause of this event?

My brother and his mates flew that 210. I've had a few rides in it, the boys liked the extra "go" it had. But that was 20 years ago! Amazed it's (was) still around....

On that one day that pilot was the best pilot on the planet.
No ego
No pretending
No bullish t
Two people lived when the universe conspired against them.
My hat off to you.

The engineer reported that, although the aircraft had been using oil at a higher rate than previously, the compression testing performed at the last 100-hourly inspection indicated that compression was within tolerances.
The engineer had advised company pilots that, rather than flying at higher altitudes, with higher engine revolutions per minute (RPM) settings and a MP of about 21 inches Hg, it was more desirable to remain at a lower altitude where 23 inches Hg could be achieved.
Oil consumption going up, directed to fly power settings that would produce slightly higher than normal peak pressures, and most probably a lifetime of running at slightly ROP settings creating maximum force on... the.... Conrod! C'mon ATSB isn't anyone in there curious? We've been building these engines for over 50 years really shouldn't be breaking conrods anymore. Unless for some reason these engines are actually very strong but are getting unknowingly abused...

Is there evidence that supports the implied assertion in this report that low rpm / high mp will reduce oil consumption versus high rpm / low mp?

The ATSB really should elaborate on why the conrod actually broke. Instead they've left a lazy comment that reads 'The engine failed due to a broken conrod'. A life of operating at 70% power at 50degROP and climbs conducted at 25/2500 took its toll on this engine. As Lumps mentioned, these engines are very strong thats why most of them last but you'll get one that doesnt (100HTR, nearly buddy, nearly!) and it ends up becoming involved in a completely avoidable accident.

I saw the pics when the aircraft was retrieved. It failed down around #1 and 2 cly and lifted both mags out and onto the case
Nasty hole in the top of the case.

Cheers

Investigation: AO-2014-059 - Collision with terrain involving a Cessna 210, VH-HGZ, 50 km W of Numbulwar Aerodrome, NT on 28 March 2014

I thought the Airvan report was a complete and utter embarrassing disgrace. This one makes the Airvan report look like a technical masterpiece.

ATSB........either get some experts or get out of the business.

What waffle.

JD......you wanna start up articles again mate?

Oil consumption

"Is there evidence that supports the implied assertion in this report that low rpm / high mp will reduce oil consumption versus high rpm / low mp?"





Low rpm/high mp increases radial tension on piston rings reducing glazing and subsequently oil consumption.

Atmospheric engines that have been ferried across the Pacific on delivery tend to have higher oil consumption in service, this is due to the low mp at high levels during delivery and reduced radial tension on piston rings and cylinder glazing during the important running in phase.

Older Catepillar Diesel engines are notorious for high oil consumption if the engines are not loaded up, in fact the old 12E graders had a placard in the cabin stating not to "baby the engine".
If they were operated at low power settings for extended periods of time, accumulated engine oil would stain the exhaust stack.:cool
