L29 Overrun at North Shore NZ
 
Damaged plane removed after runway crash - National - NZ Herald News

Launchpad McQuack 1st Feb 2009 08:02


A large number of fire fighters were at the scene, and had applied foam as a precaution, Mr Phillips said.
I'm curious...does the foam cause any damage to the aircraft and/or engine at all? Is it essential for smother the aircraft "as a precaution" or are the boys getting a little carried away, when the aircraft came to a suitable halt from which the pilot could easily walk away and no leaking fluids etc?

I haven't seen a pic of the aircraft but it sounds like the damage was minimal, happy to be corrected if that was not the case...

there was no foam used. .

Wouldn't NE be a bit marginal for an L29? Even on a perfect day?

6080ft 1st Feb 2009 23:28

I watched that thing do circuits at whangarei on a warm day - looked very bloody marginal there too!

NZFlyingKiwi 2nd Feb 2009 05:30

I've watched it doing circuits at Ardmore a few times - needless to say the initial climb rate seems to leave a little to be desired. The owner has another one, -SSU. Damage doesn't look too bad in the photo although I suppose pictures don't always tell the whole story.

Nobody made me Thread Prefect but...

If I wanted to read an unsubstantiated rant
(I heard....... the rumor was...... probably went thru the firewall cause he was .....)

I really would prefer half-decent spelling and grammar:

1. Try to use complete sentences (the first word generally starts with a capital letter; the sentence is often considered best ended with a full stop).
2. Try to use the words that don't make the sentence nonsense e.g don't use "cause" when you mean "because".

Apart from the English your post was pretty much a waste of bandwidth, better off in Jetblast or R&N.

Did you see the original Herald article? Did you see the picture on it?

http://www.pbase.com/garylowndes/ima...1/original.jpg

:D Only with Aunty Herald - that is not jet powered, it is not Czech made, it is not a military aircraft and it is not all that vintage. (Picture pinched from another forum, but seeing as it's now been changed...)

Only a week!!!!!!!!

Judging from many of his/her other posts one could be forgiven if the time in the Sin Bin wasn't quite bit longer.

"Wouldn't NE be a bit marginal for an L29? Even on a perfect day?"

It would seem so.

Talk to the GBA boys about getting a cherokee 6 out of there on a warm day, let alone a low powered jet. would be interesting to see the performance figures.

sexy time 3rd Feb 2009 04:39

That piece of s**t and it's owner will hopefully go somewhere far far away and not put any one elses life at risk......

Brake failure - yeah right........an arrestor hook wouldn't have stopped that thing!

Yes well, from what I saw he was a bit trollish if I ever saw it, and I've only been here 5 minutes :}

Dairy Flat is hardly the longest runway around. If he was told he shouldn't be trying it, he shouldn't have tried it.

Cypher 3rd Feb 2009 04:54

From what I've heard and seen in a past newspaper article (North Shore Times Advertiser) .. the owner is a reasonably new PPL....

remoak 4th Feb 2009 03:26

Inexperienced rich boys and their toys... the continuing saga...

Slightly off-topic - wasn't the SSS rego worn by a Grumman Cougar? Anyone know what happened to it?

Corkey McFuz 4th Feb 2009 03:42

Yes that piece of junk is now Registered PAP but as of about a month ago has been grounded due corrosion on the main spar or similar and will never fly in the skys of nz again. Thank god :D

mattyj 4th Feb 2009 04:58

Yeah..being parted out on trademe last month..

..in defence of Mattathm..from what I've heard from other sources..everything he said about the owner is true.

..give him a break Mods..he has Tourettes in his fingers:}:}

remoak 4th Feb 2009 06:15

Did my multi Instrument rating in that piece of junk, 20-odd years ago. Horribly underpowered, but it did have a decent flight director and AP, Was pretty spiffy in those days (compared to say a Seneca 1 or an Aztec).

Sorry for further thread drift

Only flew it once, about 9 years ago. Seemed to me to be an OK aircraft especially as a multi IFR trainer, true not over powered, but certainly wouldn't have called it a heap of junk. Amazing how our perceptions differ.

Corkey McFuz 4th Feb 2009 10:29

Without intentionally drifting the thread further, it just ain't worth it's own thread, sorry :ok:

It might have been ok 9 years ago but isn't the best machine around now. Always breaking down, parts are hard to come by so out of the air a lot, things not working, things falling off, shabby this, ripped that etc etc need I go on ??

There would be more knobs/leavers/buttons etc in that plane without their handles/knobs whatever that there would be with them on :uhoh:

And to top it all off, it has been replaced by none other than VH-MEP, for those that know that old chariot :ugh: :}

remoak 4th Feb 2009 10:55

When I flew it, it had recently been refurbished and looked great, inside and out. Great ADI/HSI combo, far better than anything else around at the time, and it was pretty roomy.

Nowadays, you have those plastic things with the diesel engines that need reconditioning after 20 mins... :bored:

Fighter jet jockey won't be grounded
By LIZ WILLIS - North Shore Times | Thursday, 05 February 2009

A crash at North Shore Aero Club has temporarily grounded Abbas Shahroodi’s fighter jet.

The brakes failed on his former Romanian Air Force L29 Delfin on Sunday and he "ran out of runway" and crashed into a fence, says Mr Shahroodi.

Mr Shahroodi, a Castor Bay resident, says he wasn’t injured and the damage to the jet’s nose gear is repairable.

He says his training to deal with emergency situations kicked in but admits he felt a "level of discomfort".

Mr Shahroodi says it had been a great day for flying and while something like brake failure was not unexpected it could happen.

Aircraft are one of the safest means of transport, says Mr Shahroodi.

The fact it was a jet involved in the accident meant it attracted a lot of public attention at the Dairy Flat airfield, he says.

Postmans Rd was closed for several hours while emergency services dealt with the accident. About 15 fire appliances attended. The Civil Aviation Authority is investigating the crash.

Mr Shahroodi spoke to the North Shore Times in January about the thrill of fulfilling a dream to fly a fighter jet at 700kmh.

The speed thrill is greater than any sportscar, said the 49-year-old Gamma Computers director who emigrated from Iran 23 years ago.

"It’s like going downhill in a car when you have lost the brakes," said Mr Shahroodi.

"You cannot fly it slowly. It’s the highest level of aviation experience."

Mr Shahroodi owns two L29 Delfins, which gobble up $1600 worth of fuel an hour, because the Romanian Air Force only sold them in pairs.

This year he hopes to buy a Mig 23 or 29 and fly at two-and-a-half times the speed of sound.

Konev 4th Feb 2009 20:36

MiG23 or MiG29?

hope he wont try them into north shore, yes they are grass runway capable and whatnot but still need a lot of length, especially the 23.

NZFlyingKiwi 4th Feb 2009 21:11

I would imagine that if he does manage to import a MiG it would have to be based at Auckland. As much as I would love to see an airworthy MiG here, I feel the combination of a pilot who is from what I understand reasonably inexperienced on jet aircraft with a supersonic jet fighter may not be the best thing ever.

Cypher 4th Feb 2009 22:43

Hope he has liability insurance!

mattyj 4th Feb 2009 23:38

Mr Shahroodi..we know its a part 91 operation, but now that you have seen what can happen..perhaps some Accelerate Stop calculations for NE might be a good idea.

troppo 5th Feb 2009 00:33

One MIG29 on the NZ register would make the RNZAF redundant.he could play boyracers with the RNZAF but would need deep pockets for the fuel bill.
Do you reckon an Iranian would be able to own an airworthy MIG in the USA?

Peter Fanelli 5th Feb 2009 00:37

So... would this be an "Airline" or an "RPT" issue?

remoak 5th Feb 2009 02:47


perhaps some Accelerate Stop calculations for NE might be a good idea.
He was landing, wasn't he? In which case, accelerate-stop caclulations mean precisely squat. Maybe what you really mean is a calculation of landing distance required, and a factor for brake failure/spoiler failure/flap failure etc.

On a short strip like Dairy Flat, you really have to wonder why he didn't open the tap and go around - he must have hit the brakes almost immediately after landing so would have been aware of the failure whilst still having lots of speed for the go-around.

But then... inexperience... PPL... more money than sense... etc

CI300 5th Feb 2009 05:27

He wasnt landing, he did that a few months back. He was practising/trying to get out. Mattyj knows the score.

philipnz 5th Feb 2009 05:30

L-29.Org - Latest News

Lots of good stuff there in the manuals including little gems like reccommended strip length 3000feet and spool-up time from idle 14 seconds. Suggests you don't idle on final/touchdown :=

remoak 5th Feb 2009 07:51


He was practising/trying to get out
Practising WHAT exactly? Takeoffs? If that is the case, he has to be the most stupid rich idiot on the planet!

Funny how brakes stop working after repeated accelerate-stop events...

mattyj 5th Feb 2009 19:17

Insha Allah:ok:

Steve Zissou 5th Feb 2009 21:47

It seems Mr Allah wasn't willing mattyj. Whatever happened to mattathm and who in fact is he? I heard a rumour he 'was' sending his comments from Paremoremo prison. Seems that has all come to an end now...:ugh:

ZK-NSN 6th Feb 2009 06:42

Has the aircraft taken off from NE before or what?
Are the owners of the airfeild just going to let him fix his toy and try and again?

"Aircraft are one of the safest means of transport, says Mr Shahroodi." but once he has finished with it, car surfing will have better safety stats.

"The fact it was a jet involved in the accident meant it attracted a lot of public attention at the Dairy Flat airfield, he says." I can see the new welcome sign now. Dairy Flat "NZ home of the jet crash"

Make it easier for everyone buddy, start using your head or update your dental records.

Stifmeister 6th Feb 2009 06:55

Remoake, clearly you have no jet experience.

Upon landing at nth shore the short strip it is, in a POS backwards jet with the taps closed, once it touches down (which i gaurantee wouldnt be at the start of the strip with mr kjyasdvka at the wheel:\) it would be at about 100kts (guessing) and by the time the exceptionally experienced pilot that he is on his ppl licence:ugh: keep it straight down nth shores 1m wide runway and opened the taps for a touch and go as you put it, and the engine finally spooled up to t/o thrust with his head in the cockpit not over reving or temping the engine because of course it will be a full fadec ecu and watching the asi and keeping it straight as it slowly accelerated uphill............

I mean cmon man, its a no brainer for some.

I mean brakes failed?
Who uses brakes on a takeoff?

Unless of course he realised 1/2 way down the runway it wasnt gonna get airborne, so he aborted and broke the brakes cause he was pushing them thru the firewall to stop the plane.
baahaahhahahahahahahaa

remoak 6th Feb 2009 09:32

Yeah I've only been flying jets most days for the past 20 years... :ugh:

Since you clearly know nothing about the subject, let me just say that a turbojet engine is quite capable of spooling up quickly enough to get an aircraft that is already at flying speed, safely back into the air. Even from ground idle. In fact, it is often demonstrated during certification.

Again, if you knew anything at all about the subject, you would know that it is SOP in a non-FADEC aircraft to have a clear idea of where max T/O thrust is on your power lever. We even used to mark it on the quadrant on some jets I flew. Adjusting to an in-limits temp or RPM then becomes a quick glance and an equally quick adjustment. If you know what you are doing, of course.

You don't use brakes on T/O, unless of course your engine just quit - right?

If he really was practising takeoffs, he probably overheated his brakes. Doesn't take much.

Anyway you have made enough of a fool of yourself, now off you go back to your MS flight sim...

mattyj 6th Feb 2009 19:14

Baaahahaha...I warned you about him stifler!!

"I just got peed on" :}:}

NZFlyingKiwi 6th Feb 2009 22:22

The CAA accident report out now says that the aircraft left the runway during a "high speed run" - clearly not landing, and suggests not necessarily trying to take off either, although one wonders what exactly the purpose of this run was?

Here's the link, the second one down: http://www.caa.govt.nz/Weekly_Accide..._02_Feb_09.pdf

framer 6th Feb 2009 22:49


unexperienced.
Shame your instructors at Nellis didn't teach you a little grammer

Forthly Touch and goes wouldnt use much brakes at all
Plenty good England bro.

But on a more technical matter

Id say it would be 5 minutes at least so the brakes would have a chance of cooling down from the last landing
Really shows your level of understanding with regard stopping an aircraft. I think it may be the stupidest statement I've ever heard from a pilot, in fact, I hope you're not a pilot with ideas like that rattling around in your head.
Regards, Framer
