Flying in it's self has all sorts of risks, calculated risks. If you don't wanna fly single engine turbine IFR than don't. Maybe we should ban departures during migration season as well, look at what happened in NY.

Amen to that! I flew PC12s up north and loved it. I wouldnt trade my P&W PWC308C rockets in for it, but I still loved the airplane.

No I was not young and dumb I was the chief pilot for the company and also involved in the mechanical work done on said engine.

WOW!!! Now Cat you scare me!!!
It doesn' t look like your and DOC's ususal advices concerning safety...

Really, two catastrophic failures? Fly a PC12 Cat, much safer...

Gee Cat...sorry I asked. I was just wondering, after all the Cat hours you logged, how it's engines where. I should have known this ego packed forum would pounce if something in an answer appeared 'wrong'.

DONT LET CATDRIVER GET INTO A PC12!!!!!

he will have an engine failure for sure!!..... who gets into a plane knowing that they will have an engine fail on them in flight?

Catdriver does!!!

I pay more attention to . comments these days than Cat Drivers dribble!!!
Its a shame that Cat is the number one poster...maybe he should go on holiday and let his wife use the computer!!

jetflightinstructor · Post by **jetflightinstructor** » Fri Mar 20, 2009 6:17 am

I did many test flight in my previous company. Never did a test flight on an airplane I knew the engine will fail.
Sorry Cat but for once you will have to admit you did something wrong and unsafe.
You keep telling the other posters they are wrong, this time it is you. Not big deal. Everybody makes mistake in their career, even the stubborn individuals.

And don' t use: I survived then I was right! Because many dumb persons survived on earth.

One last thing, if it was a new poster making the same comment as yours, you will be the first one to jump on him telling him he is not safe.

Wow, I answer a question for someone here and low and behold the anonymous posters crawl out of the woodwork and parse every word I write in an attempt to make it look like I was real dangerous and a high risk taker during my career.

Gee Cat...sorry I asked. I was just wondering, after all the Cat hours you logged, how it's engines where. I should have known this ego packed forum would pounce if something in an answer appeared 'wrong'.

Not to worry Bushav8er I answered your question in the best manner I could, however every once in a while one chooses words that can be used by others to tear apart the message as happened in this case.

Here is what I said:

I have had two catastrophic failures on the Cats, both were kind of expected and both were on engines that we had serious mechanical problems with.

I did not say I deliberately flew an airplane " Knowing " the engine " would " fail on that flight.

I said I kind of expected they might due to my concern that maintenance had not found the underlying cause for the engines showing signs of internal problems.

So here is what I will do from now on, when you have a question about flying airplanes and trouble shooting their mechanical problems just ask the experts on here who feel I am not a good role model, just scroll back and choose which anonymous poster you think is your best source of advice.

And before any of you hero's start jumping up and down accusing me of whining and crying because I got caught using the wrong words in a post fill your boots.

Just remember most of you have a very long road ahead of you until you have flown as long as I have and survived without ever smashing one up...or getting violated by the regulators.

Actually I am happy this happened because I was getting tired of this forum anyhow so to you guys who are experts hiding behind made up names I want to thank you for giving me the perfect reason to turn all this advice giving over to you.

HighBypass · Post by **HighBypass** » Fri Mar 20, 2009 7:58 am

I actually cant belive what I'm reading. (and that I have time to bother replying!!) the discussion regarding the radial should have stopped with .'s comment and we could have moved on to more enlightening things. For all those who are questioning the almighty Catdriver I have a question:

How would you test a freshly worked on engine that maintenace has be slaving over for a few days in an effort to get back into service??

Let me paint a picture of the Events, and possibly Cat can correct me on any incorrect assumptions or misinterpretations i may have made.

The AME's followed the P&W manual and have added several new parts. Now they hung it on the aircraft, poured a bucket of oil in and its ready to rock. Cat is the CP, and is involved with the process, maybe he helped tighen some nuts on it too? (we wont go there). Maybe he lockwired a penny on the bottom forr good luck? Anyhow to the best of everyones experience (from the AME's point of view who will have to sign the logbook saying the engine is now airworthy), everything is tickety-boo, and it is good to go. They followed the manual. what more could they do? (however Cat doesn't like this particular engine, and has a bad feeling about it, but try telling that to an AME! After they've just spent days on it!)

Cat is obligated to do a ground test run, (since he's the CP and wass helping them with the whole thing anyways).

Ground tests are successful.

Now the rings on the new cyliders added need to get seated properly before they get the max compression they were designed to do, this will take a few hrs of normal operation.

Lets go flying! It's just the next step in the process. Sure Cat may still be skeptical about the engine, but maybe he took an AME along to monitor the gauges, another set of eyes to watch things. After all they had worked on it for a few days (maybe a week) and are very interested on how it's going to fare.

They go for test flight, and engine fails. They are over airport at safe altitude and land without further incident.

Am I missing something? Seems like this kind of thing happens all the time to me. Sooner or later your gong to have to take it flying wont you? Or did the engineers put all the time, company spend all the $$ on new parts just for the thing to be a really heavy ornament on the wing?

Thats how I see it.

Rubberbiscuit · Post by **Rubberbiscuit** » Fri Mar 20, 2009 8:21 am

I agree with Teacher.

If we are to prohibit SEIFR, especially A/C using an engine as reliable as the PT6, then IFR in twins that won't fly on one engine close to full gross weight or on a hot day must be banned from commercial air service use as well.

Exactly.

Thats how I see it.

You have explained it very well, both events took place during the normal legal trouble shooting procedures that all holders of operating certificates are required to follow.

Cat is the CP, and is involved with the process, maybe he helped tighen some nuts on it too? (we wont go there). Maybe he lockwired a penny on the bottom forr good luck?

There is no reason you can't go there. Many pilots work in both the flying and maintenance end of the operations, I personally prefer the mechanical part of the flying business....thus my feelings that the problems had not yet been found in those two instances......however unless you do a run up and test flight you no longer have an airplane you have a lawn ornament.

Thanks for the support highbypass, I am sure you can understand why I feel I have reached the point that I will leave all the advice giving to the experts here.

teacher wrote:Simply put if we were to ban SEIFR in factory built aircraft in commercial service due to the risk we would have to ban float flying. There is NO comparison when it comes to risk and loss of life. There is a huge difference in the type of operation but risk and safety are the same regardless.

I don't think I agree with this ... of course, it all depends on training and experience but ... when you have an engine failure SEIFR, finding a good place to glide down is likely to be near impossible and post-impact fire is a huge added threat to life and limb. Not so with floatplanes.

ScudRunner · Post by **ScudRunner** » Fri Mar 20, 2009 9:15 am

Cat, The only reason this turned into this hair ball about flying around in a plane you knew was going to go bang, was that it was not clear in your original story that you where on a test flight. It could have been a simple answer after I threw the "WTF Over" seeking clarification.

What I take exception to is how you jumped on me with your "how dare you question me response" which was completely uncalled for and way out of left field.

As everyone can see on this public forum others misinterpreted what you where saying as well, Trust me we all value experience and everyone's input into this forum.

No problem .., this vehicle of communication on a keyboard is not a natural way to express ones thoughts and emotions flare because we all write and read things different.

I think I'll just try and post less because it is like driving your car between a gang gun fight, sooner or later you get shot.

anonymity · Post by **anonymity** » Fri Mar 20, 2009 9:33 am

Trying to tell AME's what you think is wrong with an engine, sometimes it's like you're trying to tell a brain surgeon where to cut. they won't listen. I snagged an engine one time and even suggested what I thought it might be. Not being an AME, my opinion was meaningless to them, the funny thing was after 3 days of trouble shooting to no avail they tried what I suggested and voila problem solved. I didn't have to say anything, they all ate crow. Sometimes experience can help trouble shoot a problem, but the us verses them aspect gets in the way.
Therefore CAT had no choice but to fly the thing and hope he was right, and fortunately it failed on the test flight and not the 1st flight after the testflight with a gross load.

jetflightinstructor · Post by **jetflightinstructor** » Fri Mar 20, 2009 9:43 am

Alright Cat, what you did was safe you were right. You took the good decision. And that is why you feel intilted today to say the PC12 is unsafe.
Everything makes sense. Everything is fine.
Whatever you want.

Seriously, if we are against the PC12 to fly in IMC, we will have to be against almost all the twin piston flying IMC and regularly crashing.
What is the safest as a passenger? Taking C185 or a PC12?
And don' t tell me they don' t have the same purpose. Because we are speaking about safety, human life here.

This focus against the PC12, as soon as there is an incident is ridiculous, while we don't comment that much on daily incidents occuring on other kind of airplanes.

anonymity · Post by **anonymity** » Fri Mar 20, 2009 9:57 am

Alright, so 99.999 percent of the time it's safe, my house is a 5 mile fix for a runway and that .001 percent it happens and the pilot is doing his best to make this runway but breaks out at 200' just east of my house with about 3 secs to react.Is that a road nope shit. Now I wake up or don't with a pc12 nose coming through my roof. Safe sure most of the time, safer than a twin I don't think so. If you fly a navajo within the limits you will make it to an airport with the second engine, now that depends on variables like when it quits and how soon you feather it and piloting but if it were not the case it wouldn't be certified for ifr.
Personally I think the pc12 should be restricted to the same wx as vfr on top. The wx on route also being a concern. Just my 2 cents

ipilot54 · Post by **ipilot54** » Fri Mar 20, 2009 9:59 am

I still like having the second engine so I do not HAVE to keep a sick engine running. I guess there is no such thing as a “precautionary shutdown” in a PC-12. As I mentioned previously, I have done two with turbine engines. Since I shut it down as a precaution vs. waiting for it to eat itself into tiny pieces, the cost was somewhat cheaper for the repair; fixing an oil line instead of heading to the overhaul shop. Gearboxes are not cheap last time I checked.

Of course, as you read the CADORs you see majors doing precautionary shutdowns as well from time to time.

And speaking of CADORs, here are two more involving PC-12s from today:

Where have I said the PC12 is unsafe jetflightinstructor?

As far as I recall I have only said I prefer multi engine airplanes for some phases of flight such as IFR over areas like the mountains and large bodies of water.

Can you paste where I said the PC12 is unsafe?

xsbank · Post by **xsbank** » Fri Mar 20, 2009 2:36 pm

I have had a PT6 bake on me, too, but I had 3 others all churning away earnestly.

I think the PC12 is a marvelous machine but it is a triumph of advertising and marketing over logic. Who buys these things? Not the pilots who fly them but the operators who are looking to save operating costs. Their primary concern is fiscal and whether the engines will cost them in airframe losses - they are willing to believe the manufacturers in exchange for that cost saving. Besides, they are not riding on them every day, if ever. PC12s won't be new forever - what about high-time airframe/engines? Still as reliable?

Yes, its a tremendous aircraft and everybody loves them and everyone who flies them can get into Air Canada. I still think that a single IFR aircraft is a giant step backwards.

How many of you would fly to London in a single engine jet? Jet engines are even more reliable than turbines - why not single engine airliners? Think of an aircraft with a single Trent in the tail - bet it would carry a great load, very economically, think how good the fuel economy would be? It could probably be the same size as an A320.

Not in a million years would I put my family on one, nor would I put them on a PC12 IFR.

Go ahead and fly them if you feel lucky, I don't happen to believe the hype. Wait until you've had a few engine failures like some of us have had, where the remaining one pulled me up and out of danger and took me to a nice long, safe airport and let me sleep in my own bed that night - 3 failures, 4 if you count one that I managed to get to the ground before it pooched; 1 turbine out of about 1/7th of my total flying, 3 piston-engines in the remaining.

Deal with it.

Brown Bear · Post by **Brown Bear** » Fri Mar 20, 2009 3:50 pm

This was not an engine failure.
If this engine had gone "bang" this thread would be a little different.
Is a PC 12 a safe airplane? Yes.
Would anybody depart at 100 feet and 1/2 a mile in a single engine aircraft equipped with a 1940's radial engine? I would hope not.
Are two engines better than one? Well, yes.
Are some engines better than others? Yes.
Would I shut down an engine in flight if I only had one engine? No. I'd make that puppy flail itself to death getting my ass to an airport.
Has Cat made any "untrue" statements? No.

Questions. Why, when anybody makes a comment so obviously intended to educate younger pilots, does it turn into a "bashing"?
Why, when anybody says something even a little negative about SEIFR, does "ORNGE" get mentioned?
Is a PC12 an aircraft to be "feared"? No.
Why do these subjects always turn into "I know more than you do.."?

Some day, some where, a PC12 will have a real life threatening situation, simply because there is only one engine. Will I be on board? Nope....but hey, that's MY decision. Not yours. Or Cat's.

Narrative: C-FMPA, a Pilatus PC-12, had just departed from Runway 15 at Yellowknife for Hay River with 7 people on board, when the pilot informed Tower that he had to return immediately. The controller suggested Runway 15 however the pilot advised he needed Runway 33, so ATC cleared the pilot to land on Runway 33. The pilot was able to land the a/c successfully and exit onto a taxiway, from which point the a/c was towed to the apron. It was later determined that at 800 feet AGL, the pilot observed a fluid from inside the cowling covering the windshield, followed by the failure of the PT-6A-67B engine. Initial information is that the number 14 fuel nozzle locking tab was never installed in the engine. The engine had run for 100 hours since installation. Representatives from Pratt & Whitney and Pilatus are en route to the site to examine the engine. It has also been reported that another northern operator has experienced problems with a similar PT-6 engine in another a/c type. OPI - Maintenance and Manufacturing UPDATE TSB reported that the engine failure of the Pratt & Whitney PT-6B resulted from one of the two fuel transfer tubes backing out. This allowed fuel to to be sprayed onto the engine and a less-than-required amount of fuel to supply the engine. This engine was received new from the factory about 100 hours before the incident. The fuel nozzle transfer tube locking plate (part number 3011158) on the number 14 nozzle was missing. The RCMP have submitted an SDR to Transport Canada.

Narrative: The aircraft was on an IFR flight from London International Airport to Ottawa (M-CIA). Shortly after departure, the aircraft returned with oil on the windscreen. ERS were called out and the aircraft landed safely. Ops. impact -- unknown. S.O.B. -- unknown. Supplemental information from Ottawa TCC (Airworthiness Inspector) -- [2000/05/30]: The aircraft had some maintenance performed before this flight. The angle-of-attack sensors were being checked (which required loosening the lines on the torque pressure transmitter). A post maintenance leak check was performed and no leaks were found. The pilot reported some oil on the windscreen and returned to the departure point. The lines were re-torqued and it is believed that this action solved the leak. Supplemental information from T.S.B. Initial Notification (#A00O0098): C-FMPB, a Pilatus PC-12/45 (serial #283) aircraft , departed London for Ottawa on a training flight. While climbing through 6,000 feet, a small amount of fluid was observed streaking up the windscreen. As the aircraft climbed through 8,000 and 9,000 feet, the amount of fluid increased to a point where it covered both windscreens and began to obscure visibility. The crew contacted ATC and requested a return to London. The aircraft landed without further incident. ERS was on standby for the landing. An investigation by maintenance revealed that the line 577.11.12.105B at the torque limiter connection was loose. This system had recently been disturbed for a routine 100 hour stall warning inspection. Tightening the nut and subsequent ground runs and test flight showed no further leaks. The RCMP are initiating a more thorough post-inspection ground run into their maintenance procedures. Two (2) S.O.B. -- both crew.

Narrative: The aircraft was departing on an IFR flight from Thunder Bay Airport to Sioux Lookout Airport. The aircraft had been airborne for about five (5) minutes when the flight crew noted a power loss and requested a return to Thunder Bay Airport. The aircraft landed uneventfully and taxied to the main apron. The flight crew then broadcast a Mayday message and stated that the aircraft's engine was on fire. Tower staff did not observe any smoke or flame and had not received any prior indication of trouble. ERS responded and stood down at 1503Z. Six (6) S.O.B. -- two (2) crew; four (4) passengers. O.P.I.: PAH Supplemental information from T.S.B. Initial Notification (#A00C0170): Wasaya 501, a Pilatus PC-12/45, was climbing through 9,000 feet after departure from Thunder Bay en-route to Sioux Lookout, when the engine (PT6A-67B) became unresponsive to power lever application and power reduced to idle. The crew regained engine power control by use of the fuel control manual override and diverted the flight back to Thunder Bay. After landing, as the aircraft was taxiing, the crew noted flames at the engine exhaust. They secured the engine, declared an emergency and evacuated the aircraft. No injuries were sustained and no aircraft damage was noted. The AMO suspects an internal defect in the fuel control unit and advised that during ground operations with the manual override, excessive fuel is occasionally scheduled, resulting in exhaust flaring. Further follow-up is planned with the engine and component manufacturer.

Narrative: Update #1: The registration was added. It should be noted that it was engine variations and not engine vibrations. During the return flight, the crew of C-FYUT noticed variations in the power turbine (Np) rpm and torque and, after a few checks, decided to land at Chibougamau/Chapais (CYMT). The pilot contacted the company’s aircraft maintenance engineer (AME), who confirmed with Pratt & Whitney the hypothesis that there was a problem with the constant speed unit (CSU). Two AMEs went to Chibougamau, replaced the CSU, conducted some ground tests, and returned on board the aircraft. During the return flight, the pilots and AMEs noticed a very small variation in the Np rate of revolution. The following day, the original CSU was re-installed and engine rigging was carried out. Some ground and in-flight checks were conducted and the problem did not reoccur. The aircraft was returned to service. It is possible that a slight distortion of the BETA valve caused this problem. *************** * *************** Mise à jour #1: Ajout de l'immatriculation. À noter qu'il s'agissait de variations de moteur et non de vibrations de moteur. Lors du vol de retour, l'équipage de C-FYUT a remarqué une variation du nombre de tours de la turbine de puissance (Np) ainsi que du couple (torque) et a décidé, après quelques vérifications, d'atterrir à Chibougamau/Chapais (CYMT). Le pilote a communiqué avec le technicien d'entretien de la compagnie et ce dernier a confirmé avec la compagnie Pratt & Whitney, l'hypothèse d'un problème de régulateur de vitesse constante (CSU). Deux techniciens se sont rendus à Chibougamau, ont remplacé le régulateur de vitesse, effectué des vérifications au sol et sont revenus à bord de l'appareil. Lors du vol de retour, les pilotes et techniciens ont noté une très légère variation du nombre de tours (Np). Le lendemain, le régulateur de vitesse constante original a été réinstallé et des ajustements de moteur (rigging) ont été effectués. Des vérifications au sol et en vol ont été effectués et le problème ne s'est pas reproduit. L'appareil a été remis en service. Il est possible qu'un léger désajustement de la valve BETA ait causé cette situation.

Spent a bit of time putting all that together....but...your point??

Why not do the same for a C172 or a King Air or any other type? You'd find the same stuff. If this stuff scares anyone...stop flying. Want to be really scared? Drive your car down the 401 for the same number of hours you've spent flying, if you can...
