Blown tire after 80 before V1 on short runway!

[Iflewjetz]

Falcon, good post. I can back you up.
I have had two blown tires. One on landing and one just taxiing to the runway ( in Dulles). They were both in airplanes with single wheel gear. A Jetstream in Greenville, Mississippi and an Excel in Dulles.
I will re-iterate what Falcon said.......YOU WILL NOT HAVE DIRECTIONAL CONTROL-----DO NOT CONTINUE!!

When I flew the Jetstream into Greenville, I just landed (didnt get on the brakes) and the aircraft "went for the grass" Luckily I was able to stop it and direct the brake a little to keep the turn less severe. We stopped on the runway and I went out to look. we made our own "grooved" runway. We asked if the passengers wanted to wait with us for the tug or have ops bring a truck out for them. We only had about 9 or 10 people. They elected for the truck. It was funny as he!! watching them load up into the back bed of a pickup and go to the terminal.

The second time it happend about last Spring. I was taxiing to runway 30? from Signature and like they always do, they sent us down through the airline ramp on I think A or C. They were doing alot of construction around there so I bet we picked up a nail or something I was taxiing probably about 10 to 20 kts and it started veering slightly right. I commented to my FO that I must have a brake starting to hang up. I slowed a little and then WHAM! it went right just like that and the airplane about stopped in its tracks. This happend at slow speed. Just think like Falcon said if it happens at high speed. ABORT!!! I got out, (after KIAD operations and security came to the scene) to take a look (as the fire trucks came). I could see a black trail where I assume it started going low and then a big black explosion spot about 10 or 15 feet behind the aircraft.

We had signature come to get it on a dolly. That didnt work so a mechanic came out and used a spare tire he had for NetJets and put it on ours just for the tow back. We were probably out there for an Hour and a half.
In conclusion, my point is on single wheel, you wont have directional control. On dual, you might but as Falcon said, it made the other one blow as well. Just be safe and abort.

Like one said: It is better to be at the hearing in a wheelchair than 6 feet under.

Yall be carefull out there ya hear.

Excellent post NYG

Thanks again to all who posted! Informative threads like this keep me coming back. Now if we could just get rid of all the BS!

BE400 and to all the others who are tired of the BS ...

There is another site out there that is run by professional pilots as opposed to webmasters selling advertizing. I cannot mention it by name because in this world I might get banned.

I suggest you check it out.

Another vote for stop. I've been through 3 flats, none were catastrophic tire failures, but they all resulted in an a/c that was:

A. Very difficult to control directionally
B. Vibrating so badly I was afraid of the airplane being damaged.

Granted, two of these were on landing and one while taxiing, but I can honestly say that in all three cases it was immediately apparant to me that I would NOT have continued a takeoff with that kind of problem. In other words, we can talk about it a lot, but I bet in most cases, if it happened to you, you wouldn't even hesitate to abort. The noise, vibration, and loss of directional control would convince you quickly of what to do!

I am convinced. Abort.

This was a very good thread.

Blown two (seperate occasions) on landing in a Falcon 20. Couldn't tell until turning off the runway.

Question for you Falcon, did you pull the chute??

Nope... This was a retro 20-5 with the Garrett apu mod that puts the apu exaust out of the tail cone. Like the Falcon 200. As a matter of fact now that I think about it.. I think all the retro 20s I was in had the shoot removed.

I can't say anything about aircraft with single tire applications, so there's my disclaimer, I suppose.

Otherwise, my sticking points are this: A momentary shove away from the centerline or even a nasty lurch that is recovered from is not a loss of directional control. "Very difficult" to control is not a qualifying high-speed reject item to me(in a jet).

I notice that most of the "abort" side of the conversation with experience, if memory serves, have all contended that they were on runways of considerable length; 10-11k feet. Usually if I'm launching on a runway of that size I'll mention it in a brief that will allow for sort of relaxing the high-speed reject items.

It concerns me a little to see so many of us making blanket statements that pretty much fly right in the face of almost all of our training. The major pitfall here being that we aren't always operating on runways with such liberal dimensions and to get in the mindset of sort of making up our own rules(not to be overdramatic) will one day lead to a wrinkled up airplane. I said it earlier, too, but I think it bears repeating......these reject items become almost exponentially more important as airframe weight increases.

I think it was mentioned earlier: it's the ground that's causing all that vibration and all those other problems......get away from it and give yourself a little time to think. In review: --SERIOUSLY consider your runway length(and know BFL). --Consider every takeoff as unique; just because you've seen it before doesn't make the same reaction jermaine every time. --Remember that this list of reject items finds its roots in statistics, high speed rejects are statistically ugly in the end. And how ever you react stick with your decision: if you're alive it worked, but maybe just that once, so keep an open mind.

I sum up my opinion with this: I think of flying jets as a blend of art and science. The art keeps people comfortable, the science keeps people safe. Science doesn't allow much for gut reactions.

Very nicely stated.

Not much you can do when the nose slams back down on the runway.

Sorry for bringing this thread up so late. As a FSDO once told me on another subject, but related to this topic. Good luck telling a NTSB judge that you decided to take it airborne when you briefed loss of directional control on your aborted items.
Another point, you will most likely blow your other main when you return to land.

Disclaimer: I'm an airline guy and have almost no experience in a single main wheel light jet.

At the airlines I've worked for the magic number for a highspeed RTO is 100 kts not 80, but the premise is the same. After 100 kts we're going unless there is a catastrophic control failure. The problem is what is catastrophic? I can tell you for certain if I did an RTO after 100 for a blown tire I'd have some explaining to do. We brief to the contrary so I had better have a compelling reason for stopping. Veering away from centerline would probably not be a sufficient reason unless I had a complete loss of directional control. Difficult control is still control. As bad as the situation may have felt immediately after the blown tire it's usually best to get airborne, evaluate and then find a runway and airport that is best suited for me to get back safely.

I'm not second guessing the above guys that have had to live this scenario. They made it work and are still able to talk about it. However, statistically they are in the minority. How many dead guys that aborted would do it the same way again? We brief for a reason. If we're going to ignore the plan, why bother?

My other concern is that even if the landing is ugly and you still leave the runway I'd rather have the crash crew staged and ready to roll than having to wait for the tower to call them. They could be with you in seconds rather than minutes.

Congrats to the guys that made it work and thanks for sharing your experience with us. It is extremely valuable information.

my .02 cents................ Whatever you do .......go / no go make sure you are both on the same sheet of music............. accelaration is not stopping and chewing up runway is not put on hold while this is discussed........... make the decision, brief the decision and for pete's sake stay with the decision
