Seems to be a bad month for aviation

Last year's August was pretty dreadful as well :-/

Just realised it's September. Sad start to a new month

Another Tu-154  :(

Grrrrrrrr! Im not! It just a shame that another Tu-154 has crashed  :(

Grrrrrrrr! Im not!

I was only kidding...

I was only kidding...

I know! but Grrrrrrrr.....  ;D

I noticed in school and confirmed in my cell phone, too sad!!!! :-/ and they say it's not because it's a bad aircraft but because they don't give appropiate manteniance..... , they can't play with people lives like that....

I guess I was wrong...

Don't jump to conclusions. Even the BBC report points out that it might not be due to technical failure.

According to Paul Duffy, Russian editor of Air Transport World, few Tu-154 accidents appear to have involved technical failure.

Mmm I just read this in "The Scotsman" from the crash in Ukraine...

He said the 16-year-old plane had flown 5,600 miles since its last maintenance check-up.

Thats why I said that, maybe I'm wrong....

At (roughly) 500mph, thats only about 11hrs flying - or about a day and a bit of flying, if say it can do three of four 2hr trips in a day - very little in flying terms. It probably has a check every 50 or 100hrs or so.

Define appropriate maintenance please. During a turn around, that can be no more than a walk around by the pilot and an oil quantity check. By a night stop, that will include a walk around, oil and hyd check, lights check in the cockpit and a cabin inspection for safety equipment. An airliner will fly for about 300 hours before it receives an "A" check. This inspection is nothing more than a safety equipment check; grease the gear and a walk around. That would be an "A1" check. Next comes an "A2" check after another couple of hundred hours. Same as the first, but a few more things, filters pulled and checked. A few hundred hours later comes an "A3" check and then an "A4". That check would include all the elements of the previous check plus for example hyd filters replacement, generator oil and filter replacement. At no time is any deep visual inspections carried out. "A" checks are "GVI", general visual inspection. In other words stand back and look. Does it look right, are all the bits their. "DVI" detailed visual inspection is for the doors, gear and the difference is, you use a torch/flashlight. Structural inspections are carried out every 4000 to 6000 flight hour depending on aircraft type.

90% of the time that a major problem is found on ANY aircraft type is down to two things. Firstly that manufacturer has noticed a problem during assembly/testing, or it was the lucky day on the part of the company that owns/operates the aircraft. Something else failed that has no consequence or connection to the major fault and the only reason it was found, was because something else was removed or inspected, and the major fault was found. Don't ever for an instant thing that it is different with the airline that you fly with. It is not. At the end of the day, AOG means money. Read the small print on the back of your ticket. Industry legal standard, you and you belongings are only worth $25000 compensation.

On the low amount of hours: EP-MCF just had a major check tupolev style (that means that they almost completely disassemble the plane) and a new paintjob...

And looking at the history, the problem is probably on the side of Iran Air Tours, and not on the side of Tupolev (or Airlines 400 who owned the plane before)...

How long before they blame it on the U.S.?
