Mmmm...

Well as this seems to have happened in Doha ... I would suggest the operator is Gulf Helicopters !

S.No is probably only known to the engineers picking up the bits and Agusta


Hope this allows Agusta to sort this little snag out BEFORE somebody get hurt.

The operator is Gulf Helicopters, Apparently the a/c was taxiing out for takeoff and the tailboom fell off. From what I have been told it broke off aft of the #1 Rad Alt antenna. Machine is fairly new.

Pictures?

You telling me that there was absolutely no sign visible to maintenance or to the pilots conducting the pre-flight that a tailboom was about to fall off?

139 tail boom

The report I've seen says the aircraft suffered a 'tail boom strike' back in March. Following detailed manufacturer structural checks it was returned to service. Yes, Gulf Helicopters.

Airwave. I would never expect you to eat a dirty hat - you can wash it first.

Malabo. Having a camera airside in Doha is a flogging offence - as in most paranoid Arab countries.

For all most people know- it could have been an Airbus A340 flight AW139. It did not occur to me that we could have been talking about helicopters, about which I know little or nothing (along with most readers), and after all, isn't there a section for Rotorheads anyway?
This is the Rotorheads section, and in the helicopter industry everyone knows what an AW139 is.

Are you lost, or didn't wake up properly

Froggy, it started in the R&N forum and was moved here along with the comments from confused R&N readers.

As others have mentioned and I have it on good authority that this same machine was previously involved in a tail strike when taking off from a platform without the autopilot connected. So airwave45, next time you watch your supremely professional DOH crew just take note if they are actually using a checklist or not.

SAS,

Bell's do not loose tailbooms so why would you say this?

As to the alleged happening on the 139, you could say they lost tail rotor drive just like the Cougar S-92. In this case they did not kill anyone!!

Sultan,

You must be very new to the game.

Bell Helicopters had a very long learning curve with the Huey series.

Tail booms fell off those machines with disgusting regularity. We lost two aircraft in one day at Fort Rucker due to that killing six people.

The problem started at the four bolt attach point, and with modifications worked its way to the 90 degree gearbox attach points along the way. The Cobra was notorius for shedding gear boxes from the tail boom.

It was not without basis it was said Bell Helicopters killed more troops than did the NVA....althought not exactly true in actual numbers but enough to have some weight.

how its made

Quote:
glued together (or not?) in Poland ...
NOT, only bare airframe w/o tail assembly made in Swidink

Tailboom is attached with 6 attachment points to the mainframe. Very similar design than the B412.

3 pretty strong bolts on either side holding that together - makes me wonder how hard the previous reported "ground strike" was

Sultan, I find your reference to the S-92 accident highly offensive and totally irrelevant!

It's also clearly not an "alleged" incident - it actually happened!

PS. It's 'Bells' not "Bell's"

212man,

Sometimes one has to consider the source and simply ignore the comment!

Wish I could do that but as the Good Book says...."One should not provoke another Man."

AW139 Engineer

Usually structural failure of the AW139 tail boom is contributed by landing the helicopter on its tail just prior to the main wheels. Figure it out guys
I personally saw this happen in Vergiate a 3 years ago and it also happened in the UK DEC 23 2008 on a private machine (Report not yet released) The main root cause is poor training. Don't blame the helicopter, this same scenerio has happened on many other types also.
