52 overhaul schedules plus IRAN

  

 I know nothing about CJ6 maintenance,but  suspect that, in military use, it is pretty similar to Yak-52.

  

 For the Yak-52 in Soviet use, every aircraft  was returned to a major overhaul facility at 500 hours, with an  extension to 600 hours where appropriate, and totally overhauled.  

  

 This means it was stripped down to the last  night and bolt and then rebuilt as a new aircraft.  This is not IRAN, but a  total rebuild!  

  

 Obviously the State was paying and so no  cost consideration; the aircraft were being flown very hard, but the fact  remains that is the level of maintenance that was expected.  

  

 Obviously more gentle western use should be  reflected in less onerous maintenance, but that is what the manufacturer  intended.  In the UK, we  have persuaded Yakovlev and the UK CAA that  the 600 hour overhaul can be replaced with a detailed inspection, but even this  involves wings and tail removal; engine out; x-rays / magnaflax etc. every 600  hours  

  

 If there is a problem through lack of  maintenance, I suspect that an excuse that the maintenance was not locally  compulsory would not be accepted!

That is similar to the Chinese schedule.

That is different. The Chinese IRAN, not overhaul. But then they throw

the airplane away at 3000 hours.

That does seem a bit stiff.

I don't think it would be here either. The FAA would probably slap you

with the "careless and reckless" clause because you ignored accepted

maintenance procedures and it caused an incident or accident.



BTW, did Sean Carroll ever pay you the money he owes you? I still

haven't gotten anything out of him.

Richard, 

  

 I was  aware of the 500 hour rebuild in Russia and what was accomplished during them,  from talking at length with Vladimir Yastremski and Sergei Boriak.   

  

 What I  was not aware of was your mention of xrays and magnafluxing.   

  

 Do you  have details on those inspections that the Russians were doing (regarding Non  Destructive Inspections [NDI]), or are these inspections something that you have  come up with locally?  

  

 Thanks  for the information.

It's in the SU-29 manuals.  Magnaflux and some kinda ultra sound test for the composite wings - hasn't applied until this year for me  - the rear wing spar attachment thing.  But, "it's in there"

  

 If you want the Sukhoi -word for word - contact me off list I'll copy it for you.

I appreciate the offer Rick, but it would  seem to me that the requirements would differ between the YAK-50 and the SU-29  by quite a margin given their massive difference in design.  Still....  metal is metal..... so yes, I would be interested in hearing what exactly they  are looking for cracks in.  

  

 I don't keep up much with Sukes... but does  this rear spar deal also apply to the 26's and 31's and if so, how often?   I have friends here with both aircraft and I do not see them making any special  inspections... and I'd know.  Perhaps they are overlooking something  important?  If you know of a mandatory rear spar inspection using  magnaflux on the SU-26's or 31's PLEASE let me know  ASAP!

I understand.  I was just putting in my 1 cents worth that the Russians do think about that techno stuff.

  

 The cracking problem was identified in Nik Timofeev's SU-29 and applies only to the -29.  He found his port side rear spar attach fitting broken and the starboard cracked.  So, I think this is a one time thing.  The Russians, from what I've gathered from their communications on it think its an anomaly and are treating it as such.  The Friendly Aviation Agency is pushing as hard as it legitimately can to issue this as an AD.  My notification was on "FAA AD letterhead" so to speak - you know -the same format.  So...according the FAA it is mandatory for we SU-29 drivers only.  

  

 I started my Annual Conditional Inspection a few days ago and mine are fine - both sides.  I think Nik's is a unique case but it doesn't take much at all to check while you have the sides off the airplane off for inspection anyway.

  

 Yak-50 huh?  A great relative to have.  I never flew one but Azat (my Ukraine bud - National Champion) loves the darned things he flew/flys them for the "Yakovlevs" UK Akro formation group when he's not flying Capt. on B-737 for Ukraine International Airlines (yea Azat).
