"Honeywell don't seem to have grasped the offshore environment and have been badly caught out.
There were rumours they would be kicked off the AW139 in favour of Rockwell Collins."
I think Eurocopter already has with the EC175.

AW139 Engineer
Has anybody heard any more information about the Macau incident? did it throw a TR blade. Just wondering as I have removed from service some blades with lserious longitudinal cracks, not the hairline ones found in the scalloped back side root area of the tail rotor blade. The only places that can repair /refinish / statically balance and certify the Tail Rotor blades are Agusta (Italy ) and Rotor Blade Inc in the middle east. No one in north America .

AgustaWestland, a Finmeccanica company, is pleased to announce that the General Security Department of Libya has taken delivery of its second AW139 medium twin engine helicopter. The aircraft is part of a total order for five AW139s sold in Libya to perform a range of roles also including border patrol and Search and Rescue and was delivered by the all new LIATEC’s (Libyan Italian Advanced Technology Company) facility at Abou Aisha airport. The start of deliveries for the General Security’s AW139s sets a major milestone in the cooperation of AgustaWestland with Libya through one of the most successful models in its large and complete product range.

AW139 maintenance
Hello. Thought there shall be enough engineers working on these now to talk specifically about servicings? How about parts supplies? Any tricks to know? What about the 300 hour checks? How is everyone finding them? How long is they taking? Thanking you.

Hello
I was offered to make a research and analysis for AW139 avionic systems reliability as my thesis due to the reason that some operators have weird avionic problems with this certain chopter. For example blinking displays, windshield heater malfunctioning, sx16 searchlight malfunction, some kind of problems with MAU and NIC, external power CB popping out, weird CAS messages during flight etc. I have helped to fix some of problems and many more on a few AW139's (except the "problems" that Agusta claims not to be a problem at all
).
I would appreciate if you could tell what kind of problems have you came across associated avionics (both in the air or on the ground). If here is anybody who is an avionic then I would like to know if it's common for this specific chopter that wiring diagrams don't match with the aircraft.
If anybody knows somebody who I could directly discuss this subject with (in maintenance field) I would be greatful. Somehow I couldn't find anybody's contacts in the web who works in maintenance although I have found at least a hundred operators.
So far I have managed to gather detailed history for only a few AW139's but I hope get some more information about them.
Thank you and have safe flight.

Our aircraft has a squelch break when using FREQ. 127.85. It hasn't happened on any other freq.
Also the co-pilot MFD/PFD black out on takeoff intermittently, I suspect it has something to do with WOW.
There is also a problem with an ILS offset to the right which Agusta and Honeywell are both aware of and have a fix for but have not issued yet.

We had the same problem, and with help from Agusta Tech Support (Philly) I was able to "fix it" by reseating Relay K19, which is in the Cockpit Overhead Circuit Breaker panel. Maybe when mx is in there to comply with BT139-171 they can remove/op check and reinstall K19, reasonably easy to get too!! Have not had a problem since doing this. We thought it was a WOW switch also but had no CAS messages to associate it with any/all systems controlled by WOW
Wiring Diagram is at
AWDP - VOL 2 - 39-A-24-91-00-00A-051A-A Overhead panel installation - Wiring diagram
Hope this helps

Dunlop tyre loadings
With over a thousand posts it's bit hard to find if tyre loadings have been discussed.
I know a couple operators who operate with these Tyres and are getting poor mileage and uneven wear.
We have Dunlops with main wheel load ratings of 4000 lbs printed on them.
Nose wheels with 2150 lbs printed.
The Dunlop aviation tyre website for the 139 also says 140 psi recommended, and I know the maintenance manual mentions 210 psi.
4000
4000
2150
2150
12300 total rating on tyres, 139 weighs either 14,110lbs or 14,900 MAUW.
Am I missing something here??? Some one else must have noticed!!
Are people operating with overloaded and overinflated tyres?
Has anybody any solutions or point me to previous post.
Mick.

Mick,
Dunlop tyre design drawing shows the loads and pressures used in the 139 are outside the normal limits, but inside the emergency limits. Since you can only buy the tyres from Agusta and not even from Dunlop, I would say that Dunlop are ok with what Agusta is using them for.
Not sure if I have the drawing still or not. I asked Dunlop for it nearly 6 years ago when I first noticed the loads written on the tyres.

We had problems with MFD/PFD blackout and the change of relay helped but we didn't had the information of the location of the relay so we end up in a wrong place where was also a relay K19. If I can remember correctly it was in the ceiling at the end of the cabin. We had to find out ourselves that it was in cockpit overhead panel. One of the chopter's MFD still changes its brightness (very qiuckly from max to min and back again). It has happened on the ground and during a flight but then it works correctly for weeks.
One chopter has had one main tire changed so generally we don't have problems with these and we have main tire pressure 210psi
According to log books we haven't had problems with ILS at all but there's still a chance I missed it so I have to look again these.
Squelch break sounds intresting for me. I'll try to find out at some time if our chopters occurs that problem. So far I have heard nothing about it.
