robottxt 50 Report post Posted February 8 Airbus sent a private letter to a few diligent operators years ago about this issue. Some operators accepted it, others did not and demanded an RFM update. The NP RFM has a similiar statement as above. With one minor difference. (*) Operation at OAT < -20°C is approved provided that MGB andTGB oil temperature at engine start is ≥ -20°C.A procedure to measure the oil temperatures is provided in the Aircraft Maintenance Manual (MET 60-00-00-603).

Zazu 68 Report post Posted February 9 Shoot! That’s right! A few years back, at a different company, I was issued a little infrared heat gun. And we used 254. Share this post Link to post Share on other sites

VERTICAL REF 7 Report post Posted Monday at 10:22 PM Unless you are running the Castrol Optigear 32 break in oil. For the duration of the break in period (100 or 200 hours I think?) , then you are limited to 0 degrees C, I believe. Check the MM. Share this post Link to post Share on other sites
VERTICAL REF 7 Report post Posted Monday at 10:37 PM And have also had this conversation with Aerospatiale. Leave Ft Nel or Ft Mac at -32 and after one refuel, land in Calgary or Lethbridge at plus 9. Share this post Link to post Share on other sites

Maufacturers are responsible and can be held responsible for what ever they provide and sign in writing. After you crash and the TSB finds out it was due to the wrong oil in the main or tail rotor gear box, your Insurance Company is going to be very unhappy and I beleive you will be also. File an emergency A.O.G. to TCCA and a copy to the Manufacturer. If you believe that you are going to get a consensus of opion on this site you are really dreaming, you are probably the first person to beleive this is a learning site, welcome. You should call AirBus in Fort Erie and ask to speak to the CEO and not the support staff. Put exactlly what you said originally in your post and a copy to your Insurance Company and explain to the CEO that you are in violation of ICAO and TCCA regulations for not adherring to the RFM. Advise the CEO that you will be seeking compensation for lost revenue. Don't forget page 8, Section 2.1, "Notes : - The temperature limitations mentioned above apply to engine starting."

VERTICAL REF 7 Report post Posted Monday at 11:20 PM I must have timed out and got kicked to the curb. Page 7, Section 2.1 bottom of chart (**) Operation.....oil temperature at engine start is equal to or greater than -20C. And they are probably missing those two asterisk for the synthetic oil 5 centistoke MIL 23699 as well. Share this post Link to post Share on other sites
