| Subject: | Re: Evans Coolant and SB-912-043-R2 |
While not available on this side of the pond (at least I have never seen it) this
coolant comes to the attention of the FAA in the most recent Bi-Weekly AD listing,
Incidentally this AD refers to The Stemme S10-VT Motor glider and not to Rotax
engines
Extract from FAA Bi-Weekly 2007-02
The mandatory continuing airworthiness information (MCAI) states that:
During certification works it was found that the cooling liquid EVANS NPG+ is flammable.
The liquid cooling circuit of the Stemme S10-VT is not designed to be
filled with a flammable liquid without prior modifications. For that reason,
this Emergency AD requires the replacement of the EVANS NPG+ cooling liquid.
In addition, the operation limit of the cylinder head temperature must be temporary
changed to 120C / 248F.
Actions and Compliance
(e) Prior to further flight as of January 29, 2007 (the effective date of this
AD), unless already done, do the following actions.
(1) Replace the EVANS NPG+ cooling liquid in accordance with the instructions of
Stemme F&D Service Bulletin A31-10-076 Am. Index: 01.a, dated October 9, 2006
