UPDATE: August 15, 2014, 11:34 local (15:34UTC)
In a matter of just a few more days, it will be three months since the unfortunate incident where Pratt & Whitney personnel blew up engine #1 of CSeries FTV1. The mishap occurred on May 29, 2014, and since then, the only one time engines where started again on a CSeries, was on test aircraft FTV4, at Mirabel, and it was for just a few minutes.
May 29 was also the last day a CSeries bird did fly. On that day, FTV4 took off twice from Montreal-Mirabel airport YMX/CYMX, thus logging its third and fourth flights. Altogether, CSeries FTVs (FTV1 to FTV4) have accumulated over one hundred successful flights, since the day where CSeries FTV1 C-FBCS did its maiden flight from Montreal-Mirabel airport, --11 months ago already--, on September 16, 2013. What a great day it was for aviation history!
As I indicated last week, Mirabel Bombardier Flight Test Centre (BFTC) did start up the engines on CSeries FTV2 on August 8. Last time FTV2 (C-GWYD) flew was on May 7, 2014. Let's hope this time, the BP2380 oil level was where it was supposed to be after the engine test. Link here: http://www.fliegerfaust.com/cseries-ftv2-working-on-statin-663606593.html
CSeries engines are regularly running at Pratt & Whitney Mirabel, Quebec plant as well as in the USA.
The change done to the Pratt & Whitney Purepower PW1500 series engines already delivered to Bombardier involved the Air/Oil exchange system, which is the internal secondary air for rotor cooling and oil system for the bearings. According to sources, this modification is an "interim" correction to allow CSeries to quickly return in flight toward giving the presently stalled flight test certification program a much needed impetus. Bombardier and Pratt & Whitney are confident to fly CSeries "in the coming weeks" :-)
All that having being said, what does it really means? From "what I understand" Pratt & Whitney seems to have resolved the issue. Transport Canada would have approved the solution. So far it seems. Now would be "solution implementation" time… What it would mean? Producing new parts, dissembling and reassembling all engines with the modification & modified parts.
Also, CSeries would need to return in flight in the coming weeks because a major order could be depending on when CSeries is resuming flights. Is this major order related to Qantas for QantasLink? Or is it related to the Flightglobal news released a month ago about a potential order of 50+ (or 20 + 30?) CSeries aircraft by Macquarie Airfinance (for Qantas?) and posted on my web site?

Since the engine test of last Friday, FTV2 had its engines removed. Is it related to what I wrote on July 26 please Pratt & Whitney, repeat after me "I will never do any more test to a CSeries engine while it's attached to a wing!") ?

FTV2 shoud host Purepower Pratt & Whitney PW1500 production version engines #10 and #11, same ones it was equipped with since its first flight. Engine P110 (10) and P111 (11) are currently receiving the modifications allowing for a returng in flight. We should expect an update from Bombardier on this whole issue soon or "in a few weeks" maybe.
About FTV1… seems like the damage caused by the May 29 incident has yet to be repaired. Depending on FTV1's status in the coming weeks, FTV3 located in Wichita should be the last one to return in the air. More to come soon about FTV5, first CSeries dressed up in a full interior livery, and FTV7, the first CSeries CS300, a longer version. FTV1 to FTV5 are CS100.
On May 29, 2014, FTV4 flew twice. No CSeries flew ever since.After FTV2 returns to flight, expect it to be heading pretty soon after to Wichita, where FTV3 is presently based.
CSeries flight recapitulation: FTV1 completed 66 flights, FTV2 27, FTV3 about 20 and FTV4 4 flights.
Can you believe not flying for 3 months is doing nothing to the test program schedule?
