SpaceX Classified Zuma Launch Delayed Until At Least December
http://aviationweek.com/awinspace/spacex-classified-zuma-launch-delayed-until-least-december
That's really unfortunate for both the costumer's Nov 30 deadline and SpaceX's FH fit checks...
When's the annual maintenance scheduled for?

Can anyone with subscription access to AvLeak please let us know if the behind-the-paywall article discusses exactly what was found wrong with the F9 fairings, if the fairings have been flying with this weakness for years, or what?
-Doug  (With my shield, not yet upon it)

Ok, haven't read the article but found out that the range maintenance period goes from today to Dec 1st. If true then it's possible Aviation Week doesn't actually know anything about the fairings but is just reporting the obvious delay based on the stand down period.

So they'll likely work on 39A for FH during this downtime, right?

Well, based on what we know and have reported, there really isn't a lot of work that could be done until Zuma is away. 

They still have to cut into the TEL, remove the east-west hold down clamps (which are 100% needed for Falcon 9 single stick missions), they have to install the compression bridges (which, again, can't be installed until Zuma is away as the compression bridge can't be installed until the east-west hold down clamps are removed)...

Basically, not really.

Basically, not really.

So all they can do now is work on the RSS and play the Jeopardy theme until the range is back online?

And even if they resolved the fairing issue by then, how close to CRS-4 could they launch from 39A?

RSS work, FSS work for crew Dragon mission... those can certainly continue.  As can other pad work.  I'm not saying all FH work stops until Zuma is away; I'm saying that the schedule-driving work is dependent on Zuma's launch as that work can't begin until Zuma is away.

Assume you mean CRS-13.

Depending on launch time alignment, the two missions could go - as far as the Eastern Range is concern - no closer than 16hrs from each other.

Worth a post in the update thread.

James Dean at Florida Today reports that Range maintenance down periods have been interrupted before to accommodate launch needs. 

So a hard close of the Range until 1 Dec appears, from a historical perspective, to be negotiable.

As a very authoritative source reported, they did some monkeying with range maintenance schedules for Intelsat 35e this July, so it wouldn't even be a first time for SpaceX in the last six months.

Oh thanks, that's much closer than I thought

(Yeah sorry had Iridium-4 in mind  ;D)

Why does it take so long to switch missions on the Range?

That’s less than half what it used to take (2 days IIRC).

Also interesting the conjecture that Zuma could have been a launch readiness drill:
Quote
Some have gone as far as to suggest that there really is no Zuma mission — that the pre-launch preparations were an exercise to prove SpaceX's ability to fly on short notice.

SpaceX put a Falcon 9 on the pad at KSC and test-fired its main engines on Nov. 11. The rocket went vertical again before last week's planned launch attempts, but has since returned to its hangar.

Under that scenario, the payload fairing tests SpaceX cited might merely be an excuse to stand down from a launch that was never really going to happen.

Well, it would give some context to the name Zuma as a homophone (sort of) of Zoom indicating speediness.   But really, that seems a bit of a stretch and highly unlikely.

Not to mention that they would've to put forward another 'excuse' if this mission is never going to happen, as the fairing issue alone wouldn't do it, and as a commercial company I don't think they would release potentially damaging false statements.

Why does it take so long to switch missions on the Range?

What takes time is the physical relocation of range hardware - e.g., tracking cameras - that is deployed for a launch to a specific launch site, that needs to be moved to the other launch site. Any buildings that need to be opened on the other launch site, and any electrical switches, computers, and so on, have to get opened, turned on, and confirmed to be operating correctly. Also, the people working on the range need to be reset - food, rest, etc.

As cppetrie mentioned, this is much less time than had been required before. The range has been significantly modernized in the past several years and a great deal of effort has been put forward to making operations more efficient and lean.

Can't they install the missing South side hold downs?

I'd guess NG is pushing for Nov 30 to meet some contractual delivery date. This is probably what was meant when it was previously discussed the customer was intent on meeting some revenue milestone.
NG financial Quarter/Year end is December 31st...
Only thing that matters is the date on the contract between NG and their customer.

KSC opened up pad tours today it seems (multiple Instagram posts of the tour route). This would correlate to the payload being off-site (i.e the PPF @ CCAFS) as tours are prohibited if there is a fueled payload on-site at the launch complex.
