Thanks, I was looking at exactly those two pages. :-)

However, I noticed something interesting:

!SFO 07/048 SFO RWY 10L/28R CLSD WEF 1307062310
!SFO 07/047 SFO RWY 10R/28L CLSD WEF 1307062309
!SFO 07/046 SFO RWY 28L PAPI OTS WEF 1307062219

The PAPI was reported OTS and the Runways were closed at the same time. Isn't this a result of the crash? The time is a few hours after the crash.

The glide path on the 28L ILS was reported out of service earlier:

!SFO 06/005 SFO NAV ILS RWY 28L GP OTS WEF 1306011400-1308222359

So, my question is: was the PAPI really OTS earlier, or is this entry really as a result of the crash? Was there an earlier entry that has been superseded?

It looks like the threshold to Runway 28L had been relocated. If the PAPI’s and Glide Slope transmitter had not been moved to the new threshold that would account for them being out of service.

I first learned of these NOTAMS from NonValueAdded's comment #386.

"KTVU talking about the NOTAMS now ... out for about a month - normal visual glideslope equip is inoperable due to construction. Pilots expected to eyeball it in. PAPPI - bank of lights - was out."

Notice XHogPilot comment #406:

" The ILS for both RWY 28L and 28R have been inoperative for several days. It is likely the pilot was not aware.

!SFO 06/005 SFO NAV ILS RWY 28L GP OTS WEF 1306011400-1308222359

!SFO 06/004 SFO NAV ILS RWY 28R GP OTS WEF 1306011400-1308222359 "

So they were out effective from 2013 June 1 1400Z thru 2013 August 22 2359Z.

HOWEVER ... Notice

So ... NOTAMS

!SFO 07/048 SFO RWY 10L/28R CLSD WEF 1307062310
!SFO 07/047 SFO RWY 10R/28L CLSD WEF 1307062309
!SFO 07/046 SFO RWY 28L PAPI OTS WEF 1307062219

Went into effect from July 6 at 2320Z, 2309Z, and 2219Z time respectively.

In my opinion, the PAPI were really OTS earlier because they were turned off due to construction, to prevent "landing too short" with the 300 foot displaced threshold.

Then, the NOTAMS were reissued because of the crash and the fact that they were destroyed or damaged.
