5 clarify that Fail Safe D is not 6 hours before
source | link

This last downlink transmission, ending ~24 hours before the flyby is a contingency plan. If New Horizons has a catastrophic collision as it passes through the Pluto system, we'll at least have some data. This downlink is called "Fail Safe D".

NH Closest approach: July 14, 2015 11:49:57 UTC

From Emily Lakdawalla's list, all times are Earth time (i.e. the time signals are received here, 4.5 hours after they were sent):

  • Monday, July 13 at 16:24 UT / 12:24 ET / 09:24 ET: 3.5hr downlink: Fail Safe D

  • Tuesday, July 14 at 03:15 UT / Monday, July 13 at 23:15 ET / 20:15 PT: 0.9hr downlink: E-Health 1

  • Flyby occurs at 13:49:57 UT

  • Wednesday, July 15 at 01:09 UT / Tuesday, July 14 at 21:09 ET / 18:09 PT: 0.3hr downlink: Phone home. No science data, just a brief burst of telemetry confirming that the spacecraft survived the flyby.

Your "6 hours before closest approach" would be July 14 around 10:20 which doesn't line up with any of the downlinks in this schedule, so somebody's off. I haven't found an original NASA downlink schedule yet.
