Subject: F-22 AEF Deployment
Date: 12 Feb 07
Narrative:
1. A 1st Fighter Wing AEF 6-ship (Petro 91) departed Hickam AFB
enroute to AEF location on 10 Feb. Approximately 4 hours into the
mission and coincidental with crossing over the International Date
Line, all six aircraft experienced a significant avionics failure
including:
Both GINS 1 and 2 Fail
FLCS Degrade
Radar Fail
Fuel Degrade
Loss of all attitude references
Loss of Flight Path marker
Loss of all navigation aides (TACAN, ILS, Computed, etc.)
Loss of all heading indications
2. Aircraft communications were available via backup radio only.
Only navigation available was via cockpit airspeed and altitude
indications (both deemed accurate). All other aircraft systems, to
include engines, electrical system and air refueling, were nominal.
3. Flight Lead, initiated via the tanker a
CONFERENCE HOTEL (CH) call with LM Aero. All CH team recommended
workarounds (avionics restarts, date and time resets, etc.) did not
resolve the problem.
4. Flight Lead assessed pressing to the AEF location but decided
to turn back and return to Hickam. He also directed the second
deployment cell, a 2-ship approximately one hour behind him, to return
to Hickam. NOTE: This 2-ship never crossed the International Date
Line.
5. Enroute back to Hickam, after crossing back over the International
Date Line, avionics restarts were unsuccessfully attempted.
6. All aircraft successfully recovered at Hickam, shut down (cold
iron), restarted engines and all avionics malfunctions cleared.
