NTSB just put the preliminary report up this morning. It's been 17 days since the accident. I'd say the investigators are still at a loss also.

Either their glideslope receiver/indicator-head was malfunctioning, their nav receiver tuned to the wrong frequency, or the pilot wasn't watching it for some reason.

The only comment of interest in that report was the implication that they weren't centered on the localizer until the last minute. In zero wind conditions, it's hard to see how that could happen.

Jetdrvr, can't you fly an ILS approach on autopilot in one of these things? And if "yes", is it common to do so?
