Default NTSB report - ILS and ATC. How does it all come together?

"The minimum altitude for the approach was 376 feet above the ground."

(Is that for a point 2.5 miles out? ...where the power line is 150 feet
AGL?)


It seems to refer to the straight-in LOC MDA (which is 396' above TDZE in
the current chart, but perhaps it used to be 20' lower).

(See where I'm going with this? I don't get it. Duh! 376-ft was the
"minimum
altitude for approach." So, what does that mean - where does 376-ft
start?)


The MDA applies inside the FAF, which is 4.6 nm out.

Heck, they might have hit the 150 foot high power lines 2 seconds into the
power outage?


Perhaps it was the plane's collision with the power lines that caused the
power outage.

(Overall, are my numbers right? How does someone on an ILS "end up" at 150
ft (AGL) 2.5 miles from the threshold?


The terrain could be higher further out (but I haven't checked whether
that's the case here).
