Angel Flight Down

Here in Iowa City. One person -- the child being transported for medical
care -- perished. Read more he http://tinyurl.com/6dxct8

It's too soon to say for sure, but it appears the pilot attempted to depart
into stormy weather, apparently with a gusty tail wind. It rained extremely
hard here right before we heard the sirens, and the AWOS history indicates a
dramatic wind shift.

A TBM-850 is a very capable turboprop aircraft, and it was being flown by a
very experienced Angel Flight (like, 57 flights) pilot. Using the
aircraft's POH and the AWOS history, another pilot has determined that the
TBM would've needed something like 4200 feet to get airborne, given the
tailwind. Unfortunately, Rwy 30 is only 3900 feet long.

Be careful out there, guys and gals.

Well that is ridiculously sad.

Don't forget the basics you learned from your instructor: "take off
INTO the wind"

Writing generally, and not about this particular accidents, there are many
instances where that is not the best course of action, and it is safer to
takeoff with a tail wind than a head wind. Of course, you need to do the
math, but you should be doing that, to some extent, before any operation.

Was that takeoff distance calculated from MTOW and air transport
safety margins? Would the plane be near MTOW with those PAX?

No, it was using the mid weight TOW chart found in the POH, adjusted for
density altitude, rounded the wind down to a steady 20kts and totally
disregarding the 41mph gusts. It would not be beyond reason to believe that
the pilot may have attempted to rotate early, climbed into ground effect,
encountered a gust, and stalled.

If he would have used the 70% of take off speed within 50% of the runway
length rule of thumb, he would have pulled the power adjacent to the
windsock that was out his co-pilot window and pointed nearly in his
direction of travel, he drove right past it.

Jay Honeck laid this down on his screen :

Do you think he didn't know this or felt he could T/O regardless?

The article reports that the crash was "shortly before 10:08
a.m." (CDT). Wind at that time was 10023G36. If the pilot took off
from runway 30 with that kind of tailwind, it's no wonder he crashed.

The reported address of the crash site is just off the departure end
of runway 30 (map: http://tinyurl.com/6coeyb). But nothing in the
article says the departure was from runway 30. Perhaps the pilot took
off from runway 12, had partial engine failure, and tried to circle
back to land. (There are survivors, including the pilot, so we'll
probably find out.)

I will bet five bucks the pilot will claim he remembers nothing of the
whole event..
