Sunday evening, 17 December, a small plane crashed two miles south of
the Bucyrus Ohio airport (17G). A family of four (father, mother, two
children) died in the crash. There was minor damage to an apartment
building from flying debris, and no injuries to those on the ground.
The husband and wife are reported to have been pilot rated and
preliminary reports describe the aircraft as a 60's/70's Comanche.
Witnesses on the ground reported the engine sputtering and seeing sparks
coming from the airplane prior to the crash.
The aircraft had departed Oklahoma earlier in the afternoon.

Q: what are the possible ranges of various models of Comanche's?

My speculation...
Oklahoma to Bucyrus Ohio is a long haul. If the engine is sputtering, I
am guessing fuel exhaustion.
That it was within two miles of the airport makes me strongly think they
were stretching it.
Tulsa OK to Bucyrus OH is 665 nm. Fuel burn on a Comanche 260 is what?
14 per hour?
Cruise speed is 160 kts?
That gives about five hours and 700 nm.
How close am I?


Who knows? No one here knows any more about it than anyone else. We do not
even know if they stopped to refuel along the way. You don't know when the
oil was last changed, what kind of weather briefing he got, when the last
annual was, the condition of the electrical system, or anything else. So it
seems to be going out on a limb to be immediately suspecting fuel exhaustion.

Pilots in general have a pretty good idea of how far they can fly on a full
tank and they do not intentionally stretch it. Most of the guys who get in
trouble with fuel exhaustion seem to be people who encounter unexpected
headwinds, had to divert to another airport for some reason, or who did not
find fuel where they expected it.

So, I would not assume fuel exhaustion right off the bat. In fact, from the
facts given, I would not assume anything.

One thing I do know -- these people had family and friends, some of whom
might read these news groups.
