Ohio midair crash kills 3

[Larry Dighera]

There's still no information on the FAA web site:
http://www.faa.gov/data_statistics/accident_incident/preliminary_data/

Does anyone have any more information about this MAC:


http://robots.cnn.com/2007/US/05/11/aircraft.crash.ap/index.html
SHARONVILLE, Ohio (AP) -- Two small planes collided Friday
afternoon over suburban Cincinnati, Ohio, raining debris onto
roads and back yards and killing three people on board but missing
those on the ground as rush hour approached, federal investigators
said.

The two aircraft narrowly missed falling on a busy freeway.

"I'm just thankful it wasn't worse than it was, with school buses
and people coming home from work and the interstate that we have
nearby," said Michael Schappa, Sharonville's police chief.

The Federal Aviation Administration had no information about the
planes' flight plans or why they were so close together. Blue Ash
Airport, a runway used by small planes, is several miles away.
State Highway Patrol Lt. Wayne Price said investigators assume
both planes took off from there.

The planes' pilots were not required to file flight plans and
apparently were not in contact with air traffic controllers, the
FAA said. Under federal regulations, the pilots were responsible
for maintaining a safe distance on a clear, sunny afternoon.

NTSB: Planes clipped wings
BY JON NEWBERRY AND PEGGY O’FARRELL | ,

SHARONVILLE – A witness told federal investigators that she saw
two small aircraft clip wings before spiraling to the ground in a
collision that left three Greater Cincinnati men dead, an
investigator with the National Transportation Safety Board said
today.

Ed Malinowski told reporters that the planes were traveling in
opposite directions when they hit.

Killed were Niels Harpsoe, 64, of West Chester, pilot of a
Beechcraft Bonanza V35B that crashed on East Kemper Road west of
Reed Hartman Highway; as well as Edward L. Hitchens, 65, of Symmes
Township, and David Woeste Jr., 31, of Anderson Township, who were
in a Cessna Skyhawk that crashed at 5862 Squire Hill Court.

The Hamilton County Coroner’s office is conduct autopsies today on
the three victims.


• David Woeste was father of four

• Edward Hitchens was "mayor of the block"

• Friends remember Niels Harpsoe

Malinowski confirmed that the Cessna was carrying a flight
instructor and student and that the plane featured dual controls.

Hitchens was described as a veteran flight instructor. It is not
known which man was in control of the Cessna.

Federal investigators and the Ohio State Highway Patrol are
gathering clues on the crash.

Malinowski said it will be a few days before investigators can
look at radar reports from a nearby airport, if any such reports
are available.

Investigators want to know the direction and speed at which the
two planes were flying, he said.

Right now, Malinowski said, investigators are focusing on
gathering perishable evidence from the two crash sites.

I don't have direct information, but I do fly in and out of KISZ on a
regular basis.
- Without knowing what the winds were at the time...
the location is where one aircraft would be on right base for R24 and
where a departing aircraft would be on left upwind crosswind if
departing R06.
- some local speculation in a high-wing/low-wing situation where visual
separation lost or was not attained.
- no one has commented on hearing any communication from either aircraft
as yet.
Personal note:
- the name and address of one of the C172 occupants is consistent with a
former high school teacher I had 35 years ago.

That's a bit of an overstatement. The plane that crashed closest to the
airport landed less than three miles away from the approach end of
runway 24. The other plane came down about a mile north of that. They
were outside the traffic pattern, but well within the airport area.

I've heard (but have no direct knowledge or proof) that the 172 was an
instructor and instrument student doing instrument approaches and the
Bonanza had just departed. Regardless, it seems that the Bonanza was
either on a departure or an approach and the 172 was conducting training
operations involving landings.

Weather was clear, visibility probably around 10 miles. At this point
we mostly only have speculation.

I live not too far from the accident scene, and I have a scanner that
records all CTAF communications in the vicinity and uploads to my
website. I have not searched the audio archives carefully, but perhaps
one of you might want to take a look and find if anything relevant to
this crash shows up. Here is the link:

Yours may be the sole record of these transmissions. Thank you for
making them available.


From the FAA preliminary information (below):

pilots):

So it appears that the Bonanza was inbound from the north at 6,000'
(5,144' AGL) for left downwind entry to runway six, while the Cessna
had just departed runway six and was at 2,100' (1,244' AGL) at the
time of his last transmission. It would seem that both aircraft would
have had their view of the other obscured by their low/high wing
configurations. Tragic.

Is this correct, Larry? The pilot stated he was at 6,000 feet and only four
miles from the airport, which has a traffic pattern altitude of approximately
1,800 feet?

I found that datum troubling also. The Bonanza would have been
descending rather rapidly to arrive at the pattern entry point at
1,800'. Because the Bonanza reported he was north of the field and
would make a left down wind entry to runway six, he may have been in a
slight right bank at that point obscuring his view of the Cessna out
the side window.

The Cessna pilots transmission is more difficult for me to decipher,
but if he flew a left crosswind after departing runway six, he could
have also been in a bank to the right or left depending on whether he
was departing the pattern on the left 45 or remaining in the pattern.
If the later, his view

Listen to the recording, and see if you agree with what I heard:
http://www.sarangan.org/aviation/scan_audio/2007051115.mp3 Where I
included ellipsis (...) in the Broadcast column, it is meant to
indicate that some of the transmission was unintelligible to me.

[john smith]

Andrew, have you contacted the Cincinnati FSDO to let them know you have
this?

[Andrew Sarangan]

Thanks for the transcription of the audio file. I should also add that
my computer's clock was about 9 minutes 30 second behind the official
time, so all the time stamps must be advanced by approx 10 minutes to
be correct.

That may be true of the times shown on your web site, but the times
included in my transcription are offsets into the audio files that
have little correlation with time of day, as the receiver's squelch
eliminated all the dead air time.

How have you configured your receiver to record these files? I might
like to do something similar.

Listening to the preceeding/succeeding recordings, all other traffic at
Blue Ash was using R24.

I heard the following...

8:50... unintelligible for Blue Ash

10:15... Blue Ash traffic Bonanza 1835L is five miles north of the field
will be entering left downwind runway six full stop.

10:22...Blue Ash traffic Cessna 6614D has just departed runway six now
departing on a heading 360, climbing through two thousand one hundred
will be looking for the Bonanza on ?.

10:41... Blue Ash traffic Bonanza 35L four miles from the field at 3000
feet will be entering left downwind for runway six.

10:55... a mic is keyed and an unintelligeble, excited voice and audio
squeal can be heard. The transmission last one second.

11:14... Cherokee 3874W calls midfield for right downwind 24.

I don't know if I'd say that. According to your transcript, at
10:25 the Cessna reported departing runway 6, then it appears that was
corrected to runway 20. Maybe I'm reading it wrong? I can't really
tell which runway the Cessna departed from for sure.

John Galban=====>N4BQ (PA28-180)

[John Galban]

Belay that last post. I just realized that the airport in question
only has runways 6 and 24. Did the pilot of the Cessna know that?
Did he mean 24 when he said 20? He seemed to be trying to correct
something.

I also found that the clock on my computer was approx 9mins 30 seconds
behind the actual time. Also, the transmissions from the Blue Ash
traffic pattern would have been difficult to receive from my rooftop
antenna. I am about 20 NM to the north of Blue Ash and only 1.5NM
south of MGY airport, so any transmissions from MGY would have easily
overridden transmissions from Blue Ash.

It is not difficult to set this up if you have a linux system. It is
an ordinary scanner, and the audio is fed into the soundcard and
captured using the 'sox' software. Sox has switches for selecting the
input threshold (squech) and to do various processing to create
virtually any output format you like. If you are interested I can
send you the script file (really trivial - it is only one line long).

My setup is primarily limited by the fact that the antenna barely
clears the top of my roof but I still get pretty decent reception out
to 30 miles or so.

There is some unintelligible audio at 10:54 that sounds like it might
be the same voice as the Bonanza pilot. Then at 10:57 something that
sounds like "you guys too close".

There are also several free or very cheap Windows apps that do the same
thing. For years, I recorded scanner audio of the local PD / FD.

Will the software you mention not only create the audio files, but FTP
them to a server also?

The software resides on my server, so uploading is not an issue for
me.
If you doing it on windows, it may need extra setup. I will write up
something about the setup and post it to my website in the next few
days.

Probably not, you'd need to script that, or actually save them to the
server.

In my case, I create the mp3 files directly in the public_html
directory on the server, so there is no ftp or scripting involved.
Linux makes this all very easy. I don't know how one would do this on
Windows.

Set the application to save the mp3 file to the public directory? <G>

I don't think that's all that difficult to do in any operating system.

Can you schedule tasks on Windows like crontab, and set priorities
with nice? May be it is possible, but my linux machine runs unattended
for years without any trouble. My windows machine needs to be rebooted
every few days because it gets slower and slower the longer it stays
on, and something always crashes requiring a reboot.

Sorry!

The only reason I mentioned that you don't NEED Linux to record scanner
audio was simply to point out that it's _possible_ to do so with
Windows, for others who might want to try it.

I have lots of professional experience with lots of operating systems,
including SCO, SunOS, and System V Unix, along with Linux, and really
don't wish to play OS ****ing contests.

Thanks!

That file is only 10:13 duration, I've searched the ones before and
after... I downloaded it again to be sure, and still get a file that
ends before either of these planes make a call. The one after it,
nothing but mention of the aftermath. I've tried a bunch of them
now... where'd I take the wrong turn?

The file for 1400-1500 is 12mins 3 secs
The file for 1500-1600 is 10mins 13secs

So you might be looking at the wrong file.

I downloaded the trial version of Adobe Audition to see if I could clean
up the audio. Unfortunately, the trial version does not allow access to
any of the filters. Does anyone have any software that can perform this
function?

Have you tried Goldwave? It is a shareware. I used it before, and was
quite impressed with the functions. I do not recall if it had
functions to do filtering.

Give Audacity a try. It is free under the Open Source license and is a pretty
powerful audio file editing tool:

See 'man ntpd' and /etc/ntp.conf - very useful for keeping the
dreadfully inaccurate clock on a server in check.
