N702H, crash near KMTJ on mar 22 at about 2000 UTC
« on: March 23, 2014, 09:23:17 PM »
N702H, a TBM 700, crashed at about 2 pm mountain time / 8 pm GMT on the 22nd while on approach to KMTJ. According to the approach plate for KMTJ (coming from the south), it should have been on 125.35 with Denver Center, but can't find anything in the audio archives. Can anyone help try to locate audio for the flight?

Thanks.

Also they must have been on an IFR flight plan and in contact with ATC because N702H was in Class A airspace at 26000 ft in Denver center airspace. Looks like descent started around 1935z or 135 local mdt. Again, any assistance much appreciated. Thanks.

Curious too. He can be heard on a 1900-19:30 clip about 24 minutes into the clip asking for another frequency due to the other pilots transmissions being gargled. A reply is never heard. Please let me know if you find anything.

Maybe the coverage is just bad due to the mountainous terrain. But if anyone finds this, please post.

Has anyone found the ATC on N702H prior to the decent etc?

Please someone correct me if I'm wrong, but if he departed KBVO (Bartlesville, OK) at 12:12 PM CDT which is 16:12 ZULU time then wouldn't he had been on Denver 125.35 at 18:00+ ZULU time not 19:00-19:30 as the upper post states???? I'm being very honest which I say someone correct me if I'm wrong........ZULU is -6 CDT and -7 MDT

With the time change to daylight savings time, Zulu time is now only 4 hours ahead of Eastern Daylight Time, 5 hours ahead of CDT, 6 hours of MDT and 7 hours ahead of PDT.  The Zulu times mentioned in the above posts are correct.

You could do an FOIA request with the FAA. they'd be required to turn over the tapes.

Preliminary NTSB report is out. http://www.ntsb.gov/aviationquery/brief.aspx?ev_id=20140322X03239&key=1

Apparently pilot communicated to ATC that plane was in a spin. No further details. Best guess is pilot-error (i.e. failure to maintain proper airspeed and failure to apply proper spin recovery) and/or icing changing the stall characteristics of the airplane (and requiring a higher airspeed). Possibly also tail stall which can occur in icing conditions when flaps are deployed or airspeed is reduced (but tail stall speed is far higher than wing stall speed).

He was 19 miles out on approach, looking at the temperature and spread on the ground at the destination it's pretty safe to assume he was picking up a load of ice at altitude in light rain and clouds, was probably flying on autopilot and didn't notice the incremental changes in trim and handling, and by the time the AP couldn't manage it anymore and disengaged he was in command of an essentially unflyable machine. He also had four passengers and probably luggage, so W&B may have been a factor re spin recovery... plus the fact that nobody has been trained in actual spin recovery for the last few decades. Even back in the 80's I had to strap on a chute and take an aerobatics course in order to get mine.
