  1. My company I work for utility we had a line cut lucky for the pilot his wire cutter worked didn't crash. We only found out because we asked the property owner what happened he told us about the crop duster.

    1. was the PIC identified for ur $ costly repair costs?

    2. No, but I was thinking that bloggers who make useless remarks be fined $25 for each occurrence. The excuse of being old and cranky is not a defense.

    3. What's useless about GB asking if the plane that cut the wire was identified?

      Possible answers include:
      - No, we didn't find out.
      - The spray company contacted us and we worked it out.
      - Our utility line maintenance handles auto accident, treefalls and similar damage to lines as normal activity. No charge to car, truck or aircraft for these type of repairs.

      (KR provides a lot of useful insight. Hope my curiosity about how line damage is handled doesn't earn me the "cranky" citation, too.)

  2. WAY back in '78 my PP instructor told me Crop Dusting has a high crash rate... I've seen so many now on Kathryn's report I'm starting to think he was correct.......I still fly but LOW and SLOW.

    1. ^^And when you peel the onion back on them all and compare them, most tend to have the same root cause: pilots didn't see power lines or other obstacles. Any flying activity that has a higher risk of low level aggressive flying like Ag flying is going to have a higher number of crashes. It's just the nature of the beast. There is more margin in GA flying up much higher and wings level for errors.

  3. This pilot was injured but prayerfully will recover. A lot of these AG plane crashes end up as a fatal crash. I consider him very fortunate. I think it should require a lot of planning flying these AG aircraft. I would think with navigational aids available today that these types of crashes should be less common!

    1. Marker spheres on lines adjacent to where aerial application is conducted are the best aid, but the vast number of placements that would be required to make a difference for Ag pilots is staggering.
