    1. We came across the crash site May 8 very close to 2:00pm. It was just 150 yards off of highway 51. The CompAir was upside down and in bad shape, the entire cockpit forward was missing. We were going to go have a look but decided to continue on our trip to Boise the see our mothers on Mother's Day. I'm glad we didn't go look, it would not have been good, I think we would have been the first people on scene. The crash site is just 8 mile's from the airstrip at Grasmere. When I passed back by the site on Monday there were feds everywhere and a plane flying around. I went back to Boise on Thursday and EVERYTHING was gone. I walked to the crash site and I smelled the fuel before finding the impact marks in the dirt. The plane had been cleaned up leaving only small pieces here and there. Very sad event!

    2. Wait, so you saw a crash site with no one there, including emergency vehicles and left to go on about your business?

    4. First of all folks, we had no way of knowing there was anybody in the plane, let alone how fresh it really was. There were no access points to get to the crash and the weather was super shitty and muddy. We live out here and the elements are brutal. It had rained and snowed for a few days up to that point so considering how we were packed and ready to go for mother's Day events AND very late, we opted to keep going on our way. Hindsight's 20/20 and believe me, my husband kicked himself for not going and doing something, but the last thing we needed was to see the Carnage that was obviously in there. I do love though how critical some folks can be when they have no idea what was going on at the time for us, not knowing how long that plane had been there or if it had already been taken care of in regards to attempted rescue. No need to be rude, presumptuous, or disrespectful to us or the folks who were lost. Whether we called it in right then and there or it was the next day, it wouldn't have saved the poor souls inside.

    5. But you have no idea. Your actions could have possibly have saved my wife’s cousin and his wife or at the least got people there sooner.

      I understand your hesitation for not going to find the rest of the plane but a phone call at least would have been nice so they weren’t out there alone until they were found Monday.

    6. "...but the last thing we needed was to see the Carnage that was obviously in there." True, the important thing is that the Mother's Day visit was not impacted by the effort put forth to hop a fence and slog thru the mud in an attempt to render aid to a fellow human.

    7. Thinking that a wreck hadn't just happened is an unfortunate but unsurprising perception when you don't see a crash happen or smoke rising. Unless no other vehicles passed by on highway 51 all afternoon, that perception must have been the same for anyone else who noticed the wreckage if no phone call reports were made that day.

      Offering criticism of not trekking in for a look isn't valid unless the commenter saw first hand what the weather, terrain, surface circumstances and wreck visualization was at the time.

    8. The plane went down at 2:09. How it did not look like it just happened is beyond me. I was not there, but you were obviously the first on scene. Life might have been saved with a little more effort.

    9. So sad that you could be so self absorbed to pass a crash site without ascertaining if the victims may have still been alive. Many people, like you and your husband, are cowards. Sleep well, zombie type person.

    10. "There were no access points to get to the crash," but "I went back to Boise on Thursday and... I walked to the crash site."

    11. Also, "I'm glad we didn't go look, it would not have been good, I think we would have been the first people on scene." Are you glad you didn't go look and be first on the scene or are you "kicking yourself for not going and doing something?" I guess I'm being a bit harsh because I knew the couple and considered them friends, but saying things like "I do love though how critical some folks can be" just shows zero remorse.

    12. I AGREE WITH THE CRITICAL COMMENTS. AT LEAST A CALL TO THE SHERIFF FOR GODS' SAKE.

  2. Why is there no info on this?

    1. I knew the couple, they were enroute to Boise from Reno. He was fairly low time in the aircraft. Awaiting investigation.

    2. The whole area is a range complex; general aviation aircraft transit it every day. The restricted airspace is for a bombing range.

      The sad thing is they flew over 3-4 ranch strips that aren't on the charts. From someone who was on frequency while this was going down, they reported a massive fuel leak and engine failure.

    3. ANOTHER STALL ON FINAL TO EMERGENCY LANDING ? DAMMM !

    4. No, that’s not what happened.

  4. "They molded a fiberglass header tank behind the firewall for separating air from the fuel into the engine. It split apart one day while taxiing. My feet were standing in Jet-A." https://www.pilotsofamerica.com/community/threads/comp-air-8-down-outside-of-boise-id.137944/#post-3250900

    1. Note: The quoted text is about a Comp Air 7 tail dragger.

    2. The Comp Air 7's tested in Iraq were tricycle gear and were models from a few years prior fabrication of the Comp Air 8 accident aircraft. Having sheet metal screws run directly into fiberglass instead of being equipped with threaded boss or nut plate fixings is not a witness to good design. Unfilled holes in the firewall and no grommet or firestop usage was noted also.

      Interesting reading in a file linked in the POA forum post:

  6. In ATC recording from above, the pilot states destination is KONO (Ontario, Oregon), not Boise, ID.

  7. M&M were flying to help my team and I install windsocks at LRAA in Mazama wa. We only found out today about this tragedy. All week we've been trying to reach them. Deeply saddened.
