Fukushima Prefecture AW139 crash land, no immediatefatalities

Koriyama, Fukushima Pref., Feb. 1 (Jiji Press)--A police helicopter crashed in Koriyama, Fukushima Prefecture, northeastern Japan, Saturday morning, leaving two people on board seriously injured, police and fire officials said.

Five police officers, a doctor and a nurse were aboard the prefectural police helicopter Azuma at the time of the crash. The doctor in his 30s was among the two injured. All seven people remain conscious, the officials said.

The helicopter crashed into a rice field while transporting a heart for transplant, the officials said.

The crash came shortly after the helicopter departed from a hospital in the Fukushima city of Aizuwakamatsu at around 8 a.m. (11 p.m. Friday GMT), bound for Fukushima Airport, the officials said.

There have been no reports of injury to residents near the crash site.

and that's exactly why those forward seats need to be installed so you can climb up them to get out the cabin when it's side over. Hopefully nothing T/R related.

Shimatta! Maybe a wire-strike from too busy looking inside trying to match some certification profile?

Wow, that instant diagnosis of the cause shows a real insight!

Certification profiles only apply for certified (surveyed) sites. (Which wont have wires strung across them in the climb-out path). Wires can take anybody by surprise, and to suggest that the pilots were not looking out is unfair ( to say the least)

Sadly the heart went over its use-by date.

Why 5 police men on a transplant transport?
Was the heart of a criminal?

Pretty sure the "police men" were in fact the crew of the helicopter.

Well, if you look at the quoted departure point, destination, and location of the accident, it's unlikely to have been doing any certification profiles! More likely to be carrying out a precautionary landing en-route (which may have resulted in a wire strike)

a very valid point and if you're correct, it was only a matter of time for the 139. If they departed from ground level and used maybe a clear area or short field profile with eyes inside here, then this could have been the outcome. The cues can be a major distraction and their use requires proficient ADM.

Well, I think we can discount wires - like I said it would have been en-route.

I'm thinking Sky Shuttle here. Hopefully not another Italian Friday blade. I'm seeing 3 stripe blades on this image, unsure if crash airframe.

;Might I be the first to say this.....damn good flying!

Plainly some sort of Tail Rotor issue.

For everyone to walk-on/crawl away is worthy of praise

was this right after coming out of a seemingly CatA Helipad departure profile?
not sure why people keep referring to it taking off. Look up the towns/cities in the first post on google maps. It appears to have been en-route.

better shot of T/R here. 3 stripes and possibly no drive on impact. Agree with SAS, brilliant outcome with no flames or deaths.

I make it at about 10 minutes after takeoff, zero airspeed, slow yaw right. Some heroics to get it on the ground with as little damage as they did from that point. How to get into that situation from cruise? Did they lose yaw thrust (and why), lowered the collective but never got the throttles off and didn’t keep or regain their 80 knots? Gear was down, how did they get time for that as it surely would have been up for cruise.

Have I got the planned routing about right? The yellow circle being the final resting place. Destination was the airport.

A good outcome considering what might have happened. Dig a hole. Bury it. Buy another one.

My hunch, given the slow rotation rate, the throttles were at idle or off on the way down.

Heroics? Dang....you mean there was a School within two hundred miles of the crash site....that they gallantly sacrificed themselves to avoid?
