Blackhawk Emergency Landing


I’m not sure if this one is new or not? I’d certainly like to know what’s going on and if that was the only place it could be put down.

Halfway through Ray Leoni's book "Black Hawk - The Story of a World Class Helicopter" - now that is the helicopter I want to crash in - if you see what I mean! Incredible design effort from the outset. Design initiatives and processes still not surpassed by 'modern' contenders.

Do Airbus expect 175 and wastelands a 189 to compete with this? Both tarted up oil and gas cabs. Sikorsky must be salivating.

I don't think it makes contact with the light stands - i think it's the downwash that takes them out.

More likely catching a wire between them.

I think you could be right about that on looking at the video again.

A friend in Bucharest posted this on FB: Driving in Bucharest can be a nightmare sometimes but coming across this landing on the roundabout. Seen it all now.

What? Having an unexpected emergency when S&L requiring an immediate unsafe landing? Or the blade strike?

Well, technically the 189 is the civil variant of the 149 which was launched earlier

word on the street is that the crew reported a loss of Rotor RPM, noise/whine, and a chip light, entered autorotation, and during the auto, something "broke free" and single engine power was re-established. This allowed them to continue on one engine down to the traffic circle. During the deceleration, the aircraft caught a wire that was strung between the light poles and that brought the pole down. I'm purposely leaving more specific details out because everything I know is at least 3rd hand info. Based on what I heard, it sounds like the crew did a good job managing an abnormal situation and subsequent loss of NR.

Thanks for the update that helps make sense on the profile and initial approach to the traffic. It would be good to know mechanically what actually happened.

Greetings

Hello all, just joined up here. Read a lot of posts/threads on here over the years, mostly while trying to find information regarding incidents/accidents in the rotorcraft world like this one out of Romania that is being discussed now.

As you can tell from my user name this incident is of interest to me because I crew/maintain Blackhawks for work(nearly 12 years now). It will be interesting to find out the rest of the story on this one, thankfully there was no loss of life so those involved will be able to recount what happened. The aircraft’s IVHUMS system will have recorded everything as well, so lots of good data will come out.

My first impression watching the videos was what happened to cause the rapid decent? It was very aggressive, like an entry into an autorotation. Which fits into the loss of power/drooping NR scenario that has been mentioned.

I can only assume at this point that no systematic mechanical fault has been identified as no ASAM has been released by the Army for special inspection of components etc.

Second impression is that the crew did well to get it on the ground safely, although there were several points in the videos where it appears they were mere feet(inches?) from destruction.

The new crew coordination training for the Army and the new emergency procedures in the checklists stress “Fly the aircraft first”, gain or maintain safe rotor speed, attitude, altitude, speed and heading rather than immediately actions, though obviously for some emergencies there are still immediate actions that are required.

They are trying to cut down on incidents where crew have shutdown the wrong engine or misinterpreted/responded to the wrong emergency procedure and crashed a flyable aircraft.

The new procedures/checklist have only been out for a little over a year, will be interesting to see how that affected this incident as well. As a side note, the only emergency procedure in the new checklist that has AUTOROTATE as an immediate action step is dual engine failure. Only 6 are LAND AS SOON AS POSSIBLE.

Looking forward to the information/discussions on this forum!

Dan

Good post, Dan. Bucharest is roughly 300 ft msl and July temps max average 84F, so the empty except for crew 60 had single engine hover capability+, yet they chose to land on a major street with vehicles, ergo, something else was going on, one would surmise.

Enough can not be said for the crew wrestling that beast to the ground. Without a doubt, that was exemplar behavior. But seriously, what was that all about?

60,

The basic failing of Emergency Checklists is that sometimes the failure does not show up in the list even if it is correctly identified.

Anyone that immediately reaches for the ECL before ensuring they are flying the aircraft and have decided upon exactly what that means....including who is driving, where the destination is, and how they are going to get there....running down items on a checklist is not that hurried a task.

The new Army concept makes far more sense than what was known as the "Dipped Shoulder Method" where one of the Pilots upon seeing a Master Caution Light immediately reached for the ECL which easily led to mistakes as crews hurried through the procedures.
