- The fatal crash of Hughes 369 helicopter being used to trim trees has a backstory that gives insight into what went wrong. This workhorse of a helicopter apparently had damage from previous incidents.
The NTSB investigation found cracks in an engine mount that were likely present before the crash. John Goglia and Todd Curtis look beyond the fatal accident and share three previous investigations involving this helicopter. Two involved a crash with serious structural damage or a hard landing. These events may have stressed the engine mounts.
The fatal crash happened when the helicopter was in use for an operation that used a large 10-bladed saw to trim trees close to power lines. The helicopter went into a spin and low altitude and crashed, killing the pilot.
This episode highlights the importance of knowing an aircraft's history. Studying previous events involving a particular aircraft could reveal issues that should be inspected more closely or more frequently. The required 100-hour and 300-hour inspections were completed for the helicopter at the center of this discussion. However, additional inspections would have been smart given the previous accident history of the helicopter.

It is a 5 place, not a 2 place.
10,000 parts flying in formation….. what could go wrong ?
And yet, people crash their fixed-wing aircraft Every. Single. Day.
What do you mean two seats ?
"What about Gyroplanes."...I flew one, and I'm hooked.
It’s a four or five place gentlemen 👨✈️
Doesn’t sound like these guys know too much about helicopters…..
Doesn’t sound like they know anything.
More like nothing
Yep, it’s embarrassing
When are you planning to talk about Bill Anders last flight? Inquirirng minds want to know.
Like that one : I’m fearless but not that fearless ! Yes sir - well said .
Good catch on the previous accidents. There may have been appropriate maintenance, or not. It would be interesting to compare the maintenance requirements vs the recorded maintenance actions for each accident. BTW, those engine mounts looked poorly maintained (although youtube resolution makes it hard to tell for sure). The paint should be smooth and continuous allowing for easy identification of damage, cracks and corrosion just as it for fixed wing engine mounts. I have both fixed wing and helicopter commercial pilot ratings although the majority of my experience is in maintenance. Thanks for the video, every effort makes a difference.
Guess you've never spent time with a Hughes.
@@user-jq2rf4nf3o I learned to fly in one.
You lost me at “too place hella cawptuh.” And “wook hoss.” Have you guys ever actually seen a chainsaw? Because that machine is nothing like a chainsaw.
Am I watching an episode of All In The Family?
It's obvious you guys haven't a clue on the facts of the Hughes 369 - A drain in the fuel system has a service letter on is issue of sucking air killing the engine. More parts are removed on condition and time life on a helicopter then any fixed wing.
A static mast isolates the rotor system - Main gearbox has one input and can be removed by itself, Tail rotor driven by gear box , One damper block, Been flying & fixing helicopters for 45+ years Hughes, Bell, Hiller, Sikorsky, Robinson, etc.
Drones are not the solution. And those cracks shown are NOT the cause of this accident the remaining 'spuds' are still in alignment and not out of place. That operation is placing the helicopter in the middle of the H/V diagram over trees.
You're better off doing long line work over a flat building top, (I did that kind of work too) At no time you stated how much fuel the helicopter had on board... At low fuel loads you can draw air while maneuvering (Like in sawing)
The freewheel clutch also has a few ADs and service letters on it all by itself
Stick to fixed wings
Crazy how something so important can be completely concealed by paint. Yet, mandating teardown and stripping the paint would be impractical without a good specific reason to suspect a problem, and never something the best pilot preflight will catch. What were the specific steps that should have been followed for the hard landing inspection? Would even they have caught this?
Those cracks in the paint are nothing, The "spuds" are not displaced or deformed. NDT at overhaul or condition
Too bad there aren’t any verbs which mean “raise eyebrows”.
Well, there’s “surprise”. But if you substituted a two-syllable verb every time, the video would be too short.
What Army unit uses these for observation? Special Forces use MD’s for insertion and gun ships. How much do you guys actually know? Can’t understand why you guys don’t do your homework before making videos.
Get it done ! I don’t want to hear your complaining - Get it done or I’ll get somebody else to work here . We pay you guys good money so shut up and get your job done ! ✅ I don’t want to hear it ! 😮
Never in 45+ years of Commercial Helicopter work have I heard such a thing...
Were the proper engine mount inspections done ? Obviously - NO ! Ooo No !
This company ain’t looking good - Junky copter - Equals - crash for absolute certainty . Wow !
Those mounts had no issues, paint yes, no issues mechanically Spuds not deformed or displaced, no bends or other deformation in the tubes. Engine weight 145 lbs if it's a 250C20 series.
Hughes / MD Helicopters have a service letter and a few ADs on the freewheel clutch...
IMO that helicopter should have been retired many hours before the last crash happened. You have to know that there is going to be deep seated metal fatigue throughout the entire structure of a heavily used vehicle. Either bad inspections or inspections that did not go deep enough. It should have just been timed out.
I disagree. I've seen, and flown numerous aircraft, both fixed wing and rotor, that have far more time than that one did. It's not about aircraft age, it's all about maintenance.
@@slopsec2358 As long as that maintenance means tearing down the vehicle to it's component parts for a deep examination of each part or replacement schedule we can agree. All materials age, decompose, fracture etc over time. You have to be willing to a full and complete tear down to replace aged out parts.
@@kmg501 Sometimes yes, and there are other ways as well. Ever heard of magnaflux?
I've flown helicopters older then I. A continued airworthiness schedule is maintenance and retirement of time life parts. All FAA approved set up by the manufacture. Inspection times. Overhauls, Repairs ,Replacement of parts that exceed limits on condition or timed life... As Jerry Dees of the FAA says "It's all good"
Stick to fixed wing gentlemen, you’re embarrassing yourselves on this topic.
