So Phrog,

What would you do for a Sync Shaft failure?

Yes, I think Frank Piasecki was a genius as well, a mad genius perhaps..

 

[bert]

There are some good lessons learned in that SIR. Well worth the read.

 

[bert]

The Canadians actually had a Synch Shaft failure EP. For Navy phrogs we didn't even bother.

 

[MasterBates]

Bert, something like this?

SYNC SHAFT FAILURE-
*1. Bend Over
*2. Kiss A$$ Goodbye

If A$$ is intact and not burning:

*3. Emergency Egress

Note:
Waiting until aircraft is on ground to egress may lead to step 4.

If A$$ is intact, and on fire:

*4. Screaming Alpha Procedure- Execute

I don't know how the pilots are going to reach up and secure them with all of the centrifugal force. I went to one of Mike Durant's (Blackhawk Down Super 64) speaking engagements and he stated they were pinned against the doors. I think he said they landed with one PCL 1/2 off and the other full up.

I had a skipper who had a loss of control over the deck, but for all intents and purposes, it was loss of drive, just not spinning quite as fast. He said they were able to get to the PCLs in time fine and set it in the water. I'm guessing their spin wasn't quite as dramatic as Durants, what w/ a lack of TGB and all.

Bert, you should see the 60B sims. Can you say archaic?

Archaic, yes, but still modeled Loss of control vs. Drive.

 

[bert]

Should have been that. They used to come down to HC-3 and one of us RAG tools (errr, instructors) would run them through their annual sims. The general nature of the procedure was to make no control inputs and wait for the universe's general benevolence to kick in.

So Phrog,

The procedure you detailed is one... I used to brief that if we had a sync shaft failure, that our emergency procedure would be to make peace with our maker, and quickly. Yes, I considered that a memory item.

Had a nugget ask me one time what one emergency I am most afraid of. I told him dual flight control boost failure, and he couldn't figure out why. I told him "think about it, you can't move the controls, and assuming that you had the aircraft trimmed up, you just fly until you run out of gas and then crash. You can't PEL, you can't autorotate, etc... Why do you think single flight control boost failure is land as soon as possible?"

 

[bert]

Towards the end, the utility hydraulic pump/flamethrower started to scare me. That and the fact that they once took pieces out of my xmsn filter that you could read part numbers off of...

 

[MasterBates]

The NSIU is what scared the fvck out of me. I had 2 fail, both at night. Once behind the boat on a DARK night.

NSIU failure can mean no flight instruments other than Pitot-Static. And it does not fail like NATOPS says it will either..

 

[bert]

That is a problem mostly gone with the R - though from your pic that isn't a worry for you anymore.

 

[MasterBates]

Nah, NSIU to too cutting edge for the COD.

call it being in the wrong place at the right time , but i've had the misfortune of watching two aircraft lose t/r thrust. One was a complete loss of the tail section after a mid air. think sudden stopage for you helo guys. The other was a component failure. I was in dash three in the mid air and saw the whole thing. It happened at about 300 ft with an external load. Very seasoned air craft commander flying with a guy 5 months out of flight school. The CW04 didn't have time to punch the load but got the aircraft onto a road and all 15 onboard survived. He said much luck and devine intervention was involved.
The other incident happened while the crew was coming in on an ILS and the drive shaft failed. I was at the airfield running and saw them break out at around 700 ft then started to spin. Crew performed an almost flawless auto . Aircraft rolled when it landed but crew walked away.
