Mad Jock: How eloquently put! ;)

VF - A very lucky escape given the unforgiving terrain; good job on getting her down without pax injuries. Hopefully, that will be your only 'brown trouser' moment...
Looks like the tail has become detached from the fuselage as well as the skids being left behind a wall. What was the total extent of the damage? I'm surprised it's flying again so quickly :confused: TTB |
that was close call, glad that you and all your pax are ok...
better be prepared, it can happen to anyone of us any day.:rolleyes: p.s. good to know you can actually squeeze them that far down in the Nr range, something that you don't test on daily basis.:O Came across your bird in Norway in May 2008, then it obviously had better day then the one in the field. assuming this is the only one with this trim http://farm8.staticflickr.com/7256/7...73eef230_b.jpg |
Glad everyone walked away from that one and with the convenience of not needing to step down from the aircraft!
First point - don't operate the engine like an Allison 250! |
First point - don't operate the engine like an Allison 250! I have seen so many operators doing just that. Prolonged idling - progression from the 250 and or 101 and doing 2 minute run downs. Habit. Not good due to low oil flow around the rear bearing and heat build up. This progresses to carbon buildup in the scavenge and vent. If the scavenge blocks it is possible for oil to migrate to the rear of the GG 2nd wheel. After that there is a good possibility of losing a turbine blade. 30 seconds is the required run down and then turn it off as any more is detrimental. There is a graph around somewhere that shows the temperature initially reduces in the area of the rear bearing then after 30 seconds it climbs again and does all sorts of strange things. If you have been idling run it up to flight again for a while then back to idle then shut down. Any maintenance in the rear bearing area requires plenty of attention to details and procedures. The bearing is after the 2nd wheel on the extreme right. http://www.gg-pilot.com/ggupload/Expo11.JPG ref the AD here is a picture of the buildup that comes off unevenly which causes the vibration and rear bearing failure. http://www.tc.gc.ca/media/images/ca-...tions/20_1.jpg |
Do you know if this 'heat climb' problem during shutdown is peculiar to the B2 engine, or does affect other Arriel motors as well?

Thanks for all the posts and great photos. Glad you made that last one safely.
By the way, i really hate my job now. Fly safe! FR8 |
Is this you VF? or your company? saw it on a news website, the story was "avalanche in Himalayas kills 10 climbers"

RR: If you check-out post #18 on this thread you'll see that the craft in question (9N-AJZ) was delivered to Simrik Air. She was at the Singapore Air Show in February prior to her delivery.

Truly epic pictures and what a :mad: of an auto-landing. Thumbs up for saving men and machine.

Thanks for the positive remarks on my Auto. Sheesh I had not too many options; I had to walk away, we all had to walk away, as we all had too much more living to do :ok::ok::ok:

Top of the World - Manaslu avalanche update
Namaste
Manaslu avalanche update On the 23rd September at around 4am a massive avalanche swept away camp 3 on Manaslu. To date there are 11 seriously injured all now received medical attention in KTM. 8 bodies have been recovered, I flew 6 missions to 21,529' at -3.3∘C to bring down 5 Blessed Bodies & flew 4 Sherpa Climbers up there to assist in the search. To date there are still 3 Mountaineers missing up on the Mountain, search efforts will continue today. OmOmOm 🚁🚁🚁🚁🚁🚁🚁🚁🚁🚁🚁🚁 |
Fly safe, VF

Good morning fellow Rotorheads
I have been too busy to post pix here, but I am posting pregularly on Face Book (too easy on the iPhone) so if You would like to catch the latest pix then please friend request me at : Steven Bruce Bokan Cheers & Happy Landings always :ok::ok::ok: VF :cool: |
VF
Well done on surviving that failure so well. I'm intrigued you took the rotor rpm so low below minima to range extend. Normally the factory flight manual limits are best, have you checked with AS if that was a good idea? I think your photos are great, I only flew offshore in India & didn't have those views! |
have you checked with AS if that was a good idea? I understand your point, however VF was in the hot seat and I guess he did what he needed to do to preserve life/s. well done Steven |

Good morning Nigel & Belly Tank
Re my Auto following engine failure....Well I can say this much; the sight picture on the normal Auto numbers was putting me straight into the Karnali river which at that time of year (monsoon) is a raging torrent that would have been unsurvivable.:mad: When I went to 100kts & bottom of the Nr green; the picture looked better but I was still going in the drink :{:{:{ then hmmmm (this may sound crazy to some people) I then broke all the rules; common sense, airmanship, experience, the RFM limitations..... I believe I was guided by the hand of God & just kept pulling up on the lever till I could see I was gonna make it. Vibration was severe. During the glide; common sense cut in for a moment & I lowered the lever wanting to get Nr back into the green but I lost the sight picture to my elected landing zone, :{ so, without thought or will, the lever went back to where God wanted it to be & was the ONLY position I believe where we were gonna make it......& we did. 5 x PAX all survived without a scratch:p & 1 x Pilot scarred for life :\ but still flying :ok::ok::ok::D:D:D Happy Landings ALWAYS :cool: VF |
There is no such thing a "cheating" in an auto when you have but one place to go.
Well done! |

Dear VF :8,
Always impressed with your work, both at the controls and with a camera. One quick question on the last photo of this tragic (a local cardiologist died in this avalanche) event; how high is the wall left from the break? With no visual references in the area, it's hard to get a sense of the height. Thanks & keep up the great work :ok: |

Thanks for your kind words :O The remaining wall left after the avalanche varied from nill to 300' high :mad: The adventure continues..........................................:ooh: Happy Landings..............always :ok: OmOmOm VF |

Hello and Good afternoon Vertical Freedom, from Sunny Lancashire,
Again a stunning few pictures of your everyday view from your mobile office window, Despite the rugged beauty of that almost untouched area you fly in, death still awaits at every chance to steal the hearts and minds of thoses who dare to reach out to what looks like one of the last unfriendly frontiers. Take care VF, many of us down near to Sea level read your posts. My regards Peter R-B Lancashire UK. |
What Peter said. Thanks, VF, you're doing a fabulous job chronicling one of the most fascinating areas on the planet. I dare say many of us live vicariously through your adventures. :ok:
Safe flying, CB |

Namaste Peter-RB & Carbon Bootprint
Thanks for Your comments. Yes here in Nepal is amazing & probably amongst the more challanging places to fly thanks to ultra high landing elevations, DA (ISA +30oC) & crap weather :confused: we have some of the highest accident rates here for both Fixed & Rotory Winged aircraft's due to the mentioned reasons :\ So the adventure continues :p OmOmOm VF |
