Helicopter landing hard on the runway

jimnms says...

YouTube description:

According to the pilot-in-command (PIC), he was performing autorotations at the lower part of the main rotor rpm green arc in part due to weight considerations. Upon entering the accident autorotation, he maintained an airspeed between 85-90 knots in the hope that extra speed would allow a more aggressive deceleration flare prior to touchdown, which should in turn further slow the rate of descent and forward speed. The helicopter's rate of descent was high, and as the PIC turned the helicopter onto the runway heading it was apparent to him that the rate of descent was excessive and that he was too low to execute either a proper deceleration flare or perform a power recovery. He attempted to level the helicopter as much as possible prior to impact to minimize the damage to the helicopter and prevent injury. The helicopter landed hard with the left skid contacting the runway first. The left skid collapsed, damaging the outboard landing gear damper attachment structure. The helicopter slid about 100 yards before coming to a stop. According to the manufacturer, the main rotor rpm range is 90 percent to 106.4 percent. At the helicopter's weight and the density altitude on the day of the accident, the main rotor rpm during the autorotation should have been above the 106.4 percent limit (red line), requiring the pilot to increase collective pitch to maintain the rotor rpm within limits. Performing autorotations at the lower part of the green arc provides less availability of rotor energy to perform an autorotation landing. The pilot should have recognized that he was not achieving the required main rotor rpm for the autorotations and terminated the maneuvers. The helicopter was within weight and balance limits.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

The pilot's failure to maintain adequate main rotor rpm during an autorotation, which resulted in a hard landing.

They probably got suspended for that, they just don't bother reporting everything for obvious reasons, L.A.'s stigmatic history of her police force notwithstanding.

The illusion that these things happen everyday is only exacerbated by national and local, nightly newscasts. They want you to be afraid, so you will agree to their solutions to the "problem."

Gun culture or no gun culture, the chaos we're seeing is symptomatic of civilization-on-the-skids, in general.

If we had no guns, neurotics and burn-outs, the developmentally-disabled, off-the-charts hind-brainers, and morally and ethically bankrupt peeps would do it with clubs and knives and pointy, fucking sticks.

Wait until China fully rears her socially-inept neurotics upon the world as they suddenly become a power-player in the world economy-You think this shit is crazy??! Try a quarter of the world still 10 centuries behind a good portion of the world's population socio-culturally suddenly everywhere and anywhere. A wise man would teach his children some Mandarin phrases YESTERDAY!

I would ref at UCI all the time, yeah it does literally hit closer to home when these things happen.

My concern also rests with the police and how they seem to be trigger-happily handling this situation. Opening fire on random people is completely stupid and I don't see how they aren't pulled off the streets immediately.

What the Inside of a Dishwasher Looks Like While it's On

Winter is here, and here is your soundtrack to it.

I'm also from upstate NY and I thought I should point out that you forgot the most important winter driving trick: Learn to drive in the snow.

My father taught me to pretend there's an egg on the pedals when driving in the snow. Applying gas or break needs to be gradual and smooth. Any sudden change means loss of traction. The ditches are filled with people who thought AWD made them invincible.

Adding weight hurts as much as it helps. It may make it easier to get out of your driveway but it's not your friend in a skid.

My final tip is that snow is manageable if you are patient and drive smart but ice is always a gamble. In either case, no matter how safe you drive, you're at the mercy of the idiots you share the road with.

I live in upstate NY. We get tuns of ice and snow most winters. I normally drive a Subaru, but I keep an oldish jeep specifically for winter. Moral of the story: If you live in the north.. either buy a car just for winter or a good all-year car and avoid Minis, Fiats, what have you! At the very least put like 6 bags of salt in your trunk for extra weight.

It's almost as bad as people in states that get a lot of ice but little snow in the winter. Drive down an interstate and see someone every three miles fly into the ditch because they were driving 90 miles an hour in sleet.

This is how Hot it is in Iraq

Land Ahoy! And we are NOT stopping!

My favorite part is when she pulls the front brakes off with her bare hands...seriously?

All these kids in my neighborhood roll around skid stopping... so annoying.

heh, i guess i chose poorly for my first video submit.
i thought the skid was playing on the fact that some people think blacks would blindly vote for Obama because he's black.
if anyone seriously thought blacks vote blindly for Obama, and didn't like it, i doubt they'd find it funny.


I've informed Allah and the prophets of your transgressions.
You will hear from them shortly!!!





don't worry about it =)

What would it take to not vote for Obama?
