Citation I Drag Chute?

Thu Apr 26, 2007 11:35 am

I have an operating manual for a Cessna Citation I/ISP and was suprised to see that a drag chute was optional for use during ground operations. Has anyone actually seen an example of an aircraft with this system installed?

There is a Falcon 20 on our field that is equipped with a drag chute. Not sure about the actuation of it or what the system is composed of.

Is it a cargo ver.? All the old Fedex Falcons had drag chutes.

It was actually standard (or a common option) on Falcon 20's, pax or cargo, at one time.

Some Learjet 35/36s have drag chutes. I learned about them from this accident report:

Quote:
On December 3, 2002, at 0612 Pacific standard time, a Gates Learjet 36A, N546PA, was destroyed after colliding with an elk, and subsequent runway overrun, at the Astoria Regional Airport, Astoria, Oregon. The airplane is registered to C F F Air, Incorporated, Wilmington, Delaware, and was being operated in support of a Canadian Armed Forces training exercise under the provisions of Title 14, CFR Part 91, when the accident occurred. The two pilots and two support personnel aboard the aircraft were not injured. The accident occurred approximately 1 hour and 30 minutes before sunrise under visual meteorological conditions. Impact forces and post crash fire destroyed the airplane.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge on December 3, the pilot-in-command (PIC) reported that during acceleration for takeoff (approximately V1 [takeoff decision speed]) the airplane collided with an elk (the left wing was the initial impact point). The PIC reported that after the collision, he applied wheel brakes and deployed the airplane's drag chute, however, the airplane continued off the departure end of the runway 08. The airplane came to rest in a marshy bog approximately 180 feet beyond the departure threshold.

You know - although it didn't end very well for the plane, (and probably ended badly for the elk as well) you have to agree that this would have been much worse had this happened at 30,000 feet.

I mean, after all, someone would have to explain what an elk was doing up that high in the first place.

The Falcon is a passenger aircraft. I do not know its full history, but as far as I know it has only flown people.

I knew there were, I've seen them and even taken off behind them before, but running a search just seemed like too much work for something I already knew.  Smile

Oh, I didn't mean to correct you....just helping show Tlfd what they look like. I think it's interesting that a jet designed for corporate luxury found such success as a freighter. I wonder if the designers ever foresaw such a mission requirement.

Running small high-value freight on a Falcon (or other Jet... I've seen old Lears in this use too, especially checkrunning) makes more sense than using the Cessna Caravan. The speeds at which the Caravan runs you almost wonder why they didn't just truck it. Especially some of those Fed Ex Feeder routes.

Back on topic... how does this chute work? Somewhat like a dragster? Why not just use a thrust reverser?

Yep, just like a dragster. Many of the jets that employed the system didn't have reversers. The Hawker -400 series comes to mind. Reversers notwithstanding, though, I think the idea was to provide a method of slowing above and beyond reversers, in the event of engine failure(s), for example. I'm sure some of the more seasoned folks around here can provide some more specific info and stories....

Thinking back to my (very limited) experience with dragsters, that's got to be a b**ch to repack... not to mention having to drag it back to the ramp after you've slowed and turned off. Interesting concept though. Would love to see one in action somewhere, but it seems as if they'd be a last-resort deal.

Yeah, it must be a pain. I wonder whether there's an explosive charge to release it...

I know some military jets can release the chute after they've slowed. Not sure if the same holds true for bizjets.

Thanks for the examples 2H4. I had no idea the 20 was used so extensively for cargo purposes. I know the pilots of the 20 on our field keep saying they need to test the chute and promise they'll let us ride along, but no luck so far.

Keep on them about that, and be sure to station a buddy by the runway to get some shots!

Fedex got their start in 1973 with Falcon 20s, as the US laws at that time made it difficult for them to use anything bigger. Wanting a bigger freighter, the determined that a freighter version of the Challenger would be legal and would have greater capacity. They got Canadair to create a freighter version of the Challenger and ordered a sizeable number. Before they took delivery of any, Fred Smith got the US Congress to change the laws in 1977, allowing him to operate bigger freighters. Fedex cancelled their Challenger orders and started buying 727s. When they sold their Falcons, many ended up with Flight Refueling in the UK. Here is one airframe, before and after:

Interesting stuff guys. Thanks.

A billionaire in my hometown here has a Falcon 20. It must be a bit of a rocket, as it has taken off from his resort's 3980' private runway (PA88) at an elevation of about 2000' which equates to a relatively high DA in the summer heat. Definitely made a nice bit of noise coming over our high school a few miles under his mountain ridge back in the day when I was there. Had no idea he had a parachute behind that thing... couldn't hurt though with the little strip he was landing that thing at up there. I'm meeting the pilot of it in a week here, I'll have to remember to ask him about the 'chute.

The Falcons were still flying when I got hired but I went to the 727 and only flew a DA-20 in a previous corp. job that had reversers and the chute was removed. From the stories I heard told the chute was used almost solely for stopping on a cluttered runway and more than one guy pulled the deploy handle only to have the chute fall out of the tail covered in ice and never open.

Actually from what I was told that was part of the deal...Fedex helped Canadair get going and in return they got a couple as corp jets in the end.

The U.S. Coast Guard's HU-25A Guardians (Falcon 20s) have chutes because they were delivered without thrust reversers in order to keep costs down.

The Lears have a handle next to the FO for the chute if installed. The chute itself is located on the back side of the door to the hell hole. I think the idea is in the event of a hydraulic failure, you have something to augment the emergency brakes which have a 3 shot limit if memory serves. Been a while since I flew it, so that number might be off.

The challenger was actually designed as a freighter from the outset. FedEx wanted something that could expand after deregulation yet could already carry containers. Cargo was deregulated in 1977 (one year before pax) and Fred decided to start buying up every 727 he could since parts and pilots were easy to come by.

Canadair found a better use for the challenger as a business jet and it was later lengthened to create the CRJ.

No it wasn't.

The Challenger started life as a Bill Lear design, the Learstar 600, which was a business jet (Lear was by then no longer connected with the Learjet company). The concept was to combine a stand-up cabin with a supercritical wing and high bypass ratio turbofans. He sold the design to Canadair, who built a developed version of this as the CL-600. The freighter version was developed a bit later at Fedex's instigation. For the complete story, read "Winging It: The Making of the Canadair Challenger" by Stewart Logie.
