Bell 505 Maintenance
 

Anyone have any idea what the scheduled maintenance is on these machines? Major component times? Are there any calendar items?

Hi

I can help you with that, send me a dm and I will forward what you need

Anyone had a problem with the 505 tail rotor control cable pulley? My port aft has just cr@ped out on me. Any advice appreciated.

apparently I must send 8 posts before I am allowed to attach an image. So...

I would suggest that is impact damage caused during installation or maintenance.
Fit a new pulley and soldier on.

The 505 wasn't modelled as a progression from the B206 "Jet Ranger".

To me it looks like they used the B47J "Ranger" as a starting point? All steel tube and screws.

505 from 47J
 

To right regarding the J as the original! That pulley looks very much like what is on the 47. What's the part number?

Heh. When I first saw the 505 with its steel tube frame covered by sheet metal, I thought to myself how similar it was to things that Bell had built before. Like the 47J. I laughed and thought, "This thing is just a gussied-up J-model!" Only uglier. Way, waaaaay uglier. And let's not forget, in 1962, Bell built a J-model with a turbine engine! That would be the HUL-1M, powered by the (then) 250 h.p. Allison 250 engine. Okay, but,..but...the 505 is such a great leap forward in "technology." Right. Like, uhhh, what sort of new tech? Oh yeah, it's got FADEC on the French engine. Aaaaaand...hmm...what else? Well, at least it's got a flat floor! Man, when it comes to helicopters, there is really very little "new" under the sun.

That's what Jason Hill is here for.

For what it’s worth, the appearance of innovation is often an illusion and the lack of apparent innovation is often due to poor messaging. Any aircraft certified in the last 15 years has a number of technology improvements that are inherent in their updated certification basis. These tend to show up as material changes to advanced metals and composites, electrical system changes to protect against lightning, HIRF and various electrical faults, as well as the many redundancy and simplification improvements you see in a modern glass cockpit. Passenger and crew seat crash, head strike, and egress requirements and certification compliance are substantially more complex in modern helicopters versus the previous generation. Be careful with perceived innovation…

the j had a flat floor too.

There's nothing digital about an autorotation (yet). I trust the tubes & wires any day on a 47, a Lama or a 500 to keep me in one piece during an unanticipated landing over an android operated system or some composite. Horses for courses I guess.
