JohnRich 4 #1 January 22, 2005 What is it? (Whatzit?) This aircraft part (image attached) is about the size of a McDonald's Big Mac, costs $7,000 to replace, and when it is not working, prevents an engine in a Twin Otter from starting. And the nearest replacement part is a four-hour drive away. There will be no jumping from this plane today... Whatzit? Quote Share this post Link to post Share on other sites

slotperfect 7 #4 January 22, 2005 It's a Flux Capacitor. Maximum output is 300 jigawatts.Arrive Safely John Quote Share this post Link to post Share on other sites
PhreeZone 20 #5 January 23, 2005 That would actually be a max output of 1.21 Jiggawatts Booster pump?Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites
Travman 6 #6 January 23, 2005 I'm thinking a hydraulic pump, or maybe an oil pump. There are a lot of hoses coming off it. Quote Share this post Link to post Share on other sites
ssmi 0 #7 January 23, 2005 Well john!!! That would be an egciter box, that has replaced igniters on most PT6's. In the $4000. range Quote Share this post Link to post Share on other sites
jerm 0 #8 January 23, 2005 QuoteThat would actually be a max output of 1.21 Jiggawatts Booster pump? dude... i'm dissapointed..... flux capacitor needs an INPUT of 1.21 gigawatts..... sheesh!!

Hooknswoop 19 #9 January 23, 2005 Quote Well john!!! That would be an egciter box, that has replaced igniters on most PT6's. I see what looks like fuel on the deck. Could be turbine oil though. I see 3 either input or output fluid lines. The control arm. I can't tell if that is for input, like controlling pump output, or if it is for output, for controlling, say prop pitch. I see what looks like a filter housing and a spline shaft for driving a pump. I don't see anything electrical about it. I really don't think it is an 'egciter box' or an exciter box either. I'll still go with a fuel control and pump. Derek Quote Share this post Link to post Share on other sites

JohnMitchell 16 #11 January 23, 2005 It'd be $29.95 at Checker Auto, but it says "airplane" on it, so it cost a Gazillion dollars. I've fixed a jump plane before with car parts, and it worked pretty well. I think the statute of limitations has run out on that one, I think. Quote Share this post Link to post Share on other sites

ssmi 0 #17 January 23, 2005 Hey John, I didn't look at the picture before, that is a fuel control unit and they do run 6 to $7000 for replacement or overhaul. The fastest and most cost effective I have found is a place in Miami and yes Derik is right it is not an "Igciter" box.

JohnRich 4 #20 January 23, 2005 QuoteMy guess was going to be the FCU... I don't know this myself, but the A&P (aircraft mechanic) working on the engine said it is indeed, the fuel control unit. He described it as the "heart" of the engine. It's amazing that something so small, can cost so much. It has safety wire all over it, and the ends of the safety wires have crimped lead seals on them, indicating that it was built in a certified shop, so I'm told.

Hi Marcus! Yep, it's Skydive Houston's Super Otter. It happened Friday afternoon, but fortunately during startup on the ground, and not in the air.

JohnMitchell 16 #22 January 23, 2005 Talking to our DZO one day and she said that, since going turbine, she was getting used to writing checks for parts that used to buy an entire jump plane. Ouch! Turbines are great, but when they break, oh boy. Quote Share this post Link to post Share on other sites

FrogNog 1 #24 January 24, 2005 QuoteIt's amazing that something so small, can cost so much. How does its price-volume ratio compare to the other parts of the jet engine? Its price-mass ratio would be interesting, too; some parts of jet engines can be expensive, large, but light. -=-=-=-=- Pull. Quote Share this post Link to post Share on other sites

Having a FCU runaway can be a bad thing because the old statement of "dead foot dead engine" doesn't work anymore. You could have a runaway over power engine and think the "good" engine is failing and feather it. Bad deal. Now you have two bad engines and it ain't easy getting a shutdown PT-6 back to flying status quickly in flight. I've not had one go on me but others say they see fuel flow fluctuations just before it goes away. Always helpful to keep that instrument scan up!Chris Schindler www.diverdriver.com ATP/D-19012 FB #4125 Quote Share this post Link to post Share on other sites
