NotarPilot Posted October 3, 2013 Report Posted October 3, 2013 Anyone here flying past engine TBO? If so, how many hours are you at? Does your IA have a problem signing it off at annual? Quote
jetdriven Posted October 3, 2013 Report Posted October 3, 2013 It's illegal. And it voids your insurance. 1 Quote
N601RX Posted October 3, 2013 Report Posted October 3, 2013 The Cessna we sold a few years ago is almost to 3,000hrs now and running fine with the original motor from 1967. Quote

jetdriven Posted October 3, 2013 Report Posted October 3, 2013 I was just kidding. But some people aren't 2 Quote
carusoam Posted October 3, 2013 Report Posted October 3, 2013 Byron, I thought somebody took over your account there for a minute.... -a- Quote
Scott Aviation Posted October 3, 2013 Report Posted October 3, 2013 In Canada it's called running the engine on condition and as long as it checks out the AME doing the annual signs it out for private and commercial use. I know a flying school that runs their engines well into the 2500-3000 hr range Quote
Sabremech Posted October 3, 2013 Report Posted October 3, 2013 I was just kidding. But some people aren't   Wew! I thought we were headed into another one of those threads! Quote
Shadrach Posted October 3, 2013 Report Posted October 3, 2013 I plan on going past TBO, but we've a ways to go... We're already past calendar TBO at 13yrs.  I have actually heard of IAs refusing to sign off an annual for an AC that is past TBO. Quote
jetdriven Posted October 3, 2013 Report Posted October 3, 2013 I'd find a new IA.  In fact my IA's Piper Arrow is at 20 years and 2000 SMOH, he signed it off. Quote
201er Posted October 3, 2013 Report Posted October 3, 2013 What's the point of talking about going past TBO? Everyone knows these engines are rigged to fall apart way before then anyway! 1 Quote
jetdriven Posted October 3, 2013 Report Posted October 3, 2013 If it was built between 1999 and 2004, TBO wont be an issue. The cam and lifters will fail long before then. According to what I've seen, around 1300 hours. Quote
jetdriven Posted October 3, 2013 Report Posted October 3, 2013 I'm currently at 1717 hours and 27 years since factory reman. I'm planning to run it 20 percent (400 hours) past TBO if it is still doing well when that time comes and continues to do so for the duration.  My IA balked at that idea when I first brought it up but he has since warmed to it. I've got a few more years to work on him so I'm pretty comfortable that he'll be ok with it by the time it matters. My 500 hour inspection on my D3000 mag comes due at 1900 hours, which factored into my plan.  Here's hoping . . .  Jim Fly often and Camguard. Also check out Don Muncy's dehydrator. 1 Quote
rbridges Posted October 3, 2013 Report Posted October 3, 2013 Fly often and Camguard. Also check out Don Muncy's dehydrator.  I started using camguard at my last oil change (850 smoh).  Quote
Sabremech Posted October 3, 2013 Report Posted October 3, 2013 1850 SMOH done around 1990ish and no Camguard. I guess I'm going to fall out of the sky! At this point there's no use in adding Camguard or any other additive for that matter. Planning on operating it until it requires maintenance. Quote
DAVIDWH Posted October 3, 2013 Report Posted October 3, 2013 2450 on io550 Â Afraid to touch it when running so well, good compression, no metal in screens, regular oil analysis. 2 Quote
1964-M20E Posted October 3, 2013 Report Posted October 3, 2013 Run on condition. currently <1000 hrs SMOH Quote
aaronk25 Posted October 3, 2013 Report Posted October 3, 2013 I'm gonna run 4000 hours. My 1300 hour engine got a cam and lifters during prop strike but at 200 hours a year you boys are gonna have to hang around for a while to wait and see Quote
DS1980 Posted October 4, 2013 Report Posted October 4, 2013 Two out of three ain't bad! I don't dehydrate but I have considered it. Will revisit.  Jim Jim, In the meantime, a trick I learned was to simply unscrew the oil filler cap right after shutdown and lean it to one side. It's surprising how much smoke and moisture rise out.  Oh yea, gotta stay on topic. TBO is a # that is the result of many hours of study and..........................oh I got laughing too hard to finish. Quote
fantom Posted October 7, 2013 Report Posted October 7, 2013 Me too...... Two out of three ain't bad! I don't dehydrate but I have considered it. Will revisit.   Quote
Earl Posted October 8, 2013 Report Posted October 8, 2013 Mike Busch has written a lot on the issue of TBO. Â In one of my EAA mags he laid out a very good plan for proactive maintenance and monitoring that assuming no warning signs should allow you to fly safely past TBO. Â Was pretty adamant that you do all the suggested monitoring faithfully. Â And I thought not filing a flight plan voided your insurance and it had nothing to do with being past TBO.......dang it! Â I had it all messed up........ Â I hate when that happens. Quote
flyboy Posted October 8, 2013 Report Posted October 8, 2013 Plenty of O360's out there running with over 3000 hours Quote
N9453V Posted October 9, 2013 Report Posted October 9, 2013 My O-360-A1D has 2058 hours since factory reman in 2004. Compressions at the last 100hr were 75/70/74/70 and oil consumption is about 1 qt every 10 hours. I do oil changes every 50hrs with W100 and CamGuard and send a sample to AVLAB in New Orleans. I don't plan to overhaul anytime soon unless something dramatically changes. Â -Andrew Quote
