Worst Annual Ever? Cessna 310 Annual Inspection - Airplane Intel

coming up on airplane intel we complete an annual inspection on a 1972 cessna 310-q we've got our work cut out for us and there's no shortage of snags and surprises along the way we had to cut it off because the hinge pin is seized on there so strap on your work boots and grab your tools it's time to get to work hey what's up you guys adam here i'm standing in our hangar at our headquarters here in ocala florida the ocal international airport and you're about to come with me to do an annual inspection on this tesla 310 right behind me hey but before we get there i need you to do me a quick favor go ahead and hit that subscribe button for me right now only about 10 of you are actually subscribed to this channel and that's quite disappointing because i've been doing this channel for about five years and it has not grown to the level i thought it would so please do me a favor hit that subscribe button right now i'd love to grow this channel to 20 000 subscribers before 2022 which is right around the corner so that would really help me out because it gives me a reason to keep doing these videos right if there's only a few people watching and a few people subscribe to the channel not a lot of uh good reason to keep doing these videos so i'd really appreciate it and it'll help other viewers like you find the channel so hit the subscribe button now and then join me for the annual inspection on this session 310. the cessna 310 is a light twin-engine piston-powered aircraft built by cessna aircraft company the aircraft was introduced in 1953 with deliveries starting in late 1954. a total of 5449 310s were built before production ended in 1980. over the years of production the aircraft has received many improvements and upgrades including more powerful engines increases in gross weight and aesthetic changes the 310q model was built from 1970 to 1974 and featured two continental i o 470-vo engines delivering 260 horsepower each the q model saw an increase in gross weight to 5 300 pounds giving it about a 2 000 pound useful load and about a 1 500 pound full fuel payload the aircraft cruises around 190 knots at 75 power burning about 25 and a half gallons an hour with its 102 gallon fuel capacity the 310 q has an endurance of just shy of 4 hours or 700 nautical miles now that you know the history join me for the annual inspection on this cessna 310 cube the one all the way back there that cessna 310 that's one we care about that is raja's cessna 310 and it's here for an annual inspection so as you can tell we do a lot of different things for our clients with the idea of providing complete support for them uh from the purchase through ownership and through selling their airplane and so on so we do a variety of maintenance activities here for uh all of our clients airplanes including you know the piston airplanes as as well as the turbine airplanes so today we're going to be doing the annual inspection on this 310 we've already gotten a pretty good start on it already uh you can see that we've got a couple panels open we're still working on that jonathan's back there working hard getting the airplane opened up in just a minute i'm going to be starting with pulling the counties on the engines and taking a look at the engines real good doing the compression testing the borescope oil filter inspection checking the mag timing and then checking the overall condition of the airplane of course we'll be using the cessna 310q checklist to kind of help us out with that as well as all the applicable fars that are involved with the 200 annuals so got a lot of work ahead of us it's a lot of airplane to look at believe it or not and so we'll take you along part of the journey with us airplane will be here with us for about another week or so so anyway strap in and we'll talk to you soon [Music] foreign [Music] so [Music] i got [Music] hey what's up guys hey we're here now at the engine the right-hand engine of this uh cessna 310. we've already done compressions on the engine they were okay we got a couple things to look at there uh we've bore scoped the right cylinder bank which is the odd cylinders and now we're about to bore scope the left cylinder bank which is all the even cylinders so i guess i'll show you how we're doing that we always like to do a good bore borescope inspection on the cylinders when we have an airplane whether for annual inspection or pre-buy not a lot of people do it it's uh it does take a few minutes to to learn kind of what you're looking for and what you're looking at but it's a pretty easy process we got this borescope here so we got the spark plug holes removed from when we did the compressions i got the cylinder in the position that i like so now i just kind of stick it down the top spark plug hole and i don't know how well this is going to come out but we got the computer set up here showing us uh what we're looking at here so let me get the borescope rotated around correctly so this is the top of the piston that we're looking at let me get it realigned here so we're looking at the top of the piston see a few things there so i'm going to take some pictures of that and then i'm just going to bring this borescope further down into the cylinder looking at the piston in more detail also starting to look at the cylinder walls seeing if i see any pitting or corrosion or or dings any gouges any oil pulling things like that and you just kind of learn how to manipulate the borescope to see what you want to look at you can always pull the bore scope out some to get turned around here and this bore scope articulates 180 degrees which makes it a little easier and then as i'm going here i'm just taking pictures some minor pitting corrosion there you can always adjust the light so that it's not shining and overexposing the shot there the most interesting thing that you can see doing this though is the valves so when you rotate the borescope 180 you can actually see the valve so here's your intake valve here take a nice shot of that there's your bottom spark plug we'll remove that later to clean it but for now we got it in there and oftentimes you'll see oil pulled up in this area this is the low end of the spark or of the cylinder and if there's any blow by coming from either the valve guide leaking or from the rings you'll see some oil build up there and that files the plug up pretty good and this is your exhaust valve and that's actually it doesn't look like it but that that's actually a good looking exhaust valve the analogy that people like to use is it looks like a burnt pizza and that's that's correct and it's even so the color is even there's no discoloration there's no green or anything like that and so that looks decent don't see any issues with its sealing another thing that we'll do is we'll spin the prop and that'll move the valve uh it'll start opening the valve and then we'll be able to see whether there's any issues with the valve seat that takes a little bit of manipulation though because as you're rotating the prop the valve will open but the cylinder will the piston will move also so you got to position it right so anyway that's what i want to show you for now we do that on all the cylinders on both engines and it kind of works in conjunction with the compressions continental has a surface bolton on this sp03-3 that goes into detail on how to do this inspection and how to interpret the data so just want to show you that real quick [Music] [Music] so this airplane is going to be a little bit different than a normal annual because there's a few squats that need to be taken care of that require us to remove the elevators and one of the flat panels and the reason for that is just some corrosion that we need to clean up and take a better look at in fact we're going to have to replace the right hand inboard flat panel because of some corrosion and some other damage to it that's beyond limit so having to do that is a little bit extra steps that we have to take it takes a little bit of time of course in fact we've got that right hand inboard flat panel off now we had to cut it off because the hinge pin is seized on there so we had to cut it off pull it out and very carefully of course that was quite the operation i'll throw some b-roll in for that but uh anyway we got a replacement flap that we're about to throw on uh the elevators like i say same deal we had to remove some corrosion on those but a little extra stuff that we have to do once in a while on these annuals just to make sure that they're airworthy and safe and going to last the owner and perform well so anyway that's kind of where we're at with that and we'll check in with you guys later [Music] so as you can see we have the left hand and right hand elevators removed now that went pretty smoothly overall basically you take the end cap off the elevator part portion itself you disconnect the trim tab push pull rod disconnect these bond jumpers here two on each side disconnected the torque tubes that actually weld it to the elevator itself remove those and then you remove these two [Music] hinge bolts here starting with the outboard and then getting the center one which is also the inboard and in case you've never seen this before this is the mechanism that controls the elevator so the elevator bolts on right here on either side so the torque tube for the right handleball board bolts on here and the torque ii for the left-hand elevator bolts to the other side of that and this is the mechanism that actually rotates up and down which move the elevator you can see the push pull tube right here and then that goes down in here to a bell crank where the cables are hooked up to the control column going forward so you can see that that's kind of how that works pretty simple overall really but uh yeah just gotta be careful not to damage anything like the rudder or the uh move the rigging on the trim we actually have to adjust the rigging anyway so not too worried about it at the moment but you can see we had to remove this elevator on both sides because there's actually some surface corrosion on the elevator itself kind of all over it so some of it we would would be inaccessible if we just left it on also the mount hinge hardware was corroded and some of these hinges are actually kind of corroded too so we're going to have to fix that up real good and make sure that we don't have any serious corrosion back here yeah so this airplane just needs a little tlc that's what we're trying to give to it now so anyway that's all for now guys [Music] so now i thought i'd give you a quick kind of update as to what we've done so far in general so when we got the airplane first thing we did was do a thorough pre-flight on it and then we ran it we ran all the systems we ran the engines and we ran it for a while and we wanted to make sure that there weren't any other squawks to work out and we needed to get the engines hot enough that we can do the compression tests and things like that we did find some some other squawks as a result of the run including a magneto that was timed incorrectly it only had 60 hours on it so since overhaul actually was it was a new magneto so we thought for sure we had a timing issue and sure enough we did so we looked into that we found that the right hand alternator was uh not putting out anything and it was actually an old alternator had been on the airplane a long time about 25 years or something like that so we ended up troubleshooting that and finding that the alternator was bad so we replaced that we also replaced the left-hand vacuum pump because it wasn't providing us with any suction so we did a little troubleshooting and found the vacuum pump was in up and of course we replaced all the filters and consumable items that you would normally replace on an annual or at an hourly interval so we got caught up on all those things so after we ran it we brought the airplane inside we gave it a bath wash it down then we opened it up as you saw we were doing that with jonathan we got started with him and then between the rest of us we were able to get the airplane all the way opened up from there we started going through the annual inspection checklist working squawks and uh i'll show you a second some of the squawks that we've been finding and i'll show you kind of the updated work order to see how that's uh basically grown from you know a handful of items to where we're at now but we are moving forward and working through everything so that's always good news and before i show you the book let me show you this flap real quick that i mentioned a minute ago so i mentioned that we had to replace the right hand inboard flap and that's kind of where i'm sitting now so the outboard is over there inboards over here and the reason for that is you see the exhaust is right there and that blows a lot of hot air hot exhaust gases as well as oil and other things onto the flap when the flaps are extended so what that can do over time is create corrosion issues and heat damage issues and things like that in addition to typical flap wear that you might see you know cracks from from the flaps being extended uh too high speeds and you know just not not following some of the operating limits so that's exactly what we found here the original flap had some cracking in it and some you know in my opinion excessive heat damage and some corrosion damage so we opted to replace it this is not a brand new flap this is a serviceable flap that we were able to find and uh you might notice if you're real keen that the the paint doesn't match perfectly but that's uh really not a big deal these are split flaps you know that you don't see the flap up up here when the flaps are shut you only see them when they're down and it's not really that bad of a match unless you're real close to it but we did have to replace the hinge pin i don't know if you can see but the hinge pin it's a piano hinge type system and you see the safety wire there so we safety it so that it can't fall out but this hinge pin runs all the way down uh these hinge lines down here so that was interesting to take off because there was seas down there originally on the original flap so we had to cut it off and that was quite the operation had to be real careful not to cut into the airframe or cut into the airframe side of the hinge itself so it's definitely kind of a tight squeeze so maybe if i get underneath the airplane you'll get a better view of what i'm talking about here so yeah here's the the hinge itself and like i said we had to cut the flap side to get the pin out because it was seized so we replaced that it's good as new now and then what we did is we took the scissor hinges here and put those back on check those out make sure they were the bearings were good and the bushings were good and all that and then so we were able to reuse the scissor hinges so this job is all done flap stop check good the travels are good all the rigging is good so we can move on from from the flaps so hopefully that gives you a little bit of understanding as to all the things that go on for a typical annual inspection and then some of the things that might happen that are outside of a normal annual so all in all things are going pretty smoothly what we have left to do uh we have some squawks to finish we have to finish the annual inspection checklist and we have to among that is putting the airplane on jacks so we're going to have to jack the airplane and remove the wheels look at the wheels and the bearings on the wheels and replace them if necessary otherwise clean them and re-grease them and then once that's done we'll go ahead and cycle the landing gear up check the landing gear check the rigging on the gear and things like that and do the emergency extension so those are some big things that we have left that will be continuing to work and we'll be sure to include you in some of those things as well as we move along here so anyway we'll talk to you guys in a little bit [Music] hey what's up you guys it's uh getting late in the day now it's about 7 30 p.m and i wanted to give you a quick update on this 310. you see we got it jacked up we got the wheels off we have inspected the wheel bearings and they looked good but we did find that the brake lining and also the brake discs were worn beyond limits so we ordered some brake discs and some lining and we expect to get those in the next day or two and then we'll finish up this landing gear we also found that the calipers were leaking on both sides so we gotta replace the o-rings on those as well so anyway that's kind of where we're at and you see uh always a lot of things going on things are moving along and we'll keep going with this and catch up with you later [Music] hey what's up you guys well as you can see the 310 is back on its feet we got the wheels back together got the brakes all situated and we're now uh getting close to wrapping this thing up we're starting to close the airplane up and get this thing out of here it's been here for quite a while actually and hopefully it'll be gone uh sometime mid next week it's a friday right now it's about 6 30 p.m and we've been pushing pretty hard on this airplane so in a minute i'll show you some of the things that we found some of the squawks and items that we found as i mentioned earlier that this airplane needed some some tlc it's an airplane that was new to us we had never seen it before worked on it before so we had to kind of get familiar with some of the quirks of the particular airplane based on its history and everything and i think now the owner's going to be real happy with it because it's it's all in good shape now [Music] [Music] [Applause] [Music] all right well that's all there is to it we got this annual inspection done i couldn't have done it without your help so thanks for coming along with me i appreciate it the airplane is looking good now it was a lot of work and took a lot of time but all in all the airplane looks good and i was very happy to be working on this airplane for for the new owner we have just completed our final internal checklist our post maintenance checklist and our return service checklist law book entries are done all we really have left now is to just wipe off our nasty fingerprints off of some of the paint and the panels and whatnot but that's it that's it so until next year anyway when the airplane comes back we'll continue to keep you know working some of the other squawks here and there and some of the deferred items that we had found but all in all the airplane is in real good shape it's got excellent bones and i know that the owner's going to be happy with it in fact he'll be coming on wednesday to pick it up today is saturday yes i'm here on a saturday but he'll be here on wednesday to pick up the airplane so i look forward to seeing him and delivering this 310 to him so thank you for riding along with us i appreciate it and i look
