It’s likely an AN7-40A (original … 41A with a shim in), looking at the IPCs for ‘70-86, but I didn’t check them all 🙂

What year/model?

SEB83-14 has the info on shimming the engine mounts. It’s P/N S1450-7N32-125 for the washer/shim and you have to go up 1 bolt length for each shim used.

It absolutely should, other than the TruTrak isn’t legal to couple on an approach.

”This autopilot has not been evaluated by the FAA to meet the certification requirements for coupled instrument procedures, including coupled approaches. Therefore, these types of procedures are not authorized without further evaluation and approval.”

Find a used carry-through that can pass and pay for a lot of labor to change it, or wait for Cessna to offer their new design carry-through  (assuming they actually take that all the way through to production) and maybe pay slightly less $ in labor to change it (maybe, I’m making assumptions here that it’ll be a direct replacement and can be matc…[Read more]

You say with the gear appearing to be fully down… is it in fact fully down but you just aren’t getting a green light? If all 3 downlock microswitches aren’t made then the green light doesn’t come on and the pump will not shut off. Those microswitches are very susceptible to becoming intermittent as they age, as well as having breaks in the…[Read more]

From your picture it appears you only painted and Corban’d the lower cap of the carry through (or is that just an in-progress pic)? The SEL (referenced by the AD) calls for the entire surface to be painted and Corban’d.

I’d recommend taking a look at the resistance between engine block and battery negative terminal. It doesn’t take much corrosion on the bonding straps to get increased resistance there and with the amount of current the starter is trying to draw, can make a big impact. I’d also recommend checking the power side of the circuit too, esp the voltage…[Read more]

The port is essentially unregulated pressure and is too high pressure for the O2D2 directly. You need their kit with the inline pressure regulator: https://www.mhoxygen.com/product/o2d2-x-str/. It doesn’t cause any issues on the system at all, works great and make a fill last a really long time as you are basically only being given oxygen when it…[Read more]

O2D2 is awesome, highly recommend it. Makes a fill last an extra, extra long time. What year is your plane? If it’s a 1980 model year or newer, it’s the BNC 750, if you are earlier, its the BNC 566. My T210L takes the BNC 566 and my friend’s late ’79 T210N (’80 MY) takes the BNC 750.

Got any prop shops near you? A lot of them have the equipment and training to do eddy current inspections in a mobile fashion for the various prop hub ADs out there that require eddy current every 100Hrs.

I don’t know what happened to it, but Icom used to sell a switchbox, that exposed a 3.5mm jack on the panel and that when plugged in would physically disconnect the normal connection and provide a direct connection to the external antenna. Used to be around $75 or so, but I can’t find it on Spruce or Sporty’s etc, might have been discontinued.…[Read more]

Do you have the VNAV feature enabled, or just VCALC? Do you have barb-corrected altitude fed to the GTN750 from somewhere (G500/TXi/G5/G3X)?

John Efinger: https://www.cessnarigging.com

No problem per se, the 3100 can’t do enroute VNAV though 🙂 Only the GFC 500 and 600 can read the GTN VNAV labels right now. Genesys has said it’s definitely under investigation though.

No, using the separate encoder over RS232 to the L3 should not impact the other interconnects between the L3 and the Aspen. Standard interconnect would be a 429 that is paralleled at the L3 to the 429 pressure alt and 429 AHRS inputs and an RS-422 from the L3 to the Aspen for traffic and weather. Selecting the RS232 encoder for the pressure…[Read more]

I do not believe so. I’ve only installed one NGT9000 but my recollection (and the install manual confirms it) that the software only allows you to select a single source, and not multiple with a priority list like the Garmin transponders do. You’d be sending 429 data from the Aspen to the L3, and RS232 from the encoder to L3, so a switch isn’t…[Read more]

There are 2 diodes the come off the small pin. One feeds the avionics cutout relay and prevents the starter cutout to the avionics relay from back feeding to the GPU contactor and the other is to theoretically prevent a plug with jumper cables attached backwards from opening the contactor and frying the system.

If you have power to both of those…[Read more]

I’d just check voltage with a DMM to the input side of the contactor and coil, if you have 12V on both of those and 0V on the output side of the contactor, try some light percussive maintenance on the top of the contactor and reconnect, see if it opens then.
