We enter our 9th month tomorrow without a CDM.(august 2023 the PO was put in) We were initially number 9 on the list that grew to 70 units if I remember correctly on my last check. We have serviced the aircraft inside of an Embraer Service Network and are on EEC. Finally we received a CDM that was overhauled and I'm sure that it's no surprise - It doesn't work. Embraer's response is next March 2025 for another CDM. Anyone else have any suggestions here?

At EOC this year they highlighted the new -10 and -11 CDM coming to market in June 2024. They implied that it will help clear the backlog quickly with the improved reliability.

Depending on which version of the CDM you have now, make sure you have the matching Temperature Controller or it will fail pretty quickly.

Our CDM went out last week with a lead time of June 2025…We also just had it replaced last April so we made it just over a year (on a 2021 airplane) just curious if anyone has seen the new dash numbers delivered or what the recent experiences with lead time have been.

We have heard multiple stories like this around different parts for the Phenoms. If I was Embraer I would be figuring out every path possible to get these fixed and people flying again. Seems like the big company phenomenon of, "Meh, not my problem" has sunk in. Have you tried to elevate this to the CEO? I know some members on here have some contacts there.

No part that is required or critical for operations should go on longer than 1 week wait time without panic setting in at the company.

Perhaps as a group we should be negotiating a service level agreement with EEC instead of just taking the terms that they dictate. EEC should be guaranteeing part supply and aircraft uptime. Otherwise, why bother?

I am also curious whether embraer will step up and cover the labor and parts costs for the replacement of these obviously defective CDMs for those of us not on parts programs. Per Embraer’s specs, they removed a perfectly functioning CDM from my plane that had reached the 2,000 hours. I had two replacements fail in the 13 months since then and like others have had no A/C now for several months.

[Username Protected]

Do these failures occur early or late or both?

[Username Protected]

Both. I had one fail five weeks after being installed in my plane and another fail 13 months after being installed.

[Username Protected]

How many hours did you put on it during that 13 months, roughly?

[Username Protected]

Around 220 hours (sorry - should have thought to include that).

[Username Protected]

I am also AOG with a CDM failure.This is the second CDM that failed after we removed a perfectly good one. Months lead time to get a new one. Unacceptable.

So sorry to hear that, (Username Protected). I’ve had cockpit temps as high as 102 degrees at takeoff, and have resorted to paying for hangars the night before departure to try to keep the interior as cool as possible. The most frustrating thing about this is that they removed a perfectly operating CDM from my plane 18 months ago. The second most frustrating thing is that this has been a known issue for well over a year (I recall Chris Grinnell talking about it in our meeting in Boston). It seems that Embraer was slow to respond, and at a minimum should have stopped taking perfectly operating CDMs out of planes until they solved this. The whole situation is unacceptable and could have and should have been handled differently.

[Username Protected]

Yep exact same scenario for me. When the 2000 hrs came due, there were no CDMs available so I switched to 2000 hr CDM Hobbs instead (you can replace at either interval). A few months later the back ordered CDM came in, so proceeded to swap. The new one failed within a few months. Got a replacement one pretty fast, but it failed too about a year later. Argh.

Obviously we can’t use the plane for 135 ops without AC. Too expensive of a toy for me too sit idle.

[Username Protected]

So looking at the AMM Task 21-52-01-920-801-A, it appears that the CDM can be overhauled. I hear only of operators getting new ones. Has anyone sent theirs out for overhaul instead of having it replace with a new (and defective) one?

[Username Protected]

I am almost positive that the two defective units that Embraer installed in my aircraft were overhauled ones. I don’t think that they generally install brand new ones.

[Username Protected]

Any feedback on reliability and issues with the -10 CDM? Our original(-6 I believe) is coming up on life limit. Requested an ETD yesterday because it’s been working great with just regular annual servicing. Suddenly, there’s a new CDM and temp controller about to ship a year after preemptively placing an order to have it available in time to replace the current one. Our FSR had warned us specifically against taking a -9 as they were failing soon after installation. Is the -10 any better?

[Username Protected]

I do not have firsthand experience with the -10 (yet) but all reports from Embraer have been that they are working fine. The first few did not BUT that was because they were installed in planes where the prior unit had failed, and the system had not been flushed. As long as the system is fully flushed Embraer has said that the -10 units are working well.

[Username Protected]

I am also AOG with a CDM failure.This is the second CDM that failed after we removed a perfectly good one. Months lead time to get a new one. Unacceptable.

FYI we got the parts last week to convert the failed -9 into -10, the plane is now back in the air! Three months "soft" AOG.

[Username Protected]

Just for you all to have our timeline…We were also initially told about an expected delivery date for next year. We got it fixed a couple of weeks ago. Ended up being 2 months without a/c

[Username Protected]

It is not limited to the 300 The 100 has the same issue. Told 4 month waiting period Also number 4 on the list

[Username Protected]

That is so embarrassing for a 10+mm airplane. How can you not have parts?
What is amazing to me is that an airplane of such quality in design and original build can have these kinda of folks running the company!!! It swayed me from the very limited embraer infrastructure to the lesser limited textron infrastructure.

For the dollars being spent it’s beyond ludicrous to even be talking about this. These folks would make so much more being better organized.

Try around $14M if you're talking about a recent new production slot. It’s only getting worse with the fleet size. We’ve either hit or will soon be hitting SN#800 in the 300. Support infrastructure has never been great and it still lags behind. Couple that with the fact that the big fractionals have guarded parts pools. We had a gear part that was found bad during our 120-month and gear overhaul that was going to ground us until next April, but was available in one of those pools and they wouldn’t release one to us. It took over three weeks to get engineering approval to service the part which then was further damaged during repair. MRO was finally able to locate a serviceable used part just before RTS.

I'm incredibly surprised that the group here has not raised sufficient pushback to change Embraer and their attitude towards owner flown aircraft. It cost them a sale from me. I simply did not want to be in the infrastructure. This continues for the next 6-12 months and there will be a number of cheap 300's on the market. You simply cannot have an airplane grounded for any length of time. They're building and supplying airplanes, what is the logical reason for them not having basic parts. Has anyone here asked why they do not have a simple part for an aircon unit?

It just boggles my mind.

we should expect and demand more from a company of this size with almost 1200 combined 100/300 platforms in the air.
it does discourage one from purchase, for sure.

Easy to answer, it's because it's a sub-contracted module, and they cannot make them fast enough for the failures that have happened. What has put everyone on the back foot, was the number of "repairs" completed where the compressor was replaced, but the whole system was not flushed properly (due to engineering not following the correct procedure) that lead to further failure within 1-5 hrs on numerous machines. This further increased the problems and lack of availability.

Embraer are pouring a lot other time, effort and money into rectifying this as quick as possible. It's far from ideal on such an expensive aircraft.
