Applicability*9
This AD applies to Embraer S.A. (Type Certificate previously held by Yaborã Indústria Aeronáutica S.A.) Model ERJ 170-100 LR, -100 SE, -100 STD, and -100 SU airplanes, and Model ERJ 170-200 LL, -200 LR, -200 STD, and -200 SU airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2023-11-01, effective November 21, 2023 (ANAC AD 2023-11-01).
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2023-11-01.
Unsafe condition
This AD was prompted by a manufacturing quality escape concerning some overheat detection system (ODS) sensing elements. The FAA is issuing this AD to address defective sensing elements. The unsafe condition, if not addressed, could result in a sensing element not being able to detect a thermal bleed leak, which is a latent failure, and depending on the affected area, may start an ignition source in the fuel tank, which could damage some electronic boxes and expose the wing structure to high temperature gradients and unexpected thermal loads, which could result in reduced structural integrity of the airplane.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
