| ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes | 170-21-0017, Revision 01, dated February 15, 2006. |

The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 and ERJ 190 airplanes. This AD requires repetitive inspections to detect damaged smoke seals in the aft avionics compartment, repair/replacement if any damage is found, and reinforcement if no damage is found. This AD also requires eventual replacement of all smoke seals in the aft avionics compartment with new, improved seals having new part numbers, which terminates the repetitive inspections. This AD results from a report of damaged smoke seals in the aft avionics compartment of the affected airplanes. We are issuing this AD to prevent smoke from penetrating into the passenger cabin during a fire in the avionics compartment.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of the following service bulletins, as applicable:
(1) For the inspections, applicable corrective actions, and reinforcement specified in paragraph (g) of this AD: EMBRAER Service Bulletins 170-21-0017, Revision 01, dated February 15, 2006 (for Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes); and 190-21-0003, Revision 01, dated February 15, 2006 (for Model ERJ 190-100 STD, -100 LR, and -100 IGW airplanes); and
(2) For the replacement specified in paragraph (h) of this AD: EMBRAER Service Bulletins 170-21-0018, Revision 01, dated February 15, 2006 (for Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes); and 190-21-0004, dated December 2, 2005 (for Model ERJ 190-100 STD, -100 LR, and -100 IGW airplanes).
Within 600 flight hours after the effective date of this AD: Do a detailed inspection for damaged smoke seals in the aft avionics compartment; and, following the inspection, before further flight, reinforce around the Velcro fasteners by installing silver tape if no damage is found, and do all applicable corrective actions if any damage is found. Repeat the inspection thereafter at intervals not to exceed 1,200 flight hours until the replacement required by paragraph (h) of this AD is done. Where the applicable service bulletin specifies reinforcing around the Velcro fasteners by installing silver tape if no damage is found during the detailed inspection, that reinforcement must be done the first time; it is required again only if damage is found during any repeat inspection. Do all actions in accordance with the applicable service bulletin specified in paragraph (f)(1) of this AD. If any damage exceeds the limits specified in the applicable service bulletin: Before further flight, do the replacement in paragraph (h) of this AD.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
Within 6,000 flight hours after the effective date of this AD: Replace the smoke seal in the aft avionics compartment with a new, improved seal, having a new part number, in accordance with the Accomplishment Instructions of the applicable service bulletin specified in paragraph (f)(2) of this AD. Doing this replacement terminates the repetitive inspection requirements of paragraph (g) of this AD.
(i) As of the effective date of this AD, no person may install a smoke seal in the aft avionics compartment on any airplane that has part number 170-96563-509, -511, -513, -515, -517, -519, -521, or -523; 171-04768-501, -503, -505, or -507; 190-15062-501, -503, -505, or -507; or 190-15902-501, -503, -505, or -507.
Actions done before the effective date of this AD in accordance with the applicable service bulletins identified in Table 2 of this AD, are acceptable for compliance with the corresponding requirements of paragraphs (g) and (h) of this AD.
