We accept your statement certifying your article meets the requirements of TSO—C112d, C166b and that you meet the requirements of Title 14 Code of Federal Regulations part 21 subpart 0. Effective the date of this letter, we authorize you to identify the following NXT Release 1 Transponder configuration with the marking requirements defined in 14 CFR § 45.15(b) in TSO—C112d and C166b. Part Number End Item Drawing S/W Mod Level H/W Mod Level TsO TSO—C112d (Level 3adens, Class 1) & 9006000—55000 9006000—55000, Rev A « — TSO—C166b (Class A3 Transmit Only) w/dev Your Quality Control Systems, as defined in your Quality Control Manual, currently on file at the Phoenix Manufacturing Inspection District Office, is considered satisfactory and complies with CFR § 21.607 for production of this article at your Phoenix, AZ 85027, facility. As required by the TSO, the following statement must be furnished with each manufactured unit: "The conditions and tests required for TSO approval of this article are minimum performance standards. It is the responsibility of those installing this article either on or within a specific type or class aircraft to determine that the aircraft installation conditions are within the TSO standards. TSO articles must have separate approval for installation in an aircraft. The article may be installed only if performed under 14 CFR part 43 or the applicable airworthiness requirements".

This letter also constitutes a deviation approval for the following: (1) TSO—C166b: Section 4(a)(b)(e) Marking Requirements (2) TSO—C112d and TSO—C166b: DO—160G, Section 21.5 Radiated RF Emissions This TSO authorization, issued under 14 CFR § 21.611, is effective until surrendered, withdrawn or otherwise terminated under the provisions of 14 CFR § 21.613. With notice, we may withdraw this TSO authorization if articles are not in compliance with the applicable TSO performance standards per 14 CFR § 21.2. You must obtain FAA approval prior to making any changesto the location of your manufacturing facilities pursuant to 14 CFR § 21.609(b). Without further FAA approval, we don‘t allow manufacturers to mark articles after they change their company‘s name, address, or ownership. You must notify the ACO and MIDO of name, address, or proposed ownership changes. Per 14 CFR 21.614, a holder of a TSOA may not transferit. If you wish to transfer it, you must request a transfer from the FAA. Send to the office below any design change(s) for this TSO article as outlined in 14 CFR 21.619(a). You should notify us of minor design changes within six months. Also, as recipient of this authorization, we require you to report any failure, malfunction, or defect relating to articles produced under this authorization in accordance with the provisions of 14 CFR 21.3. The report should be communicated initially by telephone to the Supervisor, Technical and Administrative Support Staff, ANM—103L, (562) 627—5300, within 24 hours after it has been determined the failure has occurred and followed up with a written notice.
