Cage: 47MZ7 Document Title: FAA Approved Model List (AML) for STC Number ST11283DS 1. Introduction This document is the FAA approved model list (AML) for supplemental type certificate (STC) number ST11283DS, for the installation of Aviation Clean Air (ACA) aircraft ionization units in eligible Part 25 aircraft. Revision to this AML must be coordinated between the STC holder and the responsible ODA/ACO and requires ODA/FAA approval. Limitations and Conditions (continued from page 1 of the certificate): 2. If the holder agrees to permit another person to use this certificate to alter a product, the holder must give the other person written evidence of that permission. 3. The FAA has reviewed the applicant’s assessment showing that this modification does not impact the existing electrical wiring interconnection system instructions for continued airworthiness (EWIS ICA) and found that no additional EWIS ICA tasks are required. 4. This modification shall not be incorporated onto aircraft equipped with ionization smoke detection systems. To be eligible, ionization smoke detection systems must be replaced with non -ionization smoke detection systems prior to the incorporation of this modification. 2. Certification Basis The certification basis for each model qualified for this modification is detailed below: Based on 14 CFR §§21.115 and 21.101, and the FAA policy for significant changes in FAA Order 8110.48, the certification basis for the AML STC modified by installing ACA aircraft ionization units in eligible Part 25 aircraft is as follows: a. The certification basis for the approved model list is shown in the respective Type Certificate Data Sheet (TCDS) for parts not changed or not affected by the change. b. The certification basis for parts changed or affected by the change since the reference date of application, May 11, 2021 for the following aircraft is as follows: Aircraft Make Aircraft Model Type Certificate Data Sheet Certification Basis from TCDS Certification Basis of Parts Changed A320 A321 Regulations at the latest amendment 25-0 through 25- 146: 14 CFR §§ 25.832(a)(b)(c) Amdt. 25-94, 25.854(a)(b) Amdt. 25-74, 25.1581(a)(b)(d) Amdt. 25-72, Airbus SAS Excludes: A28NM 25-0 through 25.1585(a) Amdt. 25-105 A320-()N, A321-()N and A321-()NX 25-56 Regulations at an intermediate amendment: 14 CFR §§ 25.561(a)(b) Amdt. 25-64, 25.869(a)(4) Amdt. 25-72, 25.981(a)(3) Amdt. 25-125 S-1 Issue Paper, Installation of Cabin Disinfection and/or Air Cleaning System Template: OPT5001 Rev 01 ST Engineering STC Number: ST11283DS Revision: - Page: 4 of 4 Organization: VT DRB Aviation Consultants A division of VT San Antonio Aerospace, Inc.
