The PDF is the record. Part *23 of the Federal Aviation Regulations. (*Certification basis is set forth in Type Certificate Data Sheet) Description of Type Design Change: Installation of Universal Avionics Solid State Data Transfer Unit (SSDTU), P/N 1408-( ), operating software SCN 10.X, in accordance with FAA Approved UASC Master Drawing List, Document No. MDL-2010-1001, Revision “03”, dated 28 January 2011, or later FAA approved revision. The Instructions for Continued Airworthiness (ICA) is called out in the above referenced Master Drawing Lists (MDL). Limitations and Conditions: This approval should not be incorporated in any aircraft unless it is determined that the interrelationship between this installation and any previous approved configuration will not introduce any adverse effect upon the airworthiness of the aircraft. Limitations and Conditions continued on Page 3 The FAA will reissue the certificate in the name of the transferee and forward it to him. Transfer the ownership of the Supplemental Type Certificate Number to (Name of transferee) (Address of transfer) (Number and street) (City, State, and Zip code) from (Name of grantor) (Print or type) (Address of grantor) (Number and street) (City, State, and Zip code) Extent of Authority (if licensing agreement): Signature of grantor (In ink): Limitations and Conditions (Continued) This AML STC requires that one of the following Universal Avionics Data Transfer Units (DTU or DTU-100), and all of its interfaces, be previously installed and approved by Type Certificate (TC), Supplemental Type Certificate (STC), or FAA Field Approval in the subject aircraft. This STC will remove one of the DTUs listed below and replace it with a Universal Avionics Solid State Data Transfer Unit (SSDTU) P/N 1408-( ). The SSDTU must be installed in the same location vacated by the removed DTU, using existing electrical power, ground, and interface wiring. Description Part Number Software Data Transfer Unit (DTU) 1403-( ) Any Data Transfer Unit (DTU) 1405-( ) Any Data Transfer Unit (DTU-100) 1406-( ) Any This STC requires that existing DTU is interfaced with one or more compatible Universal Avionics UNS-1( ) Flight Management Systems (FMS) on each airplane eligible for this proposed modification. The equipment must be properly interfaced to meet the intended function for the system, as certified under this AML approval. The Universal Avionics SSDTU is compatible with only Universal Avionics products as defined in the Universal Avionics Installation Manuals and Installation Instructions listed on the MDL. Interface to devices from other manufactures, including commercial off-the-shelf (COTS) devices, is not supported by the SSDTU or by this STC. Certification Basis Based on 14 CFR §§ 21.115 and 21.101, and FAA order 8110.48, the type certification basis for the aircraft models listed in the attached Approved Model List (AML) for the I nstallation of Solid State Data Transfer Unit (SSDTU), P/N 1408-( ),operating software SCN 10.X, was determined to be: Regulations at the latest amendment 23-0 through 23-49 23.1301; 23.1309(a),(b),(e); 23.1351(a); 23.1431(a), (b); 23.1529 Regulations at an intermediate amendment None Regulation at the amendment level in TCDS’ None If the holder agrees to permit another person to use this certificate to alter the product, the holder shall give the other person written evidence of that permission. ### SA02347LA AML.pdf This is OCR from the scanned FAA attachment.
