Agenda Item No. 4 Specified Data WHAT IS IT? • Specified Data is a “source” description. Per AWM 571.06: “is information contained in authoritative documents which, although not approved by the Minister, has been specified by the Minister as appropriate for the purpose of major modifications and major repairs…” • In contrast, “approved data” is a “content” document , created and approved specifically for the modification or repair 1 WHAT IS SPECIFIED DATA? Specified data includes: (a) drawings or methods described or referenced in Airworthiness Directives; (b) data issued by the manufacturer or type certificate holder of the aircraft, component or appliance, such as modification orders, service bulletins, or engineering orders, which include a statement of approval by the applicable regulatory authority or a delegated representative of such an authority. Where the data issued by the aircraft manufacturer are incompatible with those of the component or appliance manufacturer, the data of the aircraft manufacturer shall prevail; (c) manufacturer’s Structural Repair Manuals; (d) FAA Advisory Circulars AC 43.13-1 and AC 43.13-2, subject to specific conditions. 2 SPECIFIED DATA - Use of AC 43.13 • FAA Advisory Circulars AC 43.13-1 and AC 43.13-2, subject to the following conditions: (i) the aircraft is a small aircraft, and the alteration does not affect dynamic components, rotor blades, structure that is subject to pressurization loads, or the primary structure of a rotorcraft; (ii) the alteration does not affect an existing limitation (including the information contained on mandatory placards) or change any data contained in the approved sections of the Aircraft Flight Manual, or equivalent; (iii) the data are appropriate to the product being altered, and are directly applicable to the alteration being made; and, (iv) the data are not contrary to the aircraft manufacturer’s data. 3 SPECIFIED DATA- RECENT CHANGES Recent NPAs to 571.06 approved at CARAC in 2000 introduced changes: • to clarify use of AC 43-13, as well as • to introduce explicitly that Minister could “specify” data • To place data associated with ADs in “approved data” category 4 SPECIFIED DATA - The Intent • It was intended to specify “source” documents that contained information necessary to satisfy airworthiness design requirements for specific installations. • Data specified must be complete enough to assure that the requirements of the certification basis are met if the modification / repair is accomplished i.a.w. the specified data • No additional data should be required • No assessment of compliance should be required by the installer as the data is supposed to be complete. 5 SPECIFIED DATA - Issues • Use of specified data has evolved over years, but applications and scope have not been well documented and limited guidance material has been • Variations in usage between regions has caused standardization issues • Industry has requested ability to expand use of specified data 6 TCCA Position on Specified Data • Use of specified data to be re-aligned to original intent • Use will be limited to: List provided in current 571.06(1) definition. (list is exhaustive) Material specified by the Minister • will only be published ACSIs / ACPLs addressing specific types of installations • existing example: ACPl 60 Encoding Altimeters • proposed future: GPS (ACPL 17 revision) other simple avionics (VHF, Nav/Com) 7 SPECIFIED DATA – Proposed Model Existing List in 571.06 - OEM SBs - SRM - AC 43-13 with conditions Guidance Material “specified” by the Minister i.e. ACPL 60 - GPS (based on ACPL 17) OR - CVR - Simple Avionics (I.e. VHF/VOR/NAV COM) - Other topic specific as developed and specified by TCCA 8
