#### SUBPART B – LIST OF ETSOs *ED Decision 2022/018/R* This Subpart contains two Indexes: **1 INDEX 1** 1.1 Index 1 lists all those ETSOs which are technically similar to FAA-TSOs. 1.2 When an article has been approved by the Agency to an ETSO listed in Index 1 the article is to be permanently marked with the appropriate ETSO number. Also, all documentation associated with Certification and Release for installation on an aircraft must record this ETSO number. The ‘E’ Symbol signifies that the article has been certified to the relevant ETSO by the Agency. 1.3 Index 1 lists all those ETSOs whose functional requirements are equivalent to those of the corresponding FAA TSOs that have the same identification numbers. 1.4 Reserved 1.5 The ETSO numbering system is explained as follows: — ETSO-C5e means: European TSO-Number and revision letter, and so — ETSO-C95 with no revision letter means initial issue. NOTE: Copies of ETSOs are listed in Index 1. **2 INDEX 2** 2.1 Index 2 lists all those ETSOs which are not technically similar to the FAA-TSOs. Index 2 ETSOs are identified by ‘2C’ prefixes, and numbered as follows: (a) An ETSO with significant differences in the MOPS in comparison with the corresponding FAA TSO is identified by the same number as the corresponding FAA TSO (related to the same type of equipment) with a number in the range from ETSO-2C1 to ETSO-2C499; or (b) An ETSO for which there is no corresponding FAA TSO (related to the same type of equipment) is identified by a number in sequence from ETSO-2C500 upwards. **Index 1** <table bgcolor="#d9d9d9" cellpadding="7" cellspacing="0"> <col/> <col/> <col/> <tr
