Progress on OPS3-517 Modification: Ensuring Acceptable Operations with Exposure

This document outlines the substantial efforts made over the past three years to modify JAR OPS3-517 to ensure operations with exposure are compliant and acceptable to authorities, operators, and manufacturers. Key modifications have been achieved to facilitate agreement among stakeholders during meetings, notably in Las Vegas (02/2004). The deadline of March 31, 2005, for operations under modified OPS3-517 is approaching, creating a high risk of blocking due to NPA38 not being officially included in the rule. The proposal includes recognizing NPA38 as a valid alternative and seeking to extend the deadline.

  1. JAR OPS3 NPA 38Performance Class 2 with exposure

  2. JAR OPS3-517 status of the modification process • Since three years a lot of work has been performed within HSC to modify OPS3-517 in order to make demonstration work for operations with exposure acceptable by Authorities, Operators and Manufacturers. • Through NPA 38 OPS3-517 and associated Appendix and AMJ has been deeply modified in order to reach an HSC agreement (agreement achieved in Las Vegas meeting 02/2004)

  3. JAR OPS3-517 (b) : alleviation to 3-517(a) • After 31 March 2005 operations with exposure under 3-517 (b)(at amendment 3) (alleviation to 3-517(a)) will no more be authorized. • Nevertheless the reason why the modification process of OPS3-517 was engaged three years ago (see previous slide) remains. • There is a high risk of blocking, due to the fact that NPA38 is not already transfered in the rule • Proposal to come out of this dead end: • 1/ Use NPA38: • as an equivalent safety to OPS3-517 (at amendment 3), should be acceptable by all the parties because it is the result of an internal HSC agreement, • give NPA38 an “official existence” (by putting it on OST agenda very very soon ?) • 2/ Postponed 31 March 2005 deadline • Note: first proposal will give enough “official” existence to NPA 38 to guarantee that it will be taken into-account by EASA in the writing process of OPS IR
