This Opinion addresses efficiency/proportionality as well safety issues related to Annex IV (Part-MED) to Commission Regulation (EU) No 1178/2011. As both rulemaking tasks (RMTs), RMT.0287 and RMT.0700, amend the provisions prescribed in Part-MED, EASA decided to merge the outcome of the respective consultations and publish one Opinion on the update of Part-MED to prevent any inconsistencies that may emerge during the rulemaking process.
