A couple of days ago EASA released a new document outlining a long list of "Standard Changes" - changes that can be made to certificated GA aircraft without the need for an STC. The list includes some rather amazing things: - COM Radios - NAV Radios - Moving map displays - Audio panels - Lighting - ELTs The gear still has to be approved by TSO or equivalent, but there is no type-specific approval required. Here's a write up by AIN: https://www.ainonline.com/aviation-...ama-praises-easas-streamlined-process-repairs Here's the actual EASA document: http://easa.europa.eu/system/files/dfu/Annex IV to EDD 2015-016-R.pdf This is a big (first) step. They still require a mechanic to return the aircraft to service - even for lightbulb changes - but it heading in the right direction. Hopefully the next thing to happen will be a new means of approval based on a recently completed ASTM standard that replaces the expensive verification processes referenced by the TSOs with a much simpler pragmatic testing regimen. This could open the door to approval of systems currently sold into the Experimental and Light Sport markets - a huge step forward for GA modernization.
