EASA / Installation approval requirements
Since 8 July 2015 many installations may be done without involving, EASA and national aviation authorities (NAA). This means that we are able to do installations in a more efficient way – but most important is that we no longer need to wait for modification approvals which previously has caused several months delay. The EASA minor change fee of 300 Euro may be invested in equippment instead.
Please understand that proper paper work and engineering orders including all aspects of the installation are still required. The working hours for developing such still remain and will require a skilled engineer with proper knowledge of Part-M, Part-145, Part-21, CS-23 (GA aircraft), CS-27 (light helicopters), AMC-20 and a whole library of other equippment manufacturers and requlatory publications.
NAA / Annex II aircraft
1- EASA CS-STAN procedures are now also acceptable for Swedish Annex II aircraft! Swedish registered Annex II aircraft will in many cases no longer need a national minor change approval. Instead CAA Sweden will accept EASA CS-STAN procedures. Futher details, validity and possible limitations – refer to CAA Sweden MFL AIR 2017-3. Link
2. Aircraft not included in pos 1 above will require an approval issued by the NAA and for aircraft registered in Sweden the engineering paper work and application is sent to and inspected/approved by CAA Sweden. Refer to CAA Sweden regulation TSFS 2012:87
2. An existing modification approval. A complete list of all approved modifications is found in the document:
“TU Transportstyrelsens sammanställning över godkända luftfartyg, modifieringar, utrustningar m.m.”
(Note that this document has not been updated in a while)
EASA Aeroplanes and helicopters
1. EASA standard repairs and changes in accordance with CS-STAN (no EASA application required)
2. EASA minor change – for repairs and changes not includes in CS-STAN (medium complex installations)
3. EASA STC – for repairs and changes not applicable to any category 1 or 2 above (complex installations)
4. Validated FAA STC. Pay attention – validated FAA STC’s may be revised by FAA and these changes may me automatically approved by EASA in accordance with bilaterad agreements – Decision 2004/04/CF.
5. Grandfathered national modification approval.
