3-point belts in vintage Mooney under EASA

[MV Aviation]

Hi folks,

has anyone with an EASA-reg vintage Mooney (A-G) upgraded their aircraft with 3-point seat belts? There is a FAA STC by Alpha Aviation But nothing else. 
If you have a shoulder harness, where did you get it and what is the legal base for its installation?

The CS-SC153b only allows the replacement of existing belts, but no upgrade or new installation.

Thanks!

@MV Aviation - see if you can perhaps leverage the EASA validation of FAA Supplemental Type Certificate classified as Basic and limited to one serial number - I seem to recall it didn't cost an absurd amount of money when I looked at it.

my front seat shoulder harnesses were validated by the Danish CAA a while back and you should be able to grandfather that. Drop me your email and I ll scan what I have.

I did upgrade my M20F with with 3-point seat belts by Alpha  Aviation.

Mooney Service Center in Germany did all the job.

I'm very satisfied.

Hi Andrea, can you elaborate a bit on the paperwork? What is the legal base for the install?
The vintage Mooneys did not feature 3-point belts from factory, so it's hard to argue that it's only a replacement. Hence, one needs an STC (which does not exist for EASA aircraft to my knowledge) or minor/major change paperwork.
Thanks for your help!
