Does Special Airworthiness Information Bulletin HQ-16-14 (March, 2016) resolve this life limit issue? Was the life limit in the original type certificate or was it added later?

Paul, et al,
You might try speaking with Brian Collins of Eastern Soaring Center, https://www.easternsoaringcenter.com/
based at W99, Petersburg, WV. He runs a winch operation there and trains using a Twin Lark. A group of us were there a few weeks ago working on our winch endorsements, so I know his ship is active and airworthy.
