IS-28B2 Twin Lark - Service Life Extension Program

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.

Paul, the answer is yes, it does, so long as your Twin Lark (serial number) was sold to you with an original (or subsequent) POH that has no lifetime limitation. Speak to your local FSDO if you want independent confirmation.

Sandhill Soaring Club has a Twin Lark for sale, which does not have a lifetime limitation. The aircraft was flying and them mothballed. We learned of the bulletin less than 6 months ago and did our homework on the matter. If you're interested in buying a ship that can be easily returned to service, please email me directly. Thanks.

Hello,

My father recently passed away and owned a 40 year old Lark Two Place Sailplane Model 1S28B2. It is in desperate need of repair and also the lifetime limitation has expired and cannot be flown. It has been tied down for many years. I believe the repairs will cost at least $12,000-14,000. Does anyone know the refurbished value of the plane? Trying to figure out what to do with it. Sounds like the out of use for life is now in place. I honestly don't know anything about this, so any help would be much appreciated.

Thanks, Birgit Byers

Twin Lark for Sale! It was mothballed several years ago and stored in our hangar. It can easily be brought back into service. Original POH. No mention of a Lifetime Limitation in the POH. Will be sold "as is." Our club is consolidating its fleet and is a motivated seller. Please email me directly.

Our club owns an I.C.A.-BRASOV IS-28B2 Twin Lark which is grounded because it has exceeded its 35 year factory maintenance program service life. About a year ago the current type certificate holder, S.C. Constructii Aeronautice S.A., announced it intended to submit a Service Life Extension Program (SLEP) to EASA - with follow-on submission to the FAA. We are no longer able to reach S.C. Constructii Aeronautice S.A. by phone - and they do not respond to emails. Can anyone shed any light on the status of the SLEP or offer any contact information for S.C. Constructii Aeronautice S.A.? We enjoy this ship and would like to return it to service.
