I have a friend looking at rebuilding an IS-29 lark.

Are parts available? Does it have a life limit like the 28?

Thanks,

Not sure if parts are available (though Blanik parts may fit in some
cases) but it definitely has a life limit, and a factory approved
inspection method for life extension.

really? i found a pdf of the flight and maintenance manual online as
well as the faa type certificate and didn't see anything about a life
limit. *there are no AD's against the IS-29 that I can find in the FAA
database.

I looked at the TCDS for both the -28 and -29 and neither mentioned
life limits. I found a POH for the single seat Lark and it did not
mention life limits.

i've never been able to find definitive documentation (besides RAS
posts) online proving that life limits exist in the USA. Although my
CFIG owned a IS28B2 Lark when I was training and did a life extension
on it so I assume it is in fact somehow required.

There was a 2 seat Lark in the club when I first joined. I remember a
30yr calendar life limit that was extended with factory approved
inspection and replacement of some life limit (time) parts like
control pushrods.
