PA31 Spar

[Bang Bus]

Hello,
Just chasining some info from those in the know with regard to spar life. Wondering as to common types in Oz that have a spar life, and how many hours that life may be.

Thanks Bang

The lower wing spar on a chieftain has around 13000 hours from memory. After 2 lives the rest of the Airframe has to be retired. Refer to CASA AD PA31/37 for applicability to other models in the PA 31 series.

while on the topic any idea of the time or dollars required for that AD?
