## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

An inspection of a PZL-104 aeroplane that had a relatively long operational background revealed a severe corrosion of the steel front fuselage structural elements. It is likely that such corrosion can also be present on other aeroplanes of similar design and operational history. If left uncorrected, this condition could lead to loss of strength of the structural front posts elements and consequent reduction of the structural strength of the aeroplane.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
