PA-31 Wing Leading Edge Stall Strip Configuration SIB 2010-09

The Civil Aviation Safety Authority (CASA) of Australia has
published the referenced advisory document (attached as pages 2
through 4 of this bulletin) to draw the attention of owners, operators
and maintainers of Piper PA-31 series aeroplanes to the existing
wing leading edge stall strip (or flow strip) configuration
requirements.
After reviewing the available information and recognising that
CASA is not the ‘State of Design’ authority for the affected type
design, EASA concurs with the advisory and fully supports the
CASA recommendations contained therein. This SIB is published
to ensure that all owners, operators and maintainers of the affected
aeroplanes, registered in European Union Member States or
associated countries, are aware of these recommendations.
