Plain English Summary

1/10 complexity

What this does: This is a mandatory safety order (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority (CASA) requiring owners and operators of specific Piper aircraft to modify certain passenger seats.

Who it affects: Anyone who owns or operates Piper PA-31 series aircraft that have rear-facing seats installed in the forward cabin position—unless those seats have already been modified according to the manufacturer's Service Bulletin No. 308.

What must be done: The rear-facing seats must be modified exactly as specified in Piper Service Bulletin No. 308. This isn't optional—failure to comply violates civil aviation safety regulations and the aircraft cannot be operated legally without this modification.

Why it matters: These modifications address specific safety defects in the original seat design (likely relating to structural integrity or restraint systems during turbulence or impact). Airworthiness Directives are issued only when unsafe conditions exist that could affect flight safety.
