AD/PA-28/31 - Seat Frame - Modification - CANCELLED

This document cancels an obsolete aviation safety rule that is no longer needed.

In 1971, the Civil Aviation Safety Authority required owners of Piper PA-28 aircraft to modify the pilot and co-pilot seat frames to fix a safety defect. Nearly 40 years later, CASA has cancelled this directive because every affected aircraft would have completed the modification decades ago.

What this means:

• The seat frame modification requirement no longer applies to these aircraft
• Owners no longer need to maintain specific compliance records for this rule
• The cancellation takes effect on 3 July 2008

This is essentially housekeeping to remove redundant rules from the aviation safety regulations.
