Owners had to complete this within 100 hours of flying time after July 1985.\n\n**Why it's cancelled:** The Civil Aviation Safety Authority (CASA) cancelled this rule on 3 July 2008 because all affected aircraft had already been modified. Once every plane has complied, the safety rule is no longer needed.\n\n**Who it affects:** Owners and operators of Piper PA-28 series aeroplanes.
