AD/PA-28/33 - Front Seat Restraint Installation - Modification - CANCELLED

What this is: A cancelled Airworthiness Directive (AD) — a mandatory safety rule that once applied to specific aircraft.

What it used to do: Originally issued in 1971, this rule required owners of Piper PA-28 aircraft (light, single-engine planes) to install upper torso restraints (shoulder harnesses) in the front seats if their plane was certified before 1967.

What it does now: Nothing. This directive was officially cancelled on 17 January 2008.

Why it matters: If you own or operate a Piper PA-28, you no longer need to check this specific rule. The old requirement has been replaced by a newer, broader safety rule (AD/GENERAL/74 Amendment 1) that applies to multiple aircraft types. You should check that newer directive instead to see what restraint requirements currently apply to your aircraft.
