AD/BEECH 33/11 - Front Seat Restraint Installation - CANCELLED

What this is: A cancellation of an old aircraft safety rule.

What it does: This document officially ends Airworthiness Directive (AD) BEECH 33/11, a 1971 rule that required shoulder harnesses (upper torso restraints) to be installed in the front seats of certain Beechcraft aircraft models (the 33 and 35-33 series, also known as Debonair or Bonanza).

Who it affects: Operators of these specific Beechcraft models. However, the original rule required compliance by 1972, so most aircraft would have been modified decades ago.

Why it matters: The Civil Aviation Safety Authority cancelled this directive because it became obsolete. Once the long-ago compliance deadline passed and the safety modifications were made, keeping the rule on the books served no further purpose.
