AD/AC/47 - Front Seat Restraint Installation - Modification - CANCELLED

This document officially cancels a 1972 aviation safety rule that required shoulder harnesses (seatbelts that go over the shoulders and chest) to be installed in the front seats of certain older Twin Commander aircraft.

What the original rule did: It required owners of Twin Commander 500, 600, and 700 series aircraft—specifically those certified before 1967—to install upper torso restraints to protect pilots and front-seat passengers during crashes.

What this document does: As of 17 January 2008, this specific rule is cancelled and no longer applies. The safety requirements have moved to a broader rule (AD/GENERAL/74 Amendment 1) that covers similar protections across multiple aircraft types, rather than just these specific Twin Commander models.

Who needs to know: Owners and operators of the affected Twin Commander aircraft should follow the replacement general directive instead of this cancelled one.
