AD/F27/88 - Emergency Light - Modification - CANCELLED

What this does: This document officially cancels a 1976 safety rule (Airworthiness Directive) that required Fokker F27 aircraft to install special emergency lights capable of operating under high gravity forces (2.2g).

Who it affects: Owners and operators of Fokker F27 series aircraft. Given the long compliance history, this primarily affects historical maintenance records rather than current operations.

Why it matters: The original rule required compliance by March 1977. By 2009—over 30 years later—the Civil Aviation Safety Authority determined that all affected aircraft should have been modified long ago, making the rule redundant. This cancellation tidies up the regulatory framework by removing a requirement that has already been universally implemented.
