Plain English Summary

1/10 complexity

This document cancels a previous aircraft safety rule (Airworthiness Directive AD/B737/31) that applied to Boeing 737 aeroplanes.

What it did previously: The old rule required specific inspections or repairs to the fuselage (the main body of the plane), particularly the lower skin at a structural point called "Stringer 14" on both sides of the aircraft.

What happens now: As of 6 July 2006, airlines and aircraft operators no longer need to follow that specific rule. Instead, they must comply with a newer replacement directive (AD/B737/281), which supersedes this one.

Who is affected: Anyone operating Boeing 737 series aircraft in Australia (airlines, charter companies, maintenance organisations).

Why it matters: This is an administrative clean-up. It removes outdated maintenance requirements to avoid confusion, ensuring operators follow only the current safety standards rather than overlapping or obsolete rules.
