Airworthiness Directive 00-19670

AD 00-19670 · 2000-08-07 · airframe

Airworthiness Directives; Boeing Model 747-100, -200, -300, 747SR, and 747SP Series Airplanes

What this AD requires

This document corrects information in an existing airworthiness directive (AD) that applies to certain Boeing Model 747- 100, -200, -300, 747SR, and 747SP series airplanes. That AD currently requires repetitive inspections to detect cracking of the longeron splice fittings at stringer 11, on the left and right sides at body station 2598, and replacement of any cracked fitting with a new fitting. This document clarifies the applicable compliance time for certain airplanes. This correction is necessary to ensure that fatigue cracking on longeron splice fittings, which could result in reduced controllability of the horizontal stabilizer, is detected and corrected in a timely manner.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 00-19670 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 00-19670 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
