This Directive requires operators of specified Boeing 747 series aeroplanes to inspect and, if necessary, replace H‑11 bolts at the wing rear spar lower chord splice plate and kick fittings to prevent stress‑corrosion cracking. It implements the technical requirements of FAA AD 2000-08-14, imposes recurring inspection and replacement obligations, and therefore creates operational and financial compliance duties for the affected owners/operators.
