AD NUMBER: 2006-24-05
SUBJECT: Airworthiness Directive 2006-24-05 SUMMARY: The FAA is
adopting a new airworthiness directive (AD) for certain Boeing
Model 747 airplanes.
This AD requires repetitive inspections for any cracking of the
fuselage skin in section 41 of the airplane, and related
investigative and corrective actions if necessary.
This AD results from a report of fatigue cracks found in the
skin in section 41 of the fuselage, on an in-service Model 747
We are issuing this AD to detect and correct fatigue cracks at
the fastener rows of the fuselage skin in section 41, which could
join together and cause a loss of structural integrity and rapid
decompression of the airplane.
