AD NUMBER: 2007-12-11
MANUFACTURER: Boeing
SUBJECT: Airworthiness Directive 2007-12-11
SUMMARY: The FAA is superseding an existing
airworthiness directive (AD), which applies to certain Boeing Model
747 airplanes. That AD currently requires repetitive inspections to
detect cracks and/or corrosion of the girt bar support fitting at
certain main entry doors (MED), and repair or replacement of the
support fitting. The existing AD also provides for various
terminating actions for the repetitive inspections. This new AD
requires the following additional actions: An inspection, for
certain airplanes, for correct installation of square and conical
washers in the girt bar support fitting; an inspection, for certain
other airplanes, to determine if the washers are installed; and
related investigative and corrective action if necessary. This AD
results from a report that the square and conical washers may be
installed incorrectly in the girt bar support fitting on airplanes
on which the support fitting was repaired or replaced in accordance
with the requirements of the existing AD. We are issuing this AD to
detect and correct corrosion of the girt bar support fitting, which
could result in separation of the escape slide from the lower door
sill during deployment, and subsequently prevent proper operation
of the escape slides at the main entry doors during an emergency.
We are also issuing this AD to detect and correct incorrect
installation of the square and conical washers in the girt bar
support fitting, which could result in failure of the escape slide
when deployed.
