AD NUMBER: 2010-01-10
MANUFACTURER: The Boeing Company Model 747-100,
747- 100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300,
747SR, and 747SP Series Airplanes Equipped With General Electric
CF6-45 or -50 Series Engines, or Equipped With Pratt & Whitney
JT9D-3 or -7 (Excluding -70) Series Engines
SUBJECT: Airworthiness Directive 2010-01-10
SUMMARY: The FAA is superseding an existing
airworthiness directive (AD), which applies to certain Model
747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F,
747-300, 747SR, and 747SP series airplanes. That AD currently
requires repetitive inspections to detect cracks and fractures of
the strut front spar chord assembly (including the forward side) at
each strut location, and repair if necessary. This new AD adds a
one-time inspection for cracking of the forward side of the front
spar chord assembly on the inboard and outboard struts,
installation of a cap skin doubler for certain airplanes, and
repair if necessary. These actions terminate the repetitive
inspections of the forward side of the strut front spar chord
assembly; the inspections of the aft side assembly continue as
specified in the existing AD. This AD results from a report of a
fractured front spar assembly for strut No. 3, which resulted in
the loss of the strut upper link load path. We are issuing this AD
to detect and correct cracks and fractures of the nacelle strut
front spar chord assembly. Fracture of the front spar chord
assembly could lead to loss of the strut upper link load path and
consequent fracture of the diagonal brace, which could result in
in- flight separation of the strut and engine from the
airplane.
