Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
This paragraph restates the requirements of paragraph (g) of AD 2012-05-03, with revised service information. Within 60 months after April 24, 2012 (the effective date of AD 2012-05-03), modify the fluid drain path in the leading edge area of the wing, in accordance with all applicable parts of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 747-57-2332, Revision 1, dated July 25, 2011; or Revision 2, dated February 22, 2016.
Unsafe condition
This AD was prompted by a design review following a ground fire incident and reports of flammable fluid leaks from the wing leading edge area onto the engine exhaust area. We are issuing this AD to prevent flammable fluid from leaking onto the engine exhaust nozzle, which could result in a fire.
Affected ADs
This AD replaces AD 2012-05-03, Amendment 39-16975 (77 FR 16143, March 20, 2012) (“AD 2012-05-03”).
