AD 2013-19-20 Airworthiness Directives; The Boeing Company Airplanes
Models named: DC-10-10, MD-10-10F. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company Model DC-10-10 and MD-10-10F airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin DC10-32A260, dated September 30, 2011.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For airplanes having any bolts identified in paragraph 3.B.1. of the Accomplishment Instructions of Boeing Alert Service Bulletin DC10-32A260, dated September 30, 2011: Before the accumulation of 6,590 total flight cycles on the bolt, or within 180 days after the effective date of this AD, whichever occurs later, replace the MLG upper torque link bolt with a new or serviceable bolt, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin DC10-32A260, dated September 30, 2011. A review of airplane maintenance records is acceptable if the part number of the bolt can be conclusively determined from that review. Thereafter, before the accumulation of 6,590 total flight cycles on any bolt identified in paragraph 3.B.1. of the Accomplishment Instructions of Boeing Alert Service Bulletin DC10-32A260, dated September 30, 2011, replace it with a new or serviceable bolt.
Unsafe condition
This AD was prompted a report that the safe life limit on certain main landing gear (MLG) upper torque link bolts is reduced significantly due to those bolts being fabricated from bar stock with a machined head. We are issuing this AD to prevent damage to the MLG and consequent damage to airplane structure, which could adversely affect the airplane's continued safe flight and landing.
Affected ADs
None.
