The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2018-19-23. Comply with the one in force.
This AD applies to The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 747-52-2286, Revision 1, dated October 28, 2010; and Model 757-200, -200PF, and -300 series airplanes, certificated in any category, as indentified in Boeing Special Attention Service Bulletin 757-52-0090, dated September 21, 2007.
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes; and certain Model 757-200, -200PF, and -300 series airplanes. That AD currently requires replacing the control switches of the forward, aft, and nose cargo doors of Model 747 airplanes; and requires replacing the control switches of cargo doors 1 and 2 of Model 757 series airplanes. This new AD adds airplanes to the applicability and revises the initial compliance times for those airplanes. This AD was prompted by reports of problems associated with the uncommanded operation of cargo doors. We are issuing this AD to prevent injuries to persons and damage to the airplane and equipment.
This paragraph restates the requirements of paragraph (f) of AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009), with revised compliance times and service information. Replace the control switches, as specified in paragraph (g)(1) or (g)(2) of this AD, as applicable. Repeat the replacements thereafter at intervals not to exceed 72 months.
(1) For Groups 1 and 2 Model 747 airplanes identified in Boeing Special Attention Service Bulletin 747-52-2286, Revision 1, dated October 28, 2010: Within 24 months after December 3, 2009 (the effective date of AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009)), or within 72 months from the date of issuance of the original certificate of airworthiness or the original export certificate of airworthiness, whichever occurs later, replace the control switches of the forward, aft, and nose cargo doors, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 747-52-2286, dated September 28, 2007; or Boeing Special Attention Service Bulletin 747-52-2286, Revision 1, dated October 28, 2010. As of the effective date of this AD, use only Boeing Special Attention Service Bulletin 747-52-2286, Revision 1, dated October 28, 2010, to do the actions specified in this paragraph.
(2) For Model 757 series airplanes: Within 24 months after December 3, 2009 (the effective date of AD 2009-22-08, Amendment 39-16059 (74 FR 55763, October 29, 2009)), replace the control switches of cargo doors 1 and 2, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 757-52-0090, dated September 21, 2007.
