Airworthiness Directive 2013-02-07
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by reports from the manufacturer that center overhead stowage (COS) boxes could fall from their supports under forward load levels less than the 9 g forward load requirements as defined by certain regulations. This AD requires modifying COS boxes by installing new brackets, stiffeners, and hardware as needed. We are issuing this AD to prevent detachment of COS boxes at forward load levels less than 9 g during an emergency landing, which would cause injury to passengers and/or crew, and could impede subsequent rapid evacuation.
Which aircraft AD 2013-02-07 applies to
Applicability limited to airplanes identified in Boeing Special Attention Service Bulletin 737-25-1641, Revision 1, dated August 8, 2011, as revised by Revision 2, dated November 20, 2012.
Whether AD 2013-02-07 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
