Airworthiness Directive 2014-13-07
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 737-300, -400, -500, -600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a review of the tail strobe light installation, which revealed that the tail strobe light is not electrically bonded to primary structure of the airplane. This AD requires installing a new tail strobe light housing and a new disconnect bracket, and changing the wire bundles. This AD also requires, for certain airplanes, an inspection to determine if sealant is applied, and corrective actions if necessary. We are issuing this AD to prevent, in case of a direct lightning strike to the tail strobe light, damage to the operation of other critical airplane systems due to electromagnetic coupling and large transient voltages, and damage to the control mechanisms or surfaces due to a fire, which could result in loss of control of the airplane.
Which aircraft AD 2014-13-07 applies to
Applies to airplanes identified in Boeing Special Attention Service Bulletin 737-33-1149 (dated April 13, 2012, for -300/-400/-500) and 737-33-1146 Revision 1 (dated July 9, 2013, for -600/-700/-700C/-800/-900/-900ER). Installation of STC ST00830SE does not affect ability to accomplish the required actions; a 'change in product' AMOC is not necessary for airplanes with that STC installed.
Whether AD 2014-13-07 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.
