This AD was prompted by the determination that insufficient sealing may allow water to enter the lower lobe electronic equipment (EE) bay through the main deck floor structure at the rigid cargo barrier (RCB), which could cause damage to EE bay line replacement units (LRUs) in the E5 rack. The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-800 series airplanes.

The FAA is issuing this AD to address the unsafe condition on these products. This AD also limits the installation of affected parts under certain conditions. This AD requires modifying the rudder pedal cover and shroud assemblies, and applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and - 900ER series airplanes and Model 737-8 and 737-9 airplanes. This AD was prompted by a report of an aborted takeoff because the rudder pedals were not operating correctly, and subsequent reports of loose rudder pedal cover fasteners on airplanes on which the actions required by AD were done and on additional airplanes that were not included in the applicability of AD. AD required a torque check of the screws in the cover assembly of the heel rest for both the captain's and the first officer's rudder pedals, and corrective action if necessary. The FAA is superseding Airworthiness Directive (AD), which applied to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD requires a detailed inspection of a certain body station bulkhead, between certain stringers, for any incorrectly installed fastener common to fuselage skin, and applicable on-condition actions. This AD was prompted by reports of incorrectly installed fuselage skin fasteners.
