inspections of Boeing 737 MAX model

In response
to recent findings, the Federal Aviation Administration (FAA) is intensively
monitoring targeted inspections of Boeing 737 MAX airplanes, specifically
focusing on the rudder control system. The objective is to identify any
potential issues related to a loose bolt within this critical component.
Working in
close collaboration with the FAA, Boeing has issued a Multi-Operator Message
(MOM), directing operators of newer single-aisle airplanes to conduct
inspections on specific tie rods responsible for controlling rudder movement.
The emphasis is on scrutinizing the hardware for any signs of looseness or irregularities.
The FAA is
maintaining continuous communication with both Boeing and the affected airlines
throughout the inspection process. As part of this coordinated effort, the
agency has urged airlines to leverage their approved Safety Management Systems to
assess whether any instances of loose hardware have been previously detected.
Additionally, the FAA is requesting detailed information on the timeframe
within which the prescribed two-hour inspections can be completed.
Depending on
the outcomes of these inspections, the FAA stands ready to take further
actions. Any discovery of loose or missing hardware may prompt additional
measures to ensure the safety and reliability of the Boeing 737 MAX fleet.
The impetus
for these inspections stems from a recommendation by Boeing, following the
discovery of a missing nut on a bolt during routine maintenance by an
international operator. Subsequent investigations revealed a similar issue on
another undelivered aircraft, where a nut was found to be improperly tightened
in the rudder-control linkage.
