PETALING JAYA: Malaysian-based airlines operating the Boeing 737-8 MAX have been given until Jan 10 to check the aircraft’s rudder control systems for loose connectors.
The Civil Aviation Authority of Malaysia (CAAM) ordered operators to inspect the rudder control system for a rogue nut as listed in an advisory from the aircraft manufacturer, Boeing.
CAAM chief executive Norazman Mahmud said the Boeing notice said an international operator had detected a bolt with a missing nut in the rudder-control linkage of the aircraft.
He said Boeing also inspected several of its aircraft in production and found an additional aft rudder quadrant output rod with an under-torqued (hand tight) fastener.
“The fastener plays a significant role in ensuring proper functioning of the rudder control system.
“A disconnect between the aft quadrant output rod and the rudder feel and centring unit will result in the loss of positive feel and centring in the pilots’ rudder pedals,” Norazman said in the note sighted by FMT.
He advised the local operators to plan and schedule their 737-8 MAX fleet for the inspection as recommended by the manufacturer.
“They should report the inspection findings to the CAAM via the organisation’s assigned primary inspector and also its aviation reporting system.
“Notification should also be made to Boeing,” Norazman said.
He added that CAAM will closely monitor the situation and determine if additional action is required as new information becomes available.
