Boeing 737s undergo another round of airworthiness checks

 
   

Following a round of emergency checkups in March, the US Aviation safety watchdog has now issued a brand new airworthiness directive for all operators of narrow-body Boeing 737s to double-check their aircraft.

The US Federal Aviation Administration (FAA) checkups relate to the a bearing found on the plane’s side elevators, which help control the plane’s pitch, and when loose can lead to severe vibrations.

This recent airworthiness directive issued on Monday was announced after an aircraft experienced the severe vibrations despite having conducted the checkup when it was mandated earlier in March.

“On March 18, 2010, we issued AD [airworthiness directive] 2010-06-51… Since we issued that AD, we received an additional report of failure of the aft attach lugs on the left elevator tab control mechanism,” said the FAA in its new airworthiness directive.

“We have determined that an improved inspection is necessary to address the identified unsafe condition.”

FAA’s directive for inspection of the inboard and outboard aft attach lugs of the left and right elevator control tab mechanisms is valid across the entire Boeing 737 family including the -600, -700, -800, and -900.
