WASHINGTON (CN) – The Federal Aviation Administration has issued Airworthiness Directives for airplane operators to correct unsafe conditions that may lead to a lack of structural integrity of their planes.
Among them, certain Airbus A340 airplanes must be inspected for fuselage fatigue cracking, and the McDonnell Douglas MD-90-30 must be checked for cracking at the wings.
The FAA plans to require more frequent inspections for certain modified Boeing 747s that may have fatigue cracking in the lower part of the fuselage, and France’s aviation authority has informed the FAA that certain Empresa Brasileira de Aeronautica S.A. models must have more stress applied for fatigue tests, so appropriate measures may be taken before a crack affects the structural integrity of the plane.
Additionally, certain Airbus A300 airplanes may develop cracks above the nose landing gear, Airbus model A340-200 and A340-300 series airplanes could lose an engine due to structural fatigue.
