As noted in the National Transportation Safety Board’s May 3 investigative update of the engine failure on Southwest Airlines flight 1380, CFM International issued Service Bulletin 72-1033 on April 20 recommending ultrasonic inspections of fan blades of CFM56-7B engines with more than 30,000 cycles. The Boeing 737 on flight 1380 was powered by engines from CFM International, which is a joint company between GE Aviation and Safran Aircraft Engines.
By the end of August, CFM International also recommends inspections for fan blades with 20,000 cycles. When other fan blades reach 20,000 cycles, they also should be inspected, according to the service bulletin. After the first inspection, it is recommended that inspections are repeated every 3,000 cycles (typically, about two years in airline service).
Glycerol Echo Lot 205 from Echo Ultrasonics has been approved by GE Aviation for this inspection work.
