The NTSB's preliminary report on UPS Flight 2976 indicates fatigue cracking within the left engine pylon structure is a key focus of its investigation.
The MD-11F crashed shortly after takeoff, with surveillance video showing the No. 1 engine and pylon separating from the wing, resulting in a fire and the deaths of 14 people.
Investigators found evidence of fatigue cracks on multiple fracture surfaces of the left pylon's aft-mount lugs and a circumferential fracture of the spherical bearing.
Following the incident, UPS grounded its MD-11 fleet, and the FAA issued emergency airworthiness directives for MD-11 and DC-10 models, referencing the similar 1979 American Airlines Flight 191 crash.
The National Transportation Safety Board says fatigue cracking within the left engine pylon structure is a key focus of its investigation into the crash of UPS Flight 2976, according to a preliminary report released Thursday.
