Colombia's GRIAA reported they have opened an investigation to determine the causes of and damage caused by the occurrence, when parts of the left engine of the A300 registration YV560T were ejected. The aircraft had just begun its takeoff run at 00:30L (05:30Z) when the crew rejected takeoff due to the failure of the left hand engine. Initial investigation by the investigators dispatched on site verified that a rotor disk had been ejected, impacted one of the runway safety meshes and subsequently collided with the door of a workshop located in an area surrounding the airport. There were no injuries.
On Mar 20th 2021 Colombia's GRIAA reported the aircraft was preparing for takeoff from runway 31R. At the threshold of runway 31R the crew accelerated the engines to about 75% thrust, when a loud bang occurred and the left hand engine shut down. The aircraft taxied back to the apron on its own using the right hand engine. The GRIAA recovered debris from runway and surrouning areas (maximum distance 400 meters) with the most distant part having been the low pressure turbine section. The occurrence was rated a serious incident.
Colombia's GRIAA released their final report in Spanish only (Editorial note: to serve the purpose of global prevention of the repeat of causes leading to an occurrence an additional timely release of all occurrence reports in the only world spanning aviation language English would be necessary, a Spanish only or no release does not achieve this purpose as set by ICAO annex 13 and just forces many aviators to waste much more time and effort each in trying to understand the circumstances leading to the occurrence. Aviators operating internationally are required to read/speak English besides their local language, investigators need to be able to read/write/speak English to communicate with their counterparts all around the globe).
The report concludes the probable causes of the serious incident were:
Failure of the left hand engine caused by fatigue loosening the low pressure turbine blades.
Contributing factors were:
- Non-Compliance with maintenance procedures by the operator by not complying with the manufacturer's requirements, laid out in FAA Airworthiness Directive 2012-02-07 issued on Nov 1st 2012, which required the replacement of the blades.
- Lack of an effective supplier verification programme at the operator and the lack of supervision and verification of borescopic results, which did not permit to identify and apply corrective measures to the erosion found on the tips of the blades during the previous inspection carried out 7 cycles before the occurrence.
