THE READOUT of the flight data recorder (FDR) and the cockpit voice recorder (CVR) of XiamenAir flight MF8667, which were brought to Singapore last Aug. 23, has been returned to Manila last Friday, but the investigation on the incident that caused chaos last month at the Ninoy Aquino International Airport is still ongoing. “Under international and Philippine aviation rules, substantial content of the FDR and CVR readouts still cannot be disclosed until the final report,” the Civil Aviation Authority of the Philippines (CAAP) said in a statement yesterday. It added that the CAAP Aircraft Investigation and Inquiry Board (AIIB) has “confirmed that the black box data recording was of good quality.” The AIIB’s investigation is meant to identify safety breaches, while a separate probe by the CAAP-Flight Safety Investigation Committee aims to determine possible breaches against civil air regulations.
