A nine-member investigation team on Tuesday visited the crash site of the ill-fated Pakistan International Airlines (PIA) flight PK-661 near Havelian.
The team comprises of three French officials and three Canadian officials belonging to France-based aircraft manufacturer ATR and US-based engine manufacturer Pratt & Whitney. Three Pakistani officials are also part of the team visiting crash site.
The Pakistani officials are members of the Safety Investigation Board (SIB) of the Aviation Division.
The team is currently interviewing eyewitnesses of the crash and rescue teams that arrived on the site immediately after the incident.
The team will collect evidence from the site in order to investigate the cause of the crash. The evidence will be taken to Islamabad and France for examination.
PIA flight PK-661 carrying 48 passengers and crew crashed on the way to Islamabad from Chitral last week, killing all on board.
A 10-member special investigation team, headed by Group Capt Sultan and comprising high-ranking PAF and other officials, also visited the crash site last week and collected evidence from the wreckage of the plane to find causes of the accident.
PIA had earlier said both engines of the aircraft were fully operational at the time of take-off from Chitral and “some problem developed during flight”.
