PARIS: Work on the flight data and cockpit voice recorders of a crashed Pakistan International Airlines (PIA) plane will begin in France on June 2, investigators said on Saturday. “The mission on site (of the crash) is about to be completed,” BEA, the French air safety investigation authority for civil aviation, said on Twitter. It added that Pakistani investigators would fly to France along with the French team. Under international aviation rules, BEA investigators joined the Pakistan-led inquiry because the 15-year-old jet was designed in France. Later, the team visited the Civil Aviation Authority (CAA) headquarters where they were given a detailed briefing on the ongoing investigation by the Aircraft Accident and Investigation Board’s (AAIB) four-member investigation team.
