LAHORE - Hours after the crash of a private airlines plane in Islamabad killing 152 passengers Pakistan Airline Pilots Association members have demanded an inquiry into the PIA international flight which made abnormal landing at Karachi Airport because of its over worked staff. They claimed that a PIA flight PK 736 made rough landing at Karachi and the abnormal landing was also felt badly by the passengers as well, said spokesman of the Pakistan Airline Pilots Association PALPA on Thursday. The spokesman said that an inquiry into the delay and exceeding of Flight Duty Time at (Night) should also be ordered for the crew of Boeing 747 on PK 735 from Karachi to Jeddah and PK 736 Jeddah to Karachi on 26th and 27th July respectively which were delayed at Karachi due to an incident wherein a catering van hit the aircraft and subsequently at Jeddah due to time slot. Both the flights were operated by the same set of crew, departing from Karachi as per schedule around 9:30 PM (actual departure after delay at midnight), and reaching Karachi (PK 736) around 9AM in the morning exceeding the single crew night flight duty time by more than 5 hours. Meanwhile, a spokesman for Pakistan Airline Pilots Association PALPA has rejected a claim from PIAs management that a go slow by pilots caused a delay on PK 787 to London.
