An investigation was done of the crash of PIA aircraft ATR42-500 back in 2016. The crash killed 47 people including Junaid Jamshed, Pakistani singer turned preacher. Now according to the Safety Investigation Board probe, it has been found that a ‘lapse’ by Pakistan International Airlines (PIA) and a ‘lack of oversight’ by the Civil Aviation Authority (CAA) led to this catastrophic incident.

A one-page preliminary report by SIB stated, “The investigation is nearing a concluding stage, however, some important findings of technical nature require immediate attention/intervention.”
SIB shared its report both with the national carrier and PIA.
PIA spokesman Mashood Tajwar said, “The SIB’s suggestions will be followed and a reply will be submitted by the airlines.”
According to the SIB report a blade of power turbine stage-1 dislodged due to fatigue. Due to thus an in-flight engine shutdown occurred and the No 1 propeller displayed absnotmal behavior, resulting in the crash. The blades should have been changed as they exceeded their 10,000 hours of use.
The report said, “Missing out of such an activity highlights a lapse on the part of PIAC (and a possible inadequacy/lack of oversight by the CAA.”
SIB suggested, “The PIAC should ensure immediate implementation of the service bulletin in letter and spirit on the entire fleet of ATR aircraft, undertake an audit of the related areas of maintenance practices, ascertain root causes for the said lapse, and adopt appropriate corrective measures to avoid recurrence of such incidents.”
