Pakistan Civil Aviation Authority (CAA) has said that it is “doing its best to assist” Pakistan International Airline (PIA) in evaluating the current condition of its ATR aircraft fleet, and the final decision lies with PIA and the original manufacturers (OEM) of the aircraft to determine whether its engines are cleared for operation or not.
CAA Deputy Director General Nadeem Sharif Pasha stated in the letter, sent to PIA and dated December 13, that though the shakedown inspections of all ATR aircraft are underway, the “inspections of internal conditions of ATR engines is beyond our (CAA) scope”.
He stated that “significant observations” were made when the technical records of all aircraft were reviewed.
“The results of audits conducted by airworthiness field offices are indicating shortcomings in maintenance, quality assurance and Airworthiness Management System of PIAC,” the letter added.
The CAA letter added that engine trend analysis and health monitoring of engines is the responsibility of PIA, and the CAA has collected the statistical data of total engines failed since the induction of the ATR aircraft.
“The analysis of data is reflecting an alarming trend of engine failures due to HPT blades, main bearings, surging and oil system issues,” said the CAA letter sent to PIA.
