A fractured turbine blade triggered a “complicated” sequence of failures that culminated in the fatal Havelian PIA crash in 2016, the Aircraft Accident Investigation Board of Pakistan has said in a report.
“The dislodging / fracture of PT-1 blade of No 1 Engine occurred after omission from the EMM (Non-Compliance of SB-21878) by PIA Engineering during an unscheduled maintenance performed on the engine in November 2016, in which the PT-1 blades had fulfilled the criteria for replacement, but were not replaced,” according to a report.
The report said that in February 2017, PIA Engineering reviewed the life of the old design PT-1 blades. “PIA Engineering decided to change the soft life as a hard life of 10,000 hrs irrespective of the conditions given in the maintenance manual (an action overboard towards safe side).”
