Its 4 years ago, does it take that long. Besides the problem was in the engines that were made by Pratt & Whitney so why send it to ATR for re-examination. Seems like a delaying tactics.

If you look at the previous reports of engine related issues faced by ATRs in pakistan they all had the problem of having metal shavings on some sensor in the engine,AAIB had several times asked P&W to come up with a fix asap but it didn’t for some reason, The sensitive engine coupled with jerry rigging behavior of PIAs maintenance has wreaked havoc on the ATR fleet.

Today Sindh High Court was informed that:

PIA was responsible for airline's December 7, 2016, ATR 42-500 (AP-BHO) Chitral to Islamabad flight PK661 crash.

Pakistan's Aircraft Accident Investigation Board (AAIB) says that cockpit crew faced a very complicated technical problem after ATR engine breakdown.

The technical problem experienced by flight PK661 ATR had never happened before with this aircraft type. It became impossible for the cockpit crew to control the aircraft.

The technical fault in engine developed due to aircraft's poor maintenance performed by PIA.

What was that very "complicated technical problem" which had "never happened" before and made it "impossible for crew to control the acft"?

Aircraft Accident Investigation Board (AAIB) informed the court that ATR’s failure sequence was triggered because of fracture of turbine blade consequent to one procedure anomaly of PIA maintenance adding that had any one of these latent factors not existed and triggered by a blade failure, this complicated catastrophic sequence of failures subsequently leading to the crash could have been averted.

This paper (as per avherald) was presented in the court. However it simply states dislodging of one blade in PT1 on no 1 engine, which resulted in erratic. There is nothing which is a first in aviation history, and does not explain how failure of one engine can result into something which pilots could not control?
