Pakistan International Airlines (PIA) will suspend 150 pilots for holding "dubious licences".
They have been accused of obtaining licences by having others take exams for them following an inquiry into a PIA crash last month.
All the pilots under investigation would be grounded, said company spokesman Abdullah H. Khan.
It comes a day after the country’s aviation minister, Ghulam Sarqar Khan, said 262 out of 860 Pakistani pilots had "fake" licences.
The investigation into pilots' qualifications came after an investigation into a 2018 crash found that the test date on the licence of the pilot involved was a holiday suggesting it was a dummy.
