Some 48 passengers were off-loaded from the plane and the flight was cancelled.
The required parts from Islamabad were sent by flight to Skardu and the plane is expected to depart for Islamabad on October 6 after repairs.
This is the second PIA flight to be delayed due to a technical problem in recent weeks.
On August 31, a PIA flight from Islamabad to Gilgit was forced to return to the federal capital after developing a technical issue.
PIA has been facing financial difficulties in recent years and has been accused of neglecting maintenance of its aircraft.
The airline is currently in the process of being privatized.
Yesterday, PIA flight operations to Canada faced serious challenges of closure amid financial challenges.
Swissport Company issued a letter to stop providing ground-handling services as the national airline faced serious financial challenges.
“Due to non-payment of dues, PIA flight operation to Canada services are being stopped from 3rd October at 5 pm,” the statement read.
The Swissport Company demanded $248,000 dollars be paid immediately along with an advance of $100,000 dollars for provision of future services.
Later, PIA Spokesman Abdullah Hafeez said all payments had been made to the Swissport company and denied reports that the flight operations were suspended.
He said that the payment was delayed due to difference in time between the two countries.
Dues to the handling agency and the fuel company amounting to $200,000 have been paid, he said and confirmed that all PIA flights to Canada will operate normally.
Further, the national flag carrier is also working on a restructuring plan ahead of privatization.
Legal and corporate firms have been invited to submit applications to develop the restructuring plan.
The assets of the national airline, including property, debts, aircraft, and employees, will be transferred to the new company.
PIA will then be presented to investors as a debt-free organization for privatization.
The government's decision to privatize PIA is seen as a last-ditch effort to save the national airline, which has been plagued by financial losses and mismanagement for years.
