Karachi/Lahore:  Days after a private airliner crash left 127 people dead in Pakistan; two major tragedies were averted on Sunday when two planes developed snags, sending authorities into tizzy at Lahore and Karachi airports.

In an incident, the fuel tank of a Shaheen Air aircraft began leaking as it was about to take off from Lahore airport, forcing the pilot to apply brakes before take-off, the Express News reported. Eyewitnesses said that as the plane was taking off, the fuel tank began leaking.

The 200 passengers on board the flight remained unhurt. They were shifted to the waiting lounge at the airport where they began protesting, demanding that they be flown in another airline, the paper said.

Earlier in the day, emergency was declared at Karachi airport when two tyres of an aircraft belonging to same airline burst during landing at a runway. The plane, with about 100 passengers aboard, was bound to land at the Jinnah International Airport when its landing gear malfunctioned, causing the tyre to burst from the pressure.

Embers that sparked from the rims were extinguished with the help of water. All passengers and flight crew were safe, the news report said. Following the Karachi incident, one of the major runways at Jinnah International Airport was shut down till 5pm and larger aircraft were being redirected to Nawabshah airport, however smaller aircraft continued to land on other runways.

Director General Civil Aviation Authority (CAA) Nadeem Khan Yousafzai has ordered an immediate inquiry into the incidents. CAA spokesman Pervez George told The Express Tribune that Defence Minister Ahmed Mukhtar has directed DG CAA to thoroughly check all aircraft of private airlines.
