ISLAMABAD, July 8 (Reuters) - Pakistani rescuers scoured the waters around the presumed crash site of a Boeing cargo plane on Wednesday, hours after it lost contact with air traffic control on its way to Karachi with five crew members on board, Pakistan authorities said.
Prime Minister Shehbaz Sharif directed authorities to speed up search and rescue operations for the 27-year-old converted freighter, which went missing in the Arabian Sea after reporting a navigational system problem.
K2 Airways, the
plane's operator, said the crew comprised two pilots, two engineers and one support staffer. Authorities have made no official declaration on their status, although Sharif expressed his "heartfelt condolences" to their families.
The plane may have crashed into the sea southwest of Karachi after a series of sharp altitude changes before a steep final descent, according to flight-tracking service Flightradar24.
Authorities have launched a coordinated search and rescue operation at sea through various agencies, Pakistan Airports Authority said on Facebook. K2 Airways said it was cooperating with the Pakistan Civil Aviation Authority and other government agencies. Boeing has not yet commented.
The plane reported a navigational system issue at 9:18 p.m. Pakistan Standard Time (1618 GMT) while flying towards Karachi, the airports authority said.
Local air traffic control tried to guide it but three minutes later radar systems showed the plane descending rapidly and communication was lost, the authority said. The flight was about 155 nautical miles (287 km) west of Karachi at the time, according to the statement.
The final minutes of Flightradar24's tracking data appeared chaotic, showing the plane plunging about 5,000 feet in less than a minute before soaring about 6,000 feet in 30 seconds and then entering a catastrophic dive from 36,550 feet.
The last transmitted data point placed the aircraft at 1,100 feet above sea level, with a vertical rate of minus 22,400 feet per minute — about 400 kilometres per hour — an extremely steep and abnormal rate of descent.
The missing aircraft is one of Boeing's decades-old 737-400s, two generations older than the 737 MAX that has been involved in a safety crisis. It uses engines made by CFM International, jointly owned by GE Aerospace and France's Safran.
The 737-400 was first delivered as a passenger plane to Russia's Aeroflot in 1999 and was converted to a freighter in 2012, according to Flightradar24. It is K2 Airways' only aircraft and entered service with the carrier in 2024. Its previous flight was on June 28, according to Flightradar24 data.
The incident would be Pakistan's first fatal crash since 2020, when a Pakistan International Airlines Airbus A320 came down short of the runway in Karachi, killing 97 people.
