Pakistan located the wreckage of a Boeing cargo plane on Wednesday, the country's airports authority said, adding that rescuers were searching for the five crew on board when the aircraft had gone missing.

The plane was approaching Karachi from Sharjah in the United Arab Emirates when radar showed it "rapidly descending" on Tuesday evening after reporting a "navigational system issue", according to the Pakistan Airports Authority (PAA).

Pakistan's navy and maritime rescue agency, after searching for 12 hours, "successfully located and identified wreckage of K2 Airways Cargo B737 which was declared missing last night," the PAA said in a statement posted on X.

The wreckage was found in the Arabian Sea, off Ormara town on Pakistan's southern coast, it said.

"Efforts are underway to find the missing crew members," the PAA added.

The authority published images of personnel lifting pieces of the fuselage from a small boat onto a larger vessel and the red and white debris with the words "K2 Air" laid out on the ship's deck.

In a statement issued before the plane wreckage was found, Prime Minister Shehbaz Sharif expressed "deep sorrow, grief, and regret over the tragic incident in which a private cargo aircraft... crashed into the Arabian Sea and went missing."

The aircraft was observed on radar at 21:21 pm (1621 GMT) on Tuesday "rapidly descending and with rapid heading change,", and communication contact was lost about 155 nautical miles west of Karachi, the PAA said.

Preliminary data sent from the plane "indicated a loss of altitude, followed by a climb, and then a second, sudden and dramatic loss of altitude," according to Flightradar24.com, a global flight-tracking service.

K2 Airways is a private cargo airline in Pakistan that operates scheduled and charter flights domestically and internationally.

Manufactured in 1999, the aircraft flew as a passenger plane for Aeroflot and Garuda Indonesia before being converted to a cargo configuration in 2012, according to Airfleets.net. (AFP)
