Cargo Plane Vanishes Off Karachi Coast After Reporting Navigation Fault

For three minutes, air traffic control was talking a crew through a routine navigation fix. Then the aircraft dropped off radar entirely.

The Pakistan Airports Authority confirmed a K2 Airways Boeing 737 cargo flight carrying five crew members went missing over the Arabian Sea late Tuesday, roughly 155 nautical miles west of Karachi, triggering a coordinated search and rescue operation.

How the Flight Unraveled

Flight KTA-1732 was en route from Sharjah to Karachi when, at 21:18 PST, the crew reported a navigational system issue and was guided by the Karachi Area Control Centre, according to the Pakistan Airports Authority.

Just three minutes later, at 21:21 PST, the aircraft was observed on radar rapidly descending with a rapid heading change, and radar contact and communication were lost shortly after.

Officials said the causes of the incident will be determined through investigation, and have not yet confirmed the aircraft's fate.

What the Flight-Tracking Data Shows

Flightradar24's technical analysis found the aircraft's ADS-B data showed an initial loss of altitude, followed by a climb, then a second, sudden and dramatic descent.

The final received data point placed the aircraft at 1,100 feet with a reported vertical rate of -22,400 feet per minute, an extreme descent rate that would be consistent with a loss of control rather than a controlled emergency landing attempt.

Separately, Flightradar24 noted the aircraft experienced GNSS interference shortly after takeoff near Sharjah, along with all other aircraft in that region at the time, degrading tracking data before the plane transitioned to a different tracking method.

The Search Effort

The Pakistan Airports Authority said a rescue coordination centre was activated and a coordinated search and rescue operation was launched at sea through various agencies to locate the missing aircraft.

As of the most recent updates, no official statement has confirmed a crash or provided details on the condition of the five crew members aboard.

Several unofficial reports have suggested the aircraft may have gone down in the Arabian Sea, though Pakistani authorities have not confirmed this, and TheTrendsWire is treating those reports as unconfirmed pending an official statement.

What's Known About the Aircraft

Aviation sources have identified the missing plane as a Boeing 737-400 registered AP-BOI, operating the K2 Airways cargo route between Sharjah and Karachi.

K2 Airways operates cargo services across the Gulf-Pakistan corridor, a route frequently used for freight moving between the UAE and Pakistan's largest port city.

Why This Route and Region Matter

Karachi's airspace sits along one of the busier Gulf-to-South Asia cargo corridors, and the specific combination of a reported navigational fault followed by an unexplained rapid descent will likely draw scrutiny toward both the aircraft's onboard systems and the surrounding electronic environment, given the GNSS interference reported just after departure.

Search and rescue operations at sea, particularly at night, typically take considerably longer than land-based searches, and officials have not provided a timeline for when more definitive information might be available.

TL;DR

• A K2 Airways Boeing 737 cargo flight with five crew members went missing over the Arabian Sea late Tuesday.

• The aircraft reported a navigation fault, then rapidly descended and lost radar contact 155 nautical miles west of Karachi.

• Flight-tracking data showed a final vertical descent rate of -22,400 feet per minute.

• A multi-agency search and rescue operation is underway; no crash has been officially confirmed.

• The aircraft experienced GNSS interference near Sharjah shortly after takeoff, along with other aircraft in the area.
