Aircraft

The Boeing 747-200 was originally manufactured for South African Airways in 1980 as ZS-SAR, making its first flight on 24 October of the same year, and being delivered on 6 November.[2] At some point during its service with SAA, ZS-SAR was converted to a freighter. On 11 November 1992, ZS-SAR was leased to Garuda Indonesia as 3B-NAS. Sometime before September 1995, the aircraft was returned to SAA, and in March 2000, was sold to MK Airlines as 9G-MKJ.[3]

Accident

At 00:03 local time, on 14 October 2004, MK Airlines Flight 1602 took off from Windsor-Locks-Bradley International Airport. The aircraft was loaded with a cargo of lawn tractors, and made an intermediate stop at Halifax at 02:12 to be loaded up with approximately 53,000 kilograms (53 t; 117,000 lb) of lobster and fish.

Flight 1602 taxied to Runway 24 (now assigned '23' designation), and the takeoff roll was commenced at 06:53:22. When the aircraft reached 130 knots (150 mph), the control column was moved aft to 8.4° to initiate rotation as the aircraft passed the 5,500-foot (1,700 m) mark of Runway 24; with 3,300 feet (1,000 m) left on the runway, the aircraft began to rotate. The pitch attitude stabilized briefly at approximately 9° nose-up, with an airspeed of 144 knots (166 mph). Because the 747 still had not lifted off the runway, the control column was moved further aft to 10°, and the aircraft responded with a further pitch up to approximately 11°; at this time, a tailstrike occurred. The aircraft was approximately at the 8,000-foot (2,400 m) mark and slightly left of the center-line. The control column was then relaxed slightly, to 9° aft. The pitch attitude stabilized in the 11° range for the next four seconds, and the tailstrike abated as a result. With approximately 600 feet (180 m) of runway remaining, the thrust levers were advanced to 92% and the EPRs increased to 1.60. With 420 feet (130 m) remaining, a second tailstrike took place. As the aircraft passed the end of the runway, the control column was 13.5° aft, pitch attitude was 11.9° nose-up, and airspeed was 152 knots (175 mph). The highest recorded nose-up pitch of 14.5° was recorded at one minute and two seconds after takeoff initiation after the aircraft passed the end of the runway at a speed of 155 knots (178 mph). The aircraft became airborne approximately 670 feet (200 m) beyond the paved surface and flew a distance of 325 feet (99 m). The lower aft fuselage then struck an earthen berm supporting an instrument landing system (ILS) localizer antenna 300 metres (980 ft) beyond the end of the runway, separating from the plane. The plane then headed forwards in a straight line for another 1,200 feet (370 m), breaking into pieces and bursting into flames when it struck the ground.[4]

Rescue

Over 60–80 firefighters and 20 pieces of apparatus from Halifax Regional Fire and Emergency responded to the call. It took nearly three hours to extinguish the post-crash fire.[5]

Investigation

An investigation into the crash revealed that the flight crew had used the incorrect speeds and thrust setting during the take-off attempt, with incorrect take-off data being calculated when preparing the flight (incorrect V speed calculation, as the result of the crew re-using a lighter take-off weight of 240,000-kilogram (530,000 lb) from the aircraft's previous take-off at Bradley, instead of the correct weight of 353,000-kilogram (778,000 lb). The official report blamed the company for serious non-conformances to flight and duty time, with no regulations or company rules governing maximum duty periods for loadmasters and ground engineers, resulting in increased potential for fatigue-induced errors.[6]

MK Airlines disputed the findings, citing the fact that the cockpit voice recorder was too heavily damaged in the post-crash fire to yield any information.[7]
