The first aircraft was a Boeing 737-2R4C Adv., Which was finally assembled at the Boeing plant in Renton , Washington state and which completed its test flight on April 24, 1979 with the test number N1269 . The machine was ordered by the South Yemeni Alyemda , where the machine with the aircraft registration 7O-CAI should go into operation. Ultimately, the Alyemda did not accept the machine. On December 12, 1979, the Busy Bee of Norway finally took over the brand new machine and registered it with the aircraft registration LN-NPB . The aircraft had the factory number 21763, it was the 571st Boeing 737 from ongoing production. In October the machine was sold to the leasing company CIS Air Corporation , which leased the machine back to the Busy Bee of Norway. From May 1989 Shannonair Leasing Ltd. the new owner and lessor of the machine. After the leasing contract expired, the aircraft was registered with the aircraft registration number N801WA and was supposed to go into operation with Aloha Airlines , which Boeing did not accept. The machine was finally sold to the leasing company GAC USA Inc. , which leased the machine with the US aircraft registration N401MG to Sahara India Airlines from October 1, 1993. On November 1, 1993 the machine received the Indian aircraft registration VT-SIA . The twin- engined , narrow -body aircraft was equipped with two Pratt & Whitney JT8D-17A engines.
There was a four-person crew on board the Boeing 737, consisting of three pilots in training and a flight captain.
Ilyushin Il-86 of Aeroflot
The second machine was an Ilyushin Il-86 of Aeroflot from Soviet production with the factory number 51483209087. The roll-out of the machine at the Voronezh aircraft factory (VASO) took place in September 1991, then the machine completed its maiden flight on October 4, 1991. On the same day, it was delivered new to Aeroflot. The Ilyushin carried the Soviet aircraft registration number CCCP-86119 when it went into operation . After the collapse of the Soviet Union and the large-scale restructuring of Aeroflot, the aircraft remained in contrast to most aircraft of Soviet design, which Aeroflot approved with the new, Russian aircraft registration RA-86119 . The four - engine long - haul wide - body aircraft was equipped with four Kuznetsow NK-86 turbojet engines.
On board the Ilyushin Il-86 were two Aeroflot employees, a Russian ground technician and an airport employee.
the accident
On the day of the accident, the Ilyushin Il-86 was in an unscheduled position at Delhi Airport. Due to technical problems, it had turned back there, serviced and refueled with 52 tonnes of kerosene for an onward flight. There were no passengers on board. Two Aeroflot employees, a Russian ground technician and an airport employee were on board the plane and inspected it.
A training flight was carried out on that day with the Boeing 737-2R4C of Sahara India Airlines, a test captain practiced touch-and-go maneuvers together with three pilots to be tested . Five such maneuvers were successfully completed in a row. After the machine had lifted off runway 28 for a sixth touch-and-go maneuver, it suddenly rolled to the left after a climb to 400–500 feet (120–150 meters) and crashed onto the apron of the airport's international terminal. The burning debris slid against the Ilyushin Il-86, which then caught fire and was also destroyed. All eight people on board the two aircraft died, and an employee of an airport fuel company on the apron was killed.
root cause
In the final report on the incident published in November 1996, an error was found in the operation of the rudder by the pilot who was piloting the aircraft at the time of the accident. This error occurred when an engine failure was being simulated.
The elevator control unit of the Boeing 737 was examined on November 14, 1994 in the presence of employees of the National Transportation Safety Authority of the United States (NTSB) at the factory of the manufacturer Parker-Hannifin in Irvine , California . It was found that the component had already been serviced by a company other than the manufacturer. A serial number was stamped on it that did not match the original Parker-Hannifin serial number. A servo valve test was carried out, which found that the elevator could be adjusted in full deflections or partial failures so that the mechanism worked backwards. This was because the adjustment spring of the mechanism was modified to a different configuration, which would have corresponded to the installation in a Boeing 707 .
The responsible investigator from the USA informed the Indian side of the findings, but these were not found in the later final report. When the US investigators later objected to this, they received no response from the Indian side.
