The aircraft departed Bangalore for flight IC557 to Mangalore. After the aircraft became airborne, Mangalore weather was passed to the aircraft indicating deterioration in weather with conditions below minima. The aircraft arrived near Mangalore uneventfully and ATC informed that it was raining and the visibility was 1,000 metres. Therefore, the commander decided to hold the aircraft. A few minutes later, ATC informed that the visibility had improved to 2,000 meters and clouds were 4/8 at 700 feet. Thereafter, the aircraft was instructed to descend to 3,550 feet. Having sighted the runway, the captain turned right to position the aircraft for a left-hand downwind leg of the runway. However, ATC cautioned that the south of the runway was full of low cloud. Therefore, the aircraft took a left-hand circuit for landing. The aircraft landed almost on the middle of the runway at high speed, under adverse weather conditions. The aircraft could not be stopped within the available field length. Its nose wheel was sheared off and the aircraft continued skidding forward and nosed over into a valley beyond the airport plateau and came to stop against two huge boulders on the steep rocky terrain. The aircraft was substantially damaged. Five passengers and two cabin crew received minor injuries. There was a fire under the left-hand engine/wing which was extinguished.

The crew was completing a local training flight at Yellahanka AFB. After touchdown, the airplane bounced several times, went out of control, veered off runway and came to rest in flames. A crew member was killed while two others were injured.

Flight 106 departed from HAL Airport, Bangalore for Bombay at 1555LT on a scheduled domestic flight with 6 crew and 30 passengers on board. After a normal takeoff and climb, the aircraft was cruising at flight level 85 with the engines operating at 29" manifold pressure and 2050 rpm. BMEP gauges were not fitted. At 16:30 hours the flight reported its position 100 miles out from Bangalore and estimated Bombay FIR boundary at 17:00. The flight was uneventful up to about 16:50 when the pilot heard a loud "thud" which he believed to be an engine misfiring. This was followed by the aircraft losing height rapidly. The auto pilot was disengaged and the aircraft was trimmed for manual flight. In order to maintain height the pilot applied climb power, and then METO power by moving the pitch and throttle controls forward, and although the manifold pressure increased first to 35" and then to 40", the engine speed remained constant at 2050 rpm and the aircraft continued to lose height at a descent rate of 1500 feet per minute. Cylinder head temperatures were not apparently noted. The pilot eventually made a wheels-up landing in a ploughed field at an elevation of 1900 feet. All 36 occupants were evacuated safely while the aircraft was damaged beyond repair.

Shortly after liftoff, the airplane went out of control and crashed. A crew member was killed while all other occupants were injured. The aircraft was damaged beyond repair. It appears that the loss of control occurred while the autopilot system was already engaged at takeoff.

While cruising in low visibility, the aircraft hit the slope of mountain located near Katagaru, State of Karnataka. The aircraft was destroyed by impact forces and all 27 occupants were killed.

En route, the captain was forced to attempt an emergency landing for unknown reason. While landing in a field near Kolar, some 60 miles east of Bangalore, the aircraft lost its undercarriage and ended up in flames. While there was no casualties, the aircraft was destroyed by fire.

Shortly after takeoff from Hattargi, while in initial climb, the single engine aircraft impacted a tree and crashed. The pilot was injured and the passenger was killed.
