Captain / Total hours on type:

Circumstances:
The aircraft was performing a flight from Pittsburgh to Cincinnati with an intermediate stop in Parkersburg. Upon landing at Parkersburg Airport, West Virginia, the crew encountered technical problems with the right main gear. The captain increased engine power and decided to return to Pittsburgh-Greater Pittsburgh Airport for a safe landing. Upon touchdown on runway 28R, as the wheels were missing on the right main gear, the airplane deviated from the centerline to the right when the left main gear collapsed as well. The airplane came to rest and was damaged beyond repair while all 53 occupants escaped uninjured.
Probable cause:
The right main gear lower assembly separated at Parkersburg Airport after a worn lock pin in the upper bearing sheared. The crew diverted to Pittsburgh. Failure of the landing gear, main gear-shock absorbing, assy, struts, attachments, etc.

Aircraft flight hours:

Circumstances:
The aircraft departed Boston-Logan at 2028LT bound to Augusta with seven passengers and a pilot on board. At the origin, the flight was scheduled to Rockland but it was not possible to land there due to foggy conditions. The flight was cleared for a VOR approach at 2114LT. At 2127LT, flight 88 reported a missed approach and was cleared for another VOR approach at that time. At 2140LT, the flight reported 'four miles out'. This was the last known transmission made by the flight. The wreckage was located in a heavily wooded area on Allen Hill at approximately the 520 foot level. Allen Hill is a prominent terrain feature which is 640 feet high, located approximately 4 nautical miles from the threshold of runway 17 and eight-tenth of a mile west of the approach radial. The pilot and two passengers were killed, two passengers received serious injuries and three passengers received minor injuries.
Probable cause:
The NTSB determines that the probable cause of this accident was the improper action of the pilot in discontinuing the execution of a non-precision instrument approach and attempting to maintain visual flight while operating in instrument flight conditions at an altitude below the level of obstructing terrain.

Circumstances:
The descent to Jaipur-Sanganer Airport was initiated in poor weather conditions with heavy rain falls. Due to low visibility, the captain decided to make a go-around. Few minutes later, a second attempt to land was abandoned and a second go-around was completed. During a third attempt to land, the pilot-in-command landed too far down the runway, about 1,800 feet past the runway threshold. Unable to stop on a wet runway and within the remaining distance, the airplane overran, lost its left main gear and came to rest. All 27 occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration.

Circumstances:
After landing at Honolulu, the crew completed the braking procedure and vacated the runway to the parking when the cabin crew informed the pilot about smoke in the cabin. The airplane was immediately stopped and all 22 occupants were able to evacuate. There were no injuries but the aircraft was seriously damaged by fire and considered as written off.
Probable cause:
An undetected electrical short within the left nickel-cadmium aircraft battery, which resulted in the absorption or an increasing amount of heat energy over an unknown period of time and progressed to a state of thermal runaway.

Circumstances:
The crew was returning to Calcutta-Dum Dum on a ferry flight from Raipur. En route, he was informed that weather conditions worsened in Calcutta with a visibility limited to 2 km. While descending to an altitude of 1,830 meters, the wind component changed and the crew was vectored for an approach to runway 01R which was not equipped with an ILS system. On final approach, while at a distance of 4 km from the airfield, the airplane went through a low pressure area with heavy rain falls. At a distance of 900 meters from the runway threshold, at an altitude of 40/50 meters, the visibility dropped to zero due to torrential rains. ATC informed the crew about the minimums and the navigator advised the captain to initiate a go-around manoeuvre. But the captain continued the descent and passed below the glide until the aircraft struck the ground 198 meters short of runway threshold and 20 meters to the left of the centerline. It slid for several yards and came to rest in a swampy area. All seven crew members were rescued while the aircraft was damaged beyond repair.
Probable cause:
The airplane entered an area of heavy rains falls, reducing the visibility to zero. In a very short time, the crew lost visual contact with the runway and all visual references with the ground as well, causing the aircraft to pass below the glide and to struck the ground. For unknown reason, the captain failed to initiate a go-around manoeuvre and ignored the different warnings from ATC and his crew. The fact that the crew was not aware about the non precision approach procedures for runway 01R remained a contributing factor.
