Circumstances:
About 2055LT, Downeast Airlines flight 46 crashed into a heavily wooded area about 1,2 mile south-southwest of the Knox County Regional Airport in Rockland, Maine. The crash occurred during a non-precision instrument approach to runway 03 in instrument meteorological conditions. Of the 16 passengers and 2 crew members aboard, only one passenger survived the accident. The aircraft was destroyed.
Probable cause:
The National Transportation Safety Board determines that the probable cause of the accident was the failure of the flightcrew to arrest the aircraft's descent at the minimum descent altitude for the non-precision approach, without the runway environment in sight, for unknown reasons. Although the Safety Board was unable to determine conclusively the reason(s) for the flightcrew's deviation from standard instrument approach procedures, it is believed that inordinate management pressures, the first officer's marginal instrument proficiency, the captain's inadequate supervision of the flight, inadequate crew training and procedures, and the captaints chronic fatigue were all factors in the accident.

Circumstances:
While descending to Newburgh-Stewart Airport by night and marginal weather conditions, the pilot informed ATC about icing conditions but was vectored for a holding pattern due to heavy traffic. On short final, the twin engine airplane stalled and crashed about 1,600 feet short of runway threshold. The pilot, sole on board, was seriously injured.
Probable cause:
Stall on approach due to improper in-flight decisions. The following contributing factors were reported:
- Airframe ice,
- Icing conditions including sleet, freezing rain,
- Visibility three miles or less,
- Fog,
- Pilot informed of icing at holding altitude prior to his entering holding.

Circumstances:
The pilot-in-command adopted a wrong approach configuration and passed over the runway 28 threshold at an excessive speed of 184 knots (61 knots above the Vref) in a nose down attitude. The nose gear landed first at a speed of 163 knots (40-45 knots above normal touchdown speed) 2,540 feet past the runway threshold (runway 28 is 5,500 feet long). Unable to stop within the remaining distance, the airplane overran, struck a drainage ditch, lost its undercarriage and came to rest 728 past the runway end. All 77 occupants were evacuated safely, one of them was slightly injured.
Probable cause:
The captain's lack of awareness of airspeed, vertical speed, and aircraft performance throughout an ILS approach and landing in visual meteorological conditions which resulted in his landing the aircraft at an excessively high speed and with insufficient runway remaining for stopping the aircraft, but with sufficient aircraft performance capability to reject the landing well after touchdown. Contributing to the accident was the first officer's failure to provide required callouts which might have alerted the captain to the airspeed and sink rate deviations. The Safety Board was unable to determine the reasons for the captain's lack of awareness or the first officer's failure to provide required callouts.

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:
Northeast Airlines Flight 946 departed Boston 17:42 for a flight to Lebanon, NH and Montpelier, VT. The Fairchild climbed to a cruising altitude of 8000 feet. At 18:08 the crew were cleared for an approach to the Lebanon Airport to cruise at 5,000 feet and report leaving 6,000 feet. At 18:10:45, the controller advised the crew that radar service had been terminated and the flight was cleared to contact the Lebanon Flight Service Station (FSS). One minute later the FSS told the crew that the weather was an estimated ceiling of 2,000 feet overcast; visibility was 10 miles; there were breaks in the overcast; the altimeter setting was 29:55; and the wind was calm. The flight did not perform the published instrument approach procedure but executed an abbreviated approach by making a right turn from their northwesterly heading and then a left turn back to intercept the inbound radial to the VOR station. The inbound radial was intercepted at approximately 8 to 10 miles northeast of the VOR station where it passed through an altitude of about 4500 feet. The crew began the descent but did not level off at 2,800 feet m.s.l., the minimum altitude inbound to the VOR. During the approach to runway 25 the airplane contacted trees on the cloud-shrouded side of a steep, rocky, heavily wooded mountain 57 feet below the summit at 2,237 feet m.s.l. The aircraft cut a swath trough the trees broke up and caught fire. Two crew members and 30 passengers were killed while 10 others were injured.
Probable cause:
The premature initiation of a descent towards the Minimum Descent Altitude, based on navigational instrument indications of an impending station passage in an area of course roughness. The crew was not able to determine accurately its position at this time because they had performed a non standard instrument approach and there were no supplement navigational aids available for their use.

Circumstances:
While cruising at an altitude of 15,500 feet over Holmdel, New Jersey, the aircraft suffered an explosive decompression of the cabin. A 60 by 125 inches 'panel' detached from the fuselage and struck the engine number three, causing the detachment of its propeller. The crew started an emergency descent and was able to complete an emergency landing at New York Airport. All 14 occupants were evacuated safely while the aircraft was later declared as damaged beyond repair.
Probable cause:
Fatigue fracture of the fuselage and explosive decompression caused by an inadequate maintenance and inspection on part of the ground maintenance personnel. Investigations reported that at the time of the decompression, the cabin was pressurized for 2,500 feet while the aircraft was flying at an altitude of 15,500 feet.

Circumstances:
Trans World Airlines, Inc., Flight 42, (TW 42), a Boeing 707, N748TW, and Eastern Air Lines, Inc., Flight 853, (EA 853), a Lockheed 1049C, N6218C, were involved in a midair collision over the Carmel, New York VORTAC while en route to the New York City area at approximately 1619 e.s.t., December 4, 1965. TW 42 departed San Francisco, California, and was approaching the New York area from the northwest for an approach and landing at the John F. Kennedy International Airport. The flight was on an IFR flight plan at an assigned altitude of 11,000 feet mean sea level (m.s.l.). EA 853 departed Boston, Massachusetts, and was approaching the New York area from the northeast for an approach and landing at the Newark Airport. This flight was on an IFR flight plan at an assigned altitude of 10,000 feet m.s.l. As EA 853 was approaching the Cannel VORTAC on a southwesterly heading, the first officer saw TW 42 at his two o'clock position. Because he believed the jet was at his altitude and on a collision course he called "Look Out" and grasped the control wheel to assist the captain in a pull up. At approximately the same time, the captain of TW 42 observed EA 853 at his ten o'clock position on what he believed to be a collision course. He rolled into a right turn and pulled back on the yoke. He decided this maneuver would not clear EA 853 and he, assisted by his first officer, attempted to reverse the turn by rolling to the left and pushing on the yoke. The aircraft collided at an altitude of approximately 11,000 feet m.s.l. While cruising at an altitude of some 10,000 feet over Carmel on approach to Newark, the four engine aircraft collided with a TWA Boeing 707-131B registered N748TW. While the crew of the B707 was able to complete an emergency landing at JFK Airport despite the fact that a piece of 7.5 meters from the left wing was torn off, the crew of the Constellation first lost control of his aircraft but then regain control and was able to make an emergency landing in a prairie located on Titicus mountain, near Carmel. Three passengers died, plus the Constellation's pilot, Captain Charles J. White, who had returned to the aircraft's cabin to help the last passenger.
Probable cause:
Misjudgment of altitude separation by the crew of EA853 because of an optical illusion created by the up-slope effect of cloud tops resulting in an evasive manoeuvre by the EA853 crew and a reactionary evasive manoeuvre by the B707 crew as well.
