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:
On final approach to Hopewell Airport, the pilot encountered poor visibility and was unable to locate the runway lights. He failed to execute a missed approach and continued to descend until the airplane struck trees and crashed in flames in a wooded area. All five occupants were injured and the airplane was destroyed by a post crash fire.
Probable cause:
The accident was the result of improper IFR operation on part of the pilot. The following factors were considered as contributing:
- Low ceiling,
- Obstruction to vision,
- The pilot did not execute a missed approach when runway was not in sight,
- The visibility was reduced due to smoke from a local factory and fog.

Circumstances:
Following an uneventful training mission of seven hours, the crew was returning to Minot AFB, North Dakota. On final approach by night, the crew encountered technical problems with the engines. Apparently due to low speed, the airplane stalled when four crew members managed to bail out. The aircraft crashed in an open field located eight miles from the airbase and was destroyed. Two crew members were rescued while four others were killed. The pilot ejected but was hit by a falling hatch after ejection and fatally injured. Sgt Blazina bailed out low and hit the ground before his chute opened.
Those killed were:
Lt Col Poole,
Maj McGuirk,
Sgt Cole,
Sgt Blazina.
Probable cause:
Fuel mismanagement on approach caused multiple flame‑out on engines number 1, 2, 3 and 4. Also, it is believed the approach speed was low at that time, causing the aircraft to stall.

On final, the crew failed to realize his altitude was too low when the right main gear struck a blast pad located 102 feet short of the runway threshold and was torn off. The airplane partially belly landed and slid for dozen yards before coming to rest. While all 11 occupants escaped uninjured, the aircraft was damaged beyond repair.
Probable cause:
The student pilot misjudged the distance and altitude on final and the pilot-in-command failed to supervise the flight adequately.
