Circumstances:
Following an uneventful flight from Pittsburgh-International Airport, the crew deliberately started the descent prematurely, causing the aircraft to approach below the minimum published altitude. While descending in marginal weather conditions, the twin engine airplane struck an ILS antenna and crashed few dozen yards short of runway 33 threshold. A pilot and four passengers were seriously injured while 12 other occupants were killed. The aircraft was destroyed. By reason of numerous violations, unsafe practices, policies, and coercing tactics, Air East has demonstrated that it does not possess the judgement, responsibility or compliance disposition required of a holder of an air taxi commercial operators certificate. Thus, the operator's AOC was revoked on March 7, 1974.
Probable cause:
It was determined that the accident was caused by a premature descent below a safe approach slope followed by a stall and loss of aircraft control. The reason for the premature descent could not be determined, but it was probably the result of the combination of the following factors:
- A deliberate descent below the published minimum descent altitude to establish reference with the approach lights and make the landing,
- A visual impairment or an optical illusion created by the runway/approach lighting systems,
- Downdrafts near the approach end of the runway.

Circumstances:
Monmouth Airlines Flight 98 departed Wilkes-Barre at 2253LT for a short IFR flight to Allentown. Allentown Approach Control cleared the flight for a VOR approach and instructed the pilot to report when it was 12 miles North of the Allentown VOR. At 2307LT, upon receiving the flight's position estimate, Allentown Approach Control cleared Monmouth 98 for a VOR approach to a landing on runway 06. Monmouth 98 was requested to report when inbound over the Allentown VOR. The airplane then collided with the ridge of Blue Mountain at an elevation of 1540 ft (470 m). The wreckage was found 11,3 miles north of Allentown-Bethlehem Easton Airport. Both pilots and two passengers were killed while four other passengers were injured. The aircraft was destroyed.
Probable cause:
The pilot's nonadherence to approved approach procedures for executing a non precision instrument approach in instrument flight conditions. The Board further finds that there is a high degree of probability that the extensive on-duty time and actual instrument flight time prior to this accident resulted in the fatigue of both pilots and affected their judgment and decisions during the approach.

Circumstances:
On approach to Killeen Airport, the crew encountered marginale weather conditions with fog and ceiling. He was informed from ATC about a visibility below minima but the captain decided to continue the descent until the aircraft struck the ground short of runway and came to rest. The aircraft was damaged beyond repair and all 15 occupants were injured, nine of them seriously.
Probable cause:
Improper IFR operation on part of crew. The following factors were reported:
- Low ceiling and fog,
- The pilot knew that weather was below VOR minimums from ATC and another pilot who had to divert to alternate airport.

In a limited visibility, the twin engine aircraft struck the ground and came to rest in a swampy area located few dozen meters short of runway 18 threshold. All 17 occupants escaped uninjured while the aircraft was damaged beyond repair. At the time of the accident, the airport was not equipped with an ILS system.

Circumstances:
Air South Flight 168 departed Atlanta at 21:07. At 21:13 the flight reported level at its assigned cruising altitude of 7,000 feet. The Beech had been cruising for eleven minutes when it attained a gradual nose down attitude due to a change in the longitudinal trim. The pilots noticed the change after about six seconds and initiated a recovery action. The horizontal stabilizer continued to move to a full nose down position. Excessive pulling force on the control column was necessary to recover from the high speed dive. The necessary stick forces for such an out-of-trim condition can exceed the capability of one pilot, and in some cases two pilots, to control. The Beech continued to descend until both wings failed at high speed, just before the airplane crashed into the ground in a near vertical attitude.
Probable cause:
An unwanted change in longitudinal trim which resulted in a nosedown high-speed flight condition that was beyond the physical capability of the pilots to overcome. The initiating element in the accident sequence could not be specifically determined. However, the design of the aircraft flight control system was conducive to malfunctions which, if undetected by the crew, could lead to a loss of control.

Circumstances:
Shortly after takeoff from Pasco-Tri-Cities Airport, while in initial climb, the airplane adopted a high angle of attack and nose high attitude. It stalled then crashed in a huge explosion near the airport, killing both pilots.
Probable cause:
Inadequate preflight preparation on part of the pilot and improper operation of flight controls on part of the copilot. It was determined that the airplane pitched up steeply after takeoff as the pitch trim was found in a full nose up position and the pilot-in-command's seat was unlock and found in a full aft position.
