Circumstances:
While approaching Albany-Dale Hollow Airport, the pilot was cleared by ATC to descend to 3,500 feet when he reported he was going to 'scoot down' under layer. In limited visibility due to poor weather conditions, the twin engine airplane struck trees and crashed on a mountain slope at an altitude of 1,700 feet. All three occupants were killed.
Probable cause:
Collision with trees and subsequent crash after the pilot-in-command exercised poor judgment. The following contributing factors were reported:

Circumstances:
Airtankers "T1" (N96449, msn 10750) and "T2" (N406WA, msn 35955) both Douglas DC-4's, departed the Hemet-Ryan Field, CA (HMT) about 13:22. Both airtankers had been recently released by the Forest Service from southern California fire assignments and were headed for their home base in Tucson, Arizona. While enroute, the crew of T1 engaged in taking in-flight photographs of T2 at an altitude of approximately 9,500 feet. T1 was flying in formation with T2 at his four to five o'clock position. The pilot of T1 stated over the radio that they were going to cross over to the other side of T2 to take more photographs. T2 gave permission and said that he would hold steady. The repositioning path T1 flew was a 45 degree overtaking angle from the four to five o'clock position toward the 10 to 11 o'clock position of T2. The vertical separation between the two airtankers was insufficient and a mid-air collision occurred. The vertical fin of T1 struck the right wing flap of T2. T1's fin and rudder were sheared off by that impact. The retardant tanks of T2 compressed the top aft end of the fuselage of T1. The number two propeller of T2 severed the fuselage of T1 approximately 10 feet in front of its horizontal stabilizer. T1's tail section was separated from the rest of the airtanker at that time, rendering it out of control. The pilot of T2 radioed Palm Springs Approach Control at 13:50, declared an emergency, and apprised them of the collision. T2 landed safely at the Palm Springs Airport at 13:56. After T1 experienced the tail separation, they lost altitude rapidly. T1 dropped debris for about a mile and a half until it cut through two power lines and then struck the earth nose first. There was a post-mishap fire. The captain and copilot were fatally injured. The tail section of T1 was found approximately two and a half miles from the main wreckage site. T2's damage consisted of damage to the right wing flap, scrapes and punctures to the retardant tank, damage to the right wheel compartment, badly "chewed up" propeller blades on the number two engine, a hole in the left wing, a dented left horizontal stabilizer on the tail, and various other damage.

Circumstances:
While in normal cruise from Brownsville to Atlanta, the pilot reported engine problems. He elected to divert to the nearest airport but was eventually forced to attempt an emergency landing. The aircraft belly landed on soft ground and came to rest. All seven occupants were rescued, among them five were seriously injured.
Probable cause:
Propeller blades failure in flight due to corrosion. The following contributing factors were reported:
- Fatigue fracture,
- Engine structure: mount and vibration isolators,
- Overload failure,
- Wet and soft ground,
- Forced landing off airport on land,
- Wind gusting to 24 knots,
- Propeller blade failed due to fatigue,
- Originating at stress corrosion crack.

While descending to Driggs-Reed Memorial Airport by night and foggy conditions, the pilot lost control of the airplane that entered an uncontrolled descent and crashed in an open field, bursting into flames. All six occupants were killed.
Probable cause:
Uncontrolled descent and subsequent crash after the pilot suffered a spatial disorientation while continuing VFR flight in adverse weather conditions. The following contributing factors were reported:
- Fog,
- Pilot fatigue,
- Visibility half a mile or less,
- Pilot engaged in normal work-day activities before departing Novato at 1830LT.

Circumstances:
After takeoff from Detroit-Wayne County Airport, while in initial climb, the pilot reported a loss of power on the left engine and elected to return for an emergency landing. He quickly realized he could not make it so he attempted an emergency landing in an open field. The airplane belly landed and slid for few dozen yards before coming to rest, bursting into flames. Both occupants were able to evacuate the cabin and were uninjured. The aircraft was destroyed by fire.
Probable cause:
Engine failure and subsequent wheels-up landing due to inadequate maintenance and inspection on part of the maintenance personnel. The following contributing factors were reported:
- Powerplant - exhaust system: manifolds,
- Material failure,
- Foreign object damage,
- Propeller and accessories: governors,
- Improperly secured,
- Failure of both engines,
- Wet and soft ground,
- High obstructions,
