Circumstances:
On approach to San Juan-Isla Verde Airport, the right main landing failed to extend. The captain decided to complete two touch-and-go but the right main gear remained blocked in its wheel well. The decision to complete a belly landing was taken. After landing on runway 10, the airplane slid for few dozen meters before coming to rest. All three occupants escaped the scene and were not recovered. It was later reported that parts of the right main gear and the outboard five feet from the right horizontal stabilizer were missing.
Probable cause:
Suspected collision with object and subsequent wheels-up landing. The following findings were reported:
- Failed to see and avoid objects or obstructions,
- Intentional wheels-up landing,
- Forced landing on airport,
- Suspected or known aircraft damage,
- Right main landing gear struck unknown object.

Circumstances:
On approach to San Juan-Isla Verde Airport, the crew recycled the landing gear but the right main gear remained retracted.

The airplane partially slid on its belly for about 4,300 feet then veered off runway to the right and came to rest in a drainage ditch. All three occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wheels-up landing after the crew failed to assure the gear was down and locked. The following contributing factors were reported:
- Failed to follow approved procedures,
- Improper emergency procedures,
- Landing gear: normal retraction/extension assembly.

Circumstances:
The four engine airplane was engaged in a humanitarian flight from Miami to Managua with an intermediate stop in San Juan, carrying three crew members, two passengers (among them the famous American Baseball player Roberto Clemente aged 38) and various goods for the victims of the recent earthquake in Nicaragua. The crew was cleared to takeoff from runway 08 at 1920LT. After rotation, the crew was instructed to turn to left according to departure procedures. Three minutes after takeoff, while in initial climb by night, the airplane suffered various technical problems, lost height, stalled and crashed into the sea few hundred meters offshore. Some debris were found floating on water and all five occupants were killed.
Probable cause:
It was determined that the loss of control was caused by the failure of the engine n°2 and a loss of power on engine n°3. The failure of the engine n°2 was caused by engine structure problems with master and connecting rods, cylinder assembly and piston rings. Investigations also determined that the aircraft was not properly maintained and inspected in accordance with the rules in force. Also, the flight engineer was not qualified for this type of aircraft. The following factors were reported:
- The aircraft was overloaded by 4,193 pounds (1,902 kg),
- Improperly loaded aircraft,
- Powerplant structure,
- Inadequate maintenance and inspection,
- Deficiency in the company maintenance program, violating services regulation,
- Previous damages.

Circumstances:
Two minutes after takeoff from runway 16 at Santo Domingo-Las Américas Airport, while in initial climb, the pilot informed ATC that the right engine failed and was cleared to return for an emergency landing. Shortly later, the left engine failed as well. Out of control, the airplane entered a dive and crashed into the Caribbean Sea about three km offshore. Few debris were floating on water and others sank by a depth of 300 meters. All 102 occupants were killed among them the Dominican boxer Carlos Teo Cruz, world lightweight champion as well as a large part of the Puerto Rico's National Women's Volleyball Team.
Probable cause:
Brand new, the aircraft was delivered by Douglas Corp to Dominicana de Aviación last 16 of December 1969. Only few debris were recovered and unfortunately, both CVR & FDR were not found. Due to lack of evidences, the exact cause of the accident could not be determined with certainty. However, it is believed that the double engine failure may have been caused by the contamination of fuel by an important quantity of water.

Circumstances:
Prinair flight PQ277 departed Charlotte Amalie Airport (Saint Thomas Island) at 1715LT for an IFR flight to San Juan. At 17:32, the flight contacted San Juan Approach Control and advised that the flight was maintaining 4,000 feet. The trainee approach controller replied: "Prinair two seven seven San Juan Approach Control radar contact three miles east of Isla Verde fly a heading of two five zero for a vector to ILS final maintain four thousand." Actually the flight was 3 miles east of the Fajardo intersection instead of the Isla Verde intersection which is located about 10 miles west of the Fajardo intersection. One minute later the Heron was cleared to descend to 3,000 feet. At 17:38, after being vectored for a runway 07 approach, the airplane contacted trees and crashed, coming to rest near the top of a knoll in the Sierra de Luquillo mountains at an elevation of about 2400 feet (731 m). The wreckage was found about 24 km southeast of San Juan-Isla Verde Airport and all 18 occupants were killed.
Probable cause:
The vectoring of the aircraft into mountainous terrain, under IFR conditions, without adequate obstruction clearance altitude by a controller who, for reasons beyond his control, was performing beyond the safe limits of his performance capability and without adequate supervision.

Circumstances:

After passing over the end of the runway, the airplane struck a house and crashed. The pilot, two passengers as well as four people on the ground were killed. Eight passengers were seriously injured.
Probable cause:
The accident was probably caused by the combination of the following factors:
- The pilot failed to obtain/maintain flying speed,
- Inadequate preflight preparation,
- The aircraft computed to be loaded to aircraft CofG limits,
- No W&B prepared by the pilot,
- Possible misuse of flaps.
