All Puerto Rico

Shortly after takeoff, the aircraft's climb performance began to deteriorate and the right engine started to overheat. Subsequently, the right engine was feathered and the crew attempted to return to the airport. The radio transmitter became unintelligible, so the tower personnel cleared the aircraft to land on runway 10 and asked the crew to key their mike twice, if they understood. The mike waskeyed twice. The aircraft entered a right downwind for runway 10 at a very low altitude. According to witnesses, the aircraft went into a steep bank as it was turning onto a base leg over water, the right wing tip hit the water and the aircraft cartwheeled and crashed. The copilot reported that after feathering the right engine, the vmc of 84 kts was maintained; however, he believed the aircraft stalled just prior to impact. A teardown of the right engine revealed the edge of the #8 piston and its piston rings had failed. Metal filings were found in the oil and the oil pump was scored. There was evidence of oil starvation to the crankshaft journal, as well as piston slap associated with the ring failure.

Flight 901A departed the ramp in Vieques about 0755 with eight passengers aboard, all of whom had reserved seats and purchased tickets for Flight 901. The pilot of Flight 901A contacted the UNICOM as he taxied out to the takeoff end of runway 09. The UNICOM operator informed hym that there was no other traffic in the area. According to a mechanic at the airport, after takeoff, the airplane appeared to climb out normally; however, he said that as the airplane turned left in a crosswind departure pattern, it appeared to lose power when about 200 feet above the ocean. He stated that the airplane then gained about 50 feet, while in a nose-high attitude, and that he then heard the engines develop more power, before the plane descended into the ocean. The airplane had crashed into the ocean north of the departure end of runway 09 and about 1/2 mile off shore. The aircraft was destroyed and all nine occupants were killed.

The aircraft crash landed during a touch and go landing. The pilot said that the aircraft was caught in a windshear or violent downdraft and would not climb. He did not say why he was doing a touch and go landing with 9 passengers on board. The pilots account of the accident was: after touchdown I raised the flaps and set takeoff power. At 103 knots and with 500 feet of runway remaining the aircraft was lifted off. At about 150 feet agl and climbing I started to raise landing gear but the aircraft started to sink so I left gear down. The trees were moving violently. I felt I was caught in a windshear because of a sharp drop in airspeed and the aircraft quit performing. The aircraft continued sinking and I decided on a controlled crash to save the passengers. A witness stated he (the pilot) took off without enough power. I saw the plane with its nose high and tail low and I lost the plane when it went into the trees. The aircraft hit several citrus trees at a shallow angle of descent 1,200 feet from the end of the runway. The aircraft went 150 feet through the trees and 350 feet on the ground before stopping. All 11 occupants escaped uninjured.

At liftoff at San Juan-Luis Muñoz Marín Airport runway 10, the twin engine airplane banked left then crashed. All five occupants were injured, the pilot seriously.

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.

The pilot, apparently sole on board, was engaged in an illegal flight and attempted to land at night on a unsuitable terrain (runway closed). After landing, the twin engine airplane ground looped, struck a dirt bank and came to rest in flames. The pilot was not found and the aircraft was destroyed.

On final approach to San Juan-Isla Verde Airport, the pilot lost control of the airplane that crashed onto several houses located in the district of Barrio Obrero, about 4 km short of runway 10 threshold. The aircraft was destroyed and all six occupants were killed. Few people on the ground were injured.

On approach to San Juan-Isla Verde Airport, the crew recycled the landing gear but the right main gear remained retracted. The crew was contacted by the tower controller but the captain decided to continue the approach. 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.

En route from Charlotte Amalie to San Juan, while flying along the east coast of Puerto Rico, the left engine failed. The crew was attempting to feather the propeller when the right engine lost power. The captain reduced his altitude and ditched the airplane about 1,000 feet of the Río Grande district. All five occupants were rescued while the aircraft sank.

While approaching Vieques on a flight from Christiansted, both engines failed simultaneously. The pilot attempted to ditch the aircraft that crashed into the sea few miles offshore. Five passengers were killed and five other occupants were injured .
