From the Wikipedia article
The Business Express accident off Block Island occurred on 28 December 1991 during a training flight of the regional airline Business Express Airlines with a Beechcraft 1900C from Igor I. Sikorsky Memorial Airport in Bridgeport, Connecticut. All three people on board were killed when the aircraft crashed into the Atlantic Ocean near Block Island.
Flight sequence
The aircraft took off from Sikorsky Memorial Airport at 18:45. No flight plan was filed; this was not required for the proficiency check flight to be conducted.
After the aircraft had previously flown a course that can no longer be reconstructed, it approached the island of Block Island at around 20:00 and then landed at the island's airport. The three pilots, who according to witness statements appeared fit, got out and discussed technical details of the aircraft before boarding it again and taking off from runway 28 between 20:45 and 21:00. After a short flight the aircraft landed at the airport again and remained parked there for a few minutes with its engines running. It then took off again, but air traffic control did not monitor the aircraft's direction of flight. The aircraft, which was scheduled for a passenger flight on 29 September at 10:00, did not return to any of the airports used by the airline. At 9:30, i.e. half an hour before the scheduled passenger flight, the airline reported the aircraft missing.
Investigation and cause
Cause
On 29 September, from 7:30, fishermen near Block Island sighted aircraft debris floating in the sea. It was later confirmed that the debris belonged to the missing Business Express Beechcraft 1900C. It was established that the check captain had deactivated the attitude indicator in flight while a simulated engine failure under instrument flight was being flown with the aircraft. The pilot in training, who was flying the aircraft, was said to have then had difficulty maintaining control of the aircraft owing to a partial loss of orientation. He was said to have asked the instructor to take control of the aircraft, which the latter, however, refused. A loss of control was then said to have occurred and the aircraft crashed into the sea. In addition, the accident had occurred on a moonless night, so that visual reference points were not available as orientation aids.
The accident investigation found that the check captain had dimmed the lighting of his own flight instruments, so that the examinee could not look across at them either. Neither the operator nor the Federal Aviation Administration was said to have been aware that the check captain used the area around Block Island for pilot training, nor was it known what methods he used in doing so.
A loss of altitude awareness by the check captain and possible spatial disorientation were determined to be the causes of the accident. As a result of these factors, control of the aircraft was said to have been lost at an altitude from which the Beechcraft could no longer be recovered. The operator's deficient supervision of the flight training programme with the Beechcraft 1900 was given as a further factor. The actions of the check captain, in that he put the aircraft into a configuration and attitude that left little margin for error, were given as a contributing factor.

NTSB narrative
THE PURPOSE OF THE FLIGHT WAS TO PREPARE TWO FIRST OFFICERS FOR A CAPTAIN UPGRADE FLIGHT. THE INSTRUCTOR PILOT DISABLED THE STUDENT'S ATTITUDE INDICATOR DURING FLIGHT, AND THE STUDENT HAD DIFFICULTY MAINTAINING AIRPLANE CONTROL. DURING A SIMULATED INSTRUMENT APPROACH, WHILE IN THE PROCEDURE TURN, THE INSTRUCTOR SIMULATED AN ENGINE FAILURE IN ADDITION TO THE ATTITUDE INDICATOR FAILURE. THE STUDENT ASKED THE INSTRUCTOR TO TAKE CONTROL OF THE AIRPLANE BECAUSE HE BECAME DISORIENTED, HOWEVER, THE INSTRUCTOR REFUSED. THE INVESTIGATION REVEALED THAT THE INSTRUCTOR WOULD TURN HIS OWN FLIGHT INSTRUMENT LIGHTS TO THE 'DIM' POSITION WHEN THE STUDENT WAS FLYING SO THAT HE COULD NOT 'PEEK' AT THE OPERABLE ATTITUDE INDICATOR. EXAMINATION OF THE WRECKAGE REVEALED THAT THE INSTRUCTOR'S LIGHT RHEOSTAT WAS IN THE DIM POSITION. THE ACCIDENT OCCURRED OVER THE OCEAN, ON A MOONLESS NIGHT. NEITHER THE OPERATOR, NOR THE FAA WERE AWARE THAT THIS INSTRUCTOR WAS USING BLOCK ISLAND FOR TRAINING, OR WHAT TRAINING METHODS HE WAS EMPLOYING.
Probable cause
THE INSTRUCTOR PILOT'S LOSS OF ALTITUDE AWARENESS AND POSSIBLE SPATIAL DISORIENTATION, WHICH RESULTED IN THE LOSS OF CONTROL OF THE AIRPLANE AT AN ALTITUDE TOO LOW FOR RECOVERY; AND COMPANY MANAGEMENT'S LACK OF INVOLVEMENT IN AND OVERSIGHT OF ITS BEECHCRAFT 1900 FLIGHT TRAINING PROGRAM. CONTRIBUTING TO THE ACCIDENT WAS THE INSTRUCTOR PILOT'S EXERCISE OF POOR JUDGMENT IN ESTABLISHING A FLIGHT SITUATION AND AIRPLANE CONFIGURATION CONDUCIVE TO SPATIAL DISORIENTATION THAT AFFORDED THE PILOTS LITTLE OR NO MARGIN FOR ERROR.
