Circumstances:
The aircraft was engaged in a local post maintenance test flight at Fort-de-France-Le Lamentin Airport, carrying five technicians and three crew members on behalf of the Escadron de Transport Outremer 58. After engine startup, the crew started to taxi when a fire erupted. The aircraft was stopped on the ramp and all eight occupants escaped uninjured. Within three minutes, fire bombers were on site and extinguished the fire. Nevertheless, the aircraft was damaged beyond repair.
Probable cause:
The accident was caused by electrical arcing at the power cable to a submersible fuel pump. This arcing occurred above the kerosene liquid inside the tank full of fuel vapors. The cable type used was chosen at the time of the design of the aircraft. Atmospheric conditions on the apron of Fort de France have raised the temperature of the reservoir beyond the flash point kerosene. The vapors contained in this tank were explosive, and the arc was enough to initiate the blast. As such, atmospheric conditions are a certain cause of environmental origin of the accident. The appearance of the arc is, in turn, has only technical causes:
- The quality of cable used and age are in fact responsible for the creation of the electric arc.
- The formation of the insulating sheath of this type of cable is not likely to ensure an absolute seal. This quality is also not claimed by its manufacturer.
Indeed, the analysis carried out show a porosity of electrical cable, even nine, therefore that it is soaked in kerosene. The presence of kerosene increases the phenomenon of porosity of old cables. Degradation characteristics of dielectric strength of the cable insulation explains the appearance of the arc. The accident occurred while the cable was over 19 years old. The fuel pumps wiring has never been a problem. But there has not been a cable that had reached the age of 19 years. The aging of the cable could still degrade the seal. Finally, maintaining this type of cable on the first C160 series until this accident was part of a complex process in which traceability has not been formally established. Doubts indeed appeared in 1969 on the quality of these cables, doubts that can be considered today as precursors. Measures had been adopted precisely to overcome these deficiencies. In this regard, the replacement of the fuel pump wiring of the second series C 160 of these cables with a newer type and considered more efficient is particularly significant. Its extension to the first series aircraft might have seemed relevant, and would probably have prevented the accident. The reasons which led to the maintenance of such cables on the C 160 series first held in both the human factor (underestimation of risk, lack of global view on the issue) and organizational factors, which can be seen as a lack of traceability of technical and logistic actions, a lack of consistency of the measures adopted, and probable deficiencies in the information flow.

Circumstances:
On Monday July 18 1995 at 00h45 UTC, expressed in local time as Sunday July 17 at 20h45, the Trans Island Air Britten-Norman BN2B registered as 8P-TAD, took off from Grantley Adams airport (Barbados) bound for Fort de France (Martinique) with one pilot and five passengers on board. The flight had been preceded by another aircraft, registered as 8P-TAC, of the same type and belonging to the same company, flying the same route. These flights were undertaken on a charter basis on behalf of Société Nouvelle Air Martinique. They were carrying passengers originally scheduled to fly on a Dornier 228 which was out of service, and which was supposed to undertake scheduled flight PN403. At 01h39, at the request of the approach controller, the pilot announced his estimated arrival time over the FOF beacon at 01h47. At 01h40 the pilot said that he was at 2700 feet, thus at the minimum arrival altitude in that sector, still on the 150 radial from FOF; he stated that he had the field in sight and requested permission to make a visual approach. At 01h42, at the request of the controller, the pilot confirmed that he had the field in sight and obtained clearance for a visual approach. At 01h45, the pilot of 8P-TAD transmitted for the last time. At 01h48, he no longer responded to the controller's calls. At 01h58, the DETRESFA phase of the search and rescue procedure was initiated. On July 19 1994 at around 08h30, a day and a half after the accident, the wreckage of the aircraft was found in the Carbet hills, near Piton Lacroix in the
commune of Bellefontaine.
Probable cause:
The accident was caused by the pilot's failure to identify the airdrome installations before the start of the night visual approach procedure under an IFR flight plan. The probable failure of the onboard DME and the imprecise navigation contributed to the accident.

Circumstances:
After takeoff from Fort-de-France-Le Lamentin Airport, the crew informed ATC about technical problems and was cleared to return for an emergency landing. Following an unstable approach, the four engine airplane landed hard. The crew was able to stop the airplane in timely manner and while all three crew members were uninjured, the airplane was damaged beyond repair.

Circumstances:
Flight 216 continued at 6,000 feet until radio bearings indicated its position to be opposite the Fort de France radio beacon at which point it turned to the west, away from the island, preparatory to making a let-down. About 10 miles west of Martinique the plane entered an area clear of clouds and descent was started in wide spiral over the open sea. The co-pilot then established radio communications with the company's base station and at 0955 was advised that landing conditions at Fort do France were: wind ESE 20 knots, visibility 2 miles, ceiling 2,000 feet, barometer 1012.2, sea moderate with ground swells. Landing minimums for Pan American at Fort-de-France, approved by the Civil Aeronautics Administration, are: ceiling 1,000 feet, visibility 2 miles. During the let-down to Fort do France the pilot observed that the clouds extended upwards from 800 feet and that very heavy rain underneath the overcast made it impossible to determine accurately the condition of the water surface. Captain Shaw stated that during the let-down the left engine cut out momentarily and then resumed normal operation with indication of the proper manifold pressure. Instead of encountering the weather conditions reported at 0955, the pilot found that low ceiling and heavy rain squalls prevailed with visibility reduced to about 1/2 mile. Proceeding to Fort-de-France under the overcast, Captain Shaw circled the company station at an altitude of 500 feet and rioted that the wind-sock indicated a southwest surface wind instead of the previously reported east-southeast wind. Remarking to the co-pilot that he was afraid they would "lose" the left engine and, being apprehensive of single-engine performance of the Sikorsky S-43, the pilot elected to risk a landing under his emergency authority. At this moment the company radio advised that the weather was closing in rapidly and a landing should be made as soon as possible. Heading into the southwest wind an approach with full flaps was made toward a portion of Fort-de-France harbor seldom used for landing. Captain Shaw stated that during the latter part of his approach intense rain precluded forward vision through the windshield and only by opening a side window in the cockpit was he able to see the surface of the water just before the plane landed on the crest of a 4 to 6-foot swell. On contact with the water and alarmed by the size of the surface swells, the pilot attempted to take off, using full throttles, but he stated that the left engine failed to respond. The bow submerged and the plane yawed to the right, shearing off the left wing float and permitting that wing to submerge. As the left wing went down the aircraft rolled over on its back, rapidly filling with water. Quick action on the part of the crew resulted in the saving of all but four of the ten passengers, several of whom had to be taken from the plane through the submerged hatch. Survivors were picked up by the company service launch and a private fishing boat. The crash occurred at about 1011 and the plane sank within 10 minutes.
Probable cause:
On the basis of the foregoing the Board determines that the probable cause of this accident was the attempt by the pilot to land the aircraft in conditions of water surface not suitable for landing of a flying boat.
