Socata TBM-700

The airplane, registered to SV Leasing Company of Florida, operated by SOCATA North America, Inc., sustained substantial damage during a forced landing on a highway near Hollywood, Florida, following total loss of engine power. Visual meteorological conditions prevailed at the time and an instrument flight rules (IFR) flight plan was filed for the 14 Code of Federal Regulations (CFR) Part 91 maintenance test flight from North Perry Airport (HWO), Hollywood, Florida. The airline transport pilot and pilot-rated other crew member sustained minor injuries; there were no ground injuries. The flight originated from HWO about 1216. The purpose of the flight was a maintenance test flight following a 600 hour and annual inspection. According to the right front seat occupant, in anticipation of the flight, he checked the fuel load by applying electrical power and noted the G1000 indicated the left fuel tank had approximately 36 gallons while the right fuel tank had approximately 108 gallons. In an effort to balance the fuel load with the indication of the right fuel tank, he added 72.4 gallons of fuel to the left fuel tank. At the start of the data recorded by the G1000 for the accident flight, the recorded capacity in the left fuel tank was approximately 105 gallons while the amount in the right fuel tank was approximately 108 gallons. The PIC reported that because of the fuel load on-board, he could not see the level of fuel in the tanks; therefore, he did not visually check the fuel tanks. By cockpit indication, the left tank had approximately 105 gallons and the right tank had approximately 108 gallons. The flight departed HWO, but he could not recall the fuel selector position beneath the thrust lever quadrant. He further stated that the fuel selector switch on the overhead panel was in the "auto" position. After takeoff, the flight climbed to flight level (FL) 280, and levelled off at that altitude about 20 minutes after takeoff. While at that altitude they received a "Fuel Low R" amber warning CAS message on the G1000. He checked the right fuel gauge which indicated 98 gallons, and confirmed that the fuel selector automatically switched to the left tank. After about 10 seconds the amber warning CAS message went out. He attributed the annunciation to be associated with a failure or malfunction of the sensor, and told the mechanic to write this issue down so it could be replaced after the flight. The flight continued and they received an amber warning CAS message, "Fuel Unbalance" which the right fuel tank had more fuel so he switched the fuel selector to supply fuel from the right tank to the engine. The G1000 indicates they remained at that altitude for approximately 8 minutes. He then initiated a quick descent to 10,000 feet mean sea level (msl) and during the descent accelerated to Vmo to test the aural warning horn. They descended to and maintained 10,000 feet msl for about 15 minutes and at an unknown time, they received an amber warning CAS message "Fuel Low R." Once again he checked the right fuel gauge which indicated it had 92 gallons and confirmed that the fuel tank selector automatically switched to the left tank. After about 10 seconds the CAS message went out. Either just before or during descent to 4,000 feet, they received an amber CAS message "Fuel Unbalance." Because the right fuel gauge indicated the fullest tank was the right tank, he switched the fuel selector to supply fuel to the engine from the right tank. The flight proceeded to the Opa-Locka Executive Airport, where he executed an ILS approach which terminated with a low approach. The pilot cancelled the IFR clearance and proceeded VFR towards HWO. While in contact with the HWO air traffic control tower, the flight was cleared to join the left downwind for runway 27L. Upon entering the downwind leg they received another amber CAS message "Fuel Unbalance" and at this time the left fuel gauge indicated 55 gallons while the right fuel gauge indicated 74 gallons. Because he intended on landing within a few minutes, he put the fuel selector to the manual position and switched to the fullest (right) tank. Established on final approach to runway 27L at HWO with the gear down, flaps set to landing, and minimum speed requested by air traffic for separation (85 knots indicated airspeed). When the flight was at 800 feet, the red warning CAS message "Fuel Press" illuminated and the right seat occupant with his permission moved the auxiliary fuel boost pump switch from "Auto" to "On" while he, PIC manually moved the fuel selector to the left tank. In an effort to restore engine power he pushed the power lever and used the manual over-ride but with no change. Assured that the engine had quit, he put the condition lever to cutoff, the starter switch on, and then the condition lever to "Hi-Idle" attempting to perform an airstart. At 1332:42, a flight crew member of the airplane advised the HWO ATCT, "…just lost the engine"; however, the controller did not reply. The PIC stated that he looked to his left and noticed a clear area on part of the turnpike, so he banked left, and in anticipation of the forced landing, placed the power lever to idle, the condition lever to cutoff, the fuel tank selector to off, and put the electrical gang bar down to secure the airplane's electrical system. He elected to retract the landing gear in an effort to shorten the landing distance. The right front seat occupant reported that the airplane was landed in a southerly direction in the northbound lanes of the Florida Turnpike. There were no ground injuries.

The accident flight was the final one of a series of sales demonstration flights. The demonstration pilot occupied the right seat and a potential customer was handling the aircraft from the left seat. The handling pilot was qualified and current on helicopters but had only 100 hours of fixed wing flying experience and had not flown a fixed wing aircraft as-pilot-in-command for some eight years; he controlled the aircraft throughout the flight, under the instruction of the demonstration pilot. After some general handling, including turns and a demonstration of the final approach configuration, F-GLBD returned to the local circuit. The first approach to runway 20 was slightly steep and the landing was firm but satisfactory. During the ground roll the demonstration pilot reconfigured the aircraft and the handling pilot applied power and made a take-off for another circuit. The second approach which was for a final landing was initially stable and on the glideslope. However, on short finals the aircraft went below the glideslope and the nose attitude was too high. There was a crosswind from the right and F-GLBD was on the left of the extended centerline. The demonstration pilot put his left hand on the power lever below that of the handling pilot and, as he did so, told the handling pilot to increase power. When no power was apparent the demonstration pilot repeated his instruction and also applied pressure to the power lever. As the aircraft approached the flare the handling pilot released the power lever and put both hands on the control wheel; the power lever moved quickly to the fully open position under the hand pressure of the demonstration pilot. The aircraft rolled rapidly to approximately 20° to 30° angle of bank to the left and the demonstration pilot took control with both hands on the control wheel. However, the left wing tip and the outboard trailing edge of the left flap struck the ground; the wing tip impact mark was off the runway to the left and the flap impact mark was just on the runway. The left main wheel then made contact with the runway, closely followed by the right main wheel. As the aircraft left the runway at an angle of approximately 230° to the left, the demonstration pilot closed the power lever, the aircraft continued across the grass for a distance of approximately 350 metres. It passed through and destroyed part of the PAPI installation, crossed runway 30 and came to a stop. At the time of the accident, it was dark and the weather was good; the surface wind was 230°/5 knots. All six occupants escaped uninjured and the aircraft was damaged beyond repair.

The crew was completing a test flight from Toussus-le-Noble to Epinal. On approach to Epinal-Mirecourt Airport, visibility was below minimums. On final, as the crew was unable to locate the runway, he decided to initiate a go-around procedure and increased engine power. The aircraft rolled to the left, causing the left wing and the engine to struck the runway surface. Power was reduced and the aircraft bounced and eventually came to rest 400 metres further. Both occupants were injured and the aircraft was damaged beyond repair.
