The pilot reportedly did an unusual amount of engine run-up before pulling onto the runway. He then performed another run-up before departing. This is evidence that he was aware of a problem with his aircraft. The engine(s) were popping and puffing black smoke during the ground run. Yet, the takeoff was continued. The popping and smoke puffing continued after liftoff. A noticeable loss of airspeed occurred during the climbout. The aircraft started the third roll (into the bad engine) before finally going inverted. The aircraft's allowable gross weight was exceeded by at least 205 pounds at takeoff, however, the center of gravity remained within its specified limits. Internal examination of the right engine exhibited evidence that it had operated at sometime on a mixture of gasoline and jet fuel. All six occupants were killed.

The pilot received a weather briefing indicating IMC conditions existed at the point of departure and at reporting stations near the point of the first intended landing (there was no reporting stations at the airport of intended landing). Weather conditions changed to VMC at the departure point and the pilot was cleared for takeoff on a special VFR departure. The pilot continued VFR flight for about 55 statute miles and collided with a 500 foot radio antenna at a point about 350 feet above the ground. The antenna was on a direct line between the points of departure and intended landing. The pilot reportedly was navigating by loran radio. Witnesses reported the upper half of the impacted antenna was obscured by fog when the accident occurred. Witnesses reported the visibility to be about one mile. The pilot, sole on board, wa killed.

The pilot initiated an ILS approach in below minimum weather conditions shortly after night fall. He was given a low altitude alert, but continued the approach. He announced a missed approach, and indicated problems climbing to altitude. He then declared an unspecified emergency, and requested vectors to a larger airport, in spite of worsening weather conditions. He reached an altitude of 2,100 feet, but commenced another ILS approach despite previous difficulties. Radar data indicates excessive maneuvering to intercept the inbound course, with wide variations in ground speed and altitude. Following a steep climb at a low groundspeed, the aircraft disappeared below radar coverage. Witnesses indicated irregular engine sounds as the aircraft made a tight level turn at low altitude prior to impacting trees in a near level attitude. On-scene evidence shows power was being produced from both engines upon impact. Post-impact fire consumed the wreckage. Both occupants were killed.

A distress message was received from the pilot stating he was 100 miles south of Grand Isle, LA, and had lost an engine and was unable to maintain altitude. A second message was received shortly afterwards stating that the aircraft was at 1,500 feet and the pilot was preparing to ditch the aircraft. No further contacts and no ELT signals were heard. The aircraft wreckage has not been located.

A popping or backfiring sound was heard by several people who later observed the aircraft flying at low altitude on what appeared to be a final approach to runway 13 at Jennings Airport (located about 75 miles southwest of the departure point.) No radios were onboard the aircraft so no distress calls were made. Because of the wind this would have been a downwind landing. The aircraft then aborted the approach due to an aircraft landing from the opposite direction and appeared to start a left turn onto abase leg when it stalled, pitched nose down and impacted the ground with its landing gear and flaps extended. Wreckage examination revealed that all 3 blades of the right prop were bent smoothly and symmetrically rearward. However, no preimpact failure or malfunction of the right engine was found. There were no entries in the aircraft's logbook from 7/1/78 until 4/3/84 when the aircraft was inspected for the ferry flight. The pilot was not multi-engine rated and had not flown this type aircraft in about 10 years. The pilot's commercial certificate was revoked on 11/21/81. The pilot, sole on board, was killed.

While descending into the Patterson area on an IFR flight plan, the pilot was cleared to hold and was advised that he would be the #2 aircraft for an approach to the Patterson Airport. A few minutes later the pilot asked how long the delay would be. He subsequently stated he had the airport, cancelled IFR and was going in VFR. A pilot who had just departed the airport heard a Mitsubishi call 'turning base.' He could not see an aircraft on base for runway 05. He called but did not receive a reply. The aircraft contacted trees along a heading of about 225°. The flaps were extended about 5° and the landing gear were extended. All three occupants were killed.

Witnesses reported that when the aircraft was stabilized on final approach, it pitched up slightly and yawed, then rolled left to an inverted attitude and crashed in a canal. Several witnesses stated that the left prop was windmilling. One stated the left prop had stopped. Two others said smoke was trailing from the aircraft. One witness stated that after the aircraft passed over his car, a fine mist of oil fell on his windshield. When the aircraft was recovered from the canal, the left prop was found in the feathered position while the right prop was near its low pitch stops. The left prop dome was found depleted of air pressure and no oil was found in the left engine case. Also, an oil film was found on the bottom of the left eng, left flap and left stabilizer. A further exam revealed that an oil interconnect line, Piper pn: 920024-811, had failed inside its fireproof covering. The hose was 8 years old, its recommended replacement interval was 5 years. It had been installed with a small bend radius. Also, the left engine had evidence of heat and wear due to lack of oil.

The aircraft crashed and burned shortly after taking off in darkness on an IFR flight plan. The weather was reported as indefinite ceiling, zero obscuration, visibility 1/4 mile with fog, wind 120° at 5 knots. A number of witnesses heard the aircraft, both before and after takeoff. The consensus of their statements indicated that one engine lost power while the other continued running at a high power setting. An investigation revealed that an intense post crash fire had consumed most of the aircraft. There was evidence that the plane had crashed in a steep nose down, right wing low attitude and did not move after impact. The right propeller was found in a feathered position. The left propeller blades were curled and twisted. Both engines were disassemble, but no evidence of a mechanical failure was found. The gear and flaps were retracted and the cowl flaps were closed. All three occupants were killed.

Pan Am Flight 759 was a scheduled flight from Miami (MIA) to Las Vegas (LAS), with an en route stop at New Or1eans (MSY). At 15:58:48 Boeing 727 "Clipper Defiance" taxied from its gate at the New Orleans International Airport. Before leaving the gate, the flightcrew had received ATIS message Foxtrot which read in part "....time one eight five five Zulu, weather, two thousand five hundred scattered, two five thousand thin broken, visibility six miles in haze, temperature niner zero, wind two four zero at two, winds are calm altimeter three zero zero one...". The flightcrew requested runway 10 for the takeoff and ground control cleared the flight to taxi to runway 10. At 15:59:03, the first officer requested a wind check. Winds were 040 degrees at 8 knots. At 16:02:34, while Flight 759 was taxiing to runway 10, the crew heard a transmission from ground control, advising another airplane of low level wind shear alerts in the northeast quadrants of the airport. At 16:03:33, the first officer requested another wind check. Ground control replied, "Wind now zero seven zero degrees at one seven... peak gusts two three, and we have low level wind shear alerts all quadrants, appears to be a frontal passing overhead right now, we're right in the middle of everything." The captain then advised the first officer to "...let your airspeed build up on takeoff..." and said that they would turn off the air conditioning packs for the takeoff, which would enable them to increase the EPR's on engines Nos. 1 and 3 to 1.92. The flightcrew completed the takeoff and departure briefings and turned onto the active runway for takeoff. At l6:06:22, Flight 759 informed the tower that it was ready for takeoff. The local controller cleared the flight for takeoff, and the first officer acknowledged the clearance. About 16:07:57, the Boeing 727 began its takeoff. According to witnesses, the airplane lifted off about 7,000 feet down runway 10, climbed in a wings-level attitude, reached an altitude of about 100 feet to 150 feet above the ground (AGL), and then began to descend towards trees. The airplane crashed into a residential area and was destroyed during the impact, explosion, and subsequent ground fire. Eight persons on the ground were killed.

The passenger stated that after sharp turns at low altitude over a farm house they did a roll and were too low to recover prior to striking trees. The aircraft came to rest inverted in a 4-5 feet deep farm pond. The autopsy report shows the pilot's death by asphyxia due to drowning. The passenger also stated they had also flown low over a beach and performed a roll enroute from pine bluff.
