HISTORY OF FLIGHT

On February 13, 2001, at 1840 central standard time, a Cessna 421, N5AY, owned and operated by a private operator, collided with the southeast bank of Choccolocco Creek near Munford, Alabama, while maneuvering for a visual approach and landing to the Talladega Airport in Talladega, Alabama. The business flight was operated under the provisions of Title 14 CFR Part 91 with an instrument flight plan filed. At the time of the accident the instrument flight plan had been canceled. Instrument meteorological conditions prevailed at the time of the accident. The airplane was destroyed, and the pilot and four passengers were fatally injured. The flight departed Hamilton, Ohio, at 1557.

The pilot and passengers were returning to Talladega, Alabama, after a business meeting in Ohio. The pilot filed an IFR flight plan to Anniston, Alabama, before leaving Hamilton, Ohio. While en route at 1557 hours, air traffic control (ATC) advised the pilot of N5AY that the airplane's transponder was not working. ATC requested position reporting from N5AY during the flight.

At 1816:25, Birmingham Approach Control received N5AY as a non-radar handoff from Atlanta Center, eight miles northeast of Gadsden, Alabama. At 1817:44, the pilot of N5AY radioed Birmingham Approach to report descending from seven thousand two hundred to six thousand. At 1820:04, the pilot advised the controller of intentions for the ILS approach for runway 5 at Anniston, Alabama. The pilot was issued radar vectors and instructed to join the seven-mile arc. At 1825:04, Birmingham Approach instructed N5AY to descend to 4,000 feet. At 1830:06, Birmingham Approach stated, "N5AY, as soon as you're established on the seven-mile arc, descend and maintain three thousand until passing clark intersection, and you're cleared for the ILS five approach to Anniston."

At 1830:18, the pilot of N5AY replied, "Uh, roger, understand we're descending to three thousand at this time and cleared for the ILS five approach." At 1834:11, the pilot canceled the instrument flight plan and was asked by the controller if the airplane was below the weather. The pilot replied, "Uh, that's affirmative, and, uh, we're going to turn back to Talladega, that's where our intended place was, we just filed Anniston because they had an ILS." At 1834:30, radar service was terminated.

At 1842, local residents in the immediate vicinity of the accident site heard what was described as a "loud boom." A witness saw what he described as a "large fire," and immediately telephoned 911. Another witness who heard the accident went with a friend to the location of the fire and found the downed airplane.

The Cessna 421, N5AY, was owned and operated by the commercial pilot. N5AY was a twin-engine airplane powered by two Continental GTSIO-520-D engines. The aircraft logbooks showed that the last annual inspection was completed on February 2, 2001.

METEOROLOGICAL INFORMATION

At 1521, the pilot received a routine weather briefing from Dayton Flight Service Station for an IFR flight to Anniston, Alabama. The Anniston airport 1817 surface observation reported 2 miles visibility, 200 feet overcast, wind 070 degrees at 6 knots. The Anniston terminal aerodrome forecast issued at 1730 for the period between 1730 and 2200 hours reported 1 1/2 miles visibility, mist, 400 foot overcast ceiling; temporarily between 1800 and 2200 hours, 1/2 mile visibility, fog , 100 overcast ceiling.

WRECKAGE AND IMPACT INFORMATION

Examination of the accident site disclosed that airplane wreckage debris was scattered over an area approximately 150 long and 25 feet wide. The aircraft wreckage site was located 5.43 nautical miles east Talladega Airport. Wreckage debris was oriented perpendicular to a berm that was oriented on a 240-degree magnetic heading. The main wreckage rested at the waterline of Choccolocco Creek. The airplane was broken into several pieces and was submerged or embedded into the bank of the creek.

Examination of the cockpit revealed damage to the cockpit flight instruments and cockpit switches. Examination of the airspeed indicator revealed 110 knots. Examination of the Vertical speed indicator indicated a 1000 foot per minute decent. Examination of the left tachometer needle indicated 2100 rpm. All other instruments were damaged.

Examination of the wing assembly revealed that the left and right wing aileron flight control surfaces were destroyed. The right out board flap separated from the wing. The right inboard flap was connected with two actuating rods. The left inboard and outboard flaps were attached and both actuating rods were attached.

Examination of the landing gear revealed the right main landing gear was down and locked. The left main gear was extended, but was not in the locked position. The nose gear was extended. The landing gear actuator bellcrank was in the retracted position.

Examination of the empennage section revealed that it was attached to the tailcone. The left horizontal stabilizer leading edge exhibited some leading edge damage. The left elevator showed buckling along the trailing edge span. The right horizontal stabilizer appeared undamaged. The right elevator was not connected to the horizontal stabilizer at the out board hinge. Examination of the 4 elevator cables showed that they were attached to the aft elevator bellcrank. Movement of the elevator actuated the aft elevator bellcrank. Examination of the vertical stabilizer showed a semi-circular dent above the fuselage. The rudder and trim tab assemblies were attached to the vertical stabilizer. The rudder cables were attached to the rudder horn and the rudder cables were also attached at the rudder tubes.

Examination of the engines reveal that both engines separated from the airplane and were lodged in the river bank. Examination of the left engine revealed the fuel pump coupling intact. The fuel pump rotated by hand. Examination of the left engine fuel screen revealed that the screen was clean and wet with fuel. The left engine crankshaft was rotated 360 degrees. Both magnetos for the left engine had been damaged.

Examination of the right engine revealed the fuel pump coupling intact. The fuel pump rotated by hand. Examination of the right engine fuel screen revealed that the screen was clean and wet with fuel. Examination of the right engine revealed that all the pistons were normal and both magnetos sparked. Left and right engines both showed valve train continuity.

Both propellers were separated from the engines. Both propellers showed chord-wise damage and twist to blade tips. Examination of the vacuum pumps drive couplings were intact. All other accessories were damaged in the impact. The wreckage examination failed to disclose any mechanical or component failure. The pilot did not report any mechanical problems prior to the accident.

MEDICAL AND PATHOLOGICAL INFORMATION
