HISTORY OF FLIGHT

On November 30, 2004, at 1956 central standard time, a Hamburger Flugzeugbau, HFB Hansa 320, N604GA, operated by Grand Aire Express, was destroyed when it impacted the Missouri River near Chesterfield, Missouri, soon after departure from runway 26L (7,485 feet by 150 feet, concrete) at the Spirit of St. Louis Airport (SUS), Chesterfield, Missouri. The pilot and copilot sustained fatal injuries. The 14 CFR Part 91 ferry flight departed SUS en route to the Toledo Express Airport (TOL), Toledo, Ohio. Night visual meteorological conditions prevailed at the time of the accident. The flight was on an instrument flight rules (IFR) flight plan.

The pilot contacted the St. Louis Automated Flight Service Station (AFSS) by telephone at 1504 to file a flight plan from SUS to TOL with a departure time of 1550. At 1615, the pilot contacted the St. Louis AFSS to amend the departure time to 1800. At 1733 and 1736, the pilot called the St. Louis AFSS to obtain information about a runway closure at TOL.

The pilot contacted the St. Louis AFSS at 1934 to re-file the flight plan from SUS to TOL with a new departure time of 2000. The pilot filed for an airspeed of 400 knots with an en route altitude of 33,000 feet. The proposed time en route was 45 minutes, and the pilot indicated that there were 3 hours of fuel on board. When the St Louis AFSS briefer asked the pilot why the aircraft had not departed an hour earlier, the pilot responded, "We had to abort because the airspeed indicator didn't work, but ... it's fixed now."

At 1943, N604GA contacted the SUS Air Traffic Control Tower (ATCT) and received its IFR clearance to TOL. N604GA reported to ATCT that the airplane was positioned at the Millionaire ramp and requested permission to do a high-speed back taxi on runway 26L. At 1950, ATCT authorized N604GA to perform a high-speed back taxi on the runway, and to position and hold on the runway once the back taxi was complete.

At 1954, ATCT cleared N604GA for takeoff. At 1955, ATCT instructed N604GA to contact departure control, but there was no response from N604GA.

The St. Louis Approach control radar recorded six "hits" of radar track data as N604GA departed to the west. The radar track data indicated that at 1955:33, N604GA initially climbed to about 900 feet mean sea level (msl) with a ground speed of about 180 kts. The radar track data indicated that the airplane continued on a westerly heading. The last recorded radar contact with N604GA at 1955:51 indicated the airplane's altitude was about 600 feet msl with a ground speed of about 190 kts.

Witnesses who observed the airplane's departure reported that the engines sounded like they were at "full throttle" during the takeoff roll and climb. They reported seeing the airplane drift to the right during climbout and then the airplane started to lose altitude. The witnesses reported the engines continued to sound like they were at high power, and then there was silence followed by the sound of terrain impact.

A search for N604GA was initiated immediately, but due to poor weather conditions and the dark night, the airplane was not located until about 0230 on December 1, 2004. The airplane wreckage was located about 2 nautical miles west of SUS along the riverbank of Howell Island, a heavily wooded wildlife sanctuary.

(2) No person or property is carried on board the aircraft, other than necessary for conduct of the flight."

AIRCRAFT INFORMATION

The twin-engine Hamburger Flugzeugbau, HFB Hansa 320, serial number 1037, was manufactured in 1969. The maximum take-off weight was 20,280 pounds. The engines were General Electric CJ-610-5 engines that produced 2,850 pounds of static thrust each. Originally, the airplane had cabin seating for 7 or 8 passengers, but in October 9, 2002, the bench seat was removed per Supplementary Type Certificate (STC) SA01709CH, which configured the airplane to a four passenger corporate jet. The airplane was operated as a personal aircraft of the pilot. The airplane was being operated under FAR Part 91 regulations and was not listed on the FAR Part 135 operating certificate of TriCoastal Air. It was not equipped with a Cockpit Voice Recorder (CVR) or a Flight Data Recorder (FDR).

A Federal Aviation Administration (FAA) airworthiness inspector reviewed the airplane's logbooks and records. The logbooks indicated that the aircraft was issued a Standard Airworthiness Certificate on January 30, 2000, during a recurrent certification. The aircraft had been operated in South America from 1987 to September 1999. The aircraft records did not indicate what inspection program the airplane was being inspected under as required by FAR 91.409 (e) (f). The logbooks indicated that the aircraft was inspected in accordance with the Hansa HFB-320 Inspection Method, and Grand Aire's Approved Aircraft Inspection Program (AAIP). The last 75/300 Hour inspection on the airframe was accomplished on July 10, 2003, with an airframe total time of 6,847.3 hours. The logbook entry signoff indicated that it was inspected in accordance with Grand Aire's AAIP program. The airplane had flown 28.7 hours since the inspection and had a total airframe time of 6,876 hours.

The left engine, serial number E249-109, and the right engine, serial number 240B-249A, were installed on the airplane on March 10, 2004, at a total airframe time of 6,874.7 hours. The aircraft logbooks indicated that the altimeters, pitot static system, and transponders were recertified on March 10, 2004. A 1.3-hour functional test flight of the airplane's engines was conducted on March 23, 2004, when the airplane was flown from TOL to SUS. The airplane was not flown again until the accident flight on November 30, 2004.

According to witnesses at SUS, the airplane was initially parked on the Thunder Aviation's satellite ramp. The airplane developed a fuel leak so the airplane was moved to another location on the airport with a concrete parking ramp. The airplane stopped leaking so it was not de-fueled. Witnesses reported that the airplane was equipped with engine inlet covers and a windshield cover, but no covers for the pitot tubes. The windshield cover was eventually removed since it kept getting blown off by the wind.

In July 2004, the Director of Maintenance at TriCoastal Air requested that Midcoast Aviation, located at SUS, perform the maintenance required by the FAA Airworthiness Directive (AD) 2004-01-11, "Replace Elevator Trim Cables." The shop manager at Midcoast Aviation reported that the shop could perform the maintenance, but delayed that work until the shop had more time to complete the maintenance, and received the required maintenance manuals from TriCoastal Aviation.

Midcoast Aviation started the maintenance necessary to comply with AD 2004-01-11 about September 7, 2004. After receiving new elevator trim cables and other serviceable parts associated with the elevator trim system, the mechanics at Midcoast Aviation performed the maintenance specified in the AD. The Midcoast maintenance Discrepancy Sheet, page 3 of 14, dated September 24, 2004, stated the following maintenance write-up:

"Removed vertical panels to gain access troughs [Initials JD] 9-7-04 Disconnected elevator trim cables at turnbarrels. Removed cable guard pins at all double pulleys, (8 pins total of 4 pulley pairs). Pulled cables off pulley and to drums. Removed lower drum per HFB 320 M.M. 27-31-0. Removed upper drum assy per HFB 320 M.M. 27-31-0. [Initials] 9-7-04. Unspooled cable drums + inspected drums 9-8-04. Sent old cables out to Beechhurst Industries to manufacture new cables @ proper length. Received proper cables on 9/23/04, [Initials] Wrapped new cables on respective cable drums & installed in aircraft. Ran cables thru four sets of pulleys & installed cable guards (8 ea). Connected lower cables to upper cables w/ turnbarrels & set proper tension & saftied. Painted each turnbarrel & terminal ends green & red respectively. Performed operational test as required. Ops test good. Reinstalled panels previously removed. 9/24/04, [Initials] AD 2004-01-11 complied with. 9/24/04 [Initials]"

The 9/24/04 Discrepancy Sheet entry was signed by a Midcoast Aviation's technician and the lead inspector. Because the maintenance involved a flight control system, a Midcoast Required Inspection (MRI) was also performed by a Midcoast MRI inspector. After Midcoast performed AD 224-01-11, the aircraft was towed back to the satellite ramp.

The airplane sat on the satellite ramp until November 30, 2004. The Midcoast Aviation maintenance manager at SUS reported that the Director of Maintenance of TriCoastal Air contacted him on November 17, 2004, and requested that Midcoast Aviation perform a standby compass swing, an avionics check, and to deep cycle the aircraft's batteries. The manager informed him that Midcoast did not have the time available to conduct a compass swing or an avionics check, but the batteries were removed and sent to a battery shop to have them deep cycled. The batteries failed the deep cycle test.

The Midcoast maintenance manager reported that the Director of Maintenance of TriCoastal Air contacted him on November 29, 2004, and requested again that Midcoast Aviation perform a standby compass swing, an avionics check, and attempt to start the engines. He also informed the Midcoast manager that pilots would be arriving the next day to fly the airplane back to TOL, and that a set of batteries were being shipped to Midcoast that would arrive the next day, November 30, 2004.

The Midcoast maintenance manager reported that on November 30, 2004, he and another technician from Midcoast started the engines with a set of "loaner" batteries and ran the engines for about 25 minutes before taxiing the airplane to Midcoast Aviation's ramp. He reported that they taxied to the ramp about 1245, and the pilots had arrived and were waiting at the hangar. The batteries being shipped from TriCoastal Air did not arrive until 1630. He reported that the copilot performed a walk around while waiting for the batteries to arrive. Once the batteries arrived, they were installed in the aircraft.

The Midcoast maintenance manager reported that the pilot informed him that the flight back to TOL was a ferry flight, and that a Special Ferry Permit needed to be signed. It was the first time that the maintenance manager was informed that the flight was a ferry flight that would require a signature from an Airframe and Powerplant (A&P) mechanic or a Repair Station certifying in the aircraft records that the aircraft was safe for the intended flight.

The Special Flight Permit issued by the FAA on November 29, 2004, stated the following Operating Limitations:

"This authorization expires upon arrival at destination or 12/8/2004.
