AOAR, 1992, Revision 3, as well as the effective Air Navigation Certificate issued to Sochi
aerodrome.
1.10 Aerodrome Information
1.10.1. Sochi aerodrome is of Class B and has two intersecting paved runways, a network of
taxiways, a parking area and a ramp.
The primary runway is a Class B paved runway 1 2890 m x 50 m, with MH 60/240. It was built
in 1956, then overhauled and extended in 1984 for the purpose of IL-86 airplane operation.
The secondary runway is a Class B paved runway, 2200 m x 50 m, with MH 24/204, built in
1972.
This is a “mountain” aerodrome, with the runways requiring take off towards the sea: MHto=240º
and MHto=204º and approach from the sea: MHland=60º and MHland=24º.
According to the certificate issued by the IAC Aviation Register, the aerodrome is suitable for
international flights and not restricted.
This is a mixed aerodrome shared with the Ministry of Defense of the Russian Federation.

RW-1 is of a rigid type, paved with two-ply concrete with 0.2+0.22 m thickness, the surface
classification number is PCN 29 /R/A/W/T/.
RW-2 is also of a rigid type, paved with one-ply concrete, the surface classification number is
PCN 29 /R/A/W/T/.
The aerodrome pavement has defects by way of jagged full-depth cracks, longitudinal and lateral
cracks with rough edges, and the upper layer of the paving is flaking off. The surface would
benefit from repair.
The aerodrome drain system, which provides collection and discharge of the surface water from
the area, consists of rain-collecting wells and manifold mains that discharge the unfiltered waste
water in the Pervinka river. Currently there is no waste water treatment facility.
The physical aerodrome characteristics are in compliance with the Civil Aerodrome Operational
Regulations of the RF, 1994.
1.10.2. Runway condition
Inspection of the aerodrome surface and the runways was carried out in accordance with the Civil
Aerodrome Operation Guidance of the Russian Federation, 1994.
The inspection results was recorded in the Airfield Condition Logbook kept at the aerodrome
control tower.
1.10.3. Aerodrome support
Aerodrome support was provided in accordance with the ICAO Chicago Convention, Annex 14,
AOAR, Revision 3, 1992, Appendices 1, 3 and 4 and the effective Civil Aerodrome Operation
Guidance.
1.11 Flight Recorders (FDR and CVR)
A320 EK-32009 was equipped with an Allied Signal 4700 FDR and a Sundstrand AV-557-C
CVR, which were installed in the rear part of fuselage. When the airplane impacted the water and
was destroyed, both recorders were torn out of their installations.
The recorders were equipped with radio beacons that were activated when they hit the water.
Work was undertaken to locate the radio beacon signals. According to preliminary conclusion,
the radio beacons were located within a triangle with 150-meter sides. With the use of highprecision
measurement equipment, the precise radio-beacon coordinates were determined as: 43°
22.9812 N; 39° 51.6875 E and 43° 22.9777 N; 39° 51.6871 E at a depth of 496.5 m.
On 22.05.2006, in course of the search in the specified area, the Sundstrand AV-557-C CVR was
found and recovered. The Allied Signal 4700 FDR was found 40 m away from the CVR and was
recovered on 24.05.2006.
The both recorders had suffered only minor damage, and after external inspection they were
packed in containers with water, sealed and sent for further inspection.
Flight Data Recorder
The Allied Signal 4700 FDR registers the flight data for the previous 25 hours.

The FDR casing had minor mechanical damage and bore no traces of thermal influence.
The opening of the FDR, assessment of its status and read out of the data from the damaged
medium were conducted by BEA specialists in France. Further processing and analysis of the
retrieved data was performed with the use of the computerized WinArm32™ system in the
Commission on Scientific and Technical Support to Aviation Accident Investigation of the IAC.
The Allied Signal 4700 FDR was serviceable and recorded all parametric data on 2 May 2006
until 22:13:02:08, in accordance with the List of Parameters for A320 EK-32009. The recording
quality was good. The system stopped recording due to a cut in electrical power supply, when the
airplane was destroyed.
Cockpit Voice Recorder
The Sundstrand AV-557-C CVR records audio information in three channels (the left cockpit
seat, the right seat and the cockpit area microphone) and records the last 30 min of flight.
The CVR casing was mechanically damaged, but bore no traces of thermal influence.
